Images may be strip- or tile-based and have a variety of different characteristics: bits/sample, samples/pixel, photometric, etc. Decoding state is encapsulated in a .I TIFFRGBAImage structure making it possible to capture state for multiple images and quickly switch between them. The target raster format can be customized to a particular application's needs by installing custom routines that manipulate image data according to application requirements. .PP The default usage for these routines is: check if an image can be processed using .IR TIFFRGBAImageOK , construct a decoder state block using .IR TIFFRGBAImageBegin , read and decode an image into a target raster using .IR TIFFRGBAImageGet , and then release resources using .IR TIFFRGBAImageEnd . .I TIFFRGBAImageGet can be called multiple times to decode an image using different state parameters. If multiple images are to be displayed and there is not enough space for each of the decoded rasters, multiple state blocks can be managed and then calls can be made to .I TIFFRGBAImageGet as needed to display an image. .PP The generated raster is assumed to be an array of .I width times .I height 32-bit entries, where .I width must be less than or equal to the width of the image (\c .I height may be any non-zero size). If the raster dimensions are smaller than the image, the image data is cropped to the raster bounds. If the raster height is greater than that of the image, then the image data are placed in the lower part of the raster. (Note that the raster is assume to be organized such that the pixel at location (\fIx\fP,\fIy\fP) is \fIraster\fP[\fIy\fP*\fIwidth\fP+\fIx\fP]; with the raster origin in the .B lower-left hand corner.) .PP Raster pixels are 8-bit packed red, green, blue, alpha samples. The macros .IR TIFFGetR , .IR TIFFGetG , .IR TIFFGetB , and .I TIFFGetA should be used to access individual samples. Images without Associated Alpha matting information have a constant Alpha of 1.0 (255). .PP .I TIFFRGBAImageGet converts non-8-bit images by scaling sample values. Palette, grayscale, bilevel, .SM CMYK\c , and YCbCr images are converted to .SM RGB transparently. Raster pixels are returned uncorrected by any colorimetry information present in the directory. .PP The parameter .I stopOnError specifies how to act if an error is encountered while reading the image. If .I stopOnError is non-zero, then an error will terminate the operation; otherwise .I TIFFRGBAImageGet will continue processing data until all the possible data in the image have been requested. .SH "ALTERNATE RASTER FORMATS" To use the core support for reading and processing .SM TIFF images, but write the resulting raster data in a different format one need only override the ``\fIput methods\fP'' used to store raster data. These methods are are defined in the .I TIFFRGBAImage structure and initially setup by .I TIFFRGBAImageBegin to point to routines that pack raster data in the default .SM ABGR pixel format. Two different routines are used according to the physical organization of the image data in the file: .IR PlanarConfiguration =1 (packed samples), and .IR PlanarConfiguration =2 (separated samples). Note that this mechanism can be used to transform the data before storing it in the raster. For example one can convert data to colormap indices for display on a colormap display. .SH "SIMULTANEOUS RASTER STORE AND DISPLAY" It is simple to display an image as it is being read into memory by overriding the put methods as described above for supporting alternate raster formats. Simply keep a reference to the default put methods setup by .I TIFFRGBAImageBegin and then invoke them before or after each display operation. For example, the .IR tiffgt (1) utility uses the following put method to update the display as the raster is being filled: .sp .nf .ft C static void putContigAndDraw(TIFFRGBAImage* img, uint32* raster, uint32 x, uint32 y, uint32 w, uint32 h, int32 fromskew, int32 toskew, unsigned char* cp) { (*putContig)(img, raster, x, y, w, h, fromskew, toskew, cp); if (x+w == width) { w = width; if (img->orientation == ORIENTATION_TOPLEFT) lrectwrite(0, y-(h-1), w-1, y, raster-x-(h-1)*w); else lrectwrite(0, y, w-1, y+h-1, raster); } } .ft R .fi .sp (the original routine provided by the library is saved in the variable .IR putContig .) .SH "SUPPORTING ADDITIONAL TIFF FORMATS" The .I TIFFRGBAImage routines support the most commonly encountered flavors of .SM TIFF. It is possible to extend this support by overriding the ``\fIget method\fP'' invoked by .I TIFFRGBAImageGet to read .SM TIFF image data. Details of doing this are a bit involved, it is best to make a copy of an existing get method and modify it to suit the needs of an application. .SH NOTES Samples must be either 1, 2, 4, 8, or 16 bits. Colorimetric samples/pixel must be either 1, 3, or 4 (i.e. .I SamplesPerPixel minus .IR ExtraSamples ). .PP Palette image colormaps that appear to be incorrectly written as 8-bit values are automatically scaled to 16-bits. .SH "RETURN VALUES" All routines return 1 if the operation was successful. Otherwise, 0 is returned if an error was encountered and .I stopOnError is zero. .SH DIAGNOSTICS All error messages are directed to the .IR TIFFError (3TIFF) routine. .PP .BR "Sorry, can not handle %d-bit pictures" . The image had .I BitsPerSample other than 1, 2, 4, 8, or 16. .PP .BR "Sorry, can not handle %d-channel images" .

This includes the ability to translate different color spaces and photometric interpretation into RGBA, support for alpha blending, and translation of many different bit depths into a 32bit RGBA image. .P Internally this program is implemented using the .I TIFFReadRGBAImage() function, and it suffers any limitations of that image. This includes limited support for > 8 BitsPerSample images, and flaws with some esoteric combinations of BitsPerSample, photometric interpretation, block organization and planar configuration. .P The generated images are stripped images with four samples per pixel (red, green, blue and alpha) or if the .B \-n flag is used, three samples per pixel (red, green, and blue). The resulting images are always planar configuration contiguous.

Applications only need to call .IR TIFFWriteDirectory when writing multiple subfiles to a single .SM TIFF file. .IR TIFFWriteDirectory is automatically called by .IR TIFFClose and .IR TIFFFlush to write a modified directory if the file is open for writing. .PP The .IR TIFFRewriteDirectory function operates similarly to .IR TIFFWriteDirectory, but can be called with directories previously read or written that already have an established location in the file. It will rewrite the directory, but instead of place it at it's old location (as .IR TIFFWriteDirectory would) it will place them at the end of the file, correcting the pointer from the preceding directory or file header to point to it's new location. This is particularly important in cases where the size of the directory and pointed to data has grown, so it won't fit in the space available at the old location. .PP The .IR TIFFCheckpointDirectory writes the current state of the tiff directory into the file to make what is currently in the file readable. Unlike .IR TIFFWriteDirectory, .IR TIFFCheckpointDirectory does not free up the directory data structures in memory, so they can be updated (as strips/tiles are written) and written again. Reading such a partial file you will at worst get a tiff read error for the first strip/tile encountered that is incomplete, but you will at least get all the valid data in the file before that. When the file is complete, just use .IR TIFFWriteDirectory as usual to finish it off cleanly. .SH "RETURN VALUES" 1 is returned when the contents are successfully written to the file. Otherwise, 0 is returned if an error was encountered when writing the directory contents. .SH DIAGNOSTICS All error messages are directed to the .IR TIFFError (3TIFF) routine. .PP .BR "Error post-encoding before directory write" .

By default, each row of data in the resultant .SM TIFF file is 1-dimensionally encoded and padded or truncated to 1728 pixels, as needed. The resultant image is a set of low resolution (98 lines/inch) or medium resolution (196 lines/inch) pages, each of which is a single strip of data. The generated file conforms to the .SM TIFF Class F (\c .SM FAX\c ) specification for storing facsimile data. This means, in particular, that each page of the data does .B not include the trailing .I "return to control" (\c .SM RTC\c ) code; as required for transmission by the .SM CCITT Group 3 specifications. The old, ``classic'', format is created if the .B \-c option is used. (The Class F format can also be requested with the .B \-f option.) .PP The default name of the output image is .IR fax.tif ; this can be changed with the .B \-o option. Each input file is assumed to be a separate page of facsimile data from the same document. The order in which input files are specified on the command line is the order in which the resultant pages appear in the output file. .SH OPTIONS Options that affect the interpretation of input data are: .TP .B \-3 Assume input data is .SM CCITT Group 3 encoded (default). .TP .B \-4 Assume input data is .SM CCITT Group 4 encoded. .TP .B \-U Assume input data is uncompressed (Group 3 or Group 4). .TP .B \-1 Assume input data is encoded with the 1-dimensional version of the .SM CCITT Group 3 Huffman encoding algorithm (default). .TP .B \-2 Assume input data is 2-dimensional version of the .SM CCITT Group 3 Huffman encoding algorithm. .TP .B \-P Assume input data is .B not EOL-aligned (default). This option has effect with Group 3 encoded input only. .TP .B \-A Assume input data is EOL-aligned. This option has effect with Group 3 encoded input only. .TP .B \-M Treat input data as having bits filled from most significant bit (\c .SM MSB\c ) to most least bit (\c .SM LSB\c ). .TP .B \-L Treat input data as having bits filled from least significant bit (\c .SM LSB\c ) to most significant bit (\c .SM MSB\c ) (default). .TP .B \-B Assume input data was encoded with black as 0 and white as 1. .TP .B \-W Assume input data was encoded with black as 1 and white as 0 (default). .TP .B \-R Specify the vertical resolution, in lines/inch, of the input images. By default input are assumed to have a vertical resolution of 196 lines/inch. If images are low resolution facsimile, a value of 98 lines/inch should be specified. .TP .B \-X Specify the width, in pixels, of the input images. By default input are assumed to have a width of 1728 pixels. .PP Options that affect the output file format are: .TP .B \-o Specify the name of the output file. .TP .B \-7 Force output to be compressed with the .SM CCITT Group 3 Huffman encoding algorithm (default). .TP .B \-8 Force output to be compressed with the .SM CCITT Group 4 Huffman encoding. .TP .B \-u Force output to be uncompressed (Group 3 or Group 4). .TP .B \-5 Force output to be encoded with the 1-dimensional version of the .SM CCITT Group 3 Huffman encoding algorithm. .TP .B \-6 Force output to be encoded with the 2-dimensional version of the .SM CCITT Group 3 Huffman encoding algorithm (default). .TP .B \-a Force the last bit of each .I "End Of Line" (\c .SM EOL\c ) code to land on a byte boundary (default). This ``zero padding'' will be reflected in the contents of the .I Group3Options tag of the resultant .SM TIFF file. This option has effect with Group 3 encoded output only. .TP .B \-p Do not EOL-align output. This option has effect with Group 3 encoded output only. .TP .B \-c Generate "classic" Group 3 TIFF format. .TP .B \-f Generate TIFF Class F (TIFF/F) format (default). .TP .B \-m Force output data to have bits filled from most significant bit (\c .SM MSB\c ) to most least bit (\c .SM LSB\c ). .TP .B \-l Force output data to have bits filled from least significant bit (\c .SM LSB\c ) to most significant bit (\c .SM MSB\c ) (default). .TP .B \-r Specify the number of rows (scanlines) in each strip of data written to the output file. By default (or when value .B 0 is specified), .I tiffcp attempts to set the rows/strip that no more than 8 kilobytes of data appear in a strip (with except of G3/G4 compression schemes). If you specify special value .B \-1 it will results in infinite number of the rows per strip. The entire image will be the one strip in that case. This is default in case of G3/G4 output compression schemes. .TP .B \-s Stretch the input image vertically by writing each input row of data twice to the output file. .TP .B \-v Force .I fax2tiff to print the number of rows of data it retrieved from the input file. .TP .B \-z Force output to be compressed with the LZW encoding. .SH DIAGNOSTICS The following warnings and errors come from the decoding routines in the library. .PP .BR "Warning, %s: Premature EOL at scanline %d (x %d).\en" . The input data had a row that was shorter than the expected width. The row is padded with white. .PP .BR "%s: Premature EOF at scanline %d (x %d).\en" . The decoder ran out of data in the middle of a scanline. The resultant row is padded with white. .PP .BR "%s: Bad code word at row %d, x %d\en" . An invalid Group 3 .I code was encountered while decoding the input file. The row number and horizontal position is given.

Each image is placed in a fixed size window that the user must position on the display (unless configured otherwise through X defaults). If the display has fewer than 24 bitplanes, or if the image does not warrant full color, then .SM RGB color values are mapped to the closest values that exist in the colormap (this is done using the .I rgbi routine found in the graphics utility library .BR \-lgutil .) .PP .I tiffgt correctly handles files with any of the following characteristics: .sp .5 .in +0.5i .ta \w'\fIPhotometricInterpretation\fP 'u .nf \fIBitsPerSample\fP 1, 2, 4, 8, 16 \fISamplesPerPixel\fP 1, 3, 4 (the 4th sample is ignored) \fIPhotometricInterpretation\fP 0 (min-is-white), 1 (min-is-black), 2 (RGB), 3 (palette), 6 (YCbCr) \fIPlanarConfiguration\fP 1 (contiguous), 2 (separate) \fIOrientation\fP 1 (top-left), 4 (bottom-left) .fi .in -0.5i .sp .5 Data may be organized as strips or tiles and may be compressed with any of the compression algorithms supported by the .IR libtiff (3) library. .PP For palette images (\c .IR PhotometricInterpretation =3), .I tiffgt inspects the colormap values and assumes either 16-bit or 8-bit values according to the maximum value. That is, if no colormap entry greater than 255 is found, .I tiffgt assumes the colormap has only 8-bit values; otherwise it assumes 16-bit values. This inspection is done to handle old images written by previous (incorrect) versions of .IR libtiff . .PP .I tiffgt can be used to display multiple images one-at-a-time. The left mouse button switches the display to the first image in the .I next file in the list of files specified on the command line. The right mouse button switches to the first image in the .I previous file in the list. The middle mouse button causes the first image in the first file specified on the command line to be displayed. In addition the following keyboard commands are recognized: .TP .B b Use a .I PhotometricInterpretation of MinIsBlack in displaying the current image. .TP .B l Use a .I FillOrder of lsb-to-msb in decoding the current image. .TP .B m Use a .I FillOrder of msb-to-lsb in decoding the current image. .TP .B c Use a colormap visual to display the current image. .TP .B r Use a true color (24-bit RGB) visual to display the current image. .TP .B w Use a .I PhotometricInterpretation of MinIsWhite in displaying the current image. .TP .B W Toggle (enable/disable) display of warning messages from the .SM TIFF library when decoding images. .TP .B E Toggle (enable/disable) display of error messages from the .SM TIFF library when decoding images. .TP .B z Reset all parameters to their default settings (\c .IR FillOrder , .IR PhotometricInterpretation , handling of warnings and errors). .TP .B PageUp Display the previous image in the current file or the last image in the previous file. .TP .B PageDown Display the next image in the current file or the first image in the next file. .TP .B Home Display the first image in the current file. .TP .B End Display the last image in the current file (unimplemented). .SH OPTIONS .TP .B \-c Force image display in a colormap window. .TP .B \-d Specify an image to display by directory number.

It can also be used to subdivide all or part of a processed image into smaller sections and export individual images or sections of images as separate files or separate images within one or more files derived from the original input image or images. .PP The available functions can be grouped broadly into three classes: .IP Those that select individual images or sections of images from the input files. The options \-N for sequences or lists of individual images in the input files, \-Z for zones, \-z for regions, \-X and \-Y for fixed sized selections, \-m for margins, \-U for units, and \-E for edge reference provide a variety of ways to specify portions of the input image. .IP Those that allow the individual images or selections to be exported to one or more output files in different groupings and control the organization of the data in the output images. The options \-P for page size grouping, \-S for subdivision into columns and rows and \-e for export mode options that produce one or more files from each input image. The options \-r, \-s, \-t, \-w control strip and tile format and sizes while \-B \-L \-c \-f modify the endian addressing scheme, the compression options, and the bit fill sequence of images as they are written. .IP Those that perform some action on each image that is selected from the input file. The options include \-R for rotate, \-I for inversion of the photometric interpretation and/or data values, and \-F to flip (mirror) the image horizontally or vertically. .PP Functions are applied to the input image(s) in the following order: cropping, fixed area extraction, zone and region extraction, inversion, mirroring, rotation. .PP Functions are applied to the output image(s) in the following order: export mode options for grouping zones, regions, or images into one or more files, .I or row and column divisions with output margins, .I or page size divisions with page orientation options. .PP Finally, strip, tile, byte order, output resolution, and compression options are applied to all output images. .PP The output file(s) may be organized and compressed using a different algorithm from the input files. By default, .I tiffcrop will copy all the understood tags in a .SM TIFF directory of an input file to the associated directory in the output file. Options can be used to force the resultant image to be written as strips or tiles of data, respectively. .PP .I Tiffcrop can be used to reorganize the storage characteristics of data in a file, and to reorganize, extract, rotate, and otherwise process the image data as specified at the same time whereas tiffcp does not alter the image data within the file. .PP Using the options for selecting individual input images and the options for exporting images and/or segments defined as zones or regions of each input image, .I tiffcrop can perform the functions of tiffcp and tiffsplit in a single pass while applying multiple operations to individual selections or images. .PP .SH "OPTIONS" .TP .B \-h Display the syntax summary for tiffcrop. .TP .B \-v Report the current version and last modification date for tiffcrop. .TP .B \-N odd|even|#,#\-#,#|last Specify one or more series or range(s) of images within each file to process. The words .B odd or .B even may be used to specify all odd or even numbered images counting from one. Note that internally, TIFF images are numbered from zero rather than one but since this convention is not obvious to most users, tiffcrop used 1 to specifiy the first image in a multipage file. The word .B last may be used in place of a number in the sequence to indicate the final image in the file without knowing how many images there are. Ranges of images may be specified with a dash and multiple sets can be indicated by joining them in a comma\-separated list. eg. use .B \-N 1,5\-7,last to process the 1st, 5th through 7th, and final image in the file. .TP .B \-E top|bottom|left|right Specify the top, bottom, left, or right edge as the reference from which to calcuate the width and length of crop regions or sequence of postions for zones. When used with the \-e option for exporting zones or regions, the reference edge determines how composite images are arranged. Using \-E left or right causes successive zones or regions to be merged horizontally whereas using \-E top or bottom causes successive zones or regions to be arranged vertically. This option has no effect on export layout when multiple zones or regions are not being exported to composite images. Edges may be abbreviated to the first letter. .TP .B \-e combined|divided|image|multiple|separate Specify the export mode for images and selections from input images. The final filename on the command line is considered to be the destination file or filename stem for automatically generated sequences of files. Modes may be abbreviated to the first letter. .IP combined All images and selections are written to a single file with multiple selections from one image combined into a single image (default) .IP divided All images and selections are written to a single file with each selection from one image written to a new image .IP image Each input image is written to a new file (numeric filename sequence) with multiple selections from the image combined into one image .IP multiple Each input image is written to a new file (numeric filename sequence) with each selection from the image written to a new image .IP separate Individual selections from each image are written to separate files .TP .B \-U in|cm|px Specify the type of units to apply to dimensions for margins and crop regions for input and output images. Inches or centimeters are converted to pixels using the resolution unit specified in the TIFF file (which defaults to inches if not specified in the IFD). .TP .B \-m #,#,#,# Specify margins to be removed from the input image. The order must be top, left, bottom, right with only commas separating the elements of the list. Margins are scaled according to the current units and removed before any other extractions are computed.. .TP .B \-X # Set the horizontal (X\-axis) dimension of a region to extract relative to the specified origin reference. If the origin is the top or bottom edge, the X axis value will be assumed to start at the left edge. .TP .B \-Y # Set the vertical (Y\-axis) dimension of a region to extract relative to the specified origin reference. If the origin is the left or right edge, the Y axis value will be assumed to start at the top. .TP .B \-Z #:#,#:# Specify zones of the image designated as position X of Y equal sized portions measured from the reference edge, eg 1:3 would be first third of the image starting from the reference edge minus any margins specified for the confining edges. Multiple zones can be specified as a comma separated list but they must reference the same edge. To extract the top quarter and the bottom third of an image you would use .B \-Z 1:4,3:3. .TP .B \-z x1,y1,x2,y2: ... :xN,yN,xN+1,yN+1 Specify a series of coordinates to define regions for processing and exporting. The coordinates represent the top left and lower right corners of each region in the current units, eg inch, cm, or pixels. Pixels are counted from one to width or height and inches or cm are calculated from image resolution data. Each colon delimited series of four values represents the horizontal and vertical offsets from the top and left edges of the image, regardless of the edge specified with the \-E option. The first and third values represent the horizontal offsets of the corner points from the left edge while the second and fourth values represent the vertical offsets from the top edge. .TP .B \-F horiz|vert Flip, ie mirror, the image or extracted region horizontally or vertically. .TP .B \-R 90|180|270 Rotate the image or extracted region 90, 180, or 270 degrees clockwise. .TP .B \\-I [black|white|data|both] Invert color space, eg dark to light for bilevel and grayscale images. This can be used to modify negative images to positive or to correct images that have the PHOTOMETRIC_INTERPRETATIN tag set incorrectly. If the value is black or white, the PHOTOMETRIC_INTERPRETATION tag is set to MinIsBlack or MinIsWhite, without altering the image data. If the argument is data or both, the data values of the image are modified. Specifying both inverts the data and the PHOTOMETRIC_INTERPRETATION tag, whereas using data inverts the data but not the PHOTOMETRIC_INTERPRETATION tag. No support for modifying the color space of color images in this release. .TP .B \-H # Set the horizontal resolution of output images to # expressed in the current units. .TP .B \-V # Set the vertical resolution of the output images to # expressed in the current units. .TP .B \-J # Set the horizontal margin of an output page size to # expressed in the current units when sectioning image into columns x rows subimages using the \-S cols:rows option. .TP .B \-K # Set the vertical margin of an output page size to # expressed in the current units when sectioning image into columns x rows submiages using the \-S cols:rows option. .TP .B \-O portrait|landscape|auto Set the output orientation of the pages or sections. Auto will use the arrangement that requires the fewest pages. This option is only meaningful in conjunction with the -P option to format an image to fit on a specific paper size. .TP .B \-P page Format the output images to fit on page size paper. Use \-P list to show the supported page sizes and dimensions. You can define a custom page size by entering the width and length of the page in the current units with the following format #.#x#.#. .TP .B \-S cols:rows Divide each image into cols across and rows down equal sections. .TP .B \-B Force output to be written with Big\-Endian byte order. This option only has an effect when the output file is created or overwritten and not when it is appended to. .TP .B \-C Suppress the use of ``strip chopping'' when reading images that have a single strip/tile of uncompressed data. .TP .B \-c Specify the compression to use for data written to the output file: .B none for no compression, .B packbits for PackBits compression, .B lzw for Lempel\-Ziv & Welch compression, .B jpeg for baseline JPEG compression. .B zip for Deflate compression, .B g3 for CCITT Group 3 (T.4) compression, and .B g4 for CCITT Group 4 (T.6) compression. By default .I tiffcrop will compress data according to the value of the .I Compression tag found in the source file. .IP The .SM CCITT Group 3 and Group 4 compression algorithms can only be used with bilevel data. .IP Group 3 compression can be specified together with several T.4\-specific options: .B 1d for 1\-dimensional encoding, .B 2d for 2\-dimensional encoding, and .B fill to force each encoded scanline to be zero\-filled so that the terminating EOL code lies on a byte boundary. Group 3\-specific options are specified by appending a ``:''\-separated list to the ``g3'' option; e.g. .B "\-c g3:2d:fill" to get 2D\-encoded data with byte\-aligned EOL codes. .IP .SM LZW compression can be specified together with a .I predictor value. A predictor value of 2 causes each scanline of the output image to undergo horizontal differencing before it is encoded; a value of 1 forces each scanline to be encoded without differencing. LZW\-specific options are specified by appending a ``:''\-separated list to the ``lzw'' option; e.g. .B "\-c lzw:2" for .SM LZW compression with horizontal differencing. .TP .B \-f Specify the bit fill order to use in writing output data. By default, .I tiffcrop will create a new file with the same fill order as the original. Specifying .B "\-f lsb2msb" will force data to be written with the FillOrder tag set to .SM LSB2MSB, while .B "\-f msb2lsb" will force data to be written with the FillOrder tag set to .SM MSB2LSB. .TP .B \-i Ignore non\-fatal read errors and continue processing of the input file. .TP .B \-l Specify the length of a tile (in pixels). .I Tiffcrop attempts to set the tile dimensions so that no more than 8 kilobytes of data appear in a tile. .TP .B \-L Force output to be written with Little\-Endian byte order. This option only has an effect when the output file is created or overwritten and not when it is appended to. .TP .B \-M Suppress the use of memory\-mapped files when reading images. .TP .B \-p Specify the planar configuration to use in writing image data that has more than one sample per pixel. By default, .I tiffcrop will create a new file with the same planar configuration as the original. Specifying .B "\-p contig" will force data to be written with multi\-sample data packed together, while .B "\-p separate" will force samples to be written in separate planes. .TP .B \-r Specify the number of rows (scanlines) in each strip of data written to the output file. By default (or when value .B 0 is specified), .I tiffcrop attempts to set the rows/strip that no more than 8 kilobytes of data appear in a strip. If you specify the special value .B \-1 it will results in infinite number of the rows per strip. The entire image will be the one strip in that case. .TP .B \-s Force the output file to be written with data organized in strips (rather than tiles). .TP .B \-t Force the output file to be written with data organized in tiles (rather than strips). .TP .B \-w Specify the width of a tile (in pixels). .I tiffcrop attempts to set the tile dimensions so that no more than 8 kilobytes of data appear in a tile. .I tiffcrop attempts to set the tile dimensions so that no more than 8 kilobytes of data appear in a tile. .TP Debug and dump facility .B \-D opt1:value1,opt2:value2,opt3:value3:opt4:value4 Display program progress and/or dump raw data to non\-TIFF files. Options include the following and must be joined as a comma separated list. The use of this option is generally limited to program debugging and development of future options. An equal sign may be substituted for the colon in option:value pairs. .IP debug:N Display limited program progress indicators where larger N increase the level of detail. .IP format:txt|raw Format any logged data as ASCII text or raw binary values. ASCII text dumps include strings of ones and zeroes representing the binary values in the image data plus identifying headers. .IP level:N Specify the level of detail presented in the dump files. This can vary from dumps of the entire input or output image data to dumps of data processed by specific functions. Current range of levels is 1 to 3. .IP input:full\-path\-to\-directory/input\-dumpname .IP output:full\-path\-to\-directory/output\-dumpname .IP When dump files are being written, each image will be written to a separate file with the name built by adding a numeric sequence value to the dumpname and an extension of .txt for ASCII dumps or .bin for binary dumps. The four debug/dump options are independent, though it makes little sense to specify a dump file without specifying a detail level. .IP Note: Tiffcrop may be compiled with -DDEVELMODE to enable additional very low level debug reporting. .SH "EXAMPLES" The following concatenates two files and writes the result using .SM LZW encoding: .RS .nf tiffcrop \-c lzw a.tif b.tif result.tif .fi .RE .PP To convert a G3 1d\-encoded .SM TIFF to a single strip of G4\-encoded data the following might be used: .RS .nf tiffcrop \-c g4 \-r 10000 g3.tif g4.tif .fi .RE (1000 is just a number that is larger than the number of rows in the source file.) To extract a selected set of images from a multi\-image TIFF file use the \-N option described above. Thus, to copy the 1st and 3rd images of image file "album.tif" to "result.tif": .RS .nf tiffcrop \-N 1,3 album.tif result.tif .fi .RE .PP Invert a bilevel image scan of a microfilmed document and crop off margins of 0.25 inches on the left and right, 0.5 inch on the top, and 0.75 inch on the bottom. From the remaining portion of the image, select the second and third quarters, ie, one half of the area left from the center to each margin. .RS tiffcrop \-U in \-m 0.5,0.25,0.75,0.25 \-E left \-Z 2:4,3:4 \-I both MicrofilmNegative.tif MicrofilmPostiveCenter.tif .fi .RE .PP Extract only the final image of a large Architectural E sized multipage TIFF file and rotate it 90 degrees clockwise while reformatting the output to fit on tabloid sized sheets with one quarter of an inch on each side: .RS tiffcrop \-N last \-R 90 \-O auto \-P tabloid \-U in \-J 0.25 \-K 0.25 \-H 300 \-V 300 Big\-PlatMap.tif BigPlatMap\-Tabloid.tif .fi .RE The output images will have a specified resolution of 300 dpi in both directions. The orientation of each page will be determined by whichever choice requires the fewest pages. To specify a specific orientation, use the portrait or landscape option. The paper size option does not resample the image. It breaks each original image into a series of smaller images that will fit on the target paper size at the specified resolution. .fi .RE .PP Extract two regions 2048 pixels wide by 2048 pixels high from each page of a multi\-page input file and write each region to a separate output file. .RS tiffcrop \-U px \-z 1,1,2048,2048:1,2049,2048,4097 \-e separate CheckScans.tiff Check .fi .RE The output file names will use the stem Check with a numeric suffix which is incremented for each region of each image, eg Check\-001.tiff, Check\-002.tiff ... Check\-NNN.tiff. To produce a unique file for each page of the input image with one new image for each region of the input image on that page, change the export option to \-e multiple. .SH "NOTES" .PP In general, bilevel, grayscale, palette and RGB(A) data with bit depths from 1 to 32 bits should work in both interleaved and separate plane formats. Unlike tiffcp, tiffcrop can read and write tiled images with bits per sample that are not a multiple of 8 in both interleaved and separate planar format. Floating point data types are supported at bit depts of 16, 24, 32 and 64 bits per sample. .PP Not all images can be converted from one compression scheme to another. Data with some photometric interpretations and/or bit depths are tied to specific compression schemes and vice-versa, e.g. Group 3/4 compression is only usable for bilevel data. JPEG compression is only usable on 8 bit per sample data (or 12 bit if .I LibTIFF was compiled with 12 bit JPEG support). Support for OJPEG compressed images is problematic at best. Since OJPEG compression is no longer supported for writing images with LibTIFF, these images will be updated to the newer JPEG compression when they are copied or processed. This may cause the image to appear color shifted or distorted after conversion. In some cases, it is possible to remove the original compression from image data using the option -cnone. .PP Tiffcrop does not currently provide options to up or downsample data to different bit depths or convert data from one photometric interpretation to another, e.g. 16 bits per sample to 8 bits per sample or RGB to grayscale. .PP Tiffcrop is very loosely derived from code in .I tiffcp with extensive modifications and additions to support the selection of input images and regions and the exporting of them to one or more output files in various groupings. The image manipulation routines are entirely new and additional ones may be added in the future. It will handle tiled images with bit depths that are not a multiple of eight that tiffcp may refuse to read. .PP .I Tiffcrop was designed to handle large files containing many moderate sized images with memory usage that is independent of the number of images in the file. In order to support compression modes that are not based on individual scanlines, e.g. JPEG, it now reads images by strip or tile rather than by indvidual scanlines. In addition to the memory required by the input and output buffers associated with .I LibTIFF one or more buffers at least as large as the largest image to be read are required. The design favors large volume document processing uses over scientific or graphical manipulation of large datasets as might be found in research or remote sensing scenarios. .SH "SEE ALSO" .BR pal2rgb (1), .BR tiffinfo (1), .BR tiffcmp (1), .BR tiffcp (1), .BR tiffmedian (1), .BR tiffsplit (1), .BR libtiff (3TIFF) .PP Libtiff library home page: .BR http://www.remotesensing.org/libtiff/ tiff-4.0.3/man/tiffinfo.10000644000212300117540000000524311244562247012043 00000000000000.\" $Id: tiffinfo.1,v 1.2 2005-11-02 11:07:19 dron Exp $ .\" .\" Copyright (c) 1988-1997 Sam Leffler .\" Copyright (c) 1991-1997 Silicon Graphics, Inc. .\" .\" Permission to use, copy, modify, distribute, and sell this software and .\" its documentation for any purpose is hereby granted without fee, provided .\" that (i) the above copyright notices and this permission notice appear in .\" all copies of the software and related documentation, and (ii) the names of .\" Sam Leffler and Silicon Graphics may not be used in any advertising or .\" publicity relating to the software without the specific, prior written .\" permission of Sam Leffler and Silicon Graphics. .\" .\" THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, .\" EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY .\" WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. .\" .\" IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR .\" ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, .\" OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, .\" WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF .\" LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE .\" OF THIS SOFTWARE. .\" .if n .po 0 .TH TIFFINFO 1 "November 2, 2005" "libtiff" .SH NAME tiffinfo \- print information about .SM TIFF files .SH SYNOPSIS .B tiffinfo [ .I options ] .I "input.tif \&..." .SH DESCRIPTION .I Tiffinfo displays information about files created according to the Tag Image File Format, Revision 6.0.

To set the value of a field the file must have been previously opened for writing with .IR TIFFOpen (3TIFF); pseudo-tags can be set whether the file was opened for reading or writing. The field is identified by .IR tag , one of the values defined in the include file .B tiff.h (see also the table below). The actual value is specified using a variable argument list, as prescribed by the .IR stdarg (3) interface (\c or, on some machines, the .IR varargs (3) interface.) .PP .IR TIFFVSetField is functionally equivalent to .IR TIFFSetField except that it takes a pointer to a variable argument list. .I TIFFVSetField is useful for writing routines that are layered on top of the functionality provided by .IR TIFFSetField . .PP The tags understood by .IR libtiff , the number of parameter values, and the expected types for the parameter values are shown below. The data types are: .I char* is null-terminated string and corresponds to the .SM ASCII data type; .I uint16 is an unsigned 16-bit value; .I uint32 is an unsigned 32-bit value; .I uint16* is an array of unsigned 16-bit values. .I void* is an array of data values of unspecified type.

The raster is assumed to be an array of width times length 32-bit entries, where width is the width of a tile (TIFFTAG_TILEWIDTH) and length is the height of a tile (TIFFTAG_TILELENGTH). .PP The .IR x and .IR y values are the offsets from the top left corner to the top left corner of the tile to be read. They must be an exact multiple of the tile width and length. .PP Note that the raster is assume to be organized such that the pixel at location (\fIx\fP,\fIy\fP) is \fIraster\fP[\fIy\fP*\fIwidth\fP+\fIx\fP]; with the raster origin in the .I lower-left hand corner of the tile. That is bottom to top organization. Edge tiles which partly fall off the image will be filled out with appropriate zeroed areas. .PP Raster pixels are 8-bit packed red, green, blue, alpha samples. The macros .IR TIFFGetR , .IR TIFFGetG , .IR TIFFGetB , and .I TIFFGetA should be used to access individual samples.

It's main advantage over the similar .IR TIFFReadRGBAImage() function is that for large images a single buffer capable of holding the whole image doesn't need to be allocated, only enough for one tile.

The .I sample parameter is used only if data are organized in separate planes (\c .IR PlanarConfiguration =2). The data are assumed to be uncompressed and in the native bit- and byte-order of the host machine. The data written to the file is compressed according to the compression scheme of the current .SM TIFF directory (see further below). If the current scanline is past the end of the current subfile, the .I ImageLength field is automatically increased to include the scanline (except for .IR PlanarConfiguration =2, where the .I ImageLength cannot be changed once the first data are written). If the .I ImageLength is increased, the .I StripOffsets and .I StripByteCounts fields are similarly enlarged to reflect data written past the previous end of image. .SH NOTES The library writes encoded data using the native machine byte order. Correctly implemented .SM TIFF readers are expected to do any necessary byte-swapping to correctly process image data with BitsPerSample greater than 8. The library attempts to hide bit-ordering differences between the image and the native machine by converting data from the native machine order. .PP In C++ the .I sample parameter defaults to 0. .PP Once data are written to a file for the current directory, the values of certain tags may not be altered; see .IR TIFFSetField (3TIFF) for more information. .PP It is not possible to write scanlines to a file that uses a tiled organization. The routine .IR TIFFIsTiled can be used to determine if the file is organized as tiles or strips. .SH "RETURN VALUES" .IR TIFFWriteScanline returns \-1 if it immediately detects an error and 1 for a successful write. .SH DIAGNOSTICS All error messages are directed to the .IR TIFFError (3TIFF) routine. .PP .BR "%s: File not open for writing . The file was opened for reading, not writing. .PP .BR "Can not write scanlines to a tiled image" . An attempt was made to write a scanline to a tiled image. The image is assumed to be organized in tiles because the .I TileWidth and .I TileLength tags have been set with .IR TIFFSetField (3TIFF). .PP .BR "Compression algorithm does not support random access" . Data was written in a non-sequential order to a file that uses a compression algorithm and that has .I RowsPerStrip greater than one. That is, data in the image is to be stored in a compressed form, and with multiple rows packed into a strip. In this case, the library does not support random access to the data. The data should either be written as entire strips, sequentially by rows, or the value of .I RowsPerStrip should be set to one. .PP \fB%s: Must set "ImageWidth" before writing data\fP. The image's width has not be set before the first write. See .BR TIFFSetField (3TIFF) for information on how to do this. .PP \fB%s: Must set "PlanarConfiguration" before writing data\fP. The organization of data has not be defined before the first write. See .BR TIFFSetField (3TIFF) for information on how to do this. .PP \fBCan not change "ImageLength" when using separate planes\fP. Separate image planes are being used (\c .IR PlanarConfiguration =2), but the number of rows has not been specified before the first write. The library supports the dynamic growth of an image only when data are organized in a contiguous manner (\c .IR PlanarConfiguration =1). .PP .BR "%d: Sample out of range, max %d" . The .I sample parameter was greater than the value of the SamplesPerPixel tag. .PP .BR "%s: No space for strip arrays . There was not enough space for the arrays that hold strip offsets and byte counts. .SH BUGS Writing subsampled YCbCR data does not work correctly because, for .IR PlanarConfiguration =2 the size of a scanline is not calculated on a per-sample basis, and for .IR PlanarConfiguration =1 the library does not pack the block-interleaved samples. .SH "SEE ALSO" .BR TIFFOpen (3TIFF), .BR TIFFWriteEncodedStrip (3TIFF), .BR TIFFWriteRawStrip (3TIFF), .BR libtiff (3TIFF) .PP Libtiff library home page: .BR http://www.remotesensing.org/libtiff/ tiff-4.0.3/man/tiff2bw.10000644000212300117540000000537211244562247011605 00000000000000.\" $Id: tiff2bw.1,v 1.3 2006-04-20 12:17:19 dron Exp $ .\" .\" Copyright (c) 1988-1997 Sam Leffler .\" Copyright (c) 1991-1997 Silicon Graphics, Inc. .\" .\" Permission to use, copy, modify, distribute, and sell this software and .\" its documentation for any purpose is hereby granted without fee, provided .\" that (i) the above copyright notices and this permission notice appear in .\" all copies of the software and related documentation, and (ii) the names of .\" Sam Leffler and Silicon Graphics may not be used in any advertising or .\" publicity relating to the software without the specific, prior written .\" permission of Sam Leffler and Silicon Graphics. .\" .\" THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, .\" EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY .\" WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. .\" .\" IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR .\" ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, .\" OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, .\" WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF .\" LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE .\" OF THIS SOFTWARE. .\" .if n .po 0 .TH TIFF2BW 1 "November 2, 2005" "libtiff" .SH NAME tiff2bw \- convert a color .SM TIFF image to greyscale .SH SYNOPSIS .B tiff2bw [ .I options ] .I input.tif .I output.tif .SH DESCRIPTION .I Tiff2bw converts an .SM RGB or Palette color .SM TIFF image to a greyscale image by combining percentages of the red, green, and blue channels.

The raster is assumed to be an array of .I width times .I height 32-bit entries, where .I width must be less than or equal to the width of the image (\c .I height may be any non-zero size). If the raster dimensions are smaller than the image, the image data is cropped to the raster bounds.

Alternate page dimensions can be specified in inches with the .B \-W and .B \-H options. .PP By default .I fax2ps generates \*(Ps for all pages in the file. The .B \-p option can be used to select one or more pages from a multi-page document. .PP .I fax2ps generates a compressed form of \*(Ps that is optimized for sending pages of text to a \*(Ps printer attached to a host through a low-speed link (such as a serial line). Each output page is filled with white and then only the black areas are drawn. The \*(Ps specification of the black drawing operations is optimized by using a special font that encodes the move-draw operations required to fill the black regions on the page. This compression scheme typically results in a substantially reduced \*(Ps description, relative to the straightforward imaging of the page with a \*(Ps .I image operator. This algorithm can, however, be ineffective for continuous-tone and white-on-black images. For these images, it sometimes is more efficient to send the raster bitmap image directly; see .BR tiff2ps (1). .SH OPTIONS .TP 10 .BI \-p " number" Print only the indicated page. Multiple pages may be printed by specifying this option more than once. .TP 10 .BI \-x " resolution" Use .I resolution as the horizontal resolution, in dots/inch, of the image data. By default this value is taken from the file. .TP 10 .BI \-y " resolution" Use .I resolution as the vertical resolution, in lines/inch, of the image data. By default this value is taken from the file. .TP 10 .B \-S Scale each page of image data to fill the output page dimensions. By default images are presented according to the dimension information recorded in the .SM TIFF file. .TP 10 .BI \-W " width" Use .I width as the width, in inches, of the output page. .TP 10 .BI \-H " height" Use .I height as the height, in inches, of the output page. .SH DIAGNOSTICS Some messages about malformed .SM TIFF images come from the .SM TIFF library. .PP Various messages about badly formatted facsimile images may be generated due to transmission errors in received facsimile. .I fax2ps attempts to recover from such data errors by resynchronizing decoding at the end of the current scanline. This can result in long horizontal black lines in the resultant \*(Ps image. .SH NOTES If the destination printer supports \*(Ps Level II then it is always faster to just send the encoded bitmap generated by the .BR tiff2ps (1) program. .SH BUGS .I fax2ps should probably figure out when it is doing a poor job of compressing the output and just generate \*(Ps to image the bitmap raster instead. .SH "SEE ALSO" .BR tiff2ps (1), .BR libtiff (3) .PP Libtiff library home page: .BR http://www.remotesensing.org/libtiff/ tiff-4.0.3/man/tiffsv.10000644000212300117540000001005711244562247011537 00000000000000.\" $Id: tiffsv.1,v 1.3 2005-11-02 11:07:19 dron Exp $ .\" .\" Copyright (c) 1988-1997 Sam Leffler .\" Copyright (c) 1991-1997 Silicon Graphics, Inc. .\" .\" Permission to use, copy, modify, distribute, and sell this software and .\" its documentation for any purpose is hereby granted without fee, provided .\" that (i) the above copyright notices and this permission notice appear in .\" all copies of the software and related documentation, and (ii) the names of .\" Sam Leffler and Silicon Graphics may not be used in any advertising or .\" publicity relating to the software without the specific, prior written .\" permission of Sam Leffler and Silicon Graphics. .\" .\" THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, .\" EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY .\" WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. .\" .\" IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR .\" ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, .\" OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, .\" WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF .\" LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE .\" OF THIS SOFTWARE. .\" .if n .po 0 .TH TIFFSV 1 "September 20, 2005" "libtiff" .SH NAME tiffsv \- save an image from the framebuffer in a .SM TIFF file (Silicon Graphics version) .SH SYNOPSIS .B tiffsv [ .I options ] .I output.tif [ .I "x1 x2 y1 y2" ] .SH DESCRIPTION .I tiffsv saves all or part of the framebuffer in a file using the Tag Image File Format, Revision 6.0. By default, the image is saved with data samples packed (\c .IR PlanarConfiguration =1), compressed with the Lempel-Ziv & Welch algorithm (\c .IR Compression =5), and with each strip no more than 8 kilobytes. These characteristics can be overridden, or explicitly specified with the options described below. .SH OPTIONS .TP .B \-b Save the image as a greyscale image as if it were processed by .IR tiff2bw (1). This option is included for compatibility with the standard .IR scrsave (6D) program. .TP .B \-c Specify the compression to use for data written to the output file: .B none for no compression, .B packbits for PackBits compression, .B jpeg for baseline JPEG compression, .B zip for Deflate compression, and .B lzw for Lempel-Ziv & Welch compression (default). .IP .SM LZW compression can be specified together with a .I predictor value. A predictor value of 2 causes each scanline of the output image to undergo horizontal differencing before it is encoded; a value of 1 forces each scanline to be encoded without differencing. LZW-specific options are specified by appending a ``:''-separated list to the ``lzw'' option; e.g. .B "\-c lzw:2" for .SM LZW compression with horizontal differencing. .TP .B \-p Specify the planar configuration to use in writing image data. By default, .I tiffsv will create a new file with the data samples packed contiguously. Specifying .B "\-p contig" will force data to be written with multi-sample data packed together, while .B "\-p separate" will force samples to be written in separate planes. .TP .B \-r Specify the number of rows (scanlines) in each strip of data written to the output file. By default, .I tiffsv attempts to set the rows/strip that no more than 8 kilobytes of data appear in a strip. .SH NOTE Except for the use of .SM TIFF, this program is equivalent to the standard .I scrsave program. This means, for example, that you can use it in conjunction with the standard .IR icut program simply by creating a link called .IR scrsave , or by creating a shell script called .I scrsave that invokes .I tiffgt with the appropriate options. .SH BUGS If data are saved compressed and in separate planes, then the rows in each strip is silently set to one to avoid limitations in the .BR libtiff (3TIFF) library. .SH "SEE ALSO" .BR scrsave (6D) .BR pal2rgb (1), .BR tiffdump (1), .BR tiffgt (1), .BR tiffinfo (1), .BR tiffcp (1), .BR tiffmedian (1), .BR libtiff (3TIFF) .PP Libtiff library home page: .BR http://www.remotesensing.org/libtiff/ tiff-4.0.3/man/TIFFFieldTag.3tiff0000644000212300117540000000373312005255232013231 00000000000000.\" $Id: TIFFFieldTag.3tiff,v 1.1 2012-07-29 15:45:30 tgl Exp $ .\" .\" Copyright (c) 2012, Tom Lane .\" .\" Permission to use, copy, modify, distribute, and sell this software and .\" its documentation for any purpose is hereby granted without fee, provided .\" that (i) the above copyright notices and this permission notice appear in .\" all copies of the software and related documentation, and (ii) the names of .\" Sam Leffler and Silicon Graphics may not be used in any advertising or .\" publicity relating to the software without the specific, prior written .\" permission of Sam Leffler and Silicon Graphics. .\" .\" THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, .\" EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY .\" WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. .\" .\" IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR .\" ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, .\" OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, .\" WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF .\" LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE .\" OF THIS SOFTWARE. .\" .if n .po 0 .TH TIFFFieldTag 3TIFF "July 26, 2012" "libtiff" .SH NAME TIFFFieldTag \- Get TIFF field tag value from field information .SH SYNOPSIS .B "#include " .sp .BI "uint32 TIFFFieldTag(const TIFFField* " fip ")" .SH DESCRIPTION .BR TIFFFieldTag returns the numeric tag value for a TIFF field.

By default .I tiffdither will compress data according to the value of the .I Compression tag found in the source file. .IP The .SM CCITT Group 3 and Group 4 compression algorithms can only be used with bilevel data. .IP Group 3 compression can be specified together with several T.4-specific options: .B 1d for 1-dimensional encoding, .B 2d for 2-dimensional encoding, and .B fill to force each encoded scanline to be zero-filled so that the terminating EOL code lies on a byte boundary. Group 3-specific options are specified by appending a ``:''-separated list to the ``g3'' option; e.g. .B "\-c g3:2d:fill" to get 2D-encoded data with byte-aligned EOL codes. .IP .SM LZW compression can be specified together with a .I predictor value. A predictor value of 2 causes each scanline of the output image to undergo horizontal differencing before it is encoded; a value of 1 forces each scanline to be encoded without differencing. LZW-specific options are specified by appending a ``:''-separated list to the ``lzw'' option; e.g. .B "\-c lzw:2" for .SM LZW compression with horizontal differencing. .TP .B \-f Specify the bit fill order to use in writing output data. By default, .I tiffdither will create a new file with the same fill order as the original. Specifying .B "\-f lsb2msb" will force data to be written with the .I Fill\%Order tag set to .SM LSB2MSB , while .B "\-f msb2lsb" will force data to be written with the .I Fill\%Order tag set to .SM MSB2LSB . .TP .B \-t Set the threshold value for dithering.

The data are returned decompressed and, in the native byte- and bit-ordering, but are otherwise packed (see further below). The buffer must be large enough to hold an entire scanline of data. Applications should call the routine .IR TIFFScanlineSize to find out the size (in bytes) of a scanline buffer. The .I row parameter is always used by .IR TIFFReadScanline ; the .I sample parameter is used only if data are organized in separate planes (\c .IR PlanarConfiguration =2). .SH NOTES The library attempts to hide bit- and byte-ordering differences between the image and the native machine by converting data to the native machine order. Bit reversal is done if the .I FillOrder tag is opposite to the native machine bit order. 16- and 32-bit samples are automatically byte-swapped if the file was written with a byte order opposite to the native machine byte order, .PP In C++ the .I sample parameter defaults to 0. .SH "RETURN VALUES" .IR TIFFReadScanline returns \-1 if it detects an error; otherwise 1 is returned. .SH DIAGNOSTICS All error messages are directed to the .IR TIFFError (3TIFF) routine. .PP .BR "Compression algorithm does not support random access" . Data was requested in a non-sequential order from a file that uses a compression algorithm and that has .I RowsPerStrip greater than one. That is, data in the image is stored in a compressed form, and with multiple rows packed into a strip. In this case, the library does not support random access to the data. The data should either be accessed sequentially, or the file should be converted so that each strip is made up of one row of data. .SH BUGS Reading subsampled YCbCR data does not work correctly because, for .IR PlanarConfiguration =2 the size of a scanline is not calculated on a per-sample basis, and for .IR PlanarConfiguration =1 the library does not unpack the block-interleaved samples; use the strip- and tile-based interfaces to read these formats. .SH "SEE ALSO" .BR TIFFOpen (3TIFF), .BR TIFFReadEncodedStrip (3TIFF), .BR TIFFReadRawStrip (3TIFF), .BR libtiff (3TIFF) .PP Libtiff library home page: .BR http://www.remotesensing.org/libtiff/ tiff-4.0.3/man/TIFFFieldPassCount.3tiff0000644000212300117540000000440012005255231014424 00000000000000.\" $Id: TIFFFieldPassCount.3tiff,v 1.1 2012-07-29 15:45:29 tgl Exp $ .\" .\" Copyright (c) 2012, Tom Lane .\" .\" Permission to use, copy, modify, distribute, and sell this software and .\" its documentation for any purpose is hereby granted without fee, provided .\" that (i) the above copyright notices and this permission notice appear in .\" all copies of the software and related documentation, and (ii) the names of .\" Sam Leffler and Silicon Graphics may not be used in any advertising or .\" publicity relating to the software without the specific, prior written .\" permission of Sam Leffler and Silicon Graphics. .\" .\" THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, .\" EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY .\" WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. .\" .\" IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR .\" ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, .\" OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, .\" WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF .\" LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE .\" OF THIS SOFTWARE. .\" .if n .po 0 .TH TIFFFieldPassCount 3TIFF "July 26, 2012" "libtiff" .SH NAME TIFFFieldPassCount \- Get whether to pass a count to TIFFGet/SetField .SH SYNOPSIS .B "#include " .sp .BI "int TIFFFieldPassCount(const TIFFField* " fip ")" .SH DESCRIPTION .BR TIFFFieldPassCount returns true (nonzero) if .BR TIFFGetField and .BR TIFFSetField expect a .I count value to be passed before the actual data pointer. .P .I fip is a field information pointer previously returned by .BR TIFFFindField , .BR TIFFFieldWithTag , or .BR TIFFFieldWithName . .P When a .I count is required, it will be of type .BR uint32 when .BR TIFFFieldReadCount reports .BR TIFF_VARIABLE2 , and of type .BR uint16 otherwise.

Because the output file may be compressed using a different algorithm than the input files, .I tiffcp is most often used to convert between different compression schemes. .PP By default, .I tiffcp will copy all the understood tags in a .SM TIFF directory of an input file to the associated directory in the output file. .PP .I tiffcp can be used to reorganize the storage characteristics of data in a file, but it is explicitly intended to not alter or convert the image data content in any way. .SH OPTIONS .TP .BI \-b " image" subtract the following monochrome image from all others processed. This can be used to remove a noise bias from a set of images. This bias image is typically an image of noise the camera saw with its shutter closed. .TP .B \-B Force output to be written with Big-Endian byte order. This option only has an effect when the output file is created or overwritten and not when it is appended to. .TP .B \-C Suppress the use of ``strip chopping'' when reading images that have a single strip/tile of uncompressed data. .TP .B \-c Specify the compression to use for data written to the output file: .B none for no compression, .B packbits for PackBits compression, .B lzw for Lempel-Ziv & Welch compression, .B zip for Deflate compression, .B lzma for LZMA2 compression, .B jpeg for baseline JPEG compression, .B g3 for CCITT Group 3 (T.4) compression, and .B g4 for CCITT Group 4 (T.6) compression. By default .I tiffcp will compress data according to the value of the .I Compression tag found in the source file. .IP The .SM CCITT Group 3 and Group 4 compression algorithms can only be used with bilevel data. .IP Group 3 compression can be specified together with several T.4-specific options: .B 1d for 1-dimensional encoding, .B 2d for 2-dimensional encoding, and .B fill to force each encoded scanline to be zero-filled so that the terminating EOL code lies on a byte boundary. Group 3-specific options are specified by appending a ``:''-separated list to the ``g3'' option; e.g. .B "\-c g3:2d:fill" to get 2D-encoded data with byte-aligned EOL codes. .IP .SM LZW, Deflate and .SM LZMA2 compression can be specified together with a .I predictor value. A predictor value of 2 causes each scanline of the output image to undergo horizontal differencing before it is encoded; a value of 1 forces each scanline to be encoded without differencing. A value 3 is for floating point predictor which you can use if the encoded data are in floating point format. LZW-specific options are specified by appending a ``:''-separated list to the ``lzw'' option; e.g. .B "\-c lzw:2" for .SM LZW compression with horizontal differencing. .IP .SM Deflate and .SM LZMA2 encoders support various compression levels (or encoder presets) set as character ``p'' and a preset number. ``p1'' is the fastest one with the worst compression ratio and ``p9'' is the slowest but with the best possible ratio; e.g. .B "\-c zip:3:p9" for .SM Deflate encoding with maximum compression level and floating point predictor. .TP .B \-f Specify the bit fill order to use in writing output data. By default, .I tiffcp will create a new file with the same fill order as the original. Specifying .B "\-f lsb2msb" will force data to be written with the FillOrder tag set to .SM LSB2MSB, while .B "\-f msb2lsb" will force data to be written with the FillOrder tag set to .SM MSB2LSB. .TP .B \-i Ignore non-fatal read errors and continue processing of the input file. .TP .B \-l Specify the length of a tile (in pixels). .I tiffcp attempts to set the tile dimensions so that no more than 8 kilobytes of data appear in a tile. .TP .B \-L Force output to be written with Little-Endian byte order. This option only has an effect when the output file is created or overwritten and not when it is appended to. .TP .B \-M Suppress the use of memory-mapped files when reading images. .TP .B \-p Specify the planar configuration to use in writing image data that has one 8-bit sample per pixel. By default, .I tiffcp will create a new file with the same planar configuration as the original. Specifying .B "\-p contig" will force data to be written with multi-sample data packed together, while .B "\-p separate" will force samples to be written in separate planes. .TP .B \-r Specify the number of rows (scanlines) in each strip of data written to the output file. By default (or when value .B 0 is specified), .I tiffcp attempts to set the rows/strip that no more than 8 kilobytes of data appear in a strip. If you specify special value .B \-1 it will results in infinite number of the rows per strip. The entire image will be the one strip in that case. .TP .B \-s Force the output file to be written with data organized in strips (rather than tiles). .TP .B \-t Force the output file to be written with data organized in tiles (rather than strips). options can be used to force the resultant image to be written as strips or tiles of data, respectively. .TP .B \-w Specify the width of a tile (in pixels). .I tiffcp attempts to set the tile dimensions so that no more than 8 kilobytes of data appear in a tile. .I tiffcp attempts to set the tile dimensions so that no more than 8 kilobytes of data appear in a tile. .TP .B \-x Force the output file to be written with PAGENUMBER value in sequence. .TP .BI \-,= character substitute .I character for `,' in parsing image directory indices in files. This is necessary if filenames contain commas. Note that .B \-,= with whitespace immediately following will disable the special meaning of the `,' entirely. See examples. .SH EXAMPLES The following concatenates two files and writes the result using .SM LZW encoding: .RS .nf tiffcp \-c lzw a.tif b.tif result.tif .fi .RE .PP To convert a G3 1d-encoded .SM TIFF to a single strip of G4-encoded data the following might be used: .RS .nf tiffcp \-c g4 \-r 10000 g3.tif g4.tif .fi .RE (1000 is just a number that is larger than the number of rows in the source file.) To extract a selected set of images from a multi-image TIFF file, the file name may be immediately followed by a `,' separated list of image directory indices.

By default, output data are compressed in strips with the number of rows in each strip selected so that the size of a strip is never more than 8 kilobytes; the .B \-r option can be used to explicitly set the number of rows per strip. .SH OPTIONS .TP .B \-c Specify a compression scheme to use when writing image data: .B "\-c none" for no compression, .B "\-c packbits" for the PackBits compression algorithm (the default), .B "\-c jpeg" for the JPEG compression algorithm, .B "\-c zip" for the deflate compression algorithm, and .B "\-c lzw" for Lempel-Ziv & Welch. .TP .B \-h Set the horizontal sampling dimension to one of: 1, 2 (default), or 4. .TP .B \-r Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approximately 8 kilobytes. .TP .B \-v Set the vertical sampling dimension to one of: 1, 2 (default), or 4. .SH "SEE ALSO" .BR tiffinfo (1), .BR tiffcp (1), .BR libtiff (3) .PP Libtiff library home page: .BR http://www.remotesensing.org/libtiff tiff-4.0.3/man/TIFFquery.3tiff0000644000212300117540000001036711244562247012733 00000000000000.\" $Id: TIFFquery.3tiff,v 1.1 2004-11-11 14:39:16 dron Exp $ .\" .\" Copyright (c) 1988-1997 Sam Leffler .\" Copyright (c) 1991-1997 Silicon Graphics, Inc. .\" .\" Permission to use, copy, modify, distribute, and sell this software and .\" its documentation for any purpose is hereby granted without fee, provided .\" that (i) the above copyright notices and this permission notice appear in .\" all copies of the software and related documentation, and (ii) the names of .\" Sam Leffler and Silicon Graphics may not be used in any advertising or .\" publicity relating to the software without the specific, prior written .\" permission of Sam Leffler and Silicon Graphics. .\" .\" THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, .\" EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY .\" WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. .\" .\" IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR .\" ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, .\" OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, .\" WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF .\" LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE .\" OF THIS SOFTWARE. .\" .if n .po 0 .TH QUERY 3TIFF "October 29, 2004" "libtiff" .SH NAME TIFFCurrentRow, TIFFCurrentStrip, TIFFCurrentTile, TIFFCurrentDirectory, TIFFLastDirectory, TIFFFileno, TIFFFileName, TIFFGetMode, TIFFIsTiled, TIFFIsByteSwapped, TIFFIsUpSampled, TIFFIsMSB2LSB, TIFFGetVersion \- query routines .SH SYNOPSIS .B "#include " .sp .BI "uint32 TIFFCurrentRow(TIFF* " tif ")" .br .BI "tstrip_t TIFFCurrentStrip(TIFF* " tif ")" .br .BI "ttile_t TIFFCurrentTile(TIFF* " tif ")" .br .BI "tdir_t TIFFCurrentDirectory(TIFF* " tif ")" .br .BI "int TIFFLastDirectory(TIFF* " tif ")" .br .BI "int TIFFFileno(TIFF* " tif ")" .br .BI "char* TIFFFileName(TIFF* " tif ")" .br .BI "int TIFFGetMode(TIFF* " tif ")" .br .BI "int TIFFIsTiled(TIFF* " tif ")" .br .BI "int TIFFIsByteSwapped(TIFF* " tif ")" .br .BI "int TIFFIsUpSampled(TIFF* " tif ")" .br .BI "int TIFFIsMSB2LSB(TIFF* " tif ")" .br .BI "const char* TIFFGetVersion(void)" .SH DESCRIPTION The following routines return status information about an open .SM TIFF file. .PP .IR TIFFCurrentDirectory returns the index of the current directory (directories are numbered starting at 0). This number is suitable for use with the .IR TIFFSetDirectory routine. .PP .IR TIFFLastDirectory returns a non-zero value if the current directory is the last directory in the file; otherwise zero is returned. .PP .IR TIFFCurrentRow , .IR TIFFCurrentStrip , and .IR TIFFCurrentTile , return the current row, strip, and tile, respectively, that is being read or written. These values are updated each time a read or write is done. .PP .IR TIFFFileno returns the underlying file descriptor used to access the .SM TIFF image in the filesystem. .PP .IR TIFFFileName returns the pathname argument passed to .IR TIFFOpen or .IR TIFFFdOpen . .PP .IR TIFFGetMode returns the mode with which the underlying file was opened. On .SM UNIX systems, this is the value passed to the .IR open (2) system call. .PP .IR TIFFIsTiled returns a non-zero value if the image data has a tiled organization. Zero is returned if the image data is organized in strips. .PP .IR TIFFIsByteSwapped returns a non-zero value if the image data was in a different byte-order than the host machine.

Note that TIFFReadTile(), TIFFReadStrip() and TIFFReadScanline() functions already normally perform byte swapping to local host order if needed. .PP .I TIFFIsUpSampled returns a non-zero value if image data returned through the read interface routines is being up-sampled. This can be useful to applications that want to calculate I/O buffer sizes to reflect this usage (though the usual strip and tile size routines already do this). .PP .I TIFFIsMSB2LSB returns a non-zero value if the image data is being returned with bit 0 as the most significant bit. .PP .IR TIFFGetVersion returns an .SM ASCII string that has a version stamp for the .SM TIFF library software. .SH DIAGNOSTICS None. .SH "SEE ALSO" .IR libtiff (3TIFF), .IR TIFFOpen (3TIFF), .IR TIFFFdOpen (3TIFF) tiff-4.0.3/man/TIFFOpen.3tiff0000644000212300117540000002263111244562247012464 00000000000000.\" $Id: TIFFOpen.3tiff,v 1.2 2005-07-01 12:36:22 dron Exp $ .\" .\" Copyright (c) 1988-1997 Sam Leffler .\" Copyright (c) 1991-1997 Silicon Graphics, Inc. .\" .\" Permission to use, copy, modify, distribute, and sell this software and .\" its documentation for any purpose is hereby granted without fee, provided .\" that (i) the above copyright notices and this permission notice appear in .\" all copies of the software and related documentation, and (ii) the names of .\" Sam Leffler and Silicon Graphics may not be used in any advertising or .\" publicity relating to the software without the specific, prior written .\" permission of Sam Leffler and Silicon Graphics. .\" .\" THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, .\" EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY .\" WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. .\" .\" IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR .\" ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, .\" OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, .\" WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF .\" LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE .\" OF THIS SOFTWARE. .\" .if n .po 0 .TH TIFFOpen 3TIFF "July 1, 2005" "libtiff" .SH NAME TIFFOpen, TIFFFdOpen, TIFFClientOpen \- open a .SM TIFF file for reading or writing .SH SYNOPSIS .B "#include " .sp .BI "TIFF* TIFFOpen(const char *" filename ", const char *" mode ")" .br .BI "TIFF* TIFFFdOpen(const int " fd ", const char *" filename ", const char *" mode ")" .sp .B "typedef tsize_t (*TIFFReadWriteProc)(thandle_t, tdata_t, tsize_t);" .br .B "typedef toff_t (*TIFFSeekProc)(thandle_t, toff_t, int);" .br .B "typedef int (*TIFFCloseProc)(thandle_t);" .br .B "typedef toff_t (*TIFFSizeProc)(thandle_t);" .br .B "typedef int (*TIFFMapFileProc)(thandle_t, tdata_t*, toff_t*);" .br .B "typedef void (*TIFFUnmapFileProc)(thandle_t, tdata_t, toff_t);" .sp .BI "TIFF* TIFFClientOpen(const char *" filename ", const char *" mode ", thandle_t " clientdata ", TIFFReadWriteProc " readproc ", TIFFReadWriteProc " writeproc ", TIFFSeekProc " seekproc ", TIFFCloseProc " closeproc ", TIFFSizeProc " sizeproc ", TIFFMapFileProc " mapproc ", TIFFUnmapFileProc " unmapproc ")" .SH DESCRIPTION .IR TIFFOpen opens a .SM TIFF file whose name is .I filename and returns a handle to be used in subsequent calls to routines in .IR libtiff . If the open operation fails, then zero is returned. The .I mode parameter specifies if the file is to be opened for reading (``r''), writing (``w''), or appending (``a'') and, optionally, whether to override certain default aspects of library operation (see below). When a file is opened for appending, existing data will not be touched; instead new data will be written as additional subfiles. If an existing file is opened for writing, all previous data is overwritten. .PP If a file is opened for reading, the first .SM TIFF directory in the file is automatically read (also see .IR TIFFSetDirectory (3TIFF) for reading directories other than the first). If a file is opened for writing or appending, a default directory is automatically created for writing subsequent data. This directory has all the default values specified in .SM TIFF Revision 6.0: .IR BitsPerSample =1, .IR ThreshHolding "=bilevel art scan," .IR FillOrder =1 (most significant bit of each data byte is filled first), .IR Orientation =1 (the 0th row represents the visual top of the image, and the 0th column represents the visual left hand side), .IR SamplesPerPixel =1, .IR RowsPerStrip =infinity, .IR ResolutionUnit =2 (inches), and .IR Compression =1 (no compression). To alter these values, or to define values for additional fields, .IR TIFFSetField (3TIFF) must be used. .PP .IR TIFFFdOpen is like .IR TIFFOpen except that it opens a .SM TIFF file given an open file descriptor .IR fd . The file's name and mode must reflect that of the open descriptor. The object associated with the file descriptor .BR "must support random access" . .PP .IR TIFFClientOpen is like .IR TIFFOpen except that the caller supplies a collection of functions that the library will use to do \s-1UNIX\s+1-like I/O operations. The .I readproc and .I writeproc are called to read and write data at the current file position. .I seekproc is called to change the current file position a la .IR lseek (2). .I closeproc is invoked to release any resources associated with an open file. .I sizeproc is invoked to obtain the size in bytes of a file. .I mapproc and .I unmapproc are called to map and unmap a file's contents in memory; c.f. .IR mmap (2) and .IR munmap (2). The .I clientdata parameter is an opaque ``handle'' passed to the client-specified routines passed as parameters to .IR TIFFClientOpen . .SH OPTIONS The open mode parameter can include the following flags in addition to the ``r'', ``w'', and ``a'' flags. Note however that option flags must follow the read-write-append specification. .TP .B l When creating a new file force information be written with Little-Endian byte order (but see below). By default the library will create new files using the native .SM CPU byte order. .TP .B b When creating a new file force information be written with Big-Endian byte order (but see below). By default the library will create new files using the native .SM CPU byte order. .TP .B L Force image data that is read or written to be treated with bits filled from Least Significant Bit (\s-1LSB\s+1) to Most Significant Bit (\s-1MSB\s+1). Note that this is the opposite to the way the library has worked from its inception. .TP .B B Force image data that is read or written to be treated with bits filled from Most Significant Bit (\s-1MSB\s+1) to Least Significant Bit (\s-1LSB\s+1); this is the default. .TP .B H Force image data that is read or written to be treated with bits filled in the same order as the native .SM CPU. .TP .B M Enable the use of memory-mapped files for images opened read-only. If the underlying system does not support memory-mapped files or if the specific image being opened cannot be memory-mapped then the library will fallback to using the normal system interface for reading information. By default the library will attempt to use memory-mapped files. .TP .B m Disable the use of memory-mapped files. .TP .B C Enable the use of ``strip chopping'' when reading images that are comprised of a single strip or tile of uncompressed data. Strip chopping is a mechanism by which the library will automatically convert the single-strip image to multiple strips, each of which has about 8 Kilobytes of data. This facility can be useful in reducing the amount of memory used to read an image because the library normally reads each strip in its entirety. Strip chopping does however alter the apparent contents of the image because when an image is divided into multiple strips it looks as though the underlying file contains multiple separate strips. Finally, note that default handling of strip chopping is a compile-time configuration parameter. The default behaviour, for backwards compatibility, is to enable strip chopping. .TP .B c Disable the use of strip chopping when reading images. .TP .B h Read TIFF header only, do not load the first image directory. That could be useful in case of the broken first directory. We can open the file and proceed to the other directories. .SH "BYTE ORDER" The .SM TIFF specification (\fBall versions\fP) states that compliant readers .IR "must be capable of reading images written in either byte order" . Nonetheless some software that claims to support the reading of .SM TIFF images is incapable of reading images in anything but the native .SM CPU byte order on which the software was written. (Especially notorious are applications written to run on Intel-based machines.) By default the library will create new files with the native byte-order of the .SM CPU on which the application is run. This ensures optimal performance and is portable to any application that conforms to the TIFF specification. To force the library to use a specific byte-order when creating a new file the ``b'' and ``l'' option flags may be included in the call to open a file; for example, ``wb'' or ``wl''. .SH "RETURN VALUES" Upon successful completion .IR TIFFOpen , .IR TIFFFdOpen , and .IR TIFFClientOpen return a .SM TIFF pointer. Otherwise, NULL is returned. .SH DIAGNOSTICS All error messages are directed to the .IR TIFFError (3TIFF) routine. Likewise, warning messages are directed to the .IR TIFFWarning (3TIFF) routine. .PP \fB"%s": Bad mode\fP. The specified .I mode parameter was not one of ``r'' (read), ``w'' (write), or ``a'' (append). .PP .BR "%s: Cannot open" . .IR TIFFOpen () was unable to open the specified filename for read/writing. .PP .BR "Cannot read TIFF header" . An error occurred while attempting to read the header information. .PP .BR "Error writing TIFF header" . An error occurred while writing the default header information for a new file. .PP .BR "Not a TIFF file, bad magic number %d (0x%x)" . The magic number in the header was not (hex) 0x4d4d or (hex) 0x4949. .PP .BR "Not a TIFF file, bad version number %d (0x%x)" . The version field in the header was not 42 (decimal). .PP .BR "Cannot append to file that has opposite byte ordering" . A file with a byte ordering opposite to the native byte ordering of the current machine was opened for appending (``a''). This is a limitation of the library. .SH "SEE ALSO" .IR libtiff (3TIFF), .IR TIFFClose (3TIFF) tiff-4.0.3/man/tiff2ps.10000644000212300117540000001612711244562247011617 00000000000000.\" $Id: tiff2ps.1,v 1.10 2009-01-12 02:05:19 bfriesen Exp $ .\" .\" Copyright (c) 1988-1997 Sam Leffler .\" Copyright (c) 1991-1997 Silicon Graphics, Inc. .\" .\" Permission to use, copy, modify, distribute, and sell this software and .\" its documentation for any purpose is hereby granted without fee, provided .\" that (i) the above copyright notices and this permission notice appear in .\" all copies of the software and related documentation, and (ii) the names of .\" Sam Leffler and Silicon Graphics may not be used in any advertising or .\" publicity relating to the software without the specific, prior written .\" permission of Sam Leffler and Silicon Graphics. .\" .\" THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, .\" EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY .\" WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. .\" .\" IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR .\" ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, .\" OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, .\" WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF .\" LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE .\" OF THIS SOFTWARE. .\" .ds Ps PostScript .if n .po 0 .TH TIFF2PS 1 "November 2, 2005" "libtiff" .SH NAME tiff2ps \- convert a .SM TIFF image to \*(Ps\*(Tm .SH SYNOPSIS .B tiff2ps [ .I options ] .I "input.tif ..." .SH DESCRIPTION .I tiff2ps reads .SM TIFF images and writes \*(Ps or Encapsulated \*(Ps (EPS) on the standard output. By default, .I tiff2ps writes Encapsulated \*(Ps for the first image in the specified .SM TIFF image file. .PP By default, .I tiff2ps will generate \*(Ps that fills a printed area specified by the .SM TIFF tags in the input file. If the file does not contain .I XResolution or .I YResolution tags, then the printed area is set according to the image dimensions. The .B \-w and .B \-h options (see below) can be used to set the dimensions of the printed area in inches; overriding any relevant .SM TIFF tags. .PP The \*(Ps generated for .SM RGB, palette, and .SM CMYK images uses the .I colorimage operator. The \*(Ps generated for greyscale and bilevel images uses the .I image operator. When the .I colorimage operator is used, \*(Ps code to emulate this operator on older \*(Ps printers is also generated. Note that this emulation code can be very slow. .PP Color images with associated alpha data are composited over a white background. .SH OPTIONS .TP .B \-1 Generate \*(Ps Level 1 (the default). .TP .B \-2 Generate \*(Ps Level 2. .TP .B \-3 Generate \*(Ps Level 3. It basically allows one to use the /flateDecode filter for ZIP compressed TIFF images. .TP .B \-a Generate output for all IFDs (pages) in the input file. .TP .B \-b Specify the bottom margin for the output (in inches). This does not affect the height of the printed image. .TP .B \-c Center the image in the output. This option only shows an effect if both the .B \-w and the .B \-h option are given. .TP .B \-d Set the initial .SM TIFF directory to the specified directory number. (NB: Directories are numbered starting at zero.) This option is useful for selecting individual pages in a multi-page (e.g. facsimile) file. .TP .B \-e Force the generation of Encapsulated \*(Ps (implies .BR \-z ). .TP .B \-h Specify the vertical size of the printed area (in inches). .TP .B \-H Specify the maximum height of image (in inches). Images with larger sizes will be split in several pages. Option .B \-L may be used for specifying size of split images overlapping. .TP .B \-W Specify the maximum width of image (in inches). Images with larger sizes will be split in several pages. Options .B \-L and .B \-W are mutually exclusive. .B \-i Enable/disable pixel interpolation. This option requires a single numeric value: zero to disable pixel interpolation and non-zero to enable. The default is enabled. .TP .B \-L Specify the size of overlapping for split images (in inches). Used in conjunction with .B \-H option and .B \-W option. .TP .B \-l Specify the left margin for the output (in inches). This does not affect the width of the printed image. .TP .B \-m Where possible render using the .I imagemask \*(Ps operator instead of the .I image operator. When this option is specified .I tiff2ps will use .I imagemask for rendering 1 bit deep images. If this option is not specified or if the image depth is greater than 1 then the .I image operator is used. .TP .B \-o Set the initial .SM TIFF directory to the .SM IFD at the specified file offset. This option is useful for selecting thumbnail images and the like which are hidden using the .I SubIFD tag. .TP .B \-p Force the generation of (non-Encapsulated) \*(Ps. .TP .B \-r 90|180|270|auto Rotate image by 90, 180, 270 degrees or auto. Auto picks the best fit for the image on the specified paper size (eg portrait or landscape) if -h or -w is specified. Rotation is in degrees counterclockwise. Auto rotates 90 degrees ccw to produce landscape. .TP .B \-s Generate output for a single IFD (page) in the input file. .TP .B \-w Specify the horizontal size of the printed area (in inches). .TP .B \-x Override resolution units specified in the TIFF as centimeters. .TP .B \-y Override resolution units specified in the TIFF as inches. .TP .B \-z When generating \*(Ps Level 2, data is scaled so that it does not image into the .I deadzone on a page (the outer margin that the printing device is unable to mark). This option suppresses this behavior. When \*(Ps Level 1 is generated, data is imaged to the entire printed page and this option has no affect. .SH EXAMPLES The following generates \*(Ps Level 2 for all pages of a facsimile: .RS .nf tiff2ps \-a2 fax.tif | lpr .fi .RE Note also that if you have version 2.6.1 or newer of Ghostscript then you can efficiently preview facsimile generated with the above command. .PP To generate Encapsulated \*(Ps for a the image at directory 2 of an image use: .RS .nf tiff2ps \-d 1 foo.tif .fi .RE (Notice that directories are numbered starting at zero.) .PP If you have a long image, it may be split in several pages: .RS .nf tiff2ps \-h11 \-w8.5 \-H14 \-L.5 foo.tif > foo.ps .fi .RE The page size is set to 8.5x11 by .B \-w and .B \-h options. We will accept a small amount of vertical compression, so .B \-H set to 14. Any pages between 11 and 14 inches will be fit onto one page. Pages longer than 14 inches are cut off at 11 and continued on the next page. The .B \-L.5 option says to repeat a half inch on the next page (to improve readability). .SH BUGS Because \*(Ps does not support the notion of a colormap, 8-bit palette images produce 24-bit \*(Ps images. This conversion results in output that is six times bigger than the original image and which takes a long time to send to a printer over a serial line. Matters are even worse for 4-, 2-, and 1-bit palette images. .PP Does not handle tiled images when generating \*(Ps Level I output. .SH "SEE ALSO" .BR pal2rgb (1), .BR tiffinfo (1), .BR tiffcp (1), .BR tiffgt (1), .BR tiffmedian (1), .BR tiff2bw (1), .BR tiffsv (1), .BR libtiff (3) .PP Libtiff library home page: .BR http://www.remotesensing.org/libtiff/ tiff-4.0.3/man/TIFFReadEncodedTile.3tiff0000644000212300117540000000566011244562247014541 00000000000000.\" $Id: TIFFReadEncodedTile.3tiff,v 1.3 2006-10-13 07:22:01 dron Exp $ .\" .\" Copyright (c) 1988-1997 Sam Leffler .\" Copyright (c) 1991-1997 Silicon Graphics, Inc. .\" .\" Permission to use, copy, modify, distribute, and sell this software and .\" its documentation for any purpose is hereby granted without fee, provided .\" that (i) the above copyright notices and this permission notice appear in .\" all copies of the software and related documentation, and (ii) the names of .\" Sam Leffler and Silicon Graphics may not be used in any advertising or .\" publicity relating to the software without the specific, prior written .\" permission of Sam Leffler and Silicon Graphics. .\" .\" THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, .\" EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY .\" WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. .\" .\" IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR .\" ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, .\" OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, .\" WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF .\" LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE .\" OF THIS SOFTWARE. .\" .if n .po 0 .TH TIFFReadEncodedTile 3TIFF "October 13, 2006" "libtiff" .SH NAME TIFFReadEncodedTile \- read and decode a tile of data from an open .SM TIFF file .SH SYNOPSIS .B "#include " .sp .BI "int TIFFReadEncodedTile(TIFF *" tif ", ttile_t " tile ", tdata_t " buf ", tsize_t " size ")" .SH DESCRIPTION Read the specified tile of data and place up to .I size bytes of decompressed information in the (user supplied) data buffer. .SH NOTES The value of .I tile is a ``raw tile number.'' That is, the caller must take into account whether or not the data are organized in separate planes (\c .IR PlanarConfiguration =2). .IR TIFFComputeTile automatically does this when converting an (x,y,z,sample) coordinate quadruple to a tile number. To read a full tile of data the data buffer should be at least as large as the value returned by .IR TIFFTileSize . .PP The library attempts to hide bit- and byte-ordering differences between the image and the native machine by converting data to the native machine order. Bit reversal is done if the .I FillOrder tag is opposite to the native machine bit order. 16- and 32-bit samples are automatically byte-swapped if the file was written with a byte order opposite to the native machine byte order, .SH "RETURN VALUES" The actual number of bytes of data that were placed in .I buf is returned; .IR TIFFReadEncodedTile returns \-1 if an error was encountered. .SH DIAGNOSTICS All error messages are directed to the .BR TIFFError (3TIFF) routine. .SH "SEE ALSO" .BR TIFFOpen (3TIFF), .BR TIFFReadRawTile (3TIFF), .BR TIFFReadTile (3TIFF), .BR libtiff (3TIFF) .PP Libtiff library home page: .BR http://www.remotesensing.org/libtiff/ tiff-4.0.3/man/Makefile.am0000644000212300117540000000521012005263022012164 00000000000000# Tag Image File Format (TIFF) Software # # Copyright (C) 2004, Andrey Kiselev # # Permission to use, copy, modify, distribute, and sell this software and # its documentation for any purpose is hereby granted without fee, provided # that (i) the above copyright notices and this permission notice appear in # all copies of the software and related documentation, and (ii) the names of # Sam Leffler and Silicon Graphics may not be used in any advertising or # publicity relating to the software without the specific, prior written # permission of Sam Leffler and Silicon Graphics. # # THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, # EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY # WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. # # IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR # ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, # OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, # WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF # LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE # OF THIS SOFTWARE. # Process this file with automake to produce Makefile.in. dist_man1_MANS = \ bmp2tiff.1 \ fax2ps.1 \ fax2tiff.1 \ gif2tiff.1 \ pal2rgb.1 \ ppm2tiff.1 \ ras2tiff.1 \ raw2tiff.1 \ rgb2ycbcr.1 \ sgi2tiff.1 \ thumbnail.1 \ tiff2bw.1 \ tiff2pdf.1 \ tiff2ps.1 \ tiff2rgba.1 \ tiffcmp.1 \ tiffcp.1 \ tiffcrop.1 \ tiffdither.1 \ tiffdump.1 \ tiffgt.1 \ tiffinfo.1 \ tiffmedian.1 \ tiffset.1 \ tiffsplit.1 \ tiffsv.1 dist_man3_MANS = \ libtiff.3tiff \ TIFFbuffer.3tiff \ TIFFClose.3tiff \ TIFFcodec.3tiff \ TIFFcolor.3tiff \ TIFFDataWidth.3tiff \ TIFFError.3tiff \ TIFFFieldDataType.3tiff \ TIFFFieldName.3tiff \ TIFFFieldPassCount.3tiff \ TIFFFieldReadCount.3tiff \ TIFFFieldTag.3tiff \ TIFFFieldWriteCount.3tiff \ TIFFFlush.3tiff \ TIFFGetField.3tiff \ TIFFmemory.3tiff \ TIFFOpen.3tiff \ TIFFPrintDirectory.3tiff \ TIFFquery.3tiff \ TIFFReadDirectory.3tiff \ TIFFReadEncodedStrip.3tiff \ TIFFReadEncodedTile.3tiff \ TIFFReadRawStrip.3tiff \ TIFFReadRawTile.3tiff \ TIFFReadRGBAImage.3tiff \ TIFFReadRGBAStrip.3tiff \ TIFFReadRGBATile.3tiff \ TIFFReadScanline.3tiff \ TIFFReadTile.3tiff \ TIFFRGBAImage.3tiff \ TIFFSetDirectory.3tiff \ TIFFSetField.3tiff \ TIFFsize.3tiff \ TIFFstrip.3tiff \ TIFFswab.3tiff \ TIFFtile.3tiff \ TIFFWarning.3tiff \ TIFFWriteDirectory.3tiff \ TIFFWriteEncodedStrip.3tiff \ TIFFWriteEncodedTile.3tiff \ TIFFWriteRawStrip.3tiff \ TIFFWriteRawTile.3tiff \ TIFFWriteScanline.3tiff \ TIFFWriteTile.3tiff tiff-4.0.3/man/raw2tiff.10000644000212300117540000001250611244563144011760 00000000000000.\" $Id: raw2tiff.1,v 1.7 2009-08-24 19:13:40 bfriesen Exp $ .\" .\" Copyright (c) 1990-1997 Sam Leffler .\" Copyright (c) 1991-1997 Silicon Graphics, Inc. .\" .\" Permission to use, copy, modify, distribute, and sell this software and .\" its documentation for any purpose is hereby granted without fee, provided .\" that (i) the above copyright notices and this permission notice appear in .\" all copies of the software and related documentation, and (ii) the names of .\" Sam Leffler and Silicon Graphics may not be used in any advertising or .\" publicity relating to the software without the specific, prior written .\" permission of Sam Leffler and Silicon Graphics. .\" .\" THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, .\" EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY .\" WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. .\" .\" IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR .\" ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, .\" OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, .\" WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF .\" LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE .\" OF THIS SOFTWARE. .\" .if n .po 0 .TH RAW2TIFF 1 "November 2, 2005" "libtiff" .SH NAME raw2tiff \- create a .SM TIFF file from a raw data .SH SYNOPSIS .B raw2tiff [ .I options ] .I input.raw .I output.tif .SH DESCRIPTION .I raw2tiff converts a raw byte sequence into .SM TIFF. By default, the .SM TIFF image is created with data samples packed (\c .IR PlanarConfiguration =1), compressed with the PackBits algorithm (\c .IR Compression =32773), and with each strip no more than 8 kilobytes. These characteristics can overridden, or explicitly specified with the options described below. .SH OPTIONS .TP .BI \-H " number" size of input image file header in bytes (0 by default). This amount of data just will be skipped from the start of file while reading. .TP .BI \-w " number" width of input image in pixels (can be guessed, see .SM .B "GUESSING THE IMAGE GEOMETRY" below). .TP .BI \-l " number" length of input image in lines (can be guessed, see .SM .B "GUESSING THE IMAGE GEOMETRY" below). .TP .BI \-b " number" number of bands in input image (1 by default). .TP .BI \-d " data_type" type of samples in input image, where .I data_type may be: .ta \w'\fBdouble \fR'u .br .B byte\t 8-bit unsigned integer (default), .br .B short\t 16-bit unsigned integer, .br .B long\t 32-bit unsigned integer, .br .B sbyte\t 8-bit signed integer, .br .B sshort\t 16-bit signed integer, .br .B slong\t 32-bit signed integer, .br .B float\t 32-bit IEEE floating point, .br .B double\t 64-bit IEEE floating point. .TP .BI \-i " config" type of samples interleaving in input image, where .I config may be: .ta \w'\fBpixel \fR'u .br .B pixel\t pixel interleaved data (default), .br .B band\t band interleaved data. .TP .BI \-p " photo" photometric interpretation (color space) of the input image, where .I photo may be: .ta \w'\fBminiswhite \fR'u .br .B miniswhite\t white color represented with 0 value, .br .B minisblack\t black color represented with 0 value (default), .br .B rgb\t image has RGB color model, .br .B cmyk\t image has CMYK (separated) color model, .br .B ycbcr\t image has YCbCr color model, .br .B cielab\t image has CIE L*a*b color model, .br .B icclab\t image has ICC L*a*b color model, .br .B itulab\t image has ITU L*a*b color model. .TP .B \-s swap bytes fetched from the input file. .TP .B \-L input data has LSB2MSB bit order (default). .TP .B \-M input data has MSB2LSB bit order. .TP .B \-c Specify a compression scheme to use when writing image data: .B "\-c none" for no compression, .B "\-c packbits" for the PackBits compression algorithm (the default), .B "\-c jpeg" for the baseline JPEG compression algorithm, .B "\-c zip" for the Deflate compression algorithm, and .B "\-c lzw" for Lempel-Ziv & Welch. .TP .BI \-r " number" Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approximately 8 kilobytes. .SH GUESSING THE IMAGE GEOMETRY .I raw2tiff can guess image width and height in case one or both of these parameters are not specified. If you omit one of those parameters, the complementary one will be calculated based on the file size (taking into account header size, number of bands and data type). If you omit both parameters, the statistical approach will be used. Utility will compute correlation coefficient between two lines at the image center using several appropriate line sizes and the highest absolute value of the coefficient will indicate the right line size. That is why you should be cautious with the very large images, because guessing process may take a while (depending on your system performance). Of course, the utility can't guess the header size, number of bands and data type, so it should be specified manually. If you don't know anything about your image, just try with the several combinations of those options. .P There is no magic, it is just a mathematical statistics, so it can be wrong in some cases. But for most ordinary images guessing method will work fine. .SH "SEE ALSO" .BR pal2rgb (1), .BR tiffinfo (1), .BR tiffcp (1), .BR tiffmedian (1), .BR libtiff (3) .PP Libtiff library home page: .BR http://www.remotesensing.org/libtiff/ tiff-4.0.3/man/TIFFsize.3tiff0000644000212300117540000000430111244562247012527 00000000000000.\" $Id: TIFFsize.3tiff,v 1.2 2005-11-02 11:07:18 dron Exp $ .\" .\" Copyright (c) 1988-1997 Sam Leffler .\" Copyright (c) 1991-1997 Silicon Graphics, Inc. .\" .\" Permission to use, copy, modify, distribute, and sell this software and .\" its documentation for any purpose is hereby granted without fee, provided .\" that (i) the above copyright notices and this permission notice appear in .\" all copies of the software and related documentation, and (ii) the names of .\" Sam Leffler and Silicon Graphics may not be used in any advertising or .\" publicity relating to the software without the specific, prior written .\" permission of Sam Leffler and Silicon Graphics. .\" .\" THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, .\" EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY .\" WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. .\" .\" IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR .\" ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, .\" OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, .\" WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF .\" LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE .\" OF THIS SOFTWARE. .\" .if n .po 0 .TH TIFFSIZE 3TIFF "October 15, 1995" "libtiff" .SH NAME TIFFScanlineSize, TIFFRasterScanlineSize, \- return the size of various items associated with an open .SM TIFF file .SH SYNOPSIS .B "#include " .sp .BI "tsize_t TIFFRasterScanlineSize(TIFF *" tif ")" .br .BI "tsize_t TIFFScanlineSize(TIFF *" tif ")" .SH DESCRIPTION .I TIFFScanlineSize returns the size in bytes of a row of data as it would be returned in a call to .IR TIFFReadScanline , or as it would be expected in a call to .IR TIFFWriteScanline . .PP .I TIFFRasterScanlineSize returns the size in bytes of a complete decoded and packed raster scanline.

The raster is assumed to be an array of width times rowsperstrip 32-bit entries, where width is the width of the image (TIFFTAG_IMAGEWIDTH) and rowsperstrip is the maximum lines in a strip (TIFFTAG_ROWSPERSTRIP). .PP The .IR row value should be the row of the first row in the strip (strip * rowsperstrip, zero based). .PP Note that the raster is assume to be organized such that the pixel at location (\fIx\fP,\fIy\fP) is \fIraster\fP[\fIy\fP*\fIwidth\fP+\fIx\fP]; with the raster origin in the .I lower-left hand corner of the strip. That is bottom to top organization. When reading a partial last strip in the file the last line of the image will begin at the beginning of the buffer. .PP Raster pixels are 8-bit packed red, green, blue, alpha samples. The macros .IR TIFFGetR , .IR TIFFGetG , .IR TIFFGetB , and .I TIFFGetA should be used to access individual samples. Images without Associated Alpha matting information have a constant Alpha of 1.0 (255). .PP See the .IR TIFFRGBAImage (3TIFF) page for more details on how various image types are converted to RGBA values. .SH NOTES Samples must be either 1, 2, 4, 8, or 16 bits. Colorimetric samples/pixel must be either 1, 3, or 4 (i.e. .I SamplesPerPixel minus .IR ExtraSamples ). .PP Palette image colormaps that appear to be incorrectly written as 8-bit values are automatically scaled to 16-bits. .PP .I TIFFReadRGBAStrip is just a wrapper around the more general .IR TIFFRGBAImage (3TIFF) facilities. It's main advantage over the similar .IR TIFFReadRGBAImage() function is that for large images a single buffer capable of holding the whole image doesn't need to be allocated, only enough for one strip. The .IR TIFFReadRGBATile() function does a similar operation for tiled images. .SH "RETURN VALUES" 1 is returned if the image was successfully read and converted. Otherwise, 0 is returned if an error was encountered. .SH DIAGNOSTICS All error messages are directed to the .IR TIFFError (3TIFF) routine. .PP .BR "Sorry, can not handle %d-bit pictures" . The image had .I BitsPerSample other than 1, 2, 4, 8, or 16. .PP .BR "Sorry, can not handle %d-channel images" .

There is usually a problem of application to handle the data properly and convert between different colorspaces for displaying and printing purposes. To simplify this task libtiff implements several color conversion routines itself. In particular, these routines used in .B TIFFRGBAImage(3TIFF) interface. .PP .B TIFFYCbCrToRGBInit() used to initialize .I YCbCr to .I RGB conversion state. Allocating and freeing of the .I ycbcr structure belongs to programmer. .I TIFFYCbCrToRGB defined in .B tiffio.h as .PP .RS .nf typedef struct { /* YCbCr->RGB support */ TIFFRGBValue* clamptab; /* range clamping table */ int* Cr_r_tab; int* Cb_b_tab; int32* Cr_g_tab; int32* Cb_g_tab; int32* Y_tab; } TIFFYCbCrToRGB; .fi .RE .PP .I luma is a float array of three values representing proportions of the red, green and blue in luminance, Y (see section 21 of the TIFF 6.0 specification, where the YCbCr images discussed). .I TIFFTAG_YCBCRCOEFFICIENTS holds that values in TIFF file. .I refBlackWhite is a float array of 6 values which specifies a pair of headroom and footroom image data values (codes) for each image component (see section 20 of the TIFF 6.0 specification where the colorinmetry fields discussed). .I TIFFTAG_REFERENCEBLACKWHITE is responsible for storing these values in TIFF file. Following code snippet should helps to understand the the technique: .PP .RS .nf float *luma, *refBlackWhite; uint16 hs, vs; /* Initialize structures */ ycbcr = (TIFFYCbCrToRGB*) _TIFFmalloc(TIFFroundup(sizeof(TIFFYCbCrToRGB), sizeof(long)) + 4*256*sizeof(TIFFRGBValue) + 2*256*sizeof(int) + 3*256*sizeof(int32)); if (ycbcr == NULL) { TIFFError("YCbCr->RGB", "No space for YCbCr->RGB conversion state"); exit(0); } TIFFGetFieldDefaulted(tif, TIFFTAG_YCBCRCOEFFICIENTS, &luma); TIFFGetFieldDefaulted(tif, TIFFTAG_REFERENCEBLACKWHITE, &refBlackWhite); if (TIFFYCbCrToRGBInit(ycbcr, luma, refBlackWhite) < 0) exit(0); /* Start conversion */ uint32 r, g, b; uint32 Y; int32 Cb, Cr; for each pixel in image TIFFYCbCrtoRGB(img->ycbcr, Y, Cb, Cr, &r, &g, &b); /* Free state structure */ _TIFFfree(ycbcr); .fi .RE .PP .PP .B TIFFCIELabToRGBInit() initializes the .I CIE L*a*b* 1976 to .I RGB conversion state. .B TIFFCIELabToRGB defined as .PP .RS .nf #define CIELABTORGB_TABLE_RANGE 1500 typedef struct { /* CIE Lab 1976->RGB support */ int range; /* Size of conversion table */ float rstep, gstep, bstep; float X0, Y0, Z0; /* Reference white point */ TIFFDisplay display; float Yr2r[CIELABTORGB_TABLE_RANGE + 1]; /* Conversion of Yr to r */ float Yg2g[CIELABTORGB_TABLE_RANGE + 1]; /* Conversion of Yg to g */ float Yb2b[CIELABTORGB_TABLE_RANGE + 1]; /* Conversion of Yb to b */ } TIFFCIELabToRGB; .fi .RE .PP .I display is a display device description, declared as .PP .RS .nf typedef struct { float d_mat[3][3]; /* XYZ -> luminance matrix */ float d_YCR; /* Light o/p for reference white */ float d_YCG; float d_YCB; uint32 d_Vrwr; /* Pixel values for ref. white */ uint32 d_Vrwg; uint32 d_Vrwb; float d_Y0R; /* Residual light for black pixel */ float d_Y0G; float d_Y0B; float d_gammaR; /* Gamma values for the three guns */ float d_gammaG; float d_gammaB; } TIFFDisplay; .fi .RE .PP For example, the one can use sRGB device, which has the following parameters: .PP .RS .nf TIFFDisplay display_sRGB = { { /* XYZ -> luminance matrix */ { 3.2410F, -1.5374F, -0.4986F }, { -0.9692F, 1.8760F, 0.0416F }, { 0.0556F, -0.2040F, 1.0570F } }, 100.0F, 100.0F, 100.0F, /* Light o/p for reference white */ 255, 255, 255, /* Pixel values for ref. white */ 1.0F, 1.0F, 1.0F, /* Residual light o/p for black pixel */ 2.4F, 2.4F, 2.4F, /* Gamma values for the three guns */ }; .fi .RE .PP .I refWhite is a color temperature of the reference white. The .I TIFFTAG_WHITEPOINT contains the chromaticity of the white point of the image from where the reference white can be calculated using following formulae: .PP .RS refWhite_Y = 100.0 .br refWhite_X = whitePoint_x / whitePoint_y * refWhite_Y .br refWhite_Z = (1.0 - whitePoint_x - whitePoint_y) / whitePoint_y * refWhite_X .br .RE .PP The conversion itself performed in two steps: at the first one we will convert .I CIE L*a*b* 1976 to .I CIE XYZ using .B TIFFCIELabToXYZ() routine, and at the second step we will convert .I CIE XYZ to .I RGB using .B TIFFXYZToRGB().

(A .I pseudo-tag is a parameter that is used to control the operation of the .SM TIFF library but whose value is not read or written to the underlying file.) The file must have been previously opened with .IR TIFFOpen (3TIFF). The tag is identified by .IR tag , one of the values defined in the include file .B tiff.h (see also the table below). The type and number of values returned is dependent on the tag being requested. The programming interface uses a variable argument list as prescribed by the .IR stdarg (3) interface. The returned values should only be interpreted if .IR TIFFGetField returns 1. .PP .IR TIFFVGetField is functionally equivalent to .IR TIFFGetField except that it takes a pointer to a variable argument list. .I TIFFVGetField is useful for layering interfaces on top of the functionality provided by .IR TIFFGetField . .PP .IR TIFFGetFieldDefaulted and .IR TIFFVGetFieldDefaulted are identical to .IR TIFFGetField and .IR TIFFVGetField , except that if a tag is not defined in the current directory and it has a default value, then the default value is returned. .PP The tags understood by .IR libtiff(3TIFF), the number of parameter values, and the types for the returned values are shown below. The data types are specified as in C and correspond to the types used to specify tag values to .IR TIFFSetField (3TIFF). Remember that .IR TIFFGetField returns parameter values, so all the listed data types are pointers to storage where values should be returned.

If the -1 passed in .I size parameter, the whole strip will be read. You should be sure you have enough space allocated for the buffer. .PP The library attempts to hide bit- and byte-ordering differences between the image and the native machine by converting data to the native machine order.

If the input TIFF file is of huge dimensions (greater than 10000 pixels height or width) convert the input image to a tiled TIFF if it is not already. .PP The standard output is standard output. Set the output file name with the .BI \-o " output.pdf" option. .PP All black and white files are compressed into a single strip CCITT G4 Fax compressed PDF, unless tiled, where tiled black and white images are compressed into tiled CCITT G4 Fax compressed PDF, .I libtiff CCITT support is assumed. .PP Color and grayscale data can be compressed using either JPEG compression, ITU-T T.81, or Zip/Deflate LZ77 compression. Set the compression type using the .B \-j or .B \-z options. JPEG compression support requires that .I libtiff be configured with JPEG support, and Zip/Deflate compression support requires that .I libtiff be configured with Zip support, in tiffconf.h. Use only one or the other of .B \-j and .B \-z. .PP If the input TIFF contains single strip CCITT G4 Fax compressed information, then that is written to the PDF file without transcoding, unless the options of no compression and no passthrough are set, .B \-d and .B \-n. .PP If the input TIFF contains JPEG or single strip Zip/Deflate compressed information, and they are configured, then that is written to the PDF file without transcoding, unless the options of no compression and no passthrough are set. .PP The default page size upon which the TIFF image is placed is determined by the resolution and extent of the image data. Default values for the TIFF image resolution can be set using the .B \-x and .B \-y options. The page size can be set using the .B \-p option for paper size, or .B \-w and .B \-l for paper width and length, then each page of the TIFF image is centered on its page.

.SH DESCRIPTION .I libtiff is a library for reading and writing data files encoded with the .I "Tag Image File" format, Revision 6.0 (or revision 5.0 or revision 4.0). This file format is suitable for archiving multi-color and monochromatic image data. .PP The library supports several compression algorithms, as indicated by the .I Compression field, including: no compression (1), .SM CCITT 1D Huffman compression (2), .SM CCITT Group 3 Facsimile compression (3), .SM CCITT Group 4 Facsimile compression (4), Lempel-Ziv & Welch compression (5), baseline JPEG compression (7), word-aligned 1D Huffman compression (32771), and PackBits compression (32773). In addition, several nonstandard compression algorithms are supported: the 4-bit compression algorithm used by the .I ThunderScan program (32809) (decompression only), NeXT's 2-bit compression algorithm (32766) (decompression only), an experimental LZ-style algorithm known as Deflate (32946), and an experimental CIE LogLuv compression scheme designed for images with high dynamic range (32845 for LogL and 32845 for LogLuv). Directory information may be in either little- or big-endian byte order\-byte swapping is automatically done by the library. Data bit ordering may be either Most Significant Bit (\c .SM MSB\c ) to Least Significant Bit (\c .SM LSB\c ) or .SM LSB to .SM MSB. Finally, the library does not support files in which the .IR BitsPerSample , .IR Compression , .IR MinSampleValue , or .IR MaxSampleValue fields are defined differently on a per-sample basis (in Rev. 6.0 the .I Compression tag is not defined on a per-sample basis, so this is immaterial). .SH "DATA TYPES" The library makes extensive use of C typedefs to promote portability. Two sets of typedefs are used, one for communication with clients of the library and one for internal data structures and parsing of the .SM TIFF format. The following typedefs are exposed to users either through function definitions or through parameters passed through the varargs interfaces. .in +.5i .sp 5p .ta +\w'typedef unsigned <\fIthing\fP> uint32; 'u .nf typedef unsigned short uint16; 16-bit unsigned integer typedef unsigned <\fIthing\fP> uint32; 32-bit unsigned integer .sp 5p typedef unsigned int ttag_t; directory tag typedef uint16 tdir_t; directory index typedef uint16 tsample_t; sample number typedef uint32 tstrip_t; strip number typedef uint32 ttile_t; tile number typedef int32 tsize_t; i/o size in bytes typedef void* tdata_t; image data ref typedef void* thandle_t; client data handle typedef int32 toff_t; file offset .fi .sp 5p .in -.5i Note that .IR tstrip_t , .IR ttile_t , and .I tsize_t are constrained to be no more than 32-bit quantities by 32-bit fields they are stored in in the .SM TIFF image. Likewise .I tsample_t is limited by the 16-bit field used to store the .I SamplesPerPixel tag. .I tdir_t constrains the maximum number of .SM IFDs that may appear in an image and may be an arbitrary size (w/o penalty). .I ttag_t must be either int, unsigned int, pointer, or double because the library uses a varargs interface and .SM "ANSI C" restricts the type of the parameter before an ellipsis to be a promoted type. .I toff_t is defined as int32 because TIFF file offsets are (unsigned) 32-bit quantities. A signed value is used because some interfaces return \-1 on error. Finally, note that user-specified data references are passed as opaque handles and only cast at the lowest layers where their type is presumed. .SH "LIST OF ROUTINES" The following routines are part of the library. Consult specific manual pages for details on their operation; on most systems doing ``man function-name'' will work. .sp .nf .ta \w'TIFFCheckpointDirectory'u+2n \fIName\fP \fIDescription\fP .sp 5p TIFFCheckpointDirectory writes the current state of the directory TIFFCheckTile very x,y,z,sample is within image TIFFCIELabToRGBInit initialize CIE L*a*b* 1976 to RGB conversion state TIFFCIELabToXYZ perform CIE L*a*b* 1976 to CIE XYZ conversion TIFFClientOpen open a file for reading or writing TIFFClose close an open file TIFFComputeStrip return strip containing y,sample TIFFComputeTile return tile containing x,y,z,sample TIFFCurrentDirectory return index of current directory TIFFCurrentRow return index of current scanline TIFFCurrentStrip return index of current strip TIFFCurrentTile return index of current tile TIFFDataWidth return the size of TIFF data types TIFFError library error handler TIFFFdOpen open a file for reading or writing TIFFFieldDataType get data type from field information TIFFFieldName get field name from field information TIFFFieldPassCount get whether to pass a value count to Get/SetField TIFFFieldReadCount get number of values to be read from field TIFFFieldTag get tag value from field information TIFFFieldWithName get field information given field name TIFFFieldWithTag get field information given tag TIFFFieldWriteCount get number of values to be written to field TIFFFileName return name of open file TIFFFileno return open file descriptor TIFFFindCODEC find standard codec for the specific scheme TIFFFindField get field information given tag and data type TIFFFlush flush all pending writes TIFFFlushData flush pending data writes TIFFGetBitRevTable return bit reversal table TIFFGetField return tag value in current directory TIFFGetFieldDefaulted return tag value in current directory TIFFGetMode return open file mode TIFFGetVersion return library version string TIFFIsCODECConfigured check, whether we have working codec TIFFIsMSB2LSB return true if image data is being returned with bit 0 as the most significant bit TIFFIsTiled return true if image data is tiled TIFFIsByteSwapped return true if image data is byte-swapped TIFFNumberOfStrips return number of strips in an image TIFFNumberOfTiles return number of tiles in an image TIFFOpen open a file for reading or writing TIFFPrintDirectory print description of the current directory TIFFReadBufferSetup specify i/o buffer for reading TIFFReadDirectory read the next directory TIFFReadEncodedStrip read and decode a strip of data TIFFReadEncodedTile read and decode a tile of data TIFFReadRawStrip read a raw strip of data TIFFReadRawTile read a raw tile of data TIFFReadRGBAImage read an image into a fixed format raster TIFFReadScanline read and decode a row of data TIFFReadTile read and decode a tile of data TIFFRegisterCODEC override standard codec for the specific scheme TIFFReverseBits reverse bits in an array of bytes TIFFRGBAImageBegin setup decoder state for TIFFRGBAImageGet TIFFRGBAImageEnd release TIFFRGBAImage decoder state TIFFRGBAImageGet read and decode an image TIFFRGBAImageOK is image readable by TIFFRGBAImageGet TIFFScanlineSize return size of a scanline TIFFSetDirectory set the current directory TIFFSetSubDirectory set the current directory TIFFSetErrorHandler set error handler function TIFFSetField set a tag's value in the current directory TIFFSetWarningHandler set warning handler function TIFFStripSize returns size of a strip TIFFRawStripSize returns the number of bytes in a raw strip TIFFSwabShort swap bytes of short TIFFSwabLong swap bytes of long TIFFSwabArrayOfShort swap bytes of an array of shorts TIFFSwabArrayOfLong swap bytes of an array of longs TIFFTileRowSize return size of a row in a tile TIFFTileSize return size of a tile TIFFUnRegisterCODEC unregisters the codec TIFFVGetField return tag value in current directory TIFFVGetFieldDefaulted return tag value in current directory TIFFVSetField set a tag's value in the current directory TIFFVStripSize returns the number of bytes in a strip TIFFWarning library warning handler TIFFWriteDirectory write the current directory TIFFWriteEncodedStrip compress and write a strip of data TIFFWriteEncodedTile compress and write a tile of data TIFFWriteRawStrip write a raw strip of data TIFFWriteRawTile write a raw tile of data TIFFWriteScanline write a scanline of data TIFFWriteTile compress and write a tile of data TIFFXYZToRGB perform CIE XYZ to RGB conversion TIFFYCbCrToRGBInit initialize YCbCr to RGB conversion state TIFFYCbCrtoRGB perform YCbCr to RGB conversion .sp Auxiliary functions: _TIFFfree free memory buffer _TIFFmalloc dynamically allocate memory buffer _TIFFmemcmp compare contents of the memory buffers _TIFFmemcpy copy contents of the one buffer to another _TIFFmemset fill memory buffer with a constant byte _TIFFrealloc dynamically reallocate memory buffer .fi .SH "TAG USAGE" The table below lists the .SM TIFF tags that are recognized and handled by the library. If no use is indicated in the table, then the library reads and writes the tag, but does not use it internally. Note that some tags are meaningful only when a particular compression scheme is being used; e.g. .I Group3Options is only useful if .I Compression is set to .SM CCITT Group 3 encoding. Tags of this sort are considered .I codec-specific tags and the library does not recognize them except when the .I Compression tag has been previously set to the relevant compression scheme. .sp .nf .ta \w'TIFFTAG_JPEGTABLESMODE'u+2n +\w'Value'u+2n +\w'R/W'u+2n \fITag Name\fP \fIValue\fP \fIR/W\fP \fILibrary Use/Notes\fP .sp 5p .nf Artist 315 R/W BadFaxLines 326 R/W BitsPerSample 258 R/W lots CellLength 265 parsed but ignored CellWidth 264 parsed but ignored CleanFaxData 327 R/W ColorMap 320 R/W ColorResponseUnit 300 parsed but ignored Compression 259 R/W choosing codec ConsecutiveBadFaxLines 328 R/W Copyright 33432 R/W DataType 32996 R obsoleted by SampleFormat tag DateTime 306 R/W DocumentName 269 R/W DotRange 336 R/W ExtraSamples 338 R/W lots FaxRecvParams 34908 R/W FaxSubAddress 34909 R/W FaxRecvTime 34910 R/W FillOrder 266 R/W control bit order FreeByteCounts 289 parsed but ignored FreeOffsets 288 parsed but ignored GrayResponseCurve 291 parsed but ignored GrayResponseUnit 290 parsed but ignored Group3Options 292 R/W used by Group 3 codec Group4Options 293 R/W HostComputer 316 R/W ImageDepth 32997 R/W tile/strip calculations ImageDescription 270 R/W ImageLength 257 R/W lots ImageWidth 256 R/W lots InkNames 333 R/W InkSet 332 R/W JPEGTables 347 R/W used by JPEG codec Make 271 R/W Matteing 32995 R obsoleted by ExtraSamples tag MaxSampleValue 281 R/W MinSampleValue 280 R/W Model 272 R/W NewSubFileType 254 R/W called SubFileType in spec NumberOfInks 334 R/W Orientation 274 R/W PageName 285 R/W PageNumber 297 R/W PhotometricInterpretation 262 R/W used by Group 3 and JPEG codecs PlanarConfiguration 284 R/W data i/o Predictor 317 R/W used by LZW and Deflate codecs PrimaryChromacities 319 R/W ReferenceBlackWhite 532 R/W ResolutionUnit 296 R/W used by Group 3 codec RowsPerStrip 278 R/W data i/o SampleFormat 339 R/W SamplesPerPixel 277 R/W lots SMinSampleValue 340 R/W SMaxSampleValue 341 R/W Software 305 R/W StoNits 37439 R/W StripByteCounts 279 R/W data i/o StripOffsets 273 R/W data i/o SubFileType 255 R/W called OSubFileType in spec TargetPrinter 337 R/W Thresholding 263 R/W TileByteCounts 324 R/W data i/o TileDepth 32998 R/W tile/strip calculations TileLength 323 R/W data i/o TileOffsets 324 R/W data i/o TileWidth 322 R/W data i/o TransferFunction 301 R/W WhitePoint 318 R/W XPosition 286 R/W XResolution 282 R/W YCbCrCoefficients 529 R/W used by TIFFRGBAImage support YCbCrPositioning 531 R/W tile/strip size calulcations YCbCrSubsampling 530 R/W YPosition 286 R/W YResolution 283 R/W used by Group 3 codec .SH "PSEUDO TAGS" In addition to the normal .SM TIFF tags the library supports a collection of tags whose values lie in a range outside the valid range of .SM TIFF tags. These tags are termed .I pseud-tags and are used to control various codec-specific functions within the library. The table below summarizes the defined pseudo-tags. .sp .nf .ta \w'TIFFTAG_JPEGTABLESMODE'u+2n +\w'Codec'u+2n +\w'R/W'u+2n \fITag Name\fP \fICodec\fP \fIR/W\fP \fILibrary Use/Notes\fP .sp 5p .nf TIFFTAG_FAXMODE G3 R/W general codec operation TIFFTAG_FAXFILLFUNC G3/G4 R/W bitmap fill function TIFFTAG_JPEGQUALITY JPEG R/W compression quality control TIFFTAG_JPEGCOLORMODE JPEG R/W control colorspace conversions TIFFTAG_JPEGTABLESMODE JPEG R/W control contents of \fIJPEGTables\fP tag TIFFTAG_ZIPQUALITY Deflate R/W compression quality level TIFFTAG_PIXARLOGDATAFMT PixarLog R/W user data format TIFFTAG_PIXARLOGQUALITY PixarLog R/W compression quality level TIFFTAG_SGILOGDATAFMT SGILog R/W user data format .fi .TP .B TIFFTAG_FAXMODE Control the operation of the Group 3 codec. Possible values (independent bits that can be combined by or'ing them together) are: FAXMODE_CLASSIC (enable old-style format in which the .SM RTC is written at the end of the last strip), FAXMODE_NORTC (opposite of FAXMODE_CLASSIC; also called FAXMODE_CLASSF), FAXMODE_NOEOL (do not write .SM EOL codes at the start of each row of data), FAXMODE_BYTEALIGN (align each encoded row to an 8-bit boundary), FAXMODE_WORDALIGN (align each encoded row to an 16-bit boundary), The default value is dependent on the compression scheme; this pseudo-tag is used by the various G3 and G4 codecs to share code. .TP .B TIFFTAG_FAXFILLFUNC Control the function used to convert arrays of black and white runs to packed bit arrays. This hook can be used to image decoded scanlines in multi-bit depth rasters (e.g. for display in colormap mode) or for other purposes. The default value is a pointer to a builtin function that images packed bilevel data. .TP .B TIFFTAG_IPTCNEWSPHOTO Tag contaings image metadata per the IPTC newsphoto spec: Headline, captioning, credit, etc... Used by most wire services. .TP .B TIFFTAG_PHOTOSHOP Tag contains Photoshop captioning information and metadata. Photoshop uses in parallel and redundantly alongside IPTCNEWSPHOTO information. .TP .B TIFFTAG_JPEGQUALITY Control the compression quality level used in the baseline algorithm. Note that quality levels are in the range 0-100 with a default value of 75. .TP .B TIFFTAG_JPEGCOLORMODE Control whether or not conversion is done between RGB and YCbCr colorspaces. Possible values are: JPEGCOLORMODE_RAW (do not convert), and JPEGCOLORMODE_RGB (convert to/from RGB) The default value is JPEGCOLORMODE_RAW. .TP .B TIFFTAG_JPEGTABLESMODE Control the information written in the .I JPEGTables tag. Possible values (independent bits that can be combined by or'ing them together) are: JPEGTABLESMODE_QUANT (include quantization tables), and JPEGTABLESMODE_HUFF (include Huffman encoding tables). The default value is JPEGTABLESMODE_QUANT|JPEGTABLESMODE_HUFF. .TP .B TIFFTAG_ZIPQUALITY Control the compression technique used by the Deflate codec. Quality levels are in the range 1-9 with larger numbers yielding better compression at the cost of more computation. The default quality level is 6 which yields a good time-space tradeoff. .TP .B TIFFTAG_PIXARLOGDATAFMT Control the format of user data passed .I in to the PixarLog codec when encoding and passed .I out from when decoding. Possible values are: PIXARLOGDATAFMT_8BIT for 8-bit unsigned pixels, PIXARLOGDATAFMT_8BITABGR for 8-bit unsigned ABGR-ordered pixels, PIXARLOGDATAFMT_11BITLOG for 11-bit log-encoded raw data, PIXARLOGDATAFMT_12BITPICIO for 12-bit PICIO-compatible data, PIXARLOGDATAFMT_16BIT for 16-bit signed samples, and PIXARLOGDATAFMT_FLOAT for 32-bit IEEE floating point samples. .TP .B TIFFTAG_PIXARLOGQUALITY Control the compression technique used by the PixarLog codec. This value is treated identically to TIFFTAG_ZIPQUALITY; see the above description. .TP .B TIFFTAG_SGILOGDATAFMT Control the format of client data passed .I in to the SGILog codec when encoding and passed .I out from when decoding. Possible values are: SGILOGDATAFMT_FLTXYZ for converting between LogLuv and 32-bit IEEE floating valued XYZ pixels, SGILOGDATAFMT_16BITLUV for 16-bit encoded Luv pixels, SGILOGDATAFMT_32BITRAW and SGILOGDATAFMT_24BITRAW for no conversion of data, SGILOGDATAFMT_8BITRGB for returning 8-bit RGB data (valid only when decoding LogLuv-encoded data), SGILOGDATAFMT_FLTY for converting between LogL and 32-bit IEEE floating valued Y pixels, SGILOGDATAFMT_16BITL for 16-bit encoded L pixels, and SGILOGDATAFMT_8BITGRY for returning 8-bit greyscale data (valid only when decoding LogL-encoded data). .SH DIAGNOSTICS All error messages are directed through the .IR TIFFError routine. By default messages are directed to .B stderr in the form: .IR "module: message\en." Warning messages are likewise directed through the .IR TIFFWarning routine. .SH "SEE ALSO" .BR fax2tiff (1), .BR gif2tiff (1), .BR pal2rgb (1), .BR ppm2tiff (1), .BR rgb2ycbcr (1), .BR ras2tiff (1), .BR raw2tiff (1), .BR sgi2tiff (1), .BR tiff2bw (1), .BR tiffdither (1), .BR tiffdump (1), .BR tiffcp (1), .BR tiffcmp (1), .BR tiffgt (1), .BR tiffinfo (1), .BR tiffmedian (1), .BR tiffsplit (1), .BR tiffsv (1). .PP .BR "Tag Image File Format Specification \(em Revision 6.0" , an Aldus Technical Memorandum. .PP .BR "The Spirit of TIFF Class F" , an appendix to the TIFF 5.0 specification prepared by Cygnet Technologies. .PP Libtiff library home page: .BR http://www.remotesensing.org/libtiff/ .SH BUGS The library does not support multi-sample images where some samples have different bits/sample. .PP The library does not support random access to compressed data that is organized with more than one row per tile or strip. tiff-4.0.3/man/ras2tiff.10000644000212300117540000000570111244562247011756 00000000000000.\" $Id: ras2tiff.1,v 1.4 2006-04-20 12:17:19 dron Exp $ .\" .\" Copyright (c) 1990-1997 Sam Leffler .\" Copyright (c) 1991-1997 Silicon Graphics, Inc. .\" .\" Permission to use, copy, modify, distribute, and sell this software and .\" its documentation for any purpose is hereby granted without fee, provided .\" that (i) the above copyright notices and this permission notice appear in .\" all copies of the software and related documentation, and (ii) the names of .\" Sam Leffler and Silicon Graphics may not be used in any advertising or .\" publicity relating to the software without the specific, prior written .\" permission of Sam Leffler and Silicon Graphics. .\" .\" THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, .\" EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY .\" WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. .\" .\" IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR .\" ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, .\" OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, .\" WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF .\" LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE .\" OF THIS SOFTWARE. .\" .if n .po 0 .TH RAS2TIFF 1 "November 2, 2005" "libtiff" .SH NAME ras2tiff \- create a .SM TIFF file from a Sun rasterfile .SH SYNOPSIS .B ras2tiff [ .I options ] .I input.ras .I output.tif .SH DESCRIPTION .I ras2tiff converts a file in the Sun rasterfile format to .SM TIFF. By default, the .SM TIFF image is created with data samples packed (\c .IR PlanarConfiguration =1), compressed with the Lempel-Ziv & Welch algorithm (\c .IR Compression =5), and with each strip no more than 8 kilobytes. These characteristics can overridden, or explicitly specified with the options described below. .PP Any colormap information in the rasterfile is carried over to the .SM TIFF file by including a .I Colormap tag in the output file.

The generated colormap has, by default, 256 entries. The image data is quantized by mapping each pixel to the closest color values in the colormap. .SH OPTIONS .TP .B \-c Specify the compression to use for data written to the output file: .B none for no compression, .B packbits for PackBits compression, .B lzw for Lempel-Ziv & Welch compression, and .B zip for Deflate compression. By default .I tiffmedian will compress data according to the value of the .I Compression tag found in the source file. .IP .SM LZW compression can be specified together with a .I predictor value. A predictor value of 2 causes each scanline of the output image to undergo horizontal differencing before it is encoded; a value of 1 forces each scanline to be encoded without differencing. LZW-specific options are specified by appending a ``:''-separated list to the ``lzw'' option; e.g. .B "\-c lzw:2" for .SM LZW compression with horizontal differencing. .TP .B \-C Specify the number of entries to use in the generated colormap. By default all 256 entries/colors are used. .TP .B \-f Apply Floyd-Steinberg dithering before selecting a colormap entry. .TP .B \-r Specify the number of rows (scanlines) in each strip of data written to the output file. By default, .I tiffmedian attempts to set the rows/strip that no more than 8 kilobytes of data appear in a strip. .SH NOTES This program is derived from Paul Heckbert's .I median program. .SH "SEE ALSO" .BR pal2rgb (1), .BR tiffinfo (1), .BR tiffcp (1), .BR tiffcmp (1), .BR libtiff (3TIFF) .PP .BR "Color Image Quantization for Frame Buffer Display", Paul Heckbert, SIGGRAPH proceedings, 1982, pp. 297-307. .PP Libtiff library home page: .BR http://www.remotesensing.org/libtiff/ tiff-4.0.3/Makefile.in0000644000212300117540000007362512027361162011451 00000000000000# Makefile.in generated by automake 1.12.4 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2012 Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ # Tag Image File Format (TIFF) Software # # Copyright (C) 2004, Andrey Kiselev # # Permission to use, copy, modify, distribute, and sell this software and # its documentation for any purpose is hereby granted without fee, provided # that (i) the above copyright notices and this permission notice appear in # all copies of the software and related documentation, and (ii) the names of # Sam Leffler and Silicon Graphics may not be used in any advertising or # publicity relating to the software without the specific, prior written # permission of Sam Leffler and Silicon Graphics. # # THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, # EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY # WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. # # IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR # ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, # OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, # WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF # LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE # OF THIS SOFTWARE. # Process this file with automake to produce Makefile.in.

This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

This is probably a bug in the specification. * In this case, TIFFTAG_COLORRESPONSECURVE is ignored. * This might make sense if TIFFTAG_COLORMAP was 8 bits wide. * * TIFFTAG_COLORMAP is often incorrectly written as ranging from * 0 to 255 rather than from 0 to 65535. CheckAndCorrectColormap() * takes care of this. * * Only ORIENTATION_TOPLEFT is supported correctly. This is the * default TIFF and X orientation. Other orientations will be * displayed incorrectly. * * There is no support for or use of 3/3/2 DirectColor visuals. * TIFFTAG_MINSAMPLEVALUE and TIFFTAG_MAXSAMPLEVALUE are not supported. * * Only TIFFTAG_BITSPERSAMPLE values that are 1, 2, 4 or 8 are supported. */ #include #include #include #include #include #include #include #include #include #include #include #include #include #define XK_MISCELLANY #include #include "xtifficon.h" #define TIFF_GAMMA "2.2" /* default gamma from the TIFF 5.0 spec */ #define ROUND(x) (uint16) ((x) + 0.5) #define SCALE(x, s) (((x) * 65535L) / (s)) #define MCHECK(m) if (!m) { fprintf(stderr, "malloc failed\n"); exit(0); } #define MIN(a, b) (((a) < (b)) ?

Usage: iptcutil -t | -b [-i file] [-o file] output Notes: You tell the program the "type" of input file via the -t and -b switches. The -t says that the input is text, while the -b says that the input is binary IPTC. You can use either the -i or the -o switches to tell the program what the input and output files will be, or use simple piping. Author: William T. Radcliffe (billr@corbis.com) Parts of this program were derived from other places. The original binary to text conversion was taken from the PHP distribution and the tokenizer was written many years ago, by someone else as well.

It allows you extract tokens one at a time from a string of characters. The characters used for white space, for break characters, and for quotes can be specified. Also, characters in the string can be preceded by a specifiable escape character which removes any special meaning the character may have. There are a lot of formal parameters in this subroutine call, but once you get familiar with them, this routine is fairly easy to use. "#define" macros can be used to generate simpler looking calls for commonly used applications of this routine. First, some terminology: token: used here, a single unit of information in the form of a group of characters. white space: space that gets ignored (except within quotes or when escaped), like blanks and tabs. in addition, white space terminates a non-quoted token. break character: a character that separates non-quoted tokens. commas are a common break character. the usage of break characters to signal the end of a token is the same as that of white space, except multiple break characters with nothing or only white space between generate a null token for each two break characters together. for example, if blank is set to be the white space and comma is set to be the break character, the line ... A, B, C , , DEF ... consists of 5 tokens: 1) "A" 2) "B" 3) "C" 4) "" (the null string) 5) "DEF" quote character: a character that, when surrounding a group of other characters, causes the group of characters to be treated as a single token, no matter how many white spaces or break characters exist in the group. also, a token always terminates after the closing quote. for example, if ' is the quote character, blank is white space, and comma is the break character, the following string ... A, ' B, CD'EF GHI ... consists of 4 tokens: 1) "A" 2) " B, CD" (note the blanks & comma) 3) "EF" 4) "GHI" the quote characters themselves do not appear in the resultant tokens. the double quotes are delimiters i use here for documentation purposes only. escape character: a character which itself is ignored but which causes the next character to be used as is. ^ and \ are often used as escape characters. an escape in the last position of the string gets treated as a "normal" (i.e., non-quote, non-white, non-break, and non-escape) character. for example, assume white space, break character, and quote are the same as in the above examples, and further, assume that ^ is the escape character. then, in the string ... ABC, ' DEF ^' GH' I ^ J K^ L ^ ... there are 7 tokens: 1) "ABC" 2) " DEF ' GH" 3) "I" 4) " " (a lone blank) 5) "J" 6) "K L" 7) "^" (passed as is at end of line) OK, now that you have this background, here's how to call "tokenizer": result=tokenizer(flag,token,maxtok,string,white,break,quote,escape, brkused,next,quoted) result: 0 if we haven't reached EOS (end of string), and 1 if we have (this is an "int"). flag: right now, only the low order 3 bits are used. 1 => convert non-quoted tokens to upper case 2 => convert non-quoted tokens to lower case 0 => do not convert non-quoted tokens (this is a "char"). token: a character string containing the returned next token (this is a "char[]"). maxtok: the maximum size of "token". characters beyond "maxtok" are truncated (this is an "int"). string: the string to be parsed (this is a "char[]"). white: a string of the valid white spaces. example: char whitesp[]={" \t"}; blank and tab will be valid white space (this is a "char[]"). break: a string of the valid break characters. example: char breakch[]={";,"}; semicolon and comma will be valid break characters (this is a "char[]"). IMPORTANT: do not use the name "break" as a C variable, as this is a reserved word in C. quote: a string of the valid quote characters. an example would be char whitesp[]={"'\""); (this causes single and double quotes to be valid) note that a token starting with one of these characters needs the same quote character to terminate it. for example, "ABC ' is unterminated, but "DEF" and 'GHI' are properly terminated. note that different quote characters can appear on the same line; only for a given token do the quote characters have to be the same (this is a "char[]"). escape: the escape character (NOT a string ... only one allowed). use zero if none is desired (this is a "char"). brkused: the break character used to terminate the current token. if the token was quoted, this will be the quote used. if the token is the last one on the line, this will be zero (this is a pointer to a "char"). next: this variable points to the first character of the next token. it gets reset by "tokenizer" as it steps through the string. set it to 0 upon initialization, and leave it alone after that. you can change it if you want to jump around in the string or re-parse from the beginning, but be careful (this is a pointer to an "int"). quoted: set to 1 (true) if the token was quoted and 0 (false) if not. you may need this information (for example: in C, a string with quotes around it is a character string, while one without is an identifier).

Poelman (WSAT)" Subject: Potential TIFF library additions Delivery-Date: Fri, 01 Aug 1997 19:21:06 -0700 Sam, You probably don't remember me, but I sent in a couple of bug fixes regarding the TIFF library about a 16 months ago or so... I just wanted to send you two other additions that I have made to our local version of the TIFF library in hopes that you will want to incorporate them into your next major release of the TIFF library. (These additions are based on TIFF version 3.4beta31, but they sit on top of the library so they shouldn't be much trouble to incorporate them into any more recent version.) They are internally documented to a reasonable extent and we've been successfully using them in our code here for over a year. If you think they would make good additions to the TIFF library, I'd be happy to clean them up more, document them more, and/or integrate them with the latest version of the TIFF library, but I figured I'd see if you were interested in using them before I went to all that trouble. TIFF Image Iterator ------------------- Your ReadRGBA() routine works well for reading many different formats (TILED, STIP, compressed or not, etc.) of the most basic types of data (RGB, 8-bit greyscale, 8-bit colormapped) into an SGI-style data array, and serves as a good template for users with other needs. I used it as an exmaple of how to make an iterator which, rather than fill a data array, calls an arbitrary user-supplied callback function for each "chunk" of data - that "chunk" might be a strip or a tile, and might have one sample-per-pixel or two, and might be 8-bit data or 16-bit or 24-bit. The callback function can do whatever it wants with the data - store it in a big array, convert it to RGBA, or draw it directly to the screen. I was able to use this iterator to read 16-bit greyscale and 32- and 64-bit floating point data, which wasn't possible with ReadRGBA(). I have tested this routine with 8- and 16-bit greyscale data as well as with 32- and 64-bit floating point data. I believe nearly all of our data is organized in strips, so actually I'd appreciate it if you had some tiled images that I could test it with. It should certainly be possible and would be cleanest to reimplement ReadRGBA() in terms of the image iterator, but I haven't done that. Private Sub-Directory Read/Write -------------------------------- TIFF-PL is a Phillips Laboratory extension to the TIFF tags that allows us to store satellite imaging-specific information in a TIFF format, such as the satellite's trajectory, the imaging time, etc. In order to give us the flexibility to modify the tag definitions without getting approval from the TIFF committee every time, we were given only three TIFF tags - a PL signature, a PL version number, and PL directory offset, which lists the position in the file at which to find a private sub-directory of tags-value pairs. So I wrote two routines: TIFFWritePrivateDataSubDirectory(), which takes a list of tags and a "get" function and writes the tag values into the TIFF file, returning the offset within the file at which it wrote the directory; and TIFFReadPrivateDataSubDirectory(), which takes an offset, a list of tags, and a "set" function and reads all the data from the private directory. The functions themselves are pretty simple. (The files are huge because I had to basically copy all of the tif_dirread.c and tif_dirwrite.c files in order to access the various fetching routines which were all declared static and therefore inaccessible in the TIFF library.) I'm including the four source files (tif_imgiter.h, tif_imgiter.c, tif_pdsdirread.c, tif_pdsdirwrite.c) in case you want to take a look at them. I can also send you some sample code that uses them if you like. If you're interested in having them incorporated into the standard TIFF library, I'd be happy to do that integration and clean up and document the routines. (For example, I've already realized that instead of limiting the SEP callback function to three bands (R,G,B) it should take an array to enable the handling of n-banded multi-spectral data...) If not, I'll just leave them as they are, since they work fine for us now. Holler if you have any questions. -- Conrad __________________________________________________________________ Capt Conrad J.

Poelman, PL/WSAT, Kirtland AFB, NM on 26 Mar 96. * * This file contains code to allow a calling program to "iterate" over each * pixels in an image as it is read from the file. The iterator takes care of * reading strips versus (possibly clipped) tiles, decoding the information * according to the decoding method, and so on, so that calling program can * ignore those details. The calling program does, however, need to be * conscious of the type of the pixel data that it is receiving. * * For reasons of efficiency, the callback function actually gets called for * "blocks" of pixels rather than for individual pixels. The format of the * callback arguments is given below. * * This code was taken from TIFFReadRGBAImage() in tif_getimage.c of the original * TIFF distribution, and simplified and generalized to provide this general * iteration capability. Those routines could certainly be re-implemented in terms * of a TIFFImageIter if desired. * */ #include "tiffiop.h" #include "tif_imageiter.h" #include #include static int gtTileContig(TIFFImageIter*, void *udata, uint32, uint32); static int gtTileSeparate(TIFFImageIter*, void *udata, uint32, uint32); static int gtStripContig(TIFFImageIter*, void *udata, uint32, uint32); static int gtStripSeparate(TIFFImageIter*, void *udata, uint32, uint32); static const char photoTag[] = "PhotometricInterpretation"; static int isCCITTCompression(TIFF* tif) { uint16 compress; TIFFGetField(tif, TIFFTAG_COMPRESSION, &compress); return (compress == COMPRESSION_CCITTFAX3 || compress == COMPRESSION_CCITTFAX4 || compress == COMPRESSION_CCITTRLE || compress == COMPRESSION_CCITTRLEW); } int TIFFImageIterBegin(TIFFImageIter* img, TIFF* tif, int stop, char emsg[1024]) { uint16* sampleinfo; uint16 extrasamples; uint16 planarconfig; int colorchannels; img->tif = tif; img->stoponerr = stop; TIFFGetFieldDefaulted(tif, TIFFTAG_BITSPERSAMPLE, &img->bitspersample); img->alpha = 0; TIFFGetFieldDefaulted(tif, TIFFTAG_SAMPLESPERPIXEL, &img->samplesperpixel); TIFFGetFieldDefaulted(tif, TIFFTAG_EXTRASAMPLES, &extrasamples, &sampleinfo); if (extrasamples == 1) switch (sampleinfo[0]) { case EXTRASAMPLE_ASSOCALPHA: /* data is pre-multiplied */ case EXTRASAMPLE_UNASSALPHA: /* data is not pre-multiplied */ img->alpha = sampleinfo[0]; break; } colorchannels = img->samplesperpixel - extrasamples; TIFFGetFieldDefaulted(tif, TIFFTAG_PLANARCONFIG, &planarconfig); if (!TIFFGetField(tif, TIFFTAG_PHOTOMETRIC, &img->photometric)) { switch (colorchannels) { case 1: if (isCCITTCompression(tif)) img->photometric = PHOTOMETRIC_MINISWHITE; else img->photometric = PHOTOMETRIC_MINISBLACK; break; case 3: img->photometric = PHOTOMETRIC_RGB; break; default: sprintf(emsg, "Missing needed %s tag", photoTag); return (0); } } switch (img->photometric) { case PHOTOMETRIC_PALETTE: if (!TIFFGetField(tif, TIFFTAG_COLORMAP, &img->redcmap, &img->greencmap, &img->bluecmap)) { TIFFErrorExt(tif->tif_clientdata, TIFFFileName(tif), "Missing required \"Colormap\" tag"); return (0); } /* fall thru... */ case PHOTOMETRIC_MINISWHITE: case PHOTOMETRIC_MINISBLACK: /* This should work now so skip the check - BSR if (planarconfig == PLANARCONFIG_CONTIG && img->samplesperpixel != 1) { sprintf(emsg, "Sorry, can not handle contiguous data with %s=%d, and %s=%d", photoTag, img->photometric, "Samples/pixel", img->samplesperpixel); return (0); } */ break; case PHOTOMETRIC_YCBCR: if (planarconfig != PLANARCONFIG_CONTIG) { sprintf(emsg, "Sorry, can not handle YCbCr images with %s=%d", "Planarconfiguration", planarconfig); return (0); } /* It would probably be nice to have a reality check here. */ { uint16 compress; TIFFGetField(tif, TIFFTAG_COMPRESSION, &compress); if (compress == COMPRESSION_JPEG && planarconfig == PLANARCONFIG_CONTIG) { /* can rely on libjpeg to convert to RGB */ /* XXX should restore current state on exit */ TIFFSetField(tif, TIFFTAG_JPEGCOLORMODE, JPEGCOLORMODE_RGB); img->photometric = PHOTOMETRIC_RGB; } } break; case PHOTOMETRIC_RGB: if (colorchannels < 3) { sprintf(emsg, "Sorry, can not handle RGB image with %s=%d", "Color channels", colorchannels); return (0); } break; case PHOTOMETRIC_SEPARATED: { uint16 inkset; TIFFGetFieldDefaulted(tif, TIFFTAG_INKSET, &inkset); if (inkset != INKSET_CMYK) { sprintf(emsg, "Sorry, can not handle separated image with %s=%d", "InkSet", inkset); return (0); } if (img->samplesperpixel != 4) { sprintf(emsg, "Sorry, can not handle separated image with %s=%d", "Samples/pixel", img->samplesperpixel); return (0); } break; } default: sprintf(emsg, "Sorry, can not handle image with %s=%d", photoTag, img->photometric); return (0); } TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &img->width); TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &img->height); TIFFGetFieldDefaulted(tif, TIFFTAG_ORIENTATION, &img->orientation); switch (img->orientation) { case ORIENTATION_BOTRIGHT: case ORIENTATION_RIGHTBOT: /* XXX */ case ORIENTATION_LEFTBOT: /* XXX */ TIFFWarning(TIFFFileName(tif), "using bottom-left orientation"); img->orientation = ORIENTATION_BOTLEFT; /* fall thru... */ case ORIENTATION_BOTLEFT: break; case ORIENTATION_TOPRIGHT: case ORIENTATION_RIGHTTOP: /* XXX */ case ORIENTATION_LEFTTOP: /* XXX */ default: TIFFWarning(TIFFFileName(tif), "using top-left orientation"); img->orientation = ORIENTATION_TOPLEFT; /* fall thru... */ case ORIENTATION_TOPLEFT: break; } img->isContig = !(planarconfig == PLANARCONFIG_SEPARATE && colorchannels > 1); if (img->isContig) { img->get = TIFFIsTiled(tif) ?

This code was basically written by ripping of the TIFFWriteDirectory() code and generalizing it, using RPS's TIFFWritePliIfd() code for inspiration. My original goal was to make this code general enough that the original TIFFWriteDirectory() could be rewritten to just call this function with the appropriate field and field-accessing arguments. However, now I realize that there's a lot of code that gets executed for the main, standard TIFF directories that does not apply to special private subdirectories, so such a reimplementation for the sake of eliminating redundant or duplicate code is probably not possible, unless we also pass in a Main flag to indiciate which type of handling to do, which would be kind of a hack. I've marked those places where I changed or ripped out code which would have to be re-inserted to generalize this function. If it can be done in a clean and graceful way, it would be a great way to generalize the TIFF library. Otherwise, I'll just leave this code here where it duplicates but remains on top of and hopefully mostly independent of the main TIFF library. The caller will probably want to free the sub directory structure after returning from this call, since otherwise once written out, the user is likely to forget about it and leave data lying around. */ toff_t TIFFWritePrivateDataSubDirectory(TIFF* tif, uint32 pdir_fieldsset[], int pdir_fields_last, TIFFFieldInfo *field_info, int (*getFieldFn)(TIFF *tif, ttag_t tag, ...)) { uint16 dircount; uint32 diroff, nextdiroff; ttag_t tag; uint32 nfields; tsize_t dirsize; char* data; TIFFDirEntry* dir; u_long b, *fields, fields_size; toff_t directory_offset; TIFFFieldInfo* fip; /* * Deleted out all of the encoder flushing and such code from here - * not necessary for subdirectories. */ /* Finish writing out any image data. */ TIFFFlushData(tif); /* * Size the directory so that we can calculate * offsets for the data items that aren't kept * in-place in each field. */ nfields = 0; for (b = 0; b <= pdir_fields_last; b++) if (FieldSet(pdir_fieldsset, b)) /* Deleted code to make size of first 4 tags 2 instead of 1. */ nfields += 1; dirsize = nfields * sizeof (TIFFDirEntry); data = (char*) _TIFFmalloc(dirsize); if (data == NULL) { TIFFErrorExt(tif->tif_clientdata, tif->tif_name, "Cannot write private subdirectory, out of space"); return (0); } /* * Place directory in data section of the file.

Some applications can take advantage of these overviews to accelerate overview display performance of large rasters. This release of addtiffo is primarily intended for compatibility testing with applications, and to see if there is interest in a cleaner release of the capability ... perhaps incorporation into the libtiff tools distribution. Please feel free to contact me with questions, or problems. warmerda@home.com http://home.gdal.org/~warmerda/ Usage ----- Usage: addtiffo [-r {average/nearest} [-subifd] tiff_filename [resolution_reductions] Example: % addtiffo abc.tif 2 4 8 16 The numeric arguments are the list of reduction factors to generate. In this example a 1/2, 1/4 1/8 and 1/16 Limitations ----------- See tif_overview.cpp for up to date details. o Currently only images with bits_per_sample of a multiple of eight will work. o The code will attempt to use the same kind of compression, photometric interpretation, and organization as the source image, but it doesn't copy geotiff tags to the reduced resolution images. o Reduced resolution overviews for multi-sample files will currently always be generated as PLANARCONFIG_SEPARATE. This could be fixed reasonable easily if needed to improve compatibility with other packages. Many don't properly support PLANARCONFIG_SEPARATE. o Overviews are always written as appended IFDs, rather than using the ``tree of tree's'' approach using the SUBIFD tag. I wanted to implement both, but it isn't currently easy to add a SUBIFD tag to an existing main tiff IFD with libtiff. I hope to try this again later. TIFF File Tags -------------- The results of running addtiffo on a 1024x1024 tiled greyscale file with the arguments ``2 4 8 16'' is to add four additional TIFF directories appended on the file with the SUBFILETYPE flag to 0x1 indicating the extra items are reduced resolution images. The tiffinfo output of such a file might look like this: TIFF Directory at offset 0x118008 Image Width: 1024 Image Length: 1024 Tile Width: 256 Tile Length: 112 Bits/Sample: 8 Compression Scheme: none Photometric Interpretation: min-is-black Samples/Pixel: 1 Planar Configuration: single image plane TIFF Directory at offset 0x15e1d2 Subfile Type: reduced-resolution image (1 = 0x1) Image Width: 512 Image Length: 512 Tile Width: 256 Tile Length: 112 Bits/Sample: 8 Compression Scheme: none Photometric Interpretation: min-is-black Samples/Pixel: 1 Planar Configuration: separate image planes TIFF Directory at offset 0x1732b8 Subfile Type: reduced-resolution image (1 = 0x1) Image Width: 256 Image Length: 256 Tile Width: 256 Tile Length: 112 Bits/Sample: 8 Compression Scheme: none Photometric Interpretation: min-is-black Samples/Pixel: 1 Planar Configuration: separate image planes TIFF Directory at offset 0x17a366 Subfile Type: reduced-resolution image (1 = 0x1) Image Width: 128 Image Length: 128 Tile Width: 128 Tile Length: 112 Bits/Sample: 8 Compression Scheme: none Photometric Interpretation: min-is-black Samples/Pixel: 1 Planar Configuration: separate image planes TIFF Directory at offset 0x17b40c Subfile Type: reduced-resolution image (1 = 0x1) Image Width: 64 Image Length: 64 Tile Width: 64 Tile Length: 64 Bits/Sample: 8 Compression Scheme: none Photometric Interpretation: min-is-black Samples/Pixel: 1 Planar Configuration: separate image planes Building -------- You will need a C compiler. You will need to have libtiff already built and installed. The provided Makefile should work on most Unix systems. A similar file will be needed for Windows, but is not provided. The CFLAGS and LIBS macros in the Makefile will have to be updated to point to the correct location of the libtiff include files, and library. Credits ------- o Intergraph Corporation for partially funding the work. o Global Geomatics for partially funding reorganization of the overview building ability as a separate utility. o Orrin Long, and Ed Grissom of Intergraph for explaining what needed to be done. o Max Martinez of Erdas for his discussion of external overviews. o Atlantis Scientific who supported adding averaging, and some other generalizations. o Frank Warmerdam for writing the bulk of the code. o Sam Leffler since this only exists because of his libtiff. tiff-4.0.3/contrib/addtiffo/tif_ovrcache.c0000644000212300117540000003225111403511023015400 00000000000000/****************************************************************************** * $Id: tif_ovrcache.c,v 1.9 2010-06-08 18:55:15 bfriesen Exp $ * * Project: TIFF Overview Builder * Purpose: Library functions to maintain two rows of tiles or two strips * of data for output overviews as an output cache. * Author: Frank Warmerdam, warmerdam@pobox.com * ****************************************************************************** * Copyright (c) 2000, Frank Warmerdam * * Permission is hereby granted, free of charge, to any person obtaining a * copy of this software and associated documentation files (the "Software"), * to deal in the Software without restriction, including without limitation * the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the * Software is furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included * in all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

We have used libtiff to create and convert TIFF images of financial documents which are sent from and to major document processing systems in Sweden and Denmark. I would like to express my deep gratitude to yourself and Sillicon Graphics for making this excellent library available for public use. There is obviously a lot of work that has gone in to libtiff and the quality of the code and documentation is an example to others. One thing that libtiff did not do was work on a memory area rather than files. In my applications I had already read a TIFF or other format file in to memory and did not want to waste I/O writing it out again for libtiff's benefit. I therefore constructed a set of functions to pass up to TIFFClientOpen to simulate a file in memory. I have attached my mfs (memory file system) source code for you to use or junk, as you see fit. :-) Once again, thanks very much for making my life simpler. Best Regards, Mike Johnson. tiff-4.0.3/contrib/win_dib/0000755000212300117540000000000012027361331012520 500000000000000tiff-4.0.3/contrib/win_dib/README.Tiffile0000644000212300117540000000232507501540120014677 00000000000000Frank, I attached a file that uses RGBA interface (tif_getimage.c) to read a tiff file and convert to a DIB. It's advantage is that it is easy to read *any* tiff file suported by libtiff and easily convert it to a DIB. The disadvantage is that bilevel (B&W) bitmaps (and all other non-rgba images) are also converted to RGBA, thus taking up 32x as much memory as needed (4 bytes per pixel, rather than 1 bit). I read tiff files, but don't need to write them. And my files are typically small, so the overhead is mostly inconsequential. But for bilevel images, I overrode the get() and put() routines of the RGBA interface to just copy the data from the input raster to the output raster, rather than expanding out to full 32 bit format. It would be nice if there were a simple way to handle all palletized images, but that would take more custom routines, and it's not that important to me. Usage: m_pDIB = (PBITMAPINFOHEADER)::ReadTIFF(pathName); if (m_pDIB != 0) { m_format = IMAGETYPE_TIF; } This is intended as Win32, but the modifications for new get() and put() routines may be independent of platform. Thanks for your work supporting the forum and the library!

Here is some information that may help someone. I build the library under Windows 95 as a 32-bit library. The contribution of Scott Wagner (tif_win32.c) worked fine, but the makefile "makefile.msc" was unsable because it was written for DOS or Windows 3.1 and all the files names are limited to 8 characters. Here is the makefile I used : makefile.w95 Also, I had to disable fax3 support because I wasn't able to build (as it is) the tool "mkg3states" to generate the include file "g3states.h". This source file must be modify to be build under Windows 95. To build the library under Windows 95 with Visual C++ 2.0, I had to : - undefine CCITT_SUPPORT in "tiffconf.h" - create the file version.h with this line : #define VERSION "3.4beta024" - build the makefile "makefile.w95" I also join the source file "tif2dib.c" that I created, it contain the function LoadTIFFinDIB that load a TIFF file and build a memory DIB with it and return the HANDLE (HDIB) of the memory bloc containing this DIB. Since DIB is the "natural" bitmap format for Windows 3.1, 95 and NT, this function sould be usefull for some Windows 95 (or NT) developer. Sorry for my approximate english ...

The described approach requires internal knowledge of the libtiff API and tends to be very fragile in the face of libtiff upgrades. Please read over the html/addingtags.html in preference to the below described approach. ================================== Client module for adding to LIBTIFF tagset ------------------------------------------- Author: Niles Ritter In the past, users of the "libtiff" package had to modify the source code of the library if they required additional private tags or codes not recognized by libtiff. Thus, whenever a new revision of libtiff came out the client would have to perform modifications to six or seven different files to re-install their tags. The latest versions of libtiff now provide client software new routines, giving them the opportunity to install private extensions at runtime, rather than compile-time. This means that the client may encapsulate all of their private tags into a separate module, which need only be recompiled when new versions of libtiff are released; no manual editing of files is required. How it works ------------ The mechanism for overriding the tag access has been enabled with a single new routine, which has the following calling sequence: TIFFExtendProc old_extender; old_extender = TIFFSetTagExtender(tag_extender); which must be called prior to opening or creating TIFF files. This routine sets a static pointer to the user-specified function , which in turn is called by TIFFDefaultDirectory(), just after the usual TIFFSetField() and TIFFGetField() methods are defined, and just before the compression tag is set. It also returns a pointer to the previously-defined value of the tag-extender, so that multiple clients may be installed. The TIFFExtendProc method that you define should be used to override the TIFF file's "vsetfield" and "vgetfield" methods, so that you can trap your new, private tags, and install their values into a private directory structure. For your convienience, a new pointer has also been added to the "TIFF" file structure: tidata_t tif_clientdir; /* client TIFF directory */ into which you may install whatever private directory structures you like. You should also override the tag-printing method from within your "vsetfield" method, to permit the symbolic printing of your new tags. Example Client Code: -------------------- An example module has been provided as a template for installing your own tags into a client tag extender. The module is called "xtif_dir.c", and defines all of the interface routines, tag field access, tag printing, etc. for most purpose. To see how the client module operates, there are three "fake" tags currently installed. If you use the existing makefile you can build them with: make all -f Makefile.gcc !or Makefile.mpw maketif listtif This will build two example programs called "maketif" and "listtif" and then run them. These programs do nothing more than create a small file called "newtif.tif", install the fake tags, and then list them out using TIFFPrintDirectory(). Installing Private Tags ----------------------- To use this module for installing your own tags, edit each of the files xtif_dir.c xtiffio.h xtiffiop.h and search for the string "XXX". At these locations the comments will direct you how to install your own tag values, define their types, etc. Three examples tags are currently installed, demonstrating how to implement multi-valued tags, single-valued tags, and ASCII tags. The examples are not valid, registered tags, so you must replace them with your own. To test the routines, also edit the test programs "maketif.c" and "listtif.c" and replace the portions of the code that set the private tag values and list them. Once you have edited these files, you may build the client module with the Makefile provided, and run the test programs. To use these files in your own code, the "xtif_dir.c" module defines replacement routines for the standard "TIFFOpen()" "TIFFFdOpen", and "TIFFClose()" routines, called XTIFFOpen, XTIFFFdOpen and XTIFFClose. You must use these routines in order to have the extended tag handlers installed. Once installed, the standard TIFFGetField() and TIFFSetField routines may be used as before. Adding Extended Tags to "tools" ------------------------------- To create an extended-tag savvy "tiffinfo" program or other utility, you may simply recompile and link the tools to your "libxtiff" library, adding -DTIFFOpen=XTIFFOpen -DTIFFClose=XTIFFClose -DTIFFFdOpen=XTIFFFdOpen to the compile statement.

The implementation is an adaptor class, which takes any C++ stream from the user and in return it deposits i/o operation method pointers (e.g. read, write, seek and close) into the tiff's library client state. The class TiffStream has an overloaded factory method - makeFileStream - which takes the C++ stream as an argument, calls TIFFClientOpen and returns a tiff handle. The class retains the tiff handle in its local state and provides a helper function (getTiffHandle) to query the handle at any time. Additional helper method - getStreamSize - provides the stream size to the user. The implementation assumes client responsibility to delete the stream object. The class calls TIFFClose at destruction time. Attached are a definition (tiffstream.h) and an implementation (tiffstream.cpp) files of the TiffStream class. No changes are required to the tiff core piece and the class sits on top of the library. The code is fairly tested at this point and is used internally in Shutterfly imaging software. The code is portable across WindowsNT/Linux/Solaris. We at Shutterfly believe this software has benefits to the larger community of tiff library users and would like to contribute this software to be part of the tiff distributed package. Let me know of any issue.

Again, this is for * black and white; I've not tried it with color. * -- * Lou Steinberg * * [2] Color Image Quantization for Frame Buffer Display, Paul Heckbert, * Siggraph '82 proceedings, pp. 297-307 */ #include "tif_config.h" #include #include #include #ifdef HAVE_UNISTD_H # include #endif #ifdef NEED_LIBPORT # include "libport.h" #endif #include "tiffio.h" #define MAX_CMAP_SIZE 256 #define streq(a,b) (strcmp(a,b) == 0) #define strneq(a,b,n) (strncmp(a,b,n) == 0) #define COLOR_DEPTH 8 #define MAX_COLOR 256 #define B_DEPTH 5 /* # bits/pixel to use */ #define B_LEN (1L< MAX_CMAP_SIZE) { fprintf(stderr, "-c: colormap too big, max %d\n", MAX_CMAP_SIZE);

Replaced original PlaceImage function with several * new functions that make support for multiple output pages * from a single image easier to understand. Added additional * warning messages for incompatible command line options. * Add new command line options to specify PageOrientation * Document Structuring Comment for landscape or portrait * and code to determine the values from ouput width and height * if not specified on the command line. * Add new command line option to specify document creator * as an alterntive to the string "tiff2ps" following model * of patch submitted by Thomas Jarosch for specifiying a * document title which is also supported now. * * 2009-Feb-11 * Richard Nolde: Added support for rotations of 90, 180, 270 * and auto using -r <90|180|270|auto>. Auto picks the best * fit for the image on the specified paper size (eg portrait * or landscape) if -h or -w is specified. Rotation is in * degrees counterclockwise since that is how Postscript does * it. The auto opption rotates the image 90 degrees ccw to * produce landscape if that is a better fit than portait. * * Cleaned up code in TIFF2PS and broke into smaller functions * to simplify rotations. * * Identified incompatible options and returned errors, eg * -i for imagemask operator is only available for Level2 or * Level3 Postscript in the current implmentation since there * is a difference in the way the operands are called for Level1 * and there is no function to provide the Level1 version. * -H was not handled properly if -h and/or -w were specified. * It should only clip the masked images if the scaled image * exceeds the maxPageHeight specified with -H. * * New design allows for all of the following combinations: * Conversion of TIFF to Postscript with optional rotations * of 90, 180, 270, or auto degrees counterclockwise * Conversion of TIFF to Postscript with entire image scaled * to maximum of values spedified with -h or -w while * maintaining aspect ratio. Same rotations apply. * Conversion of TIFF to Postscript with clipping of output * viewport to height specified with -H, producing multiple * pages at this height and original width as needed. * Same rotations apply. * Conversion of TIFF to Postscript with image scaled to * maximum specified by -h and -w and the resulting scaled * image is presented in an output viewport clipped by -H height. * The same rotations apply. * * Added maxPageWidth option using -W flag. MaxPageHeight and * MaxPageWidth are mutually exclusive since the aspect ratio * cannot be maintained if you set both. * Rewrote PlaceImage to allow maxPageHeight and maxPageWidth * options to work with values smaller or larger than the * physical paper size and still preserve the aspect ratio. * This is accomplished by creating multiple pages across * as well as down if need be. * * 2001-Mar-21 * I (Bruce A. Mallett) added this revision history comment ;) * * Fixed PS_Lvl2page() code which outputs non-ASCII85 raw * data. Moved test for when to output a line break to * *after* the output of a character. This just serves * to fix an eye-nuisance where the first line of raw * data was one character shorter than subsequent lines. * * Added an experimental ASCII85 encoder which can be used * only when there is a single buffer of bytes to be encoded. * This version is much faster at encoding a straight-line * buffer of data because it can avoid a lot of the loop * overhead of the byte-by-byte version. To use this version * you need to define EXP_ASCII85ENCODER (experimental ...). * * Added bug fix given by Michael Schmidt to PS_Lvl2page() * in which an end-of-data marker ('>') was not being output * when producing non-ASCII85 encoded PostScript Level 2 * data. * * Fixed PS_Lvl2colorspace() so that it no longer assumes that * a TIFF having more than 2 planes is a CMYK. This routine * no longer looks at the samples per pixel but instead looks * at the "photometric" value. This change allows support of * CMYK TIFFs. * * Modified the PostScript L2 imaging loop so as to test if * the input stream is still open before attempting to do a * flushfile on it. This was done because some RIPs close * the stream after doing the image operation. * * Got rid of the realloc() being done inside a loop in the * PSRawDataBW() routine. The code now walks through the * byte-size array outside the loop to determine the largest * size memory block that will be needed. * * Added "-m" switch to ask tiff2ps to, where possible, use the * "imagemask" operator instead of the "image" operator. * * Added the "-i #" switch to allow interpolation to be disabled. * * Unrolled a loop or two to improve performance. */ /* * Define EXP_ASCII85ENCODER if you want to use an experimental * version of the ASCII85 encoding routine. The advantage of * using this routine is that tiff2ps will convert to ASCII85 * encoding at between 3 and 4 times the speed as compared to * using the old (non-experimental) encoder. The disadvantage * is that you will be using a new (and unproven) encoding * routine.

The program converts one TIFF file to one PDF file, including multiple page TIFF files, tiled TIFF files, black and white. grayscale, and color TIFF files that contain data of TIFF photometric interpretations of bilevel, grayscale, RGB, YCbCr, CMYK separation, and ICC L*a*b* as supported by libtiff and PDF. If you have multiple TIFF files to convert into one PDF file then use tiffcp or other program to concatenate the files into a multiple page TIFF file. If the input TIFF file is of huge dimensions (greater than 10000 pixels height or width) convert the input image to a tiled TIFF if it is not already. The standard output is standard output. Set the output file name with the "-o output.pdf" option. All black and white files are compressed into a single strip CCITT G4 Fax compressed PDF, unless tiled, where tiled black and white images are compressed into tiled CCITT G4 Fax compressed PDF, libtiff CCITT support is assumed. Color and grayscale data can be compressed using either JPEG compression, ITU-T T.81, or Zip/Deflate LZ77 compression, per PNG 1.2 and RFC 1951. Set the compression type using the -j or -z options. JPEG compression support requires that libtiff be configured with JPEG support, and Zip/Deflate compression support requires that libtiff is configured with Zip support, in tiffconf.h. Use only one or the other of -j and -z. The -q option sets the image compression quality, that is 1-100 with libjpeg JPEG compression and one of 1, 10, 11, 12, 13, 14, or 15 for PNG group compression predictor methods, add 100, 200, ..., 900 to set zlib compression quality 1-9. PNG Group differencing predictor methods are not currently implemented. If the input TIFF contains single strip CCITT G4 Fax compressed information, then that is written to the PDF file without transcoding, unless the options of no compression and no passthrough are set, -d and -n. If the input TIFF contains JPEG or single strip Zip/Deflate compressed information, and they are configured, then that is written to the PDF file without transcoding, unless the options of no compression and no passthrough are set. The default page size upon which the TIFF image is placed is determined by the resolution and extent of the image data. Default values for the TIFF image resolution can be set using the -x and -y options. The page size can be set using the -p option for paper size, or -w and -l for paper width and length, then each page of the TIFF image is centered on its page. The distance unit for default resolution and page width and length can be set by the -u option, the default unit is inch. Various items of the output document information can be set with the -e, -c, -a, -t, -s, and -k tags. Setting the argument of the option to "" for these tags causes the relevant document information field to be not written. Some of the document information values otherwise get their information from the input TIFF image, the software, author, document name, and image description. The output PDF file conforms to the PDF 1.1 specification or PDF 1.2 if using Zip/Deflate compression. The Portable Document Format (PDF) specification is copyrighted by Adobe Systems, Incorporated. Todos derechos reservados. Here is a listing of the usage example and the options to the tiff2pdf program that is part of the libtiff distribution. Options followed by a colon have a required argument. usage: tiff2pdf [options] input.tif options: -o: output to file name -j: compress with JPEG (requires libjpeg configured with libtiff) -z: compress with Zip/Deflate (requires zlib configured with libtiff) -q: compression quality -n: no compressed data passthrough -d: do not compress (decompress) -i: invert colors -u: set distance unit, 'i' for inch, 'm' for centimeter -x: set x resolution default -y: set y resolution default -w: width in units -l: length in units -r: 'd' for resolution default, 'o' for resolution override -p: paper size, eg "letter", "legal", "a4" -F: make the tiff fill the PDF page -f: set pdf "fit window" user preference -b: set PDF "Interpolate" user preference -e: date, overrides image or current date/time default, YYYYMMDDHHMMSS -c: creator, overrides image software default -a: author, overrides image artist default -t: title, overrides image document name default -s: subject, overrides image image description default -k: keywords -h: usage examples: tiff2pdf -o output.pdf input.tiff The above example would generate the file output.pdf from input.tiff. tiff2pdf input.tiff The above example would generate PDF output from input.tiff and write it to standard output. tiff2pdf -j -p letter -o output.pdf input.tiff The above example would generate the file output.pdf from input.tiff, putting the image pages on a letter sized page, compressing the output with JPEG.

Make sure that you have current FSF releases of autoconf, automake, and libtool packages installed under a common installation prefix and that these tools are in your executable search path prior to any other installed versions. Versions delivered with Linux may be altered so it is best to install official FSF releases. GNU 'm4' 1.4.16 is needed in order to avoid bugs in m4. These packages may be downloaded from the following ftp locations: autoconf - ftp://ftp.gnu.org/pub/gnu/autoconf automake - ftp://ftp.gnu.org/pub/gnu/automake libtool - ftp://ftp.gnu.org/pub/gnu/libtool m4 - ftp://ftp.gnu.org/pub/gnu/m4 Release builds should only be done on a system with a functioning and correctly set system clock and on a filesystem which accurately records file update times. Use of GNU make is recommended. 1. Commit any unsaved changes. 2. Create html/vX.X.html. Take ChangeLog entries and html-ify in there. Easist thing to do is take html/vX.(X-1).html and use it as a template. Add that file to the list of EXTRA_DIST files in the html/Makefile.am. 3. Update html/index.html to refer to this new page as the current release. 4. Increment the release version in configure.ac. Put 'alpha' or 'beta' after the version, if applicable. For example: 4.0.0 or 4.0.0beta7 Version should be updated in two places: in the second argument of the AC_INIT macro and in LIBTIFF_xxx_VERSION variables. 5. Update library ELF versioning in configure.ac (LIBTIFF_CURRENT, LIBTIFF_REVISION, and LIBTIFF_AGE). These numbers have nothing to do with the libtiff release version numbers. Note that as of libtiff 4.X, proper ELF versioning is used so please follow the rules listed in configure.ac. At a bare minimum, you should increment LIBTIFF_REVISION for each release so that installed library files don't overwrite existing files. If APIs have been added, removed, or interface structures have changed, then more care is required. 6. Add an entry to Changelog similar to: * libtiff 4.0.0 released. 7. In the source tree do ./autogen.sh This step may be skipped if you have already been using a maintainer build with current autoconf, automake, and libtool packages. It is only needed when updating tool versions. 8. It is recommended (but not required) to build outside of the source tree so that the source tree is kept in a pristine state. This also allows sharing the source directory on several networked systems. For example: mkdir libtiff-build cd libtiff-build /path/to/libtiff/configure --enable-maintainer-mode otherwise do ./configure --enable-maintainer-mode 9. In the build tree do make release This will update "RELEASE-DATE", "VERSION", and libtiff/tiffvers.h in the source tree. 10. In the source tree, verify that the version info in RELEASE-DATE, VERSION and libtiff/tiffvers.h is right. 11. In the build tree do make make distcheck If 'make distcheck' fails, then correct any issues until it succeeds. Two files with names tiff-version.tar.gz and tiff-version.zip will be created in the top level build directory. 12. In the source tree do 'cvs commit'. 13. In the source tree do cvs tag Release-v4-0-0 (or the appropriate name for the release) 14. Copy release packages from the build tree to the ftp.remotesensing.org ftp site. scp tiff-*.tar.gz tiff-*.zip \ warmerdam@upload.osgeo.org:/osgeo/download/libtiff 15. Announce to list, tiff@lists.maptools.org 16. Update libtiff page on freshmeat with new version announcement. tiff-4.0.3/ChangeLog0000644000212300117540000061526612027361063011161 000000000000002012-09-22 Bob Friesenhahn * libtiff 4.0.3 released. 2012-09-20 Bob Friesenhahn * Makefile.am: Update to Automake 1.12.4 2012-08-19 Bob Friesenhahn * Makefile.in: Update to Automake 1.12.3 * libtiff{tiff.h, tif_print.c, tif_dirinfo.c, tif_dirread.c}: Add some TIFF/FX support in libtiff. Add the tag definitions to tiff.h. Add the related TIFF field definitions to tif_dirinfo.c, and also fixes an error in a comment. Adds the photometric values to tif_print.c, and fixes a bug. These changes are by Steve Underwood. 2012-08-13 Frank Warmerdam * libtiff/tif_write.c: Fix bug rewriting image tiles in a compressed file: http://trac.osgeo.org/gdal/ticket/4771 2012-08-02 Frank Warmerdam * libtiff/tif_dirread.c: report error in case of mismatch value counts for tags (ie. DotRange). 2012-07-26 Tom Lane * libtiff/{tiffio.h, tif_dirinfo.c, libtiff.def}: Add six new functions TIFFFieldTag(), TIFFFieldName(), TIFFFieldDataType(), TIFFFieldPassCount(), TIFFFieldReadCount(), TIFFFieldWriteCount() as external accessors for the opaque type TIFFField. * tools/tiffset.c: Make tiffset use the above functions instead of relying on library private headers. 2012-07-19 Tom Lane * tools/tiff2pdf.c: Fix two places where t2p_error didn't get set after a malloc failure. No crash risk AFAICS, but the program might not report exit code 1 as desired. h/t mancha@mac.hush.com 2012-07-18 Tom Lane * tools/tiff2pdf.c: Fail when TIFFSetDirectory() fails. This prevents core dumps or perhaps even arbitrary code execution when processing a corrupt input file (CVE-2012-3401). 2012-07-06 Bob Friesenhahn * test/raw_decode.c (main): Test fixes to work with IJG JPEG 7+. IJG JPEG 7+ uses a different upsampling algorithm which produces different numeric results. * libtiff/tif_jpeg.c (JPEGPreDecode): Patch from Even Rouault to work with IJG JPEG 7+. 2012-07-04 Bob Friesenhahn * test/raw_decode.c: Add changes so that test can run with build directory outside of source directory. 2012-07-02 Frank Warmerdam * libtiff/tif_jpeg.c: Fix handling when writing RGBA jpeg compressed imagery (http://trac.osgeo.org/gdal/ticket/4732) 2012-06-20 Frank Warmerdam * libtiff/tif_fax3.c: fix memory initialization of runs, only partly done. * libtiff/tif_pixarlog.c: Make sure tbuf is large enough for one full "stride" past the end. 2012-06-19 Frank Warmerdam * libtiff/tif_packbits.c: fix read past end of data buffer. 2012-06-15 Frank Warmerdam * libtiff 4.0.2 released. * tools/tif2pdf.c, tools/tifdump.c: avoid unitialized variable warnings with clang. 2012-06-15 Tom Lane * tools/tiff2pdf.c: Defend against integer overflows while calculating required buffer sizes (CVE-2012-2113). 2012-06-12 Frank Warmerdam * libtiff/tif_print.c: Be careful about printing corrupt inknames. * libtiff/tif_fax3.c: Ensure runs array is initialized to zeros. 2012-06-07 Frank Warmerdam * libtiff/tif_print.c: avoid pretty printing other fields when we don't have the proper amount and type of data or if the field is actually autodefined. 2012-06-05 Frank Warmerdam * libtiff/tif_tile.c, libtiff/tif_strip.c: Ensure that illegal ycbcrsubsampling values result in a runtime error, not just an assertion. * tests/custom_dir.c: Add testing of EXIF and custom directory reading and writing. * libtiff/tif_dir.c, libtiff/tiffio.h: Add TIFFCreateCustomDirectory() and TIFFCreateEXIFDirectory() functions. * libtiff/tif_dir.c, tif_print.c : Remove FIELD_CUSTOM handling for PAGENUMBER, HALFTONEHINTS, and YCBCRSUBSAMPLING. Implement DOTRANGE differently. This is to avoid using special TIFFGetField/TIFFSetField rules for these fields in non-image directories (like EXIF). 2012-06-04 Frank Warmerdam * libtiff/tif_jpeg.c: Remove code for fixing up h_sampling and v_sampling in JPEGPreDecode(). If a fixup will be done it needs to be done sooner in JPEGFixupTagsSubsampling() or else buffer sized may be wrong. 2012-06-01 Frank Warmerdam * tools/tiffinfo.c: Do not try to read image data in EXIF directories. * libtiff/tif_getimage.c: added support for _SEPARATED CMYK images. http://bugzilla.maptools.org/show_bug.cgi?id=2379 * libtiff/tif_unix.c: use strerror() to return a more specific error message on failed open. http://bugzilla.maptools.org/show_bug.cgi?id=2341 * libtiff/tif_jpeg.c: Fix JPEGDecodeRaw() bugs. http://bugzilla.maptools.org/show_bug.cgi?id=2386 * tests/decode_raw.c, tests/images/quad-tile.jpg.tiff: add limited support for testing jpeg in tiff image decoding including the "raw" decode interface. 2012-05-31 Frank Warmerdam * libtiff/tif_jpeg.c: avoid overrunning the end of the output buffer in JPEGDecodeRaw() - mostly likely to occur when there is confusion about sampling values. * libtiff/tif_read.c: Make sure tif_rawdatasize is cleared when tif_rawdata is freed. * libtiff/tif_getimage.c: Add support for greyscale+alpha c/o Jérémie Laval. http://bugzilla.maptools.org/show_bug.cgi?id=2398 2012-05-29 Frank Warmerdam * libtiff/tif_dir.c: avoid using specific set/get logic to process fields in custom directories, like EXIF directories. This fixes problems like a tag "320" existing in a custom directory getting processed as if it were a colormap when it isn't really. Damn the wide variety of argument formulations to get/set functions for different tags! * libtiff/tif_dir.c: Ensure that we keep track of when tif_rawdata is a pointer into an mmap()ed file via TIFF_BUFFERMMAP flag. 2012-05-24 Frank Warmerdam * libtiff/tif_pixarlog.c: Allocate working buffer one word larger since we "forward accumulate" and overwrite the end by one word in at least some cases. 2012-05-23 Frank Warmerdam * libtiff/tif_pixarlog.c: avoid accessing out of the lookup arrays for out of range inputs. * tools/tiffinfo.c: initialize h=0 to avoid undefined variable for degenerate files. * libtiff/tif_ojpeg.c: if OJPEGWriteHeader() fails once do not bother trying again on the same image. * libtiff/tif_ojpeg.c: make things more resilient in the face of files without stripbytecounts or stripoffsets or where loading these fails. * libtiff/tif_print.c: be careful about whether min/max values are singular or one per sample. * libtiff/tif_print.c: Avoid confusion about count size when printing custom fields. May affect things like ISOSpeedRatings. * libtiff/tif_dir.c: avoid one byte past end of ink names reading in some cases. 2012-05-19 Bob Friesenhahn * man/TIFFGetField.3tiff: Correct the 'count' field type in the example for how to retreive the value of unsupported tags. 2012-03-30 Frank Warmerdam * tif_getimage.c: Fix size overflow (zdi-can-1221,CVE-2012-1173) care of Tom Lane @ Red Hat. 2012-02-18 Bob Friesenhahn * libtiff 4.0.1 released. * Update automake used to 1.11.3. * libtiff/tiffio.h: Use double-underbar syntax in GCC printf attribute specification to lessen the risk of accidental macro substitution. Patch from Vincent Torri. 2012-01-31 Frank Warmerdam * libtiff/tif_dir.c, libtiff/tif_dirread.c: Extra caution around assumption tag fetching is always successful. * libtiff/tif_jpeg.c: Extra caution for case where sp is NULL. 2012-01-22 Bob Friesenhahn * configure.ac: Add support for using library symbol versioning on ELF systems with the GNU linker. Support is enabled via --enable-ld-version-script. Disabled by default for now until there is a decision for how to deploy a libtiff with versioned symbols after libtiff 4.0.0 was already released. 2011-12-22 Bob Friesenhahn * libtiff/tif_win32.c: Eliminate some minor 64-bit warnings in tif_win32.c. Patch by Edward Lam. * configure.ac: Add libtiff private dependency on -llzma for pkg-config. Patch by Mark Brand. Updated Automake to 1.11.2. 2011-12-21 Bob Friesenhahn * libtiff 4.0.0 released. 2011-12-08 Frank Warmerdam * libtiff/tif_dirread.c, libtiff/tif_read.c: more cautious checking of _TIFFFillStriles() results (#gdal 4372) 2011-12-07 Frank Warmerdam * libtiff/tif_dirread.c: fixes to deal with invalid files where _TIFFFillStriles() fails, and we try to chop up strips (gdal #4372) * libtiff/tif_dirread.c: fix error reporting when there is no tag information struct and name (gdal #4373) 2011-10-22 Bob Friesenhahn * Update GNU libtool to 2.4.2. * tools/tiffsplit.c (tiffcp): TIFFGetField count field should be uint32 type for TIFFTAG_JPEGTABLES. Patch by Christophe Deroulers. 2011-06-21 Frank Warmerdam * libtiff/libtiff.def: Restore TIFFMergeFieldInfo. 2011-05-31 Jim Meyering * libtiff/tif_dirread.c (TIFFFetchStripThing): Free "data" also upon failure to allocate "resizeddata". * tools/tiff2ps.c (PSDataBW): Zero buffer *after* checking for allocation failure, not before. * libtiff/tif_ojpeg.c: plug leaks on OJPEG read failure path * tools/rgb2ycbcr.c (cvtRaster): unchecked malloc * libtiff/tif_jpeg.c, tools/tiff2pdf.c, tools/tiff2ps.c: mark NULL-deref and possible overflow * tools/tiff2pdf.c: remove decl+set of set-but-not-used local, "written" * libtiff/tif_jpeg.c (JPEGInitializeLibJPEG): Remove declaration and set of otherwise unused local, data_is_empty. * libtiff/tif_jpeg.c (JPEGDecodeRaw) [JPEG_LIB_MK1_OR_12BIT]: Diagnose out-of-memory failure and return 0 rather than dereferencing NULL. 2011-05-24 Frank Warmerdam * libtiff/tif_dirread.c: produce special error message for zero tag directories instead of error out on the malloc(0) failure. 2011-05-16 Frank Warmerdam * libtiff/tif_dirinfo.c: Restore TIFFMergeFieldInfo() and related declarations as they are in active use by libraries such as libgeotiff, and work just fine. (#2315) 2011-04-20 Frank Warmerdam * libtiff/tif_dirinfo.c,tiffio.h: Remove the obsolete TIFFMergeFieldInfo/TIFFFindFieldInfo/TIFFFindFieldInfoByName API. http://bugzilla.maptools.org/show_bug.cgi?id=2315 * libtiff/libtiff.def: add some missing (64bit) APIs. http://bugzilla.maptools.org/show_bug.cgi?id=2316 2011-04-09 Bob Friesenhahn * libtiff 4.0.0beta7 released. 2011-04-09 Bob Friesenhahn * configure.ac: Should use AC_CANONICAL_HOST since host specifies the run-time target whereas target is used to specify the final output target if the package is a build tool (like a compiler), which libtiff is not. Resolves libtiff bug 2307 "Use AC_CANONICAL_HOST macro". 2011-04-02 Bob Friesenhahn * configure.ac: Support configuring TIFF_INT64_FORMAT and TIFF_UINT64_FORMAT appropriately for MinGW32. * tools/tiffdump.c (ReadDirectory): MinGW32 needs to use WIN32 printf conventions for 64-bit types because it uses the WIN32 CRT. * libtiff/{tif_dumpmode.c,tif_luv.c,tif_lzw.c,tif_print.c, tif_read.c,tif_strip.c,tif_thunder.c}: MinGW32 needs to use WIN32 printf conventions for 64-bit types because it uses the WIN32 CRT. * tools/tiff2pdf.c (t2p_write_pdf_string): Fix printf syntax not understood by WIN32 CRT. * libtiff/tif_ojpeg.c: Fixes to compile with MinGW32 GCC. * tools/fax2ps.c (main): Use tmpfile() rather than mkstemp() since it is much more portable. Tmpfile is included in ISO/IEC 9899:1990 and the WIN32 CRT. 2011-03-26 Frank Warmerdam * tools/tiffset.c: add -d and -sd switches to allow operation on a particular directory, not just the first (jef). 2011-03-21 Frank Warmerdam * libtiff/tif_thunder.c: Correct potential buffer overflow with thunder encoded files with wrong bitspersample set. The libtiff development team would like to thank Marin Barbella and TippingPoint's Zero Day Initiative for reporting this vulnerability (ZDI-CAN-1004, CVE-2011-1167). http://bugzilla.maptools.org/show_bug.cgi?id=2300 2011-03-10 Frank Warmerdam * libtiff/tif_fax3.h: Fix to last change allowing zero length runs at the start of a scanline - needed for legal cases. 2011-03-02 Frank Warmerdam * libtiff/tif_fax3.h: Protect against a fax VL(n) codeword commanding a move left. Without this, a malicious input file can generate an indefinitely large series of runs without a0 ever reaching the right margin, thus overrunning our buffer of run lengths. Per CVE-2011-0192. This is a modified version of a patch proposed by Drew Yao of Apple Product Security. It adds an unexpected() report, and disallows the equality case, since emitting a run without increasing a0 still allows buffer overrun. 2011-02-23 Frank Warmerdam * libtiff/tif_jpeg.c: avoid divide by zero in degenerate case (#2296) * tools/tiff2rgba.c: close source file on error to make leak detection easier. * libtiff/tif_getimage.c: avoid leaks if TIFFRGBAImageBegin() fails. http://bugzilla.maptools.org/show_bug.cgi?id=2295 2011-02-22 Frank Warmerdam * libtiff/tif_lzma.c: Maintain tif_rawcc/tif_rawcp (CHUNKY_STRING_READ _SUPPORT) 2011-02-18 Frank Warmerdam * configure.ac, configure: Added support for --enable-chunky-strip-read configure option to enable the experimental feature from a couple months ago for reading big strips in chunks. * configure.ac, tif_read.c, tif_readdir.c, tif_dir.h, tiffiop.h, tif_write.c, tif_print.c, tif_jpeg.c, tif_dirwrite.c, tif_write.c: Implement optional support for deferring the load of strip/tile offset and size tags for optimized scanning of directories. Enabled with the --enable-defer-strile-load configure option (DEFER_STRILE_LOAD #define in tif_config.h). 2011-02-11 Frank Warmerdam * libtiff/tif_print.c: remove unused variable. 2011-02-09 Frank Warmerdam * libtiff/tif_win32.c: avoid error/warning buffer overrun problem with non-console (popup message) builds on win32. http://bugzilla.maptools.org/show_bug.cgi?id=2293 2011-01-24 Olivier Paquet * libtiff/{tif_dir.{h,c}, tif_dirinfo.c, tif_dirread.c, tif_dirwrite.c, tif_print.c, tiff.h, tiffiop.h} : Added support for TIFFTAG_SMINSAMPLEVALUE and TIFFTAG_SMAXSAMPLEVALUE to have different values for each sample. Presents the min/max of all samples by default for compatibility. TIFFSetField/TIFFGetField can be made to handle those tags as arrays by changing the new TIFFTAG_PERSAMPLE pseudo tag. http://www.asmail.be/msg0055458208.html 2011-01-06 Frank Warmerdam * libtiff/tif_pixarlog.c: Note that tif_rawcc/tif_rawcp are not maintained. * libtiff/tif_zip.c: Maintain tif_rawcc/tif_rawcp when decoding for CHUNKY_STRIP_READ_SUPPORT. * libtiff/tif_jpeg.c: ensure that rawcc and rawcp are maintained during JPEGPreDecode and JPEGDecode calls. * libtiff/tif_read.c: larger read ahead for CHUNKY_STRIP_READ_SUPPORT, as compression formats like JPEG keep 16 lines interleaved in a sense and might need to touch quite a bit of data. http://trac.osgeo.org/gdal/ticket/3894 2011-01-03 Lee Howard * libtiff/tif_jpeg.c: Fix regressions with 2 and 3 band images caused by commit on 2010-12-14. Submitted by e-mail from Even Rouault 2010-12-31 Olivier Paquet * libtiff/tif_dirwrite.c: Fixed writing of TIFFTAG_REFERENCEBLACKWHITE. http://bugzilla.maptools.org/show_bug.cgi?id=2266 2010-12-23 Andrey Kiselev * tools/tiffcp.c, man/tiffcp.1: Added support for specifying the compression level parameter (preset) for Deflate and LZMA encoders, e.g "-c lzma:p1" or "-c zip:p9". * libtiff/tif_lzma.c: Properly set the LZMA2 compression level (preset) in LZMAVSetField(). 2010-12-18 Bob Friesenhahn * libtiff/Makefile.am (libtiff_la_SOURCES): Added tif_lzma.c to Makefile. 2010-12-14 Andrey Kiselev * configure.ac, libtiff/{tif_codec.c, tif_config.h.in, tiff.h, tiffiop.h, tif_lzma.c}, tools/tiffcp.c, man/tiffcp.1: Implement a new TIFF compression scheme LZMA reserving a new value 34925 for Compression tag.

Patch by Vincent Torri. 2010-10-21 Frank Warmerdam * tools/tiffinfo.c: avoid direct reference to _TIFFerrorHandler. * libtiff/tif_config.vc.h: define snprintf to _snprintf for tiff2pdf. * libtiff/libtiff.def: export _TIFFCheckMalloc for tools. 2010-09-25 Lee Howard * tools/tiff2ps.c: improvements and enhancements from Richard Nolde with additional command line options for Document Title, Document Creator, and Page Orientation 2010-07-13 Bob Friesenhahn * tools/tiffcrop.c: Patch from Richard Nolde to avoid a potentially unterminated buffer due to using an exceptionally long file name. 2010-07-08 Andrey Kiselev * tools/tiff2pdf.c: Fixed ID buffer filling in t2p_write_pdf_trailer(), thanks to Dmitry V. Levin. 2010-07-07 Andrey Kiselev * libtiff/tif_dirread.c: Really reset the tag count in CheckDirCount() to expected value as the warning message suggests. As per bug http://bugzilla.maptools.org/show_bug.cgi?id=1963 2010-07-06 Andrey Kiselev * tools/tiffset.c: Properly handle TIFFTAG_PAGENUMBER, TIFFTAG_HALFTONEHINTS, TIFFTAG_YCBCRSUBSAMPLING, TIFFTAG_DOTRANGE which should be set by value. * libtiff/tif_dirinfo.c: Don't use assertions in _TIFFFieldWithTag() and _TIFFFieldWithName() if the tag is not found in the tag table. This should be normal situation and returned NULL value should be properly handled by the caller. 2010-07-02 Andrey Kiselev * libtiff/tif_getimage.c: Avoid wrong math du to the signed/unsigned integer type conversions. As per bug http://bugzilla.maptools.org/show_bug.cgi?id=2207 * tools/{tiff2bw.c, thumbnail.c, pal2rgb.c}: Fix the count for WhitePoint tag as per bug http://bugzilla.maptools.org/show_bug.cgi?id=2042 * libtiff/tif_getimage.c: Check the number of samples per pixel when working with YCbCr image in PickContigCase(). As per bug http://bugzilla.maptools.org/show_bug.cgi?id=2216 * libtiff/tif_dir.c: Set the bogus post-decoding hook when processing TIFFTAG_BITSPERSAMPLE in _TIFFVSetField() for the case of 8 bit when we don't need any post-processing. That helps to reset the hook if we previously set this field to some other value and the hook was initialized accordingly. As per bug http://bugzilla.maptools.org/show_bug.cgi?id=2035 2010-07-01 Andrey Kiselev * tools/tiffgt.c: Properly check the raster buffer allocations for integer overflows. As per bug http://bugzilla.maptools.org/show_bug.cgi?id=2108 * m4/acinclude.m4: Update GL/GLU/GLUt/Pthread macros from the upstream. * libtiff/{tif_aux.c, tif_strip.c, tif_tile.c, tiffiop.h}: Move multiply_32() and multiply_64() functions into tif_aux.c file and rename them into _TIFFMultiply32() and _TIFFMultiply64() respectively. 2010-06-30 Andrey Kiselev * tools/tiff2pdf.c: Better generation of ID field in t2p_write_pdf_trailer(). Get rid of GCC aliasing warnings. * tools/tiff2pdf.c: Fixed computation of the tile buffer size when converting JPEG encoded tiles. * tools/tiff2pdf.c: Better handling of string fields, use static string buffers instead of dynamically allocated, use strncpy() instead of strcpy(), control the string lengths. 2010-06-25 Andrey Kiselev * tools/tiffcp.c: Initialize buffer arrays with zero to avoid referencing to uninitialized memory in some cases (e.g. when tile size set bigger than the image size). 2010-06-15 Bob Friesenhahn * tools/tiffcrop.c: Patch from Richard Nolde. Reject YCbCr subsampled data since tiffcrop currently doesn't support it. Fix JPEG support. 2010-06-13 Frank Warmerdam * libtiff/tif_dirinfo.c: Fix invocation of tag compare function (#2201) * tools/tiff2pdf.c: Fix assorted bugs in tiff2pdf: missing "return" in t2p_read_tiff_size() causes t2p->tiff_datasize to be set entirely wrong for COMPRESSION_JPEG case, resulting in memory stomp if actual size is larger. Also, there are a bunch of places that try to memset() a malloc'd buffer before checking for malloc failure, which would result in core dump if there actually were a failure. (#2211) 2010-06-11 Bob Friesenhahn * libtiff/tiffiop.h (TIFFSafeMultiply): Need more castings to avoid compiler warnings if parameter types are not sign consistent. * libtiff 4.0.0alpha6 released. * tools/tiffcrop.c: Applied patch from Richard Nolde: Corrected European page size dimensions. Added an option to allow the user to specify a custom page size on the command line. Fix the case where a page size specified with a fractional part was being coerced to an integer by retyping the variables that define the paper size. * html/index.html: Update for the 3.9.3 release. * tools/tiffcp.c (tiffcp): Applied Tom Lane's patch to reject YCbCr subsampled data since tiffcp currently doesn't support it. http://bugzilla.maptools.org/show_bug.cgi?id=2097 * Update libtool to version 2.2.10. 2010-06-10 Bob Friesenhahn * libtiff/tiffiop.h (TIFFSafeMultiply): Work properly if multiplier is zero. 2010-06-09 Bob Friesenhahn * libtiff/tif_fax3.c (Fax3SetupState): Yesterday's fix for CVE-2010-1411 was not complete. * libtiff/tiffiop.h (TIFFSafeMultiply): New macro to safely multiply two integers. Returns zero if there is an integer overflow. * tools/tiffcp.c (main): tiffcp should not leak memory if an error is reported when reading the input file. 2010-06-08 Bob Friesenhahn * Update libtool to version 2.2.8. * libtiff/tif_fax3.c (Fax3SetupState): Avoid under-allocation of buffer due to integer overflow in TIFFroundup() and several other potential overflows. In conjunction with the fix to TIFFhowmany(), fixes CVE-2010-1411. * libtiff/tiffiop.h (TIFFhowmany): Return zero if parameters would result in an integer overflow. This causes TIFFroundup() to also return zero if there would be an integer overflow. * contrib: Add an emacs formatting mode footer to all source files so that emacs can be effectively used. 2010-06-03 Oliver Chen Feng * libtiff/tools/tiffcp.c: add a new option -x to force merged tiff file PAGENUMBER value in sequence for users who care the page sequence, this will also prevent tiff2pdf from creating pdf file from the merged tiff file with wrong page sequence. 2010-05-08 Olivier Paquet * libtiff/tif_dirread.c: Restored TIFFReadDirEntryFloat function in order to add missing TIFF_SETGET_FLOAT case to TIFFFetchNormalTag. * libtiff/tif_dirinfo.c: Use correct set_field_type for TIFFTAG_PIXAR_FOVCOT so it is readable again (regression from 3.9.2). http://bugzilla.maptools.org/show_bug.cgi?id=2192 2010-05-07 Frank Warmerdam * libtiff/tif_jpeg.c: Ensure that quality is always set in JPEGPreEncode(), not just when we want to output local tables. Otherwise the quality used during compression may not be right and might not match the tables in the tables tag. This bug only occurs when seeking between directories in the midst of writing blocks. http://trac.osgeo.org/gdal/ticket/3539 2010-05-06 Andrey Kiselev * html/man/TIFFGetField.3tiff.html, html/man/TIFFSetField.3tiff.html: Regenerated from the source. 2010-05-05 Olivier Paquet * libtiff/tif_print.c: Fixed printing of TIFFTAG_REFERENCEBLACKWHITE which had stopped working. Also made it always print 6 floats instead of 2*SamplesPerPixel. http://bugzilla.maptools.org/show_bug.cgi?id=2191 http://bugzilla.maptools.org/show_bug.cgi?id=2186 * man/TIFFGetField.3tiff, man/TIFFSetField.3tiff: Fixed doc to reflect the fact that libtiff considers TIFFTAG_REFERENCEBLACKWHITE to be 6 floats. 2010-05-05 Frank Warmerdam * libtiff/tif_jpeg.c: Fix to use memcmp(), not memcpy() when checking if the jpeg table was written. This is a fix for the last fix on 04-21. 2010-04-21 Frank Warmerdam * libtiff/tif_jpeg.c: avoid preparing jpeg tables everytime JPEGSetupEncode() is called if the tables already seem to be established. This prevents spurious updates and rewriting of directories with jpegtables when doing updates to existing images. http://trac.osgeo.org/gdal/ticket/3539 2010-04-20 Olivier Paquet * libtiff/tif_dirinfo.c: Use correct set_field_type for TIFFTAG_PIXAR_IMAGEFULLWIDTH, TIFFTAG_PIXAR_IMAGEFULLLENGTH, TIFFTAG_PIXAR_MATRIX_WORLDTOSCREEN and TIFFTAG_PIXAR_MATRIX_WORLDTOCAMERA. They were unreadable with TIFF_SETGET_UNDEFINED, a regression from 3.9.2. http://bugzilla.maptools.org/show_bug.cgi?id=2139 2010-04-10 Bob Friesenhahn * libtiff/tif_dir.c (_TIFFVSetField): Add a special error case for when the tag count value is zero. Error handling is still a regression since in 3.9.2, empty tags are skipped (with a warning) rather than returning a hard error and refusing to read the file. * tools/ppm2tiff.c (main): While case for parsing comment line requires extra parenthesis to work as expected. Reported by Thomas Sinclair. 2010-04-02 Frank Warmerdam * libtiff/tif_read.c (primarily): Add support for CHUNKY_STRIP_READ_SUPPORT where large strips are read in chunks for applications using TIFFReadScanline(). This is intended to make it more practical work with very large compressed one-strip files. Feature is off by default. Enable by defining CHUNK_STRIP_READ_SUPPORT as a macro. http://trac.osgeo.org/gdal/ticket/3514 2010-03-31 Frank Warmerdam * libtiff/tif_flush.c: Use TIFFRewriteDirectory() when flushing directories so previously placed directories will be migrated to the end of file if needed. 2010-03-30 Frank Warmerdam * libtiff/tif_lzw.c: change type of dec_bitsleft field to uint64 to support operating on strips/tiles of more than 256MB. http://trac.osgeo.org/gdal/ticket/3512 2010-03-10 Bob Friesenhahn * libtiff/tif_aux.c (_TIFFCheckRealloc): Improve error message so that it is clearly a memory allocation error message, and also includes the size of the allocation request. 2010-02-22 Lee Howard * libtiff/tif_jpeg.c: Do not generate a JPEGTables tag when creating the JPEG TIFF as is is not required in order to prevent it from being unused and filled with invalid data. (Leave it to be generated by later activity.) http://bugzilla.maptools.org/show_bug.cgi?id=2135 * tools/tiff2pdf.c: Write the JPEG SOI headers into the TIFF strip data rather than skipping them. This fixes the ability to view in Acrobat Reader, Evince, and Ghostscript. http://bugzilla.maptools.org/show_bug.cgi?id=2135 * libtiff/tif_fax3.c: Don't return error on badly-terminated MMR strips. http://bugzilla.maptools.org/show_bug.cgi?id=2029 2009-12-03 Frank Warmerdam * libtiff/tif_jpeg.c: Made JPEGDecodeRaw() check for buffer overruns. Made so that when working with downsampled images a stub function reporting an error is used for tif_decoderow. We cannot meaningfully support reading scanlines in this situation. (#1936) * libtiff/tif_jpeg.c: Ensure that tif_scanlinesize is computed after resetting of the upsampling values (gdal:#3259). http://bugzilla.maptools.org/show_bug.cgi?id=1936 2009-11-30 Frank Warmerdam * contrib/dbs/tiff-grayscale.c, contrib/tif-palette.c, tools/ras2tiff.c: Fix resource leaks on error. http://bugzilla.maptools.org/show_bug.cgi?id=2121 * libtiff/tif_{aux.c,dir.c,dir.h,dirinfo.c}: Return to handling TIFFTAG_REFERENCEBLACKWHITE as a field in the TIFF directory instead of as a custom(generic) field to avoid a potential reentrancy problem. http://bugzilla.maptools.org/show_bug.cgi?id=2125 * libtiff/tif_color.c, libtiff/tif_getimage.c, libtiff/tiffio.h, man/TIFFcolor.3tiff: Make TIFFDisplay argument in TIFFCIELabToRGBInit const, and display_sRGB static and const. http://bugzilla.maptools.org/show_bug.cgi?id=2124 2009-11-04 Bob Friesenhahn * libtiff 4.0.0alpha5 released. 2009-11-03 Bob Friesenhahn * tools/tiffcrop.c: Updated tiffcrop from Richard Nolde. This version has undergone substantial testing with arbitrary sample bit depths. Also eliminates GCC compilation warnings. 2009-11-02 Bob Friesenhahn * port/libport.h: Add extern declarations for getopt standard globals. 2009-10-31 Bob Friesenhahn * libtiff/tif_lzw.c (LZWDecode, LZWDecodeCompat): Fix warnings noticed in 64-bit build of libtiff with Visual Studio 2005. Resolves "Bug 2067 - Visual Studio 2005 64-bit warnings in tif_lzw.c", http://bugzilla.maptools.org/show_bug.cgi?id=2067 * libtiff/tif_pixarlog.c (PixarLogEncode): Fix non-important warning noticed in Visual Studio 2005 build.

Register a private error callback to accomplish that. * test/Makefile.am (TIFFIMAGES): Add test images in BMP, GIF, and PNM formats so that we will be able to test more of the tools. While adding these test images I notice that bmp2tiff and gif2tiff only support ancient versions of their respective formats. 2009-08-27 Bob Friesenhahn * libtiff 4.0.0alpha4 released. * HOWTO-RELEASE: Improved release instructions. 2009-08-24 Bob Friesenhahn * man/{TIFFClose.3tiff,raw2tiff.1,tiffcmp.1,tiffsplit.1}: Applied fixes for "Bug 2023 - nroff errors in manual pages". http://bugzilla.maptools.org/show_bug.cgi?id=2023 * tools/{rgb2ycbcr.c, tiff2rgba.c}: Applied fixes for "Bug 2079 - CVE-2009-2347 libtiff: integer overflows in various inter-color space conversion tools". http://bugzilla.maptools.org/show_bug.cgi?id=2079 * libtiff/tif_print.c (TIFFPrintDirectory): Apply fix from Jay Berkenbilt for "Bug 2024 - possible null pointer dereference with one-line fix". http://bugzilla.maptools.org/show_bug.cgi?id=2024 * libtiff/tif_dirread.c (TIFFReadCustomDirectory): Apply patch from Jay Berkenbilt for "Bug 1895 - logic error in tif_dirread.c: segfault after setting tdir_tag = IGNORE". http://bugzilla.maptools.org/show_bug.cgi?id=1895 2009-08-23 Bob Friesenhahn * test/Makefile.am, test/tiffcrop*.sh: Split previously existing tiffcrop.sh into a collection of many specific tests. Re-wrote all of the existing tests to be based on some simple shell functions. Make distcheck works again. Export certain variables (MAKE, MAKEFLAGS, MEMCHECK) to tests and added 'memcheck' and 'ptrcheck' targets to make it easy to run the tests under valgrind. 2009-08-21 Bob Friesenhahn * test/tiffcp-logluv.sh: Fix test so that it works with a VPATH build. * test/Makefile.am (AUTOMAKE_OPTIONS): Colorized tests was not actually activated since it needed to be enabled in this Makefile.am.

In particular, support for rotating the image by 90, 180, 270, and 'auto' has been added. * man/tiffcrop.1: Incorporated documentation updates from Richard Nolde. * tools/tiffcrop.c: Incorporated significant functionality update from Richard Nolde. 2008-12-31 Bob Friesenhahn * libtiff/tiffio.h: GCC will now validate format specifications for TIFFError(), TIFFErrorExt(), TIFFWarning(), and TIFFWarningExt() in order to reveal bugs. * Many fixes throughout to work better as a 64-bit build. 2008-12-30 Bob Friesenhahn * tools/{tiff2pdf.c, tiff2ps.c, tiffinfo.c}: Offset and length tags now require 64-bit parameter rather than 32-bit. * libtiff/tif_dirread.c: Fixed issues with unaligned access to 64-bit values. * tools/thumbnail.c: Eliminate crash noticed while running test suite. 2008-12-29 Bob Friesenhahn * libtiff/tif_ojpeg.c (OJPEGLibjpegJpegSourceMgrFillInputBuffer): Initialize stack variables to avoid compiler warning. * tools/tiffinfoce.c (main): Use toff_t for offset type when retrieving offset of EXIF IFD. * libtiff/tiffio.h: Undeprecate toff_t and restore its use in the TIFFClientOpen() callback and other external function definitions. * tools/tiffinfo.c (main): Offset to EXIF IFD requires a 64-bit type now. Fixes crash when dumping files containing an EXIF IFD. * m4/libtool.m4: Update to libtool 2.2.6. 2008-12-21 Frank Warmerdam * libtiff/tif_dir.c, tiffio.h: Introduce TIFFUnsetField() function. * libtiff/tif_jpeg.c: Avoid errors if the application writes a full strip for the last partial strip in a jpeg compressed file. http://bugzilla.maptools.org/show_bug.cgi?id=1981 2008-10-29 Frank Warmerdam * libtiff/tif_flush.c: Make sure that BEENWRITING is cleared when we take the shortcut to only update the strip/tile offsets in place. http://trac.osgeo.org/gdal/ticket/2621 2008-10-21 Andrey Kiselev * libtiff/tif_jbig.c: Support the JBIG-KIT 2.0 (compatibility with the older versions retained). 2008-10-09 Frank Warmerdam * libtiff/tif_jpeg.c: Add #ifdefs for changes needed if using IPP enabled version of libjpeg from Intel. http://bugzilla.maptools.org/show_bug.cgi?id=1951 2008-09-05 Andrey Kiselev * tools/tiffsplit.c: Use byte counts of proper size (uint64). Required for libtiff 4.0. * tools/tiffsplit.c: Use dynamically allocated array instead of static when constructing output file names. 2008-09-03 Andrey Kiselev * tools/tiffsplit.c: Get rid of unsafe strcpy()/strcat() calls when doing the filename/path construction. * tools/tiff2pdf.c: More appropriate format string in t2p_write_pdf_string(); avoid signed/unsigned mismatch. * libtiff/tif_lzw.c: Properly zero out the codetable. As per bug http://bugzilla.maptools.org/show_bug.cgi?id=1929 * libtiff/tif_lzw.c: Properly zero out the string table. Fixes CVE-2008-2327 security issue. 2008-09-01 Frank Warmerdam * libtiff/tif_dirread.c: Avoid unused TIFFReadDirEntryFloat() function. * libtiff/tif_dirwrite.c: modified to write IFDs as either IFD8 or IFD depending on whether the file is bigtiff or classic tiff. http://bugzilla.maptools.org/show_bug.cgi?id=1917 2008-08-12 Edward Lam * tools/tiffdump.c: When compiling for Microsoft Windows, apply consistent (__int64) casting when testing if _lseeki64 has successfully seeked as requested. This is necessary for large file support to work since off_t is only 32-bit. 2008-07-29 Frank Warmerdam * tif_strip.c: Replace assertions related to samplesperpixel != 3 or the subsampling values not being 1, 2 or 4 (for jpeg compressed images) with control logic to return runtime errors (c/o Even Rouault) (#1927). 2008-06-17 Frank Warmerdam * tools/tiffcrop.c: Fix some portability problems. * libtiff/tif_ojpeg.c: Use same jpeg/win32 boolean/FAR hacks as are used in tif_jpeg.c. * libtiff/tif_win32.c: Ensure TIFFOpenW() uses same FILE_SHARE flags as TIFFOpen(). 2008-06-01 Frank Warmerdam * libtiff/tif_dirwrite.c: Fix alignment problems affecting architectures like Sparc/Solaris. http://bugzilla.maptools.org/show_bug.cgi?id=1892 2008-05-27 Frank Warmerdam * libtiff.def: Add TIFFFindField http://bugzilla.maptools.org/show_bug.cgi?id=1891 2008-05-26 Frank Warmerdam * tif_config.*.h, tiffconf.*.h: Remove SIZEOF_LONG definition, unused. * li2008-04-15 Andrey Kiselev btiff/tif_win32.c: Replace custom Win32 memory api with generic POSIX one. No apparent value to use of GlobalAlloc() in the modern age. http://bugzilla.maptools.org/show_bug.cgi?id=1885 * libtiff/tiffconf.vc.h: Added JBIG_SUPPORT and MDI_SUPPORT items in windows version (care of Edward Lam). 2008-05-24 Frank Warmerdam * tif_codec.c: Avoid NULL pointer dereferencing for exotic compression codec codes. * tif_dirwrite.c: fix potential memory leak. * tif_dirread.c: Fix unchecked malloc result. 2008-05-24 Bob Friesenhahn * test {tiff2pdf.sh tiff2ps-EPS1.sh tiff2ps-PS1.sh tiff2ps-PS2.sh tiff2ps-PS3.sh tiffcp-g3-1d-fill.sh tiffcp-g3-1d.sh tiffcp-g3-2d-fill.sh tiffcp-g3-2d.sh tiffcp-g3.sh tiffcp-g4.sh tiffcp-split-join.sh tiffcp-split.sh tiffcp-thumbnail.sh tiffdump.sh tiffinfo.sh}: Added more test scripts based on suggestions from Lee Howard posted to the tiff list on 13 Sep 2007. 2008-05-23 Frank Warmerdam * libtiff/tif_fax3.c: Add an assert in an effort to detect a possible runtime problem reported by coverity. * contrib/iptcutil/iptcutil.c: Fixed memory leak of str. * tools/tiffcrop.c, man/tiffcrop.1: Major update from Richard Nolde. http://bugzilla.maptools.org/show_bug.cgi?id=1888 * tools/tiffdither.c: remove dead onestrip code. avoid memory leak. * tools/rgb2ycbcr.c: fix memory leak of raster buffer. * tools/tiffcp.c: Simplify inknames code to avoid pointless test. Cleanup scanline allocation to avoid coverity warning. * tools/thumbnail.c: Check for TIFFOpen() failure. 2008-05-18 Frank Warmerdam * libtiff/tif_dirinfo.c: Use TIFF_SETGET_ASCII for PIXAR_TEXTUREFORMAT and PIXAR_WRAPMODES instead of TIFF_SETGET_UNDEFINED. Not exactly clear why this is needed. 2008-05-09 Bob Friesenhahn * Makefile.am (ACLOCAL_AMFLAGS): Libtool 2.2.4 does not like "ACLOCAL_AMFLAGS=-I ./m4". It wants "ACLOCAL_AMFLAGS=-I m4". 2008-04-15 Andrey Kiselev * test/: Test suite updated. Everything is passed now. * libtiff/tif_dirinfo.c: Fixed description of the TIFFTAG_NUMBEROFINKS tag. 2008-04-14 Andrey Kiselev * libtiff/{tif_dirread.c, tif_dirwrite.c, tiffiop.h}: Get rid of some of "dereferencing type-punned" warnings by converting tdir_offset field of TIFFDirEntry structure into union. 2008-04-10 Andrey Kiselev * libtiff/{tif_flush.c, tif_dirwrite.c, tiffio.h, tiffiop.h}: TIFFRewriteField() renamed into _TIFFRewriteField() and moved out from the public interface. Type of its 'count' parameter changed from uint32 to tmsize_t. * /libtiff/tiffiop.h: Make tif_nfields and tif_nfieldscompat fields of the tiff structure have the size_t type instead of uint32. 2008-04-09 Andrey Kiselev * tools/tiffdump.c: Added support for MSVS 6.0. * libtiff/tif_dirread.c: Use custom functions _TIFFUInt64ToFloat() and _TIFFUInt64ToDouble() to convert 64-bit integers into floating point values on MSVS 6.0 platform. 2008-03-14 Frank Warmerdam * tif_dirread.c: Removed sanity checks on tags larger than 4MB in TIFFReadDirEntryArray() since they are interfering with seemingly legitimate files. http://trac.osgeo.org/gdal/ticket/2005 2008-02-09 Joris Van Damme * tif_dirread.c: Added handling for the case of number of values for PageNumber tag different from 2 (previously resulted in an assert indicating lack of handling and was forgotten about) 2008-02-01 Frank Warmerdam * libtiff/tif_jpeg.c: Do not try to fixup subsampling tags based on the actual jpeg data stream if the first strip/tile has zero size. This is the case when GDAL creates a new file with zero sizes, closes and reopens it. 2008-01-07 Frank Warmerdam * tools/tiff2ps.c: fix up 64bit issues (from Edward Lam). 2008-01-01 Frank Warmerdam * libtiff/tif_dirwrite.c: #ifdef out lots of unused functions. * Makefile.vc, libtiff/Makefile.vc, tools/Makefile.vc: Improve clean targets. * tools/tiffinfo.c, tools/tiffcmp.c, tools/gif2tiff.c, tools/bmp2tiff.c tools/tiff2pdf.c: Fix 64-bit warnings when compiling under MSVC 2005 (x64). * tools/tiffset.c: Changes to reflect the fact that TIFFFieldWithTag() and TIFFFieldWithName() now return TIFFField pointers instead of TIFFFieldInfo pointers. * tools/tiffdump.c: Added ssize_t typedef on Windows since it doesn't exist. This makes it compile again on Windows * tif_aux.c, tif_getimage.c, tif_next.c, tif_predict.c, tif_win32.c, tiffconf.vc.h: Various 64bit fixes from Edward Lam identified on win64. * test/rewrite_tag.c: New test for TIFFRewriteField(). 2007-12-31 Frank Warmerdam * tif_dirwrite.c: Added TIFFRewriteField(). This new function rewrites one field "on disk" updating an existing directory entry. Lots of limitations still... * tiffiop.h, tif_write.c, tif_dirread.c, tif_flush.c: Keep track of TIFF_DIRTYSTRIP separately from TIFF_DIRTYDIRECT to indicate that the strip offset/size values are dirty but nothing else about the directory is dirty. In flush handle "just stripmaps dirty" as a special case that just rewrites these values without otherwise modifying the directory on disk using TIFFRewriteField(). We also modify logic so that in update mode the directory is not marked dirty on read, but only when something is changed. This means we need to keep track of updates to the stripmap stuff in TIFFAppendToStrip(). 2007-12-10 Frank Warmerdam * tif_jpeg.c: Improve ability to switch between encoding and decoding in the jpeg code (gdal bug #2033). 2007-11-23 Frank Warmerdam * tif_dir.c, tif_dirread.c, tif_dirwrite.c, tif_read.c, tif_write.c, tiffiop.h: Added TIFF_BUF4WRITE flag to indicate if contents of the rawcp/rawcc buffer are for writing and thus may require flushing. Necessary to distinguish whether they need to be written to disk when in mixed read/write mode and doing a mixture of writing followed by reading. http://trac.osgeo.org/gdal/ticket/1758 2007-11-23 Andrey Kiselev * configure.com, libtiff/tif_vms.c: Better OpenVMS support. Patches from Alexey Chupahin. 2007-11-02 Frank Warmerdam * tif_write.c: Rip out the fancy logic in TIFFAppendToStrip() for establishing if an existing tile can be rewritten to the same location by comparing the current size to all the other blocks in the same directory. This is dangerous in many situations and can easily corrupt a file. (observed in esoteric GDAL situation that's hard to document). This change involves leaving the stripbytecount[] values unaltered till TIFFAppendToStrip(). Now we only write a block back to the same location it used to be at if the new data is the same size or smaller - otherwise we move it to the end of file. * tif_dirwrite.c: Try to avoid writing out a full readbuffer of tile data when writing the directory just because we have BEENWRITING at some point in the past. This was causing odd junk to be written out in a tile of data when a single tile had an interleaving of reading and writing with reading last. (highlighted by gdal autotest/gcore/tif_write.py test 7. * tif_predict.c: use working buffer in PredictorEncodeTile to avoid modifying callers buffer. http://trac.osgeo.org/gdal/ticket/1965 * tif_predict.c/h: more fixes related to last item, keeping a distinct pfunc for encode and decode cases as these were getting mixed up sometimes. http://trac.osgeo.org/gdal/ticket/1948 2007-11-01 Frank Warmerdam * tif_predict.c/h, tif_lzw.c, tif_zip.c: Improvements so that predictor based encoding and decoding works in read-write update mode properly. http://trac.osgeo.org/gdal/ticket/1948 2007-10-24 Joris Van Damme * tif_dirread.c: Fixed problem with bogus file triggering assert(td->td_planarconfig == PLANARCONFIG_CONTIG) in ChopUpSingleUncompressedStrip 2007-10-22 Joris Van Damme * tif_jpeg.c: Resolved buffer incrementation bug that lead to faulty images at best, access violation at worst, when subsampled JPEG compressed imagery is decoded without the JPEG_COLORMODE feature 2007-10-11 Frank Warmerdam * html/index.html: Update "people responsible" section. 2007-10-05 Frank Warmerdam * tools/tiff2pdf.c: Fix problem with alpha setting in some cases as reported on the mailing list. 2007-10-01 Joris Van Damme * changed some more incorrect %lud printf flags to %lu 2007-09-29 Joris Van Damme * tif_dirread.c: Strip chopping interfered badly with uncompressed subsampled images because it tried to divide subsampled rowblocks, leading to all sorts of errors throughout the library for these images. Fixed by making strip chopping divide in row counts that are a multiple of vertical subsampling value. 2007-09-28 Joris Van Damme * tif_dirread.c: Logical cast working around compiler warning * tif_read.c: Correction of some error flags and parameter lists 2007-09-27 Joris Van Damme * tif_dirread.c: Made calculation of td_maxsamplevalue more robust when dealing with large bitspersample values, shutting up purification tools that warn about truncation, though it remains incorrect and indicates a conceptual problem there. * tif_open.c: Moved early exit in case of 'h' flag (to disable reading of first IFD) to proper place because it badly interfered with memory mapping, resulting in mapping flag even with dummy mapping functions that returned 0 whilst at the same time the mapping tif_size wasn't set, thus resulting in continuous incorrect beyond-eof errors. 2007-09-24 Joris Van Damme * tif_dirinfo.c: Fixed (MSVC) compiler reports about inconsistent use of const in tiffFields and exifFields definition 2007-09-20 Frank Warmerdam * tif_dirwrite.c: Always write tile/strip offsets and sizes using LONG8 type when output format is BigTIFF. The TIFFWriteDirectoryTagLongLong8Array() function was restructured accordingly. * tif_dirread.c: Improvements to error reporting text in TIFFFetchDirectory(). 2007-09-19 Bob Friesenhahn * test/images: Added a small collection of test images for use by test programs and scripts. * test/tiffinfo.sh: A trivial example test script. * test/common.sh: Added small script for setting the environment used by script-based tests. 2007-08-24 Frank Warmerdam * tif_dirwrite.c: Write the tif_nextdiroff value instead of a fixed zero when writing directory contents to preserve the ability to rewrite directories in place, even in the middle of a directory chain. * tif_dirinfo.c: _TIFFMergeFields() now only merges in field definitions that are missing. Existing definitions are silently ignored. * tif_dirread.c: Add runtime error for fields for which no definition is found (in addition to an assert for developers) in TIFFFetchNormalTag(). Not sure if this is needed, but it seems prudent. 2007-08-10 Joris Van Damme * libtiff/tif_getimage.c: removed SubsamplingHor and SubsamplingVer from _TIFFRGBAImage structure to revert unwanted ABI change. 2007-08-10 Joris Van Damme * libtiff/tif_win32.c: use SetFilePointer instead of SetFilePointerEx, as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1580 2007-07-19 Andrey Kiselev * libtiff/tif_stream.cxx: Put all callback functions declarations inside extern "C" block. * libtiff/{tif_lzw.c, tif_luv.c, tif_dumpmode.c, tif_print.c, tif_read.c, tif_strip.c, tif_thunder.c}: Use "%I64d" printf() formatter instead of "%lld" with MSVC compiler. * libtiff/{tiffiop.h, tif_aux.c}: Added _TIFFUInt64ToFloat() and _TIFFUInt64ToDouble() functions. 2007-07-18 Andrey Kiselev * libtiff/tif_dirread.c: Handle the case of MSVC 6 when using 64-bit integer constants. * libtiff/{Makefile.am, Makefile.v}: Do not distribute tiffconf.h, remove tif_config.h/tiffconf.h during cleaning. As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1573 * libtiff/tif_unix.c: Do not use O_LARGEFILE. As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1577 2007-07-13 Andrey Kiselev * libtiff 4.0.0alpha released. 2007-07-12 Andrey Kiselev * tools/tiff2pdf.c: Added missed extern optind as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1567 * libtiff/{tif_close.c, tif_dirinfo.c, tiffiop.c, tif_dirread.c, tif_dir.h, tif_dir.c, tiffio.h}: Transition to the new-style tag extending scheme completed. 2007-07-11 Bob Friesenhahn * libtiff/tif_stream.cxx: Adapt to use toff_t again. Update to use standard C++ library size types and attempt to detect overflow cases. 2007-07-08 Andrey Kiselev * libtiff/{tif_jpeg.c, tif_dir.h, tif_dir.c, tif_dirinfo.c, tiffio.h, tif_ojpeg.c, tif_print.c, tif_fax3.c, tif_dirread.c}: More work on new tag extending scheme.

TIFFFieldInfo retained for the backward compatibility. 2007-07-05 Bob Friesenhahn * tools/tiff2pdf.c: Fix a compile problem when JPEG_SUPPORT is not defined. 2007-07-04 Andrey Kiselev * libtiff/{tif_dir.c, tiff.h, tiffio.h, libtiff.def}: Unused TIFFReassignTagToIgnore() function and TIFFIgnoreSense enumeration removed. * libtiff/{tif_dirinfo.c, tif_fax3.c, tif_jbig.c, tif_jpeg.c}: Move tags TIFFTAG_FAXRECVPARAMS, TIFFTAG_FAXSUBADDRESS, TIFFTAG_FAXRECVTIME and TIFFTAG_FAXDCS to the common tag directory. These tags are not codec-specific and relate to image content, so process them as other normal tags. * libtiff/{tiffio.h, tif_dir.h}: TIFFTagValue structure moved from the public tiffio.h to private tif_dir.h. * contrib/{acorn, mac-cw, mac-mpw}: Removed as unmaintained and outdated. 2007-07-03 Andrey Kiselev * libtiff{tif_acorn.c, tif_apple.c, tif_atari.c, tif_msdos.c, tif_win3.c}: Obsoleted portability stuff removed. * tools/tiff2ps.c: Added support 16-bit images as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1566 Patch from William Bader. * tools/tiff2pdf.c: Fix for TIFFTAG_JPEGTABLES tag fetching and significant upgrade of the whole utility as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1560 Now we don't need tiffiop.h in tiff2pdf anymore and will open output PDF file using TIFFClientOpen() machinery as it is implemented by Leon Bottou. 2007-06-26 Bob Friesenhahn * configure.ac: Fix typo when substituting value for unsigned 8 bit type.

Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=119 in case of _cvs_00000-00.tif, _cvs_00000-01.tif and _cvs_00000-02.tif. 2002-04-04 Andrey Kiselev * libtiff/: tif_lzw.c: Assertions in LZWDecode and LZWDecodeCompat replaced by warnings. Now libtiff should read corrupted LZW-compressed files by skipping bad strips. Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=100 2002-04-03 Frank Warmerdam * libtiff/tif_dirwrite.c: Removed some dead code. * libtiff/*: Cleanup some warnings. * libtiff/tif_dir.c: Fixed bug with count returned by TIFFGetField() for variable length FIELD_CUSTOM values. Was int * but should be u_short *. 2002-04-01 Andrey Kiselev * tools/: tifcp.c: Added support for 'Orientation' tag in tiffcp utility (at cpStripToTile routine). 2002-03-27 Frank Warmerdam * tif_dirread.c: avoid div-by-zero if rowbytes is zero in chop func. http://bugzilla.remotesensing.org/show_bug.cgi?id=111 * tif_print.c: Fixed so that ASCII FIELD_CUSTOM values with passcount set FALSE can be printed (such as TIFFTAG_SOFTWARE). * libtiff/tif_dir.c,tif_dirinfo.c,tif_dir.h,tif_ojpeg.c: modified so that TIFFTAG_SOFTWARE uses FIELD_CUSTOM as an example. 2002-03-26 Dwight Kelly * libtiff/: tiff.h, tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c, tif_dirwrite.c: Added get/put code for new tag XMLPACKET as defined in Adobe XMP Technote. Added missing INKSET tag value from TIFF 6.0 spec INKSET_MULTIINK (=2). Added missing tags from Adobe TIFF technotes: CLIPPATH, XCLIPPATHUNITS, YCLIPPATHUNITS, OPIIMAGEID, OPIPROXY and INDEXED. Added PHOTOMETRIC tag value from TIFF technote 4 ICCLAB (=9). 2002-03-26 Andrey Kiselev * libtiff/: tif_getimage.c: TIFFReadRGBAStrip and TIFFReadRGBATile now also uses TIFFRGBAImageOK before reading. This is additional fix for http://bugzilla.remotesensing.org/show_bug.cgi?id=110 2002-03-25 Andrey Kiselev * libtiff/: tif_getimage.c: Additional check for supported codecs added in TIFFRGBAImageOK and TIFFReadRGBAImage now uses TIFFRGBAImageOK before reading. Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=110 2002-03-15 Andrey Kiselev * libtiff/: tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c, tif_dirwrite.c: Added routine TIFFDataWidth for detrmining TIFFDataType sizes instead of working with tiffDataWidth array directly. Should prevent out-of-borders bugs in case of unknown or broken data types. EstimateStripByteCounts routine modified, so it won't work when tags with uknown sizes founded. Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=109 2002-03-13 Andrey Kiselev * libtiff/tif_getimage.c: Added support for correct handling `Orientation' tag in gtTileContig. Should be added in other gt* functions as well, but I have not images for testing yet. Partially resolves http://bugzilla.remotesensing.org/show_bug.cgi?id=23 2002-03-10 Andrey Kiselev * libtiff/: tif_dirinfo.c, tif_dirwrite.c: Added possibility to read broken TIFFs with LONG type used for TIFFTAG_COMPRESSION, TIFFTAG_BITSPERSAMPLE, TIFFTAG_PHOTOMETRIC. Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=99 2002-03-08 Andrey Kiselev * libtiff/Makefile.in, tools/Makefile.in: Shared library will not be stripped when installing, utility binaries will do. Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=93 2002-02-28 Frank Warmerdam * man/TIFFGetField: fixed type of TIFFTAG_COPYRIGHT. * man/libtiff.3t: added copyright tag info. 2002-02-11 Frank Warmerdam * libtiff/{tiff.h,tif_fax3.c}: Add support for __arch64__. http://bugzilla.remotesensing.org/show_bug.cgi?id=94 * man/Makefile.in: Patch DESTDIR handling http://bugzilla.remotesensing.org/show_bug.cgi?id=95 * configure: OpenBSD changes for Sparc64 and DSO version. http://bugzilla.remotesensing.org/show_bug.cgi?id=96 2002-02-05 Frank Warmerdam * config.site/configure: added support for OJPEG=yes option to enable OJPEG support from config.site. 2002-01-27 Frank Warmerdam * html/document.html: fixed links for TIFf 6 docs. 2002-01-18 Frank Warmerdam * config.guess, config.sub: Updated from ftp.gnu.org/pub/config. * libtiff/tif_read.c: Fixed TIFFReadEncodedStrip() to fail if the decodestrip function returns anything not greater than zero as per http://bugzilla.remotesensing.org/show_bug.cgi?id=97 * configure: Modify CheckForBigEndian so it can work in a cross compiled situation. 2002-01-16 Frank Warmerdam * tools/tiffdump.c: include TIFFTAG_JPEGTABLES in tag list. * tools/tiffset.c: fix bug in error reporting. * tools/tiffcp.c: fix several warnings that show up with -Wall. 2002-01-04 Frank Warmerdam * libtiff/tif_jpeg.c: fixed computation of segment_width for tiles files to avoid error about it not matching the cinfo.d.image_width values ("JPEGPreDecode: Improper JPEG strip/tile size.") for ITIFF files. Apparently the problem was incorporated since 3.5.5, presumably during the OJPEG/JPEG work recently. 2001-12-15 Frank Warmerdam * configure, libtiff/Makefile.in: Changes for building on MacOS 10.1. http://bugzilla.remotesensing.org/show_bug.cgi?id=94 * libtiff/tif_getimage.c: If DEFAULT_EXTRASAMPLE_AS_ALPHA is 1 (defined in tiffconf.h - 1 by default) then the RGBA interface will assume that a fourth extra sample is ASSOCALPHA if the EXTRASAMPLE value isn't set for it. This changes the behaviour of the library, but makes it work better with RGBA files produced by lots of applications that don't mark the alpha values properly. http://bugzilla.remotesensing.org/show_bug.cgi?id=93 http://bugzilla.remotesensing.org/show_bug.cgi?id=65 2001-12-12 Frank Warmerdam * libtiff/tif_jpeg.c: allow jpeg data stream sampling values to override those from tiff directory.

Updated TIFFWriteDirectory man page to include TIFFRewriteDirectory. 2001-09-24 Frank Warmerdam * libtiff/tif_lzw.c: Avoid MS VC++ 5.0 optimization bug. http://bugzilla.remotesensing.org/show_bug.cgi?id=78 * libtiff/tif_lzw.c: added dummy LZWSetupEncode() to report an error about LZW not being available. * libtiff/tif_dir.c: propagate failure to initialize compression back from TIFFSetField() as an error status, so applications can detect failure. * libtiff/tif_dir.c: removed the auto replacement of COMPRESSION_LZW with COMPRESSION_NONE in _TIFFVSetField(). * Removed Makefile, tools/Makefile, port/install.sh, man/Makefile from CVS as they are all supposed to be auto-generated by configure. 2001-09-22 Frank Warmerdam * libtiff/tif_ojpeg.c: new update from Scott. 2001-09-09 Frank Warmerdam * libtif/tif_fax3.c: Removed #ifdef PURIFY logic, and modified to always use the "safe" version, even if there is a very slight cost in performance. http://bugzilla.remotesensing.org/show_bug.cgi?id=54 * libtiff/Makefile.in: Fixed @DSOSUB_VERSION to be @DSOSUF_VERSION@ in two places. * libtiff/tif_getimage.c: Fixed problem with reading strips or tiles that don't start on a tile boundary. Fix contributed by Josep Vallverdu (from HP), and further described in bug 47. http://bugzilla.remotesensing.org/show_bug.cgi?id=47 * tools/tiff2ps.c: added OJPEG YCbCr to RGB support. * libtiff/tif_ojpeg.c: Applied substantial patch from Scott. 2001-09-06 Frank Warmerdam * libtiff/tif_packbits.c: fixed memory overrun error. http://bugzilla.remotesensing.org/show_bug.cgi?id=77 2001-08-31 Frank Warmerdam * libtiff/tif_getimage.c: relax handling of contig case where there are extra samples that are supposed to be ignored. This should now work for 8bit greyscale or palletted images. http://bugzilla.remotesensing.org/show_bug.cgi?id=75 2001-08-28 Frank Warmerdam * libtiff/tif_getimage.c: Don't complain for CMYK (separated) images with more than four samples per pixel. See: http://bugzilla.remotesensing.org/show_bug.cgi?id=73 2001-08-10 Frank Warmerdam * libtiff/tif_getimage.c: Use memmove() instead of TIFFmemcpy() in TIFFReadRGBATile() to avoid issues in cases of overlapping buffers. See Bug 69 in Bugzilla. http://bugzilla.remotesensing.org/show_bug.cgi?id=69 * tools/tiff2rgba.c: fixed getopt() call so that -b works again. 2001-08-09 Frank Warmerdam * libtiff/tiff.h, libtiff/tif_fax3.c: added check for __LP64__ when checking for 64 bit architectures as per bugzilla bug 67. 2001-07-27 Frank Warmerdam * man/Makefile.in: add TIFFClientOpen link as per debian submitted bug 66. 2001-07-20 Frank Warmerdam * libtiff/tif_jpeg.c: Define HAVE_BOOLEAN on windows if RPCNDR.H has been included. 2001-07-19 Frank Warmerdam * libtiff/tif_open.c: Seek back to zero after failed read, before writing header. 2001-07-18 Frank Warmerdam * libtiff/tif_ojpeg.c: updates from Scott. Handles colors much better. Now depends on having patched libjpeg as per patch in contrib/ojpeg/*. 2001-07-17 Frank Warmerdam * */Makefile.in: added DESTDIR support. http://bugzilla.remotesensing.org/show_bug.cgi?id=60 2001-07-16 Frank Warmerdam * configure, libtiff/Makefile.in: applied OpenBSD patches as per: http://bugzilla.remotesensing.org/show_bug.cgi?id=61 2001-06-28 Frank Warmerdam * libtiff/tif_getimage.c: Fixed so that failure is properly reported by gtTileContig, gtStripContig, gtTileSeparate and gtStripSeparate. See http://bugzilla.remotesensing.org/show_bug.cgi?id=51 * tiffcmp.c: Fixed multi samples per pixel support for ContigCompare. Updated bug section of tiffcmp.1 to note tiled file issues. See http://bugzilla.remotesensing.org/show_bug.cgi?id=53 2001-06-22 Frank Warmerdam * configure: Changes for DSO generation on AIX provided by John Marquart . * configure, libtiff/Makeifle.in: Modified to build DSOs properly on Darwin thanks to Robert Krajewski (rpk@alum.mit.edu) and Keisuke Fujii (fujiik@jlcuxf.kek.jp). 2001-06-13 Frank Warmerdam * tools/tiff2rgba.c: added -n flag to avoid emitting alpha component. * man/tiff2rgba.1: new 2001-05-22 Frank Warmerdam * Added tiffset and tif_ojpeg to the dist lists in Makefile.in. 2001-05-13 Frank Warmerdam * libtiff/tools/thumbnail.c: changed default output compression to packbits from LZW since LZW isn't generally available. 2001-05-12 Frank Warmerdam * libtiff/tif_ojpeg.c: New. libtiff/tif_jpeg.c, tiffconf.h, tif_getimage.c: changes related to OJPEG support. Scott Marovich supplied OJPEG support. 2001-05-11 Frank Warmerdam * tiff.h: removed, it duplicates libtiff/tiff.h. 2001-05-08 Frank Warmerdam * libtiff/tif_dirinfo.c: moved pixar and copyright flags to ensure everything is in order. * libtiff/libtiff.def: added TIFFCreateDirectory and TIFFDefaultStripSize as per: http://bugzilla.remotesensing.org/show_bug.cgi?id=46 2001-05-02 Frank Warmerdam * libtiff/tif_dirinfo.c: Modified the TIFF_BYTE definition for TIFFTAG_PHOTOSHOP to use a writecount of TIFF_VARIABLE2 (-3) to force use of uint32 counts instead of short counts. * libtiff/tif_dirwrite.c: Added support for TIFF_VARIABLE2 in the case of writing TIFF_BYTE/TIFF_SBYTE fields. http://bugzilla.remotesensing.org/show_bug.cgi?id=43 2001-05-01 Frank Warmerdam * libtiff/tif_dirinfo.c: removed duplicate TIFFTAG_PHOTOSHOP as per bug report http://bugzilla.remotesensing.org/show_bug.cgi?id=44 2001-04-05 Frank Warmerdam * tiffio.h: removed C++ style comment. * configure: fixed up SCRIPT_SH/SHELL handling. * Makefile.in: Fixed SCRIPT_SH/SHELL handling. * config.guess: documented more variables as per bug 40. 2001-04-03 Frank Warmerdam * configure, *Makefile.in: Various changes to improve configuration for HP/UX specifically, and also in general. They include: - Try to handle /usr/bin/sh instead of /bin/sh where necessary. - Upgrade to HP/UX 10.x+ compiler, linker and dso options. - Fixed mmap() test to avoid MMAP_FIXED ... it isn't available on HP - Use -${MAKEFLAGS} in sub makes from makefiles. http://bugzilla.remotesensing.org/show_bug.cgi?id=40 2001-04-02 Frank Warmerdam * libtiff/tiff.h: Applied hac to try and resolve the problem with the inttypes.h include file on AIX. See http://bugzilla.remotesensing.org/show_bug.cgi?id=39 * VERSION: update to 3.5.7 beta in preparation for release. * configure/config.site: modified to check if -lm is needed for MACHDEPLIBS if not supplied by config.site. Needed for Darwin. * config.guess: updated wholesale to an FSF version apparently from 1998 (as opposed to 1994). This is mainly inspired by providing for MacOS X support. 2001-03-29 Frank Warmerdam * configure, Makefile.in, etc: added support for OPTIMIZER being set from config.site. 2001-03-28 Frank Warmerdam * fax2ps.c: Helge (libtiff at oldach.net) submitted fix: Here's a fix for fax2ps that corrects behaviour for non-Letter paper sizes. It fixes two problems: Without scaling (-S) the fax is now centered on the page size specified with -H and/or -W. Before, fax2ps was using an obscure and practially useless algorithm to allocate the image relative to Letter sized paper which sometime sled to useless whitespace on the paper, while at the same time cutting of the faxes printable area at the opposite border. Second, scaling now preserves aspect ratio, which makes unusual faxes (in particular short ones) print properly. See http://bugzilla.remotesensing.org/show_bug.cgi?id=35 * tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by Bruce A. Mallett. See check message for detailed information on all the changes, including a faster encoder, fixes for level 2 PostScript, and support for the imagemask operator. 2001-03-27 Frank Warmerdam * libtiff/tiffio.h: Changed "#if LOGLUV_PUBLIC" to "#ifdef LOGLUV_PUBLIC" so it will work with VisualAge on AIX. http://bugzilla.remotesensing.org/show_bug.cgi?id=39 2001-03-16 Frank Warmerdam * tif_dirinfo.c: moved definition of copyright tag in field list. Apparently they have to be in sorted order by tag id. 2001-03-13 Frank Warmerdam * tif_getimage.c: Added support for 16bit minisblack/miniswhite images in RGBA interface. 2001-03-02 Frank Warmerdam * Added TIFFTAG_COPYRIGHT support. 2001-02-19 Frank Warmerdam * Brent Roman contributed updated tiffcp utility (and tiffcp.1) with support for extracting subimages with the ,n syntax, and also adding the -b bias removal flag. 2001-02-16 Frank Warmerdam * libtiff/libtiff.def: Brent Roman submitted new version adding serveral missing entry points. * libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS. Some sort of weird VMS thing. http://bugzilla.remotesensing.org/show_bug.cgi?id=31 * tif_luv.c/tiff.h/tiffio.h: New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward (greg@shutterfly.com). He writes: 1) I improved the gamut-mapping function in tif_luv.c for imaginary colors, because some images were being super-saturated on the input side and this resulted in some strange color shifts in the output. 2) I added a psuedotag in tiff.h to control random dithering during LogLuv encoding. This is turned off by default for 32-bit LogLuv and on for 24-bit LogLuv output. Dithering improves the average color accuracy over the image. 3) I added a #define for LOG_LUV_PUBLIC, which is enabled by default in tiffio.h, to expose internal routines for converting between LogLuv and XYZ coordinates. This is helpful for writing more efficient, specialized conversion routines, especially for reading LogLuv files. Changes applied with minor edits. 2001-01-23 Frank Warmerdam * tif_fax3.c: keep rw_mode flag internal to fax3 state to remember whether we are encoding or decoding. This is to ensure graceful recovery if TIFFClientOpen() discovers an attempt to open a compressed file for "r+" access, and subsequently close it, as it resets the tif_mode flag to O_RDONLY in this case to avoid writes, confusing the compressor's concept of whether it is in encode or decode mode. 2001-01-08 Mike Welles * Makefile.in: Now cleaning up after itself after creating the .tar.gz and .zip 2001-01-07 Frank Warmerdam * html/libtiff.html: Fixed arguments in example for TIFFRGBAImageGet() as per bug report by Patrick Connor. 2000-12-28 Frank Warmerdam * Added RELEASE-DATE file to release file list. * Fixed libtiff/makefile.vc to make tiffvers.h not version.h. 2000-12-22 Mike Welles * added link to CVS mirror from index.html * updated html/internals.html to note that LZW compression is not supported by default. 2000-12-22 Frank Warmerdam * updated html/libtiff.html to not point at Niles' old JPL web site for the man pages, point at www.libtiff.org. 2000-12-21 Frank Warmerdam * libtiff/tif_apple.c: Applied "Carbon" support patches supplied by Leonard Rosenthol . May interfere with correct building on older systems. If so, please let me know. 2000-12-19 Mike Welles * Took out LZW Encoding from tif_lzw.c * Created HOWTO-RELEASE * Created html/v3.5.6.html * updated index.html 2000-12-01 Frank Warmerdam * Added patches for EOFB support in tif_fax3.c and tif_fax3.h. Patches supplied by Frank Cringle Example file at: ftp://ftp.remotesensing.org/pub/libtiff/eofb_396.tif 2000-11-24 Frank Warmerdam * libtiff/Makefile.in: Added an installPrivateHdrs and install-private target so that the private headers required by libgeotiff can be installed with the others. They are not installed by default. * libtiff/Makefile.in: Added @MACHLIBDEPS@ to LINUXdso and GNULDdso targets so libtiff.so will be built with an explicit dependency on libm.so. * libtiff/Makefile.in: Use softlinks to link libtiff.so.3 to libtiff.so.3.5.5. * libtiff/Makefile.in & configure: Remove all references to the ALPHA file, or ALPHA version logic. Added stuff about DIST_POINT in place of DIST_TYPE and the alpha release number stuff. 2000-11-22 Frank Warmerdam * I have applied a patch from Steffen Moeller to the configure script so that it now accepts the --prefix, and --exec-prefix directives. 2000-11-13 Frank Warmerdam * I have made a variety of modifications in an effort to ensure the TIFFLIB_VERSION macro is automatically generated from the RELEASE-DATE file which seems to be updated regularly. o mkversion.c now reads RELEASE-DATE and emits TIFFLIB_VERSION in version include file. o renamed version.h to tiffvers.h because we now have to install it with the public libtiff include files. o include tiffvers.h in tiffio.h. o updated tif_version.c to use tiffvers.h. o Updated Makefile.in accordingly. * As per http://bugzilla.remotesensing.org/show_bug.cgi?id=25 I have updated the win32 detection rules in tiffcomp.h. 2000-10-20 Frank Warmerdam * tif_getimage.c: Fixed RGBA translation for YCbCr images for which the strip/tile width and height aren't multiples of the sampling size. See http://bugzilla.remotesensing.org/show_bug.cgi?id=20 Some patches from Rick LaMont of Dot C Software. * Modified tif_packbits.c encoder to avoid compressing more data than provided if rowsize doesn't factor into provided data (such as occurs for YCbCr). 2000-10-19 Frank Warmerdam * tools/rgb2ycbcr.c: fixed output strip size to account for vertical roundup if rows_per_strip not a multiple of vertical sample size. 2000-10-16 Frank Warmerdam * tif_dir.c: Clear TIFF_ISTILED flag in TIFFDefaultDirectory as per http://bugzilla.remotesensing.org/show_bug.cgi?id=18 from vandrove@vc.cvut.cz. * Modified tif_packbits.c decoding to avoid overrunning the output buffer, and to issue a warning if data needs to be discarded. See http://bugzilla.remotesensing.org/show_bug.cgi?id=18 2000-10-12 Frank Warmerdam * Modified tiff2bw to ensure portions add to 100%, and that white is properly recovered. See bug http://bugzilla.remotesensing.org/show_bug.cgi?id=15 Patch c/o Stanislav Brabec 2000-09-30 Frank Warmerdam * Modified TIFFClientOpen() to emit an error on an attempt to open a comperessed file for update (O_RDWR/r+) access. This is because the compressor/decompressor code gets very confused when the mode is O_RDWR, assuming this means writing only. See bug http://bugzilla.remotesensing.org/show_bug.cgi?id=13 2000-09-27 Frank Warmerdam * Added GNULDdso target an`d switched linux and freebsd to use it. 2000-09-26 Frank Warmerdam * Applied patch for 0x0000 sequences in tif_fax3.h's definition of EXPAND1D() as per bug 11 (from Roman). 2000-09-25 Frank Warmerdam * Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve cygwin compatibility. * Applied patch from Roman Shpount to tif_fax3.c. This seems to be a proper fix to the buffer sizing problem. See http://bugzilla.remotesensing.org/show_bug.cgi?id=11 * Fixed tif_getimage.c to fix overrun bug with YCbCr images without downsampling. http://bugzilla.remotesensing.org/show_bug.cgi?id=10 Thanks to Nick Lamb for reporting the bug and proving the patch. 2000-09-18 Frank Warmerdam * Fixed tif_jpeg.c so avoid destroying the decompressor before we are done access data thanks to bug report from: Michael Eckstein . * Reverted tif_flush change. 2000-09-14 Frank Warmerdam * tif_flush.c: Changed so that TIFFFlushData() doesn't return an error when TIFF_BEENWRITING is not set. This ensures that the directory contents can still be flushed by TIFFFlush(). 2000-08-14 Frank Warmerdam * tif_open.c: Don't set MMAP for O_RDWR files. * tif_open.c: Set STRIPCHOP_DEFAULT for O_RDWR as well as O_RDONLY so that files opened for update can be strip chopped too. * tif_read.c: fixed up bug with files missing rowsperstrip and the strips per separation fix done a few weeks ago. 2000-07-17 Frank Warmerdam * Tentatively added support for SAMPLEFORMAT_COMPLEXIEEEFP, and SAMPLEFORMAT_COMPLEXINT. 2000-07-13 Mike Welles * index.html, bugs.html: added bugzilla info. 2000-07-12 Frank Warmerdam * tif_read.c: fix subtle bug with determining the number of rows for strips that are the last strip in a separation but not the last strip of all in TIFFReadEncodedStrip(). * Applied 16/32 bit fix to tif_fax3.c. Fix supplied by Peter Skarpetis 2000-06-15 Frank Warmerdam * Modified tiffio.h logic with regard to including windows.h. It won't include it when building with __CYGWIN__. 2000-05-11 Frank Warmerdam * README: update to mention www.libtiff.org, don't list Sam's old email address. * configure: Fixed DSO test for Linux as per patch from Jan Van Buggenhout . 2000-04-21 Frank Warmerdam * libtiff/tif_dirread.c: Don't use estimate strip byte count for one tile/strip images with an offset, and byte count of zero.

Thanks to Stanislav Brabec * configure: fixed bugs in sed scripts (applied sed script s:/@:s;@:;s:/s;;:;: to configure). fix submitted to Stanislav Brabec * tools/iptcutil was not in files list, and wasn't being added to tar archive. Updated Makefile.in. 2000-03-17 Frank Warmerdam * tif_fax3.c: Fixed serious bug introduced during the uint16->uint32 conversion for the run arrays. 2000-03-03 Frank Warmerdam * Set td_sampleformat default to SAMPLEFORMAT_UINT instead of SAMPLEFORMAT_VOID in TIFFDefaultDirectory() in tif_dir.c. 2000-03-02 Frank Warmerdam * Added "GetDefaulted" support for TIFFTAG_SAMPLEFORMAT in tif_aux.c. * Patched tif_fax3.c so that dsp->runs is allocated a bit bigger to avoid overruns encountered with frle_bug.tif. Tue Feb 15 22:01:05 2000 Frank Warmerdam * Fixed tools/tiffcmp so that stopondiff testing works. Patch care of Joseph Orost . 2000-01-28 * Modified tif_unix.c to support 2-4GB seeks if USE_64BIT_API is set to 1, and added default (off) setting in tiffconf.h. This should eventually be set by the configure script somehow. The original work on all these 2-4GB changes was done by Peter Smith (psmith@creo.com). * Modified tif_win32.c to support 2-4GB seeks. * tentatively changed toff_t to be unsigned instead of signed to facilitate support for 2-4GB files. * Updated a variety of files to use toff_t. Fixed some mixups between toff_t and tsize_t. Fri Jan 28 10:13:49 2000 Frank Warmerdam * Largely reimplemented contrib/addtiffo to avoid temp files, updating the TIFF file in place. Fixed a few other bugs to. * Set tif_rawdatasize to zero when freeing raw data buffer in TIFFWriteDirectory(). * Enabled "REWRITE_HACK" in tif_write.c by default. * Fix bug in tif_write.c when switching between reading one directory and writing to another. * Made TIFFWriteCheck() public, and added TIFFCreateDirectory() Wed Jan 5 12:37:48 2000 Frank Warmerdam * Added TIFFmemory(3t) functions to libtiff.def. Tue Jan 4 13:39:00 2000 Frank Warmerdam * Added libtiff/libtiff.def to TIFFILES distribution list. Mon Dec 27 12:13:39 EST 1999 Mike Welles * Created lzw compression kit, as a new module (libtiff-lzw-compression-kit). * Altered descriptions in tools to reflect "by default" lzw not supported * Updated index.html to note lzw compression kit. Tue Dec 21 14:01:51 1999 Frank Warmerdam * Added fax3sm_winnt.c to distribution list in Makefile.in. Tue Dec 21 11:04:45 EST 1999 Mike Welles *** 3.5.4 release *** * Aadded Pixar tag support. Contributed by Phil Beffery * Made one more change to tif_dir.c for removal of LZW compression. Also added notice when LZW compression invoked. * Changed default compression in tools to TIFF_PACKBITS, and changed usage descriptions in tools to reflect removal of LZW compression Mon Dec 20 18:39:02 EST 1999 Mike Welles * Fixed bug that caused LZW (non) compression to segfault. Added warning about LZW compression removed being removed, and why. * Added nostrip to install in tools/Makefile.in so that debugging symbols are kept. Tue Dec 7 12:04:47 EST 1999 Mike Welles * Added patch from Ivo Penzar , supporting Adobe ZIP deflate. Untested. Sat Dec 4 15:47:11 1999 Frank Warmerdam * Made Packbits the default compression in tools/tiff2rgba.c instead of LZW. Tue Nov 30 14:41:43 1999 Frank Warmerdam *** 3.5.3. release *** * Added tif_luv to contrib/djgpp/Makefile.lib. Tue Nov 30 14:15:32 EST 1999 Mike Welles * Added zip creation to relase makefile target * Added html for TIFFWriteTile.3t man page. Tue Nov 30 09:20:16 1999 Frank Warmerdam * Added some changes to tif_write.c to support rewriting existing fixed sized tiles and strips. Code mods disabled by default, only enabled if REWRITE_HACK is defined for now. Mon Nov 29 11:43:42 1999 Frank Warmerdam * Added TIFFWriteTile.3t man page. Sun Nov 28 20:36:18 1999 Frank Warmerdam * Added notes on use of makefile.vc in build.html, and fixed email subscription address. 199-11-28 Mike Welles * Fixed apocalypse-inducing y2k bug in contrib/ras/ras2tiff.c * Did some casts cleaning up to reduce compiler warnings in tif_fax3.c, from Bruce Carmeron -- modifications of changes made by Frank (sun cc still complained on cast). * Added tiffconf.h to install target per request from Bill Radcliffe : "We need a way for ImageMagick to know features have been compiled into the TIFF library in order to handle things properly". Sat Nov 27 16:49:21 1999 Frank Warmerdam * fixed various VC++ warnings as suggested by Gilles Vollant . Wed Nov 24 12:08:16 1999 Frank Warmerdam * Modified TIFFquery.3t man pages info on TIFFIsByteSwapped() to not imply applications are responsible for image data swapping. 1999-11-22 Mike Welles * HTML-ized the man pages, added to html/man * Removed LZW Compression to comply with Unisys patent extortion. 1999-09-29 Mike Welles * Corrected one remaining 16 -> 32 bit value in tif_fax3.c, From Ivo Penzar 1999-09-26 Mike Welles *** 3.5.2 release *** * Corrected alpha versioning. * Removed distinction between alpha and release targets in Makefile.in. * added release.stamp target, which tags cvs tree, and updates "RELEASE-DATE" * added releasediff target, which diffs tree with source as of date in "RELEASE-DATE" * Ticked up version to 3.5.2 (alpha 01 -- but I think we'll moving away from alpha/non-alpha distinctions). * updated html to reflect release 1999-09-23 * Set O_BINARY for tif_unix.c open() ... used on cygwin for instance. * Added CYGWIN case in configure. Fri Sep 17 00:13:51 CEST 1999 Mike Welles * Applied Francois Dagand's patch to handle fax decompression bug. (sizes >= 65536 were failing) Tue Sep 14 21:31:43 1999 Frank Warmerdam * Applied "a" mode fix to tif_win32.c/TIFFOpen() as suggested by Christopher Lawton Wed Sep 8 08:19:18 1999 Frank Warmerdam * Added IRIX/gcc, and OSF/1 4.x support on behalf of Albert Chin-A-Young * Added TIFFReassignTagToIgnore() API on behalf of Bruce Cameron . Man page still pending. Wed Aug 25 11:39:07 1999 Frank Warmerdam * Added test target in Makefile, test_pics.sh script and pics/*.rpt files to provide for a rudimentary testsuite. * Added contrib/tags back from old distribution ... fixed up a bit. 1999-08-16 * Added simple makefile.vc makefiles for building with MS VC++ on Windows NT/98/95 in console mode. Stuff in contrib/win* make give better solutions for some users. Mon Aug 16 21:52:11 1999 Frank Warmerdam * Added addtiffo (add overviews to a TIFF file) in contrib. Didn't put it in tools since part of it is in C++. 1999-08-16 Michael L. Welles * Updated html/index.html with anon CVS instructions. Mon Aug 16 13:18:41 1999 Frank Warmerdam * pre-remove so link before softlink in LINUXdso action in libtiff/Makefile.in to avoid failure on LINUXdso builds other than the first. * Fixed problem with cvtcmap() in tif_getimage.c modifying the colormaps owned by the TIFF handle itself when trying to fixup wrong (eight bit) colormaps. Corrected by maintaining a private copy of the colormap. * Added TIFFReadRGBATile()/TIFFReadRGBAStrip() support in tif_getimage.c. * CVS Repository placed at remotesensing.org.

This decoder starts with an input stream, that is essentially the JpegInterchangeFormat stream, if any, followed by the strile data, if any. This stream is read in OJPEGReadByte and related functions. It analyzes the start of this stream, until it encounters non-marker data, i.e. compressed image data. Some of the header markers it sees have no actual content, like the SOI marker, and APP/COM markers that really shouldn't even be there. Some other markers do have content, and the valuable bits and pieces of information in these markers are saved, checking all to verify that the stream is more or less within expected bounds. This happens inside the OJPEGReadHeaderInfoSecStreamXxx functions. Some OJPEG imagery contains no valid JPEG header markers. This situation is picked up on if we've seen no SOF marker when we're at the start of the compressed image data. In this case, the tables are read from JpegXxxTables tags, and the other bits and pieces of information is initialized to its most basic value. This is implemented in the OJPEGReadHeaderInfoSecTablesXxx functions. When this is complete, a good and valid JPEG header can be assembled, and this is passed through to LibJpeg. When that's done, the remainder of the input stream, i.e. the compressed image data, can be passed through unchanged. This is done in OJPEGWriteStream functions. LibTiff rightly expects to know the subsampling values before decompression. Just like in new-style JPEG-in-TIFF, though, or even more so, actually, the YCbCrsubsampling tag is notoriously unreliable. To correct these tag values with the ones inside the JPEG stream, the first part of the input stream is pre-scanned in OJPEGSubsamplingCorrect, making no note of any other data, reporting no warnings or errors, up to the point where either these values are read, or it's clear they aren't there. This means that some of the data is read twice, but we feel speed in correcting these values is important enough to warrant this sacrifice. Allthough there is currently no define or other configuration mechanism to disable this behaviour, the actual header scanning is build to robustly respond with error report if it should encounter an uncorrected mismatch of subsampling values. See OJPEGReadHeaderInfoSecStreamSof. The restart interval and restart markers are the most tricky part... The restart interval can be specified in a tag. It can also be set inside the input JPEG stream. It can be used inside the input JPEG stream. If reading from strile data, we've consistenly discovered the need to insert restart markers in between the different striles, as is also probably the most likely interpretation of the original TIFF 6.0 specification. With all this setting of interval, and actual use of markers that is not predictable at the time of valid JPEG header assembly, the restart thing may turn out the Achilles heel of this implementation. Fortunately, most OJPEG writer vendors succeed in reading back what they write, which may be the reason why we've been able to discover ways that seem to work. Some special provision is made for planarconfig separate OJPEG files. These seem to consistently contain header info, a SOS marker, a plane, SOS marker, plane, SOS, and plane. This may or may not be a valid JPEG configuration, we don't know and don't care. We want LibTiff to be able to access the planes individually, without huge buffering inside LibJpeg, anyway. So we compose headers to feed to LibJpeg, in this case, that allow us to pass a single plane such that LibJpeg sees a valid single-channel JPEG stream. Locating subsequent SOS markers, and thus subsequent planes, is done inside OJPEGReadSecondarySos. The benefit of the scheme is... that it works, basically. We know of no other that does. It works without checking software tag, or otherwise going about things in an OJPEG flavor specific manner. Instead, it is a single scheme, that covers the cases with and without JpegInterchangeFormat, with and without striles, with part of the header in JpegInterchangeFormat and remainder in first strile, etc. It is forgiving and robust, may likely work with OJPEG flavors we've not seen yet, and makes most out of the data. Another nice side-effect is that a complete JPEG single valid stream is build if planarconfig is not separate (vast majority). We may one day use that to build converters to JPEG, and/or to new-style JPEG compression inside TIFF. A dissadvantage is the lack of random access to the individual striles. This is the reason for much of the complicated restart-and-position stuff inside OJPEGPreDecode. Applications would do well accessing all striles in order, as this will result in a single sequential scan of the input stream, and no restarting of LibJpeg decoding session. */ #define WIN32_LEAN_AND_MEAN #define VC_EXTRALEAN #include "tiffiop.h" #ifdef OJPEG_SUPPORT /* Configuration defines here are: * JPEG_ENCAP_EXTERNAL: The normal way to call libjpeg, uses longjump.

In the case of 8 and 16 bit values, the * input is assumed to be unsigned linear color values that represent * the range 0-1. In the case of IEEE values, the 0-1 range is assumed to * be the normal linear color range, in addition over 1 values are * accepted up to a value of about 25.0 to encode "hot" hightlights and such. * The encoding is lossless for 8-bit values, slightly lossy for the * other bit depths. The actual color precision should be better * than the human eye can perceive with extra room to allow for * error introduced by further image computation. As with any quantized * color format, it is possible to perform image calculations which * expose the quantization error. This format should certainly be less * susceptable to such errors than standard 8-bit encodings, but more * susceptable than straight 16-bit or 32-bit encodings. * * On reading the internal format is converted to the desired output format. * The program can request which format it desires by setting the internal * pseudo tag TIFFTAG_PIXARLOGDATAFMT to one of these possible values: * PIXARLOGDATAFMT_FLOAT = provide IEEE float values. * PIXARLOGDATAFMT_16BIT = provide unsigned 16-bit integer values * PIXARLOGDATAFMT_8BIT = provide unsigned 8-bit integer values * * alternately PIXARLOGDATAFMT_8BITABGR provides unsigned 8-bit integer * values with the difference that if there are exactly three or four channels * (rgb or rgba) it swaps the channel order (bgr or abgr). * * PIXARLOGDATAFMT_11BITLOG provides the internal encoding directly * packed in 16-bit values. However no tools are supplied for interpreting * these values. * * "hot" (over 1.0) areas written in floating point get clamped to * 1.0 in the integer data types. * * When the file is closed after writing, the bit depth and sample format * are set always to appear as if 8-bit data has been written into it. * That way a naive program unaware of the particulars of the encoding * gets the format it is most likely able to handle. * * The codec does it's own horizontal differencing step on the coded * values so the libraries predictor stuff should be turned off. * The codec also handle byte swapping the encoded values as necessary * since the library does not have the information necessary * to know the bit depth of the raw unencoded buffer. * * NOTE: This decoder does not appear to update tif_rawcp, and tif_rawcc. * This can cause problems with the implementation of CHUNKY_STRIP_READ_SUPPORT * as noted in http://trac.osgeo.org/gdal/ticket/3894.

"tiffiop.h" #ifdef LOGLUV_SUPPORT /* * TIFF Library. * LogLuv compression support for high dynamic range images. * * Contributed by Greg Larson. * * LogLuv image support uses the TIFF library to store 16 or 10-bit * log luminance values with 8 bits each of u and v or a 14-bit index. * * The codec can take as input and produce as output 32-bit IEEE float values * as well as 16-bit integer values. A 16-bit luminance is interpreted * as a sign bit followed by a 15-bit integer that is converted * to and from a linear magnitude using the transformation: * * L = 2^( (Le+.5)/256 - 64 ) # real from 15-bit * * Le = floor( 256*(log2(L) + 64) ) # 15-bit from real * * The actual conversion to world luminance units in candelas per sq. meter * requires an additional multiplier, which is stored in the TIFFTAG_STONITS. * This value is usually set such that a reasonable exposure comes from * clamping decoded luminances above 1 to 1 in the displayed image. * * The 16-bit values for u and v may be converted to real values by dividing * each by 32768. (This allows for negative values, which aren't useful as * far as we know, but are left in case of future improvements in human * color vision.) * * Conversion from (u,v), which is actually the CIE (u',v') system for * you color scientists, is accomplished by the following transformation: * * u = 4*x / (-2*x + 12*y + 3) * v = 9*y / (-2*x + 12*y + 3) * * x = 9*u / (6*u - 16*v + 12) * y = 4*v / (6*u - 16*v + 12) * * This process is greatly simplified by passing 32-bit IEEE floats * for each of three CIE XYZ coordinates. The codec then takes care * of conversion to and from LogLuv, though the application is still * responsible for interpreting the TIFFTAG_STONITS calibration factor. * * By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white * point of (x,y)=(1/3,1/3). However, most color systems assume some other * white point, such as D65, and an absolute color conversion to XYZ then * to another color space with a different white point may introduce an * unwanted color cast to the image. It is often desirable, therefore, to * perform a white point conversion that maps the input white to [1 1 1] * in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT * tag value. A decoder that demands absolute color calibration may use * this white point tag to get back the original colors, but usually it * will be ignored and the new white point will be used instead that * matches the output color space. * * Pixel information is compressed into one of two basic encodings, depending * on the setting of the compression tag, which is one of COMPRESSION_SGILOG * or COMPRESSION_SGILOG24. For COMPRESSION_SGILOG, greyscale data is * stored as: * * 1 15 * |-+---------------| * * COMPRESSION_SGILOG color data is stored as: * * 1 15 8 8 * |-+---------------|--------+--------| * S Le ue ve * * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as: * * 10 14 * |----------|--------------| * Le' Ce * * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is * encoded as an index for optimal color resolution. The 10 log bits are * defined by the following conversions: * * L = 2^((Le'+.5)/64 - 12) # real from 10-bit * * Le' = floor( 64*(log2(L) + 12) ) # 10-bit from real * * The 10 bits of the smaller format may be converted into the 15 bits of * the larger format by multiplying by 4 and adding 13314. Obviously, * a smaller range of magnitudes is covered (about 5 orders of magnitude * instead of 38), and the lack of a sign bit means that negative luminances * are not allowed. (Well, they aren't allowed in the real world, either, * but they are useful for certain types of image processing.) * * The desired user format is controlled by the setting the internal * pseudo tag TIFFTAG_SGILOGDATAFMT to one of: * SGILOGDATAFMT_FLOAT = IEEE 32-bit float XYZ values * SGILOGDATAFMT_16BIT = 16-bit integer encodings of logL, u and v * Raw data i/o is also possible using: * SGILOGDATAFMT_RAW = 32-bit unsigned integer with encoded pixel * In addition, the following decoding is provided for ease of display: * SGILOGDATAFMT_8BIT = 8-bit default RGB gamma-corrected values * * For grayscale images, we provide the following data formats: * SGILOGDATAFMT_FLOAT = IEEE 32-bit float Y values * SGILOGDATAFMT_16BIT = 16-bit integer w/ encoded luminance * SGILOGDATAFMT_8BIT = 8-bit gray monitor values * * Note that the COMPRESSION_SGILOG applies a simple run-length encoding * scheme by separating the logL, u and v bytes for each row and applying * a PackBits type of compression. Since the 24-bit encoding is not * adaptive, the 32-bit color format takes less space in many cases. * * Further control is provided over the conversion from higher-resolution * formats to final encoded values through the pseudo tag * TIFFTAG_SGILOGENCODE: * SGILOGENCODE_NODITHER = do not dither encoded values * SGILOGENCODE_RANDITHER = apply random dithering during encoding * * The default value of this tag is SGILOGENCODE_NODITHER for * COMPRESSION_SGILOG to maximize run-length encoding and * SGILOGENCODE_RANDITHER for COMPRESSION_SGILOG24 to turn * quantization errors into noise. */ #include #include #include /* * State block for each open TIFF * file using LogLuv compression/decompression. */ typedef struct logLuvState LogLuvState;

It dnl sets the PTHREAD_LIBS output variable to the threads library and linker dnl flags, and the PTHREAD_CFLAGS output variable to any special C compiler dnl flags that are needed. (The user can also force certain compiler dnl flags/libs to be tested by setting these environment variables.) dnl dnl Also sets PTHREAD_CC to any special C compiler that is needed for dnl multi-threaded programs (defaults to the value of CC otherwise). (This dnl is necessary on AIX to use the special cc_r compiler alias.) dnl dnl NOTE: You are assumed to not only compile your program with these flags, dnl but also link it with them as well. e.g. you should link with dnl $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS dnl dnl If you are only building threads programs, you may wish to use these dnl variables in your default LIBS, CFLAGS, and CC: dnl dnl LIBS="$PTHREAD_LIBS $LIBS" dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS" dnl CC="$PTHREAD_CC" dnl dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant dnl has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name dnl (e.g. PTHREAD_CREATE_UNDETACHED on AIX). dnl dnl ACTION-IF-FOUND is a list of shell commands to run if a threads library dnl is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it dnl is not found. If ACTION-IF-FOUND is not specified, the default action dnl will define HAVE_PTHREAD. dnl dnl Please let the authors know if this macro fails on any platform, or if dnl you have any other suggestions or comments. This macro was based on work dnl by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help dnl from M. Frigo), as well as ac_pthread and hb_pthread macros posted by dnl Alejandro Forero Cuervo to the autoconf macro repository.

libtiff is a set of C functions (a library) that support the manipulation of TIFF image files. The library requires an ANSI C compilation environment for building and presumes an ANSI C environment for use.


libtiff provides interfaces to image data at several layers of abstraction (and cost). At the highest level image data can be read into an 8-bit/sample, ABGR pixel raster format without regard for the underlying data organization, colorspace, or compression scheme. Below this high-level interface the library provides scanline-, strip-, and tile-oriented interfaces that return data decompressed but otherwise untransformed. These interfaces require that the application first identify the organization of stored data and select either a strip-based or tile-based API for manipulating data. At the lowest level the library provides access to the raw uncompressed strips or tiles, returning the data exactly as it appears in the file.

The material presented in this chapter is a basic introduction to the capabilities of the library; it is not an attempt to describe everything a developer needs to know about the library or about TIFF. Detailed information on the interfaces to the library are given in the UNIX manual pages that accompany this software.

Michael Still has also written a useful introduction to libtiff for the IBM DeveloperWorks site available at http://www.ibm.com/developerworks/linux/library/l-libtiff.

The following sections are found in this chapter:

How to tell which version you have

The software version can be found by looking at the file named VERSION that is located at the top of the source tree; the precise alpha number is given in the file dist/tiff.alpha. If you have need to refer to this specific software, you should identify it as:

TIFF <version> <alpha>

where <version> is whatever you get from "cat VERSION" and <alpha> is what you get from "cat dist/tiff.alpha".

Within an application that uses libtiff the TIFFGetVersion routine will return a pointer to a string that contains software version information. The library include file <tiffio.h> contains a C pre-processor define TIFFLIB_VERSION that can be used to check library version compatiblity at compile time.

Library Datatypes

libtiff defines a portable programming interface through the use of a set of C type definitions. These definitions, defined in in the files tiff.h and tiffio.h, isolate the libtiff API from the characteristics of the underlying machine. To insure portable code and correct operation, applications that use libtiff should use the typedefs and follow the function prototypes for the library API.

Memory Management

libtiff uses a machine-specific set of routines for managing dynamically allocated memory. _TIFFmalloc, _TIFFrealloc, and _TIFFfree mimic the normal ANSI C routines. Any dynamically allocated memory that is to be passed into the library should be allocated using these interfaces in order to insure pointer compatibility on machines with a segmented architecture. (On 32-bit UNIX systems these routines just call the normal malloc, realloc, and free routines in the C library.)

To deal with segmented pointer issues libtiff also provides _TIFFmemcpy, _TIFFmemset, and _TIFFmemmove routines that mimic the equivalent ANSI C routines, but that are intended for use with memory allocated through _TIFFmalloc and _TIFFrealloc.

Error Handling

libtiff handles most errors by returning an invalid/erroneous value when returning from a function call. Various diagnostic messages may also be generated by the library. All error messages are directed to a single global error handler routine that can be specified with a call to TIFFSetErrorHandler. Likewise warning messages are directed to a single handler routine that can be specified with a call to TIFFSetWarningHandler

Basic File Handling

The library is modeled after the normal UNIX stdio library. For example, to read from an existing TIFF image the file must first be opened:

#include "tiffio.h"
main()
{
    TIFF* tif = TIFFOpen("foo.tif", "r");
    ... do stuff ...
    TIFFClose(tif);
}

The handle returned by TIFFOpen is opaque, that is the application is not permitted to know about its contents. All subsequent library calls for this file must pass the handle as an argument.

To create or overwrite a TIFF image the file is also opened, but with a "w" argument:

#include "tiffio.h"
main()
{
    TIFF* tif = TIFFOpen("foo.tif", "w");
    ... do stuff ...
    TIFFClose(tif);
}

If the file already exists it is first truncated to zero length.

Note that unlike the stdio library TIFF image files may not be opened for both reading and writing; there is no support for altering the contents of a TIFF file.

libtiff buffers much information associated with writing a valid TIFF image. Consequently, when writing a TIFF image it is necessary to always call TIFFClose or TIFFFlush to flush any buffered information to a file. Note that if you call TIFFClose you do not need to call TIFFFlush.

TIFF Directories

TIFF supports the storage of multiple images in a single file. Each image has an associated data structure termed a directory that houses all the information about the format and content of the image data. Images in a file are usually related but they do not need to be; it is perfectly alright to store a color image together with a black and white image. Note however that while images may be related their directories are not. That is, each directory stands on its own; their is no need to read an unrelated directory in order to properly interpret the contents of an image.

libtiff provides several routines for reading and writing directories. In normal use there is no need to explicitly read or write a directory: the library automatically reads the first directory in a file when opened for reading, and directory information to be written is automatically accumulated and written when writing (assuming TIFFClose or TIFFFlush are called).

For a file open for reading the TIFFSetDirectory routine can be used to select an arbitrary directory; directories are referenced by number with the numbering starting at 0. Otherwise the TIFFReadDirectory and TIFFWriteDirectory routines can be used for sequential access to directories. For example, to count the number of directories in a file the following code might be used:

#include "tiffio.h"
main(int argc, char* argv[])
{
    TIFF* tif = TIFFOpen(argv[1], "r");
    if (tif) {
        int dircount = 0;
        do {
            dircount++;
        } while (TIFFReadDirectory(tif));
        printf("%d directories in %s\n", dircount, argv[1]);
        TIFFClose(tif);
    }
    exit(0);
}

Finally, note that there are several routines for querying the directory status of an open file: TIFFCurrentDirectory returns the index of the current directory and TIFFLastDirectory returns an indication of whether the current directory is the last directory in a file. There is also a routine, TIFFPrintDirectory, that can be called to print a formatted description of the contents of the current directory; consult the manual page for complete details.

TIFF Tags

Image-related information such as the image width and height, number of samples, orientation, colorimetric information, etc. are stored in each image directory in fields or tags. Tags are identified by a number that is usually a value registered with the Aldus (now Adobe) Corporation. Beware however that some vendors write TIFF images with tags that are unregistered; in this case interpreting their contents is usually a waste of time.

libtiff reads the contents of a directory all at once and converts the on-disk information to an appropriate in-memory form. While the TIFF specification permits an arbitrary set of tags to be defined and used in a file, the library only understands a limited set of tags. Any unknown tags that are encountered in a file are ignored. There is a mechanism to extend the set of tags the library handles without modifying the library itself; this is described elsewhere.

libtiff provides two interfaces for getting and setting tag values: TIFFGetField and TIFFSetField. These routines use a variable argument list-style interface to pass parameters of different type through a single function interface. The get interface takes one or more pointers to memory locations where the tag values are to be returned and also returns one or zero according to whether the requested tag is defined in the directory. The set interface takes the tag values either by-reference or by-value. The TIFF specification defines default values for some tags. To get the value of a tag, or its default value if it is undefined, the TIFFGetFieldDefaulted interface may be used.

The manual pages for the tag get and set routines specifiy the exact data types and calling conventions required for each tag supported by the library.

TIFF Compression Schemes

libtiff includes support for a wide variety of data compression schemes. In normal operation a compression scheme is automatically used when the TIFF Compression tag is set, either by opening a file for reading, or by setting the tag when writing.

Compression schemes are implemented by software modules termed codecs that implement decoder and encoder routines that hook into the core library i/o support. Codecs other than those bundled with the library can be registered for use with the TIFFRegisterCODEC routine. This interface can also be used to override the core-library implementation for a compression scheme.

Byte Order

The TIFF specification says, and has always said, that a correct TIFF reader must handle images in big-endian and little-endian byte order. libtiff conforms in this respect. Consequently there is no means to force a specific byte order for the data written to a TIFF image file (data is written in the native order of the host CPU unless appending to an existing file, in which case it is written in the byte order specified in the file).

Data Placement

The TIFF specification requires that all information except an 8-byte header can be placed anywhere in a file. In particular, it is perfectly legitimate for directory information to be written after the image data itself. Consequently TIFF is inherently not suitable for passing through a stream-oriented mechanism such as UNIX pipes. Software that require that data be organized in a file in a particular order (e.g. directory information before image data) does not correctly support TIFF. libtiff provides no mechanism for controlling the placement of data in a file; image data is typically written before directory information.

TIFFRGBAImage Support

libtiff provides a high-level interface for reading image data from a TIFF file. This interface handles the details of data organization and format for a wide variety of TIFF files; at least the large majority of those files that one would normally encounter. Image data is, by default, returned as ABGR pixels packed into 32-bit words (8 bits per sample). Rectangular rasters can be read or data can be intercepted at an intermediate level and packed into memory in a format more suitable to the application. The library handles all the details of the format of data stored on disk and, in most cases, if any colorspace conversions are required: bilevel to RGB, greyscale to RGB, CMYK to RGB, YCbCr to RGB, 16-bit samples to 8-bit samples, associated/unassociated alpha, etc.

There are two ways to read image data using this interface. If all the data is to be stored in memory and manipulated at once, then the routine TIFFReadRGBAImage can be used:

#include "tiffio.h"
main(int argc, char* argv[])
{
    TIFF* tif = TIFFOpen(argv[1], "r");
    if (tif) {
        uint32 w, h;
        size_t npixels;
        uint32* raster;
        
        TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &w);
        TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &h);
        npixels = w * h;
        raster = (uint32*) _TIFFmalloc(npixels * sizeof (uint32));
        if (raster != NULL) {
            if (TIFFReadRGBAImage(tif, w, h, raster, 0)) {
                ...process raster data...
            }
            _TIFFfree(raster);
        }
        TIFFClose(tif);
    }
    exit(0);
}

Note above that _TIFFmalloc is used to allocate memory for the raster passed to TIFFReadRGBAImage; this is important to insure the ``appropriate type of memory'' is passed on machines with segmented architectures.

Alternatively, TIFFReadRGBAImage can be replaced with a more low-level interface that permits an application to have more control over this reading procedure. The equivalent to the above is:

#include "tiffio.h"
main(int argc, char* argv[])
{
    TIFF* tif = TIFFOpen(argv[1], "r");
    if (tif) {
        TIFFRGBAImage img;
        char emsg[1024];
        
        if (TIFFRGBAImageBegin(&img, tif, 0, emsg)) {
            size_t npixels;
            uint32* raster;
            
            npixels = img.width * img.height;
            raster = (uint32*) _TIFFmalloc(npixels * sizeof (uint32));
            if (raster != NULL) {
                if (TIFFRGBAImageGet(&img, raster, img.width, img.height)) {
                    ...process raster data...
                }
                _TIFFfree(raster);
            }
            TIFFRGBAImageEnd(&img);
        } else
            TIFFError(argv[1], emsg);
        TIFFClose(tif);
    }
    exit(0);
}

However this usage does not take advantage of the more fine-grained control that's possible. That is, by using this interface it is possible to:

  • repeatedly fetch (and manipulate) an image without opening and closing the file
  • interpose a method for packing raster pixel data according to application-specific needs (or write the data at all)
  • interpose methods that handle TIFF formats that are not already handled by the core library

The first item means that, for example, image viewers that want to handle multiple files can cache decoding information in order to speedup the work required to display a TIFF image.

The second item is the main reason for this interface. By interposing a "put method" (the routine that is called to pack pixel data in the raster) it is possible share the core logic that understands how to deal with TIFF while packing the resultant pixels in a format that is optimized for the application. This alternate format might be very different than the 8-bit per sample ABGR format the library writes by default. For example, if the application is going to display the image on an 8-bit colormap display the put routine might take the data and convert it on-the-fly to the best colormap indices for display.

The last item permits an application to extend the library without modifying the core code. By overriding the code provided an application might add support for some esoteric flavor of TIFF that it needs, or it might substitute a packing routine that is able to do optimizations using application/environment-specific information.

The TIFF image viewer found in tools/sgigt.c is an example of an application that makes use of the TIFFRGBAImage support.

Scanline-based Image I/O

The simplest interface provided by libtiff is a scanline-oriented interface that can be used to read TIFF images that have their image data organized in strips (trying to use this interface to read data written in tiles will produce errors.) A scanline is a one pixel high row of image data whose width is the width of the image. Data is returned packed if the image data is stored with samples packed together, or as arrays of separate samples if the data is stored with samples separated. The major limitation of the scanline-oriented interface, other than the need to first identify an existing file as having a suitable organization, is that random access to individual scanlines can only be provided when data is not stored in a compressed format, or when the number of rows in a strip of image data is set to one (RowsPerStrip is one).

Two routines are provided for scanline-based i/o: TIFFReadScanline and TIFFWriteScanline. For example, to read the contents of a file that is assumed to be organized in strips, the following might be used:

#include "tiffio.h"
main()
{
    TIFF* tif = TIFFOpen("myfile.tif", "r");
    if (tif) {
        uint32 imagelength;
        tdata_t buf;
        uint32 row;
        
        TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &imagelength);
        buf = _TIFFmalloc(TIFFScanlineSize(tif));
        for (row = 0; row < imagelength; row++)
            tiffreadscanline(tif, buf, row);
        _tifffree(buf);
        tiffclose(tif);
    }
}

TIFFScanlineSize returns the number of bytes in a decoded scanline, as returned by TIFFReadScanline. Note however that if the file had been create with samples written in separate planes, then the above code would only read data that contained the first sample of each pixel; to handle either case one might use the following instead:

#include "tiffio.h"
main()
{
    TIFF* tif = TIFFOpen("myfile.tif", "r");
    if (tif) {
        uint32 imagelength;
        tdata_t buf;
        uint32 row;
        
        TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &imagelength);
        TIFFGetField(tif, TIFFTAG_PLANARCONFIG, &config);
        buf = _TIFFmalloc(TIFFScanlineSize(tif));
        if (config == PLANARCONFIG_CONTIG) {
            for (row = 0; row < imagelength; row++)
                tiffreadscanline(tif, buf, row);
        } else if (config == planarconfig_separate) {
            uint16 s, nsamples;
            
            tiffgetfield(tif, tifftag_samplesperpixel, &nsamples);
            for (s = 0; s < nsamples; s++)
                for (row = 0; row < imagelength; row++)
                    tiffreadscanline(tif, buf, row, s);
        }
        _tifffree(buf);
        tiffclose(tif);
    }
}

Beware however that if the following code were used instead to read data in the case PLANARCONFIG_SEPARATE,...

            for (row = 0; row < imagelength; row++)
                for (s = 0; s < nsamples; s++)
                    tiffreadscanline(tif, buf, row, s);

...then problems would arise if RowsPerStrip was not one because the order in which scanlines are requested would require random access to data within strips (something that is not supported by the library when strips are compressed).

Strip-oriented Image I/O

The strip-oriented interfaces provided by the library provide access to entire strips of data. Unlike the scanline-oriented calls, data can be read or written compressed or uncompressed. Accessing data at a strip (or tile) level is often desirable because there are no complications with regard to random access to data within strips.

A simple example of reading an image by strips is:

#include "tiffio.h"
main()
{
    TIFF* tif = TIFFOpen("myfile.tif", "r");
    if (tif) {
        tdata_t buf;
        tstrip_t strip;
        
        buf = _TIFFmalloc(TIFFStripSize(tif));
        for (strip = 0; strip < tiffnumberofstrips(tif); strip++)
            tiffreadencodedstrip(tif, strip, buf, (tsize_t) -1);
        _tifffree(buf);
        tiffclose(tif);
    }
}

Notice how a strip size of -1 is used; TIFFReadEncodedStrip will calculate the appropriate size in this case.

The above code reads strips in the order in which the data is physically stored in the file. If multiple samples are present and data is stored with PLANARCONFIG_SEPARATE then all the strips of data holding the first sample will be read, followed by strips for the second sample, etc.

Finally, note that the last strip of data in an image may have fewer rows in it than specified by the RowsPerStrip tag. A reader should not assume that each decoded strip contains a full set of rows in it.

The following is an example of how to read raw strips of data from a file:

#include "tiffio.h"
main()
{
    TIFF* tif = TIFFOpen("myfile.tif", "r");
    if (tif) {
        tdata_t buf;
        tstrip_t strip;
        uint32* bc;
        uint32 stripsize;
        
        TIFFGetField(tif, TIFFTAG_STRIPBYTECOUNTS, &bc);
        stripsize = bc[0];
        buf = _TIFFmalloc(stripsize);
        for (strip = 0; strip < tiffnumberofstrips(tif); strip++) {
            if (bc[strip] > stripsize) {
                buf = _TIFFrealloc(buf, bc[strip]);
                stripsize = bc[strip];
            }
            TIFFReadRawStrip(tif, strip, buf, bc[strip]);
        }
        _TIFFfree(buf);
        TIFFClose(tif);
    }
}

As above the strips are read in the order in which they are physically stored in the file; this may be different from the logical ordering expected by an application.

Tile-oriented Image I/O

Tiles of data may be read and written in a manner similar to strips. With this interface, an image is broken up into a set of rectangular areas that may have dimensions less than the image width and height. All the tiles in an image have the same size, and the tile width and length must each be a multiple of 16 pixels. Tiles are ordered left-to-right and top-to-bottom in an image. As for scanlines, samples can be packed contiguously or separately. When separated, all the tiles for a sample are colocated in the file. That is, all the tiles for sample 0 appear before the tiles for sample 1, etc.

Tiles and strips may also be extended in a z dimension to form volumes. Data volumes are organized as "slices". That is, all the data for a slice is colocated. Volumes whose data is organized in tiles can also have a tile depth so that data can be organized in cubes.

There are actually two interfaces for tiles. One interface is similar to scanlines, to read a tiled image, code of the following sort might be used:

main()
{
    TIFF* tif = TIFFOpen("myfile.tif", "r");
    if (tif) {
        uint32 imageWidth, imageLength;
        uint32 tileWidth, tileLength;
        uint32 x, y;
        tdata_t buf;
        
        TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &imageWidth);
        TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &imageLength);
        TIFFGetField(tif, TIFFTAG_TILEWIDTH, &tileWidth);
        TIFFGetField(tif, TIFFTAG_TILELENGTH, &tileLength);
        buf = _TIFFmalloc(TIFFTileSize(tif));
        for (y = 0; y < imagelength; y += tilelength)
            for (x = 0; x < imagewidth; x += tilewidth)
                tiffreadtile(tif, buf, x, y, 0);
        _tifffree(buf);
        tiffclose(tif);
    }
}

(once again, we assume samples are packed contiguously.)

Alternatively a direct interface to the low-level data is provided a la strips. Tiles can be read with TIFFReadEncodedTile or TIFFReadRawTile, and written with TIFFWriteEncodedTile or TIFFWriteRawTile. For example, to read all the tiles in an image:

#include "tiffio.h"
main()
{
    TIFF* tif = TIFFOpen("myfile.tif", "r");
    if (tif) {
        tdata_t buf;
        ttile_t tile;
        
        buf = _TIFFmalloc(TIFFTileSize(tif));
        for (tile = 0; tile < tiffnumberoftiles(tif); tile++)
            tiffreadencodedtile(tif, tile, buf, (tsize_t) -1);
        _tifffree(buf);
        tiffclose(tif);
    }
}

Some other stuff will almost certainly go here...

This software provides support for the Tag Image File Format (TIFF), a widely used format for storing image data. The latest version of the TIFF specification is available on-line in several different formats.

Included in this software distribution is a library, libtiff, for reading and writing TIFF, a small collection of tools for doing simple manipulations of TIFF images, and documentation on the library and tools. Libtiff is a portable software, it was built and tested on various systems: UNIX flavors (Linux, BSD, Solaris, MacOS X), Windows, and OpenVMS. It should be possible to port libtiff and additional tools on other OSes.

The library, along with associated tool programs, should handle most of your needs for reading and writing TIFF images on 32- and 64-bit machines.

The software was originally authored and maintained by Sam Leffler.

Questions should be sent to the TIFF mailing list: tiff@lists.maptools.org, with a subscription interface at http://lists.maptools.org/mailman/listinfo/tiff.

The persons responsible for putting up this site and putting together versions >= 3.5.1 are Frank Warmerdam, Andrey Kiselev, Bob Friesenhahn, Joris Van Damme and Lee Howard.

Custom Tag Support

The approach to extending libtiff with custom tags has changed radically. Previously, all internally supported TIFF tags had a place in the private TIFFDirectory structure within libtiff to hold the values (if read), and a "field number" (ie. FIELD_SUBFILETYPE) used to identify that tag. However, every time a new tag was added to the core, the size of the TIFFDirectory structure would changing, breaking any dynamically linked software that used the private data structures.

Also, any tag not recognised by libtiff would not be read and accessable to applications without some fairly complicated work on the applications part to pre-register the tags as exemplified by the support for "Geo"TIFF tags by libgeotiff layered on libtiff.

Amoung other things this approach required the extension code to access the private libtiff structures ... which made the higher level non-libtiff code be locked into a specific version of libtiff at compile time. This caused no end of bug reports!

The new approach is for libtiff to read all tags from TIFF files. Those that aren't recognised as "core tags" (those having an associated FIELD_ value, and place for storage in the TIFFDirectory structure) are now read into a dynamic list of extra tags (td_customValues in TIFFDirectory). When a new tag code is encountered for the first time in a given TIFF file, a new anonymous tag definition is created for the tag in the tag definition list. The type, and some other metadata is worked out from the instance encountered. These fields are known as "custom tags".

Custom tags can be set and fetched normally using TIFFSetField() and TIFFGetField(), and appear pretty much like normal tags to application code. However, they have no impact on internal libtiff processing (such as compression). Some utilities, such as tiffcp will now copy these custom tags to the new output files.

As well as the internal work with custom tags, new C API entry points were added so that extension libraries, such as libgeotiff, could define new tags more easily without accessing internal data structures. Because tag handling of extension tags is done via the "custom fields" mechanism as well, the definition provided externally mostly serves to provide a meaningful name for the tag. The addition of "custom tags" and the altered approach to extending libtiff with externally defined tags is the primary reason for the shift to the 3.6.x version number from 3.5.x.

  • libtiff/tif_open.c: Pointers to custom procedures in TIFFClientOpen() are checked to be not NULL-pointers.
  • libtiff/tif_lzw.c: Assertions in LZWDecode and LZWDecodeCompat replaced by warnings. Now libtiff should read corrupted LZW-compressed files by skipping bad strips as per bug 100.
  • libtiff/: tif_dirwrite.c, tif_write.c, tiffio.h: TIFFCheckpointDirectory() routine added as per bug 124. The TIFFWriteDirectory man page discusses this new function as well as the related TIFFRewriteDirectory().
  • libtiff/: tif_codec.c, tif_compress.c, tiffiop.h, tif_getimage.c: Introduced additional members tif->tif_decodestatus and tif->tif_encodestatus for correct handling of unconfigured codecs (we should not try to read data or to define data size without correct codecs). See bug 119.
  • tif_dirread.c: avoid div-by-zero if rowbytes is zero in chop func as per bug 111.
  • libtiff/: tiff.h, tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c, tif_dirwrite.c: Dwight Kelly added get/put code for new tag XMLPACKET as defined in Adobe XMP Technote. Added missing INKSET tag value from TIFF 6.0 spec INKSET_MULTIINK (=2). Added missing tags from Adobe TIFF technotes: CLIPPATH, XCLIPPATHUNITS, YCLIPPATHUNITS, OPIIMAGEID, OPIPROXY and INDEXED. Added PHOTOMETRIC tag value from TIFF technote 4 ICCLAB (=9).
  • libtiff/tif_getimage.c: Additional check for supported codecs added in TIFFRGBAImageOK, TIFFReadRGBAImage, TIFFReadRGBAStrip and TIFFReadRGBATile now use TIFFRGBAImageOK before reading a per bug 110.
  • libtiff/: tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c, tif_dirwrite.c: Added routine TIFFDataWidth for determining TIFFDataType sizes instead of working with tiffDataWidth array directly as per bug 109.
  • libtiff/: tif_dirinfo.c, tif_dirwrite.c: Added possibility to read broken TIFFs with LONG type used for TIFFTAG_COMPRESSION, TIFFTAG_BITSPERSAMPLE, TIFFTAG_PHOTOMETRIC as per bug 99.
  • libtiff/{tiff.h,tif_fax3.c}: Add support for __arch64__ as per bug 94.
  • libtiff/tif_read.c: Fixed TIFFReadEncodedStrip() to fail if the decodestrip function returns anything not greater than zero as per bug 97.
  • libtiff/tif_jpeg.c: fixed computation of segment_width for tiles files to avoid error about it not matching the cinfo.d.image_width values ("JPEGPreDecode: Improper JPEG strip/tile size.") for ITIFF files. Apparently the problem was incorporated since 3.5.5, presumably during the OJPEG/JPEG work recently.
  • libtiff/tif_getimage.c: If DEFAULT_EXTRASAMPLE_AS_ALPHA is 1 (defined in tiffconf.h - 1 by default) then the RGBA interface will assume that a fourth extra sample is ASSOCALPHA if the EXTRASAMPLE value isn't set for it. This changes the behaviour of the library, but makes it work better with RGBA files produced by lots of applications that don't mark the alpha values properly. As per bugs 93 and 65.
  • libtiff/tif_jpeg.c: allow jpeg data stream sampling values to override those from tiff directory. This makes this work with ImageGear generated files.

This document describes the changes made to the software between the previous and current versions (see above). If you don't find something listed here, then it was not done in this timeframe, or it was not considered important enough to be mentioned. The following information is located here:

CHANGES IN THE SOFTWARE CONFIGURATION:
  • configure now captures significantly more information in the config.log file and provides more information when it is unable to setup a configuration
  • support was added for building shared libraries on more systems: AIX, HPUX, Solaris, and Linux.
  • a new configuration parameter LIBCOPTS was added for passing arguments to the C compiler to use when building only the library; this is part of the enhanced support for building shared libraries
  • include files for optional packages that reside in /usr/include are now handled correctly
  • build trees may now be configured using either relative or absolute pathnames to the source distribution
  • several new configuration parameters were added, mainly for building shared libraries: DIST_MAJOR, DIST_MINOR, DIST_ALPHA, and DSOSUF_VERSION

CHANGES IN LIBTIFF:
  • the Deflate support has been revised: it requires version 0.99 of the zlib software distribution, the output format has changed and is incompatible with previous versions of this library (each strip now includes a header read and written by the zlib library)
  • the codec name printed by the TIFFPrintDirectory routine is now taken from the codec table instead of from a builtin table; this means that application-defined codecs are handled correctly
  • a new symbol was added that contains the library version number; this can be used to do a compile-time compatibility check of the library version

CHANGES IN THE MANUAL PAGES:
  • the creation and installation of manual pages was redone; it now implements the documented ``configuration scheme''
TIFF home page.

MAJOR CHANGES:
  • Bug-fix release.

CHANGES IN THE SOFTWARE CONFIGURATION:

CHANGES IN LIBTIFF:
  • tif_strip.c: Take subsampling in account when calculating TIFFScanlineSize().
  • tif_jpeg.c, tif_fax3.c, tif_zip.c, tif_pixarlog.c, tif_lzw.c, tif_luv.c: Use _TIFFSetDefaultCompressionState() in all codec cleanup methods. As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1120
  • tif_jpeg.c: Do not cleanup codec state in TIFFInitJPEG(). As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1119

Introduction to the TIFF Documentation

The following definitions are used throughout this documentation. They are consistent with the terminology used in the TIFF 6.0 specification.

Sample
The unit of information stored in an image; often called a channel elsewhere. Sample values are numbers, usually unsigned integers, but possibly in some other format if the SampleFormat tag is specified in a TIFF
Pixel
A collection of one or more samples that go together.
Row
An Nx1 rectangular collection of pixels.
Tile
An NxM rectangular organization of data (or pixels).
Strip
A tile whose width is the full image width.
Compression
A scheme by which pixel or sample data are stored in an encoded form, specifically with the intent of reducing the storage cost.
Codec
Software that implements the decoding and encoding algorithms of a compression scheme.

In order to better understand how TIFF works (and consequently this software) it is important to recognize the distinction between the physical organization of image data as it is stored in a TIFF and how the data is interpreted and manipulated as pixels in an image. TIFF supports a wide variety of storage and data compression schemes that can be used to optimize retrieval time and/or minimize storage space. These on-disk formats are independent of the image characteristics; it is the responsibility of the TIFF reader to process the on-disk storage into an in-memory format suitable for an application. Furthermore, it is the responsibility of the application to properly interpret the visual characteristics of the image data. TIFF defines a framework for specifying the on-disk storage format and image characteristics with few restrictions. This permits significant complexity that can be daunting. Good applications that handle TIFF work by handling as wide a range of storage formats as possible, while constraining the acceptable image characteristics to those that make sense for the application.

NAME

TIFFReadRGBAStrip − read and decode an image strip into a fixed-format raster

SYNOPSIS

#include <tiffio.h>

#define TIFFGetR(abgr) ((abgr) & 0xff)
#define TIFFGetG(abgr) (((abgr) >> 8) & 0xff)
#define TIFFGetB(abgr) (((abgr) >> 16) & 0xff)
#define TIFFGetA(abgr) (((abgr) >> 24) & 0xff)

int TIFFReadRGBAStrip(TIFF *tif, uint32 row, uint32 *raster)

DESCRIPTION

TIFFReadRGBAStrip reads a single strip of a strip-based image into memory, storing the result in the user supplied RGBA raster. The raster is assumed to be an array of width times rowsperstrip 32-bit entries, where width is the width of the image (TIFFTAG_IMAGEWIDTH) and rowsperstrip is the maximum lines in a strip (TIFFTAG_ROWSPERSTRIP).

The row value should be the row of the first row in the strip (strip * rowsperstrip, zero based).

Note that the raster is assume to be organized such that the pixel at location (x,y) is raster[y*width+x]; with the raster origin in the lower-left hand corner of the strip. That is bottom to top organization. When reading a partial last strip in the file the last line of the image will begin at the beginning of the buffer.

Raster pixels are 8-bit packed red, green, blue, alpha samples. The macros TIFFGetR, TIFFGetG, TIFFGetB, and TIFFGetA should be used to access individual samples. Images without Associated Alpha matting information have a constant Alpha of 1.0 (255).

See the TIFFRGBAImage(3TIFF) page for more details on how various image types are converted to RGBA values.

NOTES

Samples must be either 1, 2, 4, 8, or 16 bits. Colorimetric samples/pixel must be either 1, 3, or 4 (i.e. SamplesPerPixel minus ExtraSamples).

Palette image colormaps that appear to be incorrectly written as 8-bit values are automatically scaled to 16-bits.

TIFFReadRGBAStrip is just a wrapper around the more general TIFFRGBAImage(3TIFF) facilities. It’s main advantage over the similar TIFFReadRGBAImage() function is that for large images a single buffer capable of holding the whole image doesn’t need to be allocated, only enough for one strip. The TIFFReadRGBATile() function does a similar operation for tiled images.

RETURN VALUES

1 is returned if the image was successfully read and converted. Otherwise, 0 is returned if an error was encountered.

DIAGNOSTICS

All error messages are directed to the TIFFError(3TIFF) routine.

Sorry, can not handle %d-bit pictures. The image had BitsPerSample other than 1, 2, 4, 8, or 16.

Sorry, can not handle %d-channel images. The image had SamplesPerPixel other than 1, 3, or 4.

Missing needed "PhotometricInterpretation" tag. The image did not have a tag that describes how to display the data.

No "PhotometricInterpretation" tag, assuming RGB. The image was missing a tag that describes how to display it, but because it has 3 or 4 samples/pixel, it is assumed to be RGB.

No "PhotometricInterpretation" tag, assuming min-is-black. The image was missing a tag that describes how to display it, but because it has 1 sample/pixel, it is assumed to be a grayscale or bilevel image.

No space for photometric conversion table. There was insufficient memory for a table used to convert image samples to 8-bit RGB.

Missing required "Colormap" tag. A Palette image did not have a required Colormap tag.

No space for tile buffer. There was insufficient memory to allocate an i/o buffer.

No space for strip buffer. There was insufficient memory to allocate an i/o buffer.

Can not handle format. The image has a format (combination of BitsPerSample, SamplesPerPixel, and PhotometricInterpretation) that TIFFReadRGBAImage can not handle.

No space for B&W mapping table. There was insufficient memory to allocate a table used to map grayscale data to RGB.

No space for Palette mapping table. There was insufficient memory to allocate a table used to map data to 8-bit RGB.

TIFFReadScanline − read and decode a scanline of data from an open TIFF file

SYNOPSIS

#include <tiffio.h>

int TIFFReadScanline(TIFF *tif, tdata_t buf, uint32 row, tsample_t sample)

DESCRIPTION

Read the data for the specified row into the (user supplied) data buffer buf. The data are returned decompressed and, in the native byte- and bit-ordering, but are otherwise packed (see further below). The buffer must be large enough to hold an entire scanline of data. Applications should call the routine TIFFScanlineSize to find out the size (in bytes) of a scanline buffer. The row parameter is always used by TIFFReadScanline; the sample parameter is used only if data are organized in separate planes (PlanarConfiguration=2).

NOTES

The library attempts to hide bit- and byte-ordering differences between the image and the native machine by converting data to the native machine order. Bit reversal is done if the FillOrder tag is opposite to the native machine bit order. 16- and 32-bit samples are automatically byte-swapped if the file was written with a byte order opposite to the native machine byte order,

In C++ the sample parameter defaults to 0.

RETURN VALUES

TIFFReadScanline returns −1 if it detects an error; otherwise 1 is returned.

DIAGNOSTICS

All error messages are directed to the TIFFError(3TIFF) routine.

Compression algorithm does not support random access. Data was requested in a non-sequential order from a file that uses a compression algorithm and that has RowsPerStrip greater than one. That is, data in the image is stored in a compressed form, and with multiple rows packed into a strip. In this case, the library does not support random access to the data. The data should either be accessed sequentially, or the file should be converted so that each strip is made up of one row of data.

BUGS

Reading subsampled YCbCR data does not work correctly because, for PlanarConfiguration=2 the size of a scanline is not calculated on a per-sample basis, and for PlanarConfiguration=1 the library does not unpack the block-interleaved samples; use the strip- and tile-based interfaces to read these formats.

TIFFError, TIFFSetErrorHandler − library error handling interface

SYNOPSIS

#include <tiffio.h>

void TIFFError(const char *module, const char *fmt, ...)

#include <stdarg.h>

typedef void (*TIFFErrorHandler)(const char *module, const char *fmt, va_list ap);
TIFFErrorHandler TIFFSetErrorHandler(TIFFErrorHandler handler);

DESCRIPTION

TIFFError invokes the library-wide error handling function to (normally) write an error message to the stderr. The fmt parameter is a printf(3S) format string, and any number arguments can be supplied. The module parameter, if non-zero, is printed before the message; it typically is used to identify the software module in which an error is detected.

Applications that desire to capture control in the event of an error should use TIFFSetErrorHandler to override the default error handler. A NULL (0) error handling function may be installed to suppress error messages.

RETURN VALUES

TIFFSetErrorHandler returns a reference to the previous error handling function.

int TIFFReadRGBATile(TIFF *tif, uint32 x, uint32 y, uint32 *raster)

DESCRIPTION

TIFFReadRGBATile reads a single tile of a tile-based image into memory, storing the result in the user supplied RGBA raster. The raster is assumed to be an array of width times length 32-bit entries, where width is the width of a tile (TIFFTAG_TILEWIDTH) and length is the height of a tile (TIFFTAG_TILELENGTH).

The x and y values are the offsets from the top left corner to the top left corner of the tile to be read. They must be an exact multiple of the tile width and length.

Note that the raster is assume to be organized such that the pixel at location (x,y) is raster[y*width+x]; with the raster origin in the lower-left hand corner of the tile. That is bottom to top organization. Edge tiles which partly fall off the image will be filled out with appropriate zeroed areas.

Raster pixels are 8-bit packed red, green, blue, alpha samples. The macros TIFFGetR, TIFFGetG, TIFFGetB, and TIFFGetA should be used to access individual samples. Images without Associated Alpha matting information have a constant Alpha of 1.0 (255).

See the TIFFRGBAImage(3TIFF) page for more details on how various image types are converted to RGBA values.

NOTES

Samples must be either 1, 2, 4, 8, or 16 bits. Colorimetric samples/pixel must be either 1, 3, or 4 (i.e. SamplesPerPixel minus ExtraSamples).

Palette image colormaps that appear to be incorrectly written as 8-bit values are automatically scaled to 16-bits.

TIFFReadRGBATile is just a wrapper around the more general TIFFRGBAImage(3TIFF) facilities. It’s main advantage over the similar TIFFReadRGBAImage() function is that for large images a single buffer capable of holding the whole image doesn’t need to be allocated, only enough for one tile. The TIFFReadRGBAStrip() function does a similar operation for stripped images.

RETURN VALUES

1 is returned if the image was successfully read and converted. Otherwise, 0 is returned if an error was encountered.

DIAGNOSTICS

All error messages are directed to the TIFFError(3TIFF) routine.

Sorry, can not handle %d-bit pictures. The image had BitsPerSample other than 1, 2, 4, 8, or 16.

Sorry, can not handle %d-channel images. The image had SamplesPerPixel other than 1, 3, or 4.

TIFFGetBitRevTable, TIFFReverseBits, TIFFSwabShort, TIFFSwabLong, TIFFSwabArrayOfShort, TIFFSwabArrayOfLong − byte- and bit-swapping routines

SYNOPSIS

#include <tiffio.h>

const unsigned char* TIFFGetBitRevTable(int reversed)
void TIFFReverseBits(u_char *data, unsigned long nbytes)
void TIFFSwabShort(uint16 *data)
void TIFFSwabLong(uint32 *data)
void TIFFSwabArrayOfShort(uint16 *data, unsigned long nshorts)
void TIFFSwabArrayOfLong(uint32 *data, unsigned long nlongs)

DESCRIPTION

The following routines are used by the library to swap 16- and 32-bit data and to reverse the order of bits in bytes.

TIFFSwabShort and TIFFSwabLong swap the bytes in a single 16-bit and 32-bit item, respectively. TIFFSwabArrayOfShort and TIFFSwabArrayOfLong swap the bytes in an array of 16-bit and 32-bit items, respectively.

TIFFReverseBits replaces each byte in data with the equivalent bit-reversed value. This operation is performed with a lookup table, which is returned using the TIFFGetBitRevTable function. reversed parameter specifies which table should be returned. Supply 1 if you want bit reversal table. Supply 0 to get the table that do not reverse bit values. It is a lookup table that can be used as an identity function; i.e. TIFFNoBitRevTable[n] == n.

DIAGNOSTICS

None.

NAME

TIFFGetField, TIFFVGetField − get the value(s) of a tag in an open TIFF file

SYNOPSIS

#include <tiffio.h>

int TIFFGetField(TIFF *tif, ttag_t tag, ...)

#include <stdarg.h>

int TIFFVGetField(TIFF *tif, ttag_t tag, va_list ap)
int TIFFGetFieldDefaulted(TIFF *tif, ttag_t tag, ...)
int TIFFVGetFieldDefaulted(TIFF *tif, ttag_t tag, va_list ap)

DESCRIPTION

TIFFGetField returns the value of a tag or pseudo-tag associated with the the current directory of the opened TIFF file tif. (A pseudo-tag is a parameter that is used to control the operation of the TIFF library but whose value is not read or written to the underlying file.) The file must have been previously opened with TIFFOpen(3TIFF). The tag is identified by tag, one of the values defined in the include file tiff.h (see also the table below). The type and number of values returned is dependent on the tag being requested. The programming interface uses a variable argument list as prescribed by the stdarg(3) interface. The returned values should only be interpreted if TIFFGetField returns 1.

TIFFVGetField is functionally equivalent to TIFFGetField except that it takes a pointer to a variable argument list. TIFFVGetField is useful for layering interfaces on top of the functionality provided by TIFFGetField.

TIFFGetFieldDefaulted and TIFFVGetFieldDefaulted are identical to TIFFGetField and TIFFVGetField, except that if a tag is not defined in the current directory and it has a default value, then the default value is returned.

The tags understood by libtiff(3TIFF), the number of parameter values, and the types for the returned values are shown below. The data types are specified as in C and correspond to the types used to specify tag values to TIFFSetField(3TIFF). Remember that TIFFGetField returns parameter values, so all the listed data types are pointers to storage where values should be returned. Consult the TIFF specification (or relevant industry specification) for information on the meaning of each tag and their possible values.

AUTOREGISTERED TAGS

If you can’t find the tag in the table above that means this is unsupported tag. But you still be able to read it’s value if you know the data type of that tag. For example, if you want to read the LONG value from the tag 33424 and ASCII string from the tag 36867 you can use the following code:

uint16 count;
void *data;

TIFFGetField(tiff, 33424, &count, &data);
printf("Tag %d: %d, count %d0, 33424, *(uint32 *)data, count);
TIFFGetField(tiff, 36867, &count, &data);
printf("Tag %d: %s, count %d0, 36867, (char *)data, count);

is not supported by libtiff(3TIFF), library

RETURN VALUES

1 is returned if the tag is defined in the current directory; otherwise a 0 is returned.

DIAGNOSTICS

All error messages are directed to the TIFFError(3TIFF) routine.

Unknown field, tag 0x%x. An unknown tag was supplied.

SEE ALSO

NAME

tiffdump − print verbatim information about TIFF files

SYNOPSIS

tiffdump [ options ] name ...

DESCRIPTION

tiffdump displays directory information from files created according to the Tag Image File Format, Revision 6.0. The header of each TIFF file (magic number, version, and first directory offset) is displayed, followed by the tag contents of each directory in the file. For each tag, the name, data type, count, and value(s) is displayed. When the symbolic name for a tag or data type is known, the symbolic name is displayed followed by it’s numeric (decimal) value. Tag values are displayed enclosed in ‘‘<>’’ characters immediately preceded by the value of the count field. For example, an ImageWidth tag might be displayed as ‘‘ImageWidth (256) SHORT (3) 1<800>’’.

tiffdump is particularly useful for investigating the contents of TIFF files that libtiff does not understand.

OPTIONS

−h

Force numeric data to be printed in hexadecimal rather than the default decimal.

−m items

Change the number of indirect data items that are printed. By default, this will be 24.

−o offset

Dump the contents of the IFD at the a particular file offset. The file offset may be specified using the usual C-style syntax; i.e. a leading ‘‘0x’’ for hexadecimal and a leading ‘‘0’’ for octal.

NAME

tiffsv − save an image from the framebuffer in a TIFF file (Silicon Graphics version)

SYNOPSIS

tiffsv [ options ] output.tif [ x1 x2 y1 y2 ]

DESCRIPTION

tiffsv saves all or part of the framebuffer in a file using the Tag Image File Format, Revision 6.0. By default, the image is saved with data samples packed (PlanarConfiguration=1), compressed with the Lempel-Ziv & Welch algorithm (Compression=5), and with each strip no more than 8 kilobytes. These characteristics can be overridden, or explicitly specified with the options described below.

OPTIONS

−b

Save the image as a greyscale image as if it were processed by tiff2bw(1). This option is included for compatibility with the standard scrsave(6D) program.

−c

Specify the compression to use for data written to the output file: none for no compression, packbits for PackBits compression, jpeg for baseline JPEG compression, zip for Deflate compression, and lzw for Lempel-Ziv & Welch compression (default).

LZW compression can be specified together with a predictor value. A predictor value of 2 causes each scanline of the output image to undergo horizontal differencing before it is encoded; a value of 1 forces each scanline to be encoded without differencing. LZW-specific options are specified by appending a ‘‘:’’-separated list to the ‘‘lzw’’ option; e.g. −c lzw:2 for LZW compression with horizontal differencing.

−p

Specify the planar configuration to use in writing image data. By default, tiffsv will create a new file with the data samples packed contiguously. Specifying −p contig will force data to be written with multi-sample data packed together, while −p separate will force samples to be written in separate planes.

−r

Specify the number of rows (scanlines) in each strip of data written to the output file. By default, tiffsv attempts to set the rows/strip that no more than 8 kilobytes of data appear in a strip.

NOTE

Except for the use of TIFF, this program is equivalent to the standard scrsave program. This means, for example, that you can use it in conjunction with the standard icut program simply by creating a link called scrsave, or by creating a shell script called scrsave that invokes tiffgt with the appropriate options.

BUGS

If data are saved compressed and in separate planes, then the rows in each strip is silently set to one to avoid limitations in the libtiff(3TIFF) library.

DESCRIPTION

These routines are provided for writing portable software that uses libtiff; they hide any memory-management related issues, such as dealing with segmented architectures found on 16-bit machines.

_TIFFmalloc and _TIFFrealloc are used to dynamically allocate and reallocate memory used by libtiff; such as memory passed into the I/O routines. Memory allocated through these interfaces is released back to the system using the _TIFFfree routine.

Memory allocated through one of the above interfaces can be set to a known value using _TIFFmemset, copied to another memory location using _TIFFmemcpy, or compared for equality using _TIFFmemcmp. These routines conform to the equivalent ANSI C routines: memset, memcpy, and memcmp, repsectively.

DESCRIPTION

TIFFFieldReadCount returns the number of values available to be read from the specified TIFF field; that is, the number of arguments that should be supplied to TIFFGetField. For most field types this is a small positive integer, typically 1 or 2, but there are some special values:
TIFF_VARIABLE indicates that a variable number of values is possible; then, a uint16 count argument and a pointer data argument must be supplied to TIFFGetField.
TIFF_VARIABLE2 is the same as TIFF_VARIABLE except that the count argument must have type uint32.
TIFF_SPP indicates that the number of arguments is equal to the image’s number of samples per pixel.

fip is a field information pointer previously returned by TIFFFindField, TIFFFieldWithTag, or TIFFFieldWithName.

TIFFReadEncodedTile − read and decode a tile of data from an open TIFF file

SYNOPSIS

#include <tiffio.h>

int TIFFReadEncodedTile(TIFF *tif, ttile_t tile, tdata_t buf, tsize_t size)

DESCRIPTION

Read the specified tile of data and place up to size bytes of decompressed information in the (user supplied) data buffer.

NOTES

The value of tile is a ‘‘raw tile number.’’ That is, the caller must take into account whether or not the data are organized in separate planes (PlanarConfiguration=2). TIFFComputeTile automatically does this when converting an (x,y,z,sample) coordinate quadruple to a tile number. To read a full tile of data the data buffer should be at least as large as the value returned by TIFFTileSize.

The library attempts to hide bit- and byte-ordering differences between the image and the native machine by converting data to the native machine order. Bit reversal is done if the FillOrder tag is opposite to the native machine bit order. 16- and 32-bit samples are automatically byte-swapped if the file was written with a byte order opposite to the native machine byte order,

RETURN VALUES

The actual number of bytes of data that were placed in buf is returned; TIFFReadEncodedTile returns −1 if an error was encountered.

DIAGNOSTICS

All error messages are directed to the TIFFError(3TIFF) routine.

tiffgt displays one or more images stored using the Tag Image File Format, Revision 6.0. Each image is placed in a fixed size window that the user must position on the display (unless configured otherwise through X defaults). If the display has fewer than 24 bitplanes, or if the image does not warrant full color, then RGB color values are mapped to the closest values that exist in the colormap (this is done using the rgbi routine found in the graphics utility library −lgutil.)

tiffgt correctly handles files with any of the following characteristics:

BitsPerSample

1, 2, 4, 8, 16

SamplesPerPixel

1, 3, 4 (the 4th sample is ignored)

PhotometricInterpretation

0 (min-is-white), 1 (min-is-black), 2 (RGB), 3 (palette), 6 (YCbCr)

PlanarConfiguration

1 (contiguous), 2 (separate)

Orientation

1 (top-left), 4 (bottom-left)

Data may be organized as strips or tiles and may be compressed with any of the compression algorithms supported by the libtiff(3) library.

For palette images (PhotometricInterpretation=3), tiffgt inspects the colormap values and assumes either 16-bit or 8-bit values according to the maximum value. That is, if no colormap entry greater than 255 is found, tiffgt assumes the colormap has only 8-bit values; otherwise it assumes 16-bit values. This inspection is done to handle old images written by previous (incorrect) versions of libtiff.

tiffgt can be used to display multiple images one-at-a-time. The left mouse button switches the display to the first image in the next file in the list of files specified on the command line. The right mouse button switches to the first image in the previous file in the list. The middle mouse button causes the first image in the first file specified on the command line to be displayed. In addition the following keyboard commands are recognized:

b

Use a PhotometricInterpretation of MinIsBlack in displaying the current image.

l

Use a FillOrder of lsb-to-msb in decoding the current image.

m

Use a FillOrder of msb-to-lsb in decoding the current image.

c

Use a colormap visual to display the current image.

r

Use a true color (24-bit RGB) visual to display the current image.

w

Use a PhotometricInterpretation of MinIsWhite in displaying the current image.

W

Toggle (enable/disable) display of warning messages from the TIFF library when decoding images.

E

Toggle (enable/disable) display of error messages from the TIFF library when decoding images.

z

Reset all parameters to their default settings (FillOrder, PhotometricInterpretation, handling of warnings and errors).

PageUp

Display the previous image in the current file or the last image in the previous file.

PageDown

Display the next image in the current file or the first image in the next file.

Home

Display the first image in the current file.

End

Display the last image in the current file (unimplemented).

OPTIONS

−c

Force image display in a colormap window.

−d

Specify an image to display by directory number. By default the first image in the file is displayed. Directories are numbered starting at zero.

−e

Enable reporting of error messages from the TIFF library. By default tiffgt silently ignores images that cannot be read.

−f

Force tiffgt to run as a foreground process. By default tiffgt will place itself in the background once it has opened the requested image file.

−l

Force the presumed bit ordering to be LSB to MSB.

−m

Force the presumed bit ordering to be MSB to LSB.

−o

Specify an image to display by directory offset. By default the first image in the file is displayed. Directories offsets may be specified using C-style syntax; i.e. a leading ‘‘0x’’ for hexadecimal and a leading ‘‘0’’ for octal.

−p

Override the value of the PhotometricInterpretation tag; the parameter may be one of: miniswhite, minisblack, rgb, palette, mask, separated, ycbcr, and cielab.

−r

Force image display in a full color window.

−s

Stop on the first read error. By default all errors in the input data are ignored and tiffgt does it’s best to display as much of an image as possible.

−w

Enable reporting of warning messages from the TIFF library. By default tiffgt ignores warning messages generated when reading an image.

−v

Place information in the title bar describing what type of window (full color or colormap) is being used, the name of the input file, and the directory index of the image (if non-zero). By default, the window type is not shown in the title bar.

BUGS

Images wider and taller than the display are silently truncated to avoid crashing old versions of the window manager.

TIFFReadRGBAImage, TIFFReadRGBAImageOriented − read and decode an image into a fixed-format raster

SYNOPSIS

#include <tiffio.h>

#define TIFFGetR(abgr) ((abgr) & 0xff)
#define TIFFGetG(abgr) (((abgr) >> 8) & 0xff)
#define TIFFGetB(abgr) (((abgr) >> 16) & 0xff)
#define TIFFGetA(abgr) (((abgr) >> 24) & 0xff)

int TIFFReadRGBAImage(TIFF *tif, uint32 width, uint32 height, uint32 *raster, int stopOnError)
int TIFFReadRGBAImageOriented(TIFF *tif, uint32 width, uint32 height, uint32 *raster, int orientation, int stopOnError)

DESCRIPTION

TIFFReadRGBAImage reads a strip- or tile-based image into memory, storing the result in the user supplied raster. The raster is assumed to be an array of width times height 32-bit entries, where width must be less than or equal to the width of the image (height may be any non-zero size). If the raster dimensions are smaller than the image, the image data is cropped to the raster bounds. If the raster height is greater than that of the image, then the image data are placed in the lower part of the raster. (Note that the raster is assume to be organized such that the pixel at location (x,y) is raster[y*width+x]; with the raster origin in the lower-left hand corner.)

TIFFReadRGBAImageOriented works like TIFFReadRGBAImage with except of that user can specify the raster origin position with the orientation parameter. Four orientations supported:

ORIENTATION_TOPLEFT

origin in top-left corner,

ORIENTATION_TOPRIGHT

origin in top-right corner,

ORIENTATION_BOTLEFT

origin in bottom-left corner and

ORIENTATION_BOTRIGHT

origin in bottom-right corner.

If you choose ORIENTATION_BOTLEFT result will be the same as returned by the TIFFReadRGBAImage.

Raster pixels are 8-bit packed red, green, blue, alpha samples. The macros TIFFGetR, TIFFGetG, TIFFGetB, and TIFFGetA should be used to access individual samples. Images without Associated Alpha matting information have a constant Alpha of 1.0 (255).

TIFFReadRGBAImage converts non-8-bit images by scaling sample values. Palette, grayscale, bilevel, CMYK , and YCbCr images are converted to RGB transparently. Raster pixels are returned uncorrected by any colorimetry information present in the directory.

The paramater stopOnError specifies how to act if an error is encountered while reading the image. If stopOnError is non-zero, then an error will terminate the operation; otherwise TIFFReadRGBAImage will continue processing data until all the possible data in the image have been requested.

NOTES

In C++ the stopOnError parameter defaults to 0.

Samples must be either 1, 2, 4, 8, or 16 bits. Colorimetric samples/pixel must be either 1, 3, or 4 (i.e. SamplesPerPixel minus ExtraSamples).

Palettte image colormaps that appear to be incorrectly written as 8-bit values are automatically scaled to 16-bits.

TIFFReadRGBAImage is just a wrapper around the more general TIFFRGBAImage(3TIFF) facilities.

RETURN VALUES

1 is returned if the image was successfully read and converted. Otherwise, 0 is returned if an error was encountered and stopOnError is zero.

DIAGNOSTICS

All error messages are directed to the TIFFError(3TIFF) routine.

Sorry, can not handle %d-bit pictures. The image had BitsPerSample other than 1, 2, 4, 8, or 16.

Sorry, can not handle %d-channel images. The image had SamplesPerPixel other than 1, 3, or 4.

Missing needed "PhotometricInterpretation" tag. The image did not have a tag that describes how to display the data.

No "PhotometricInterpretation" tag, assuming RGB. The image was missing a tag that describes how to display it, but because it has 3 or 4 samples/pixel, it is assumed to be RGB.

No "PhotometricInterpretation" tag, assuming min-is-black. The image was missing a tag that describes how to display it, but because it has 1 sample/pixel, it is assumed to be a grayscale or bilevel image.

No space for photometric conversion table. There was insufficient memory for a table used to convert image samples to 8-bit RGB.

Missing required "Colormap" tag. A Palette image did not have a required Colormap tag.

No space for tile buffer. There was insufficient memory to allocate an i/o buffer.

No space for strip buffer. There was insufficient memory to allocate an i/o buffer.

Can not handle format. The image has a format (combination of BitsPerSample, SamplesPerPixel, and PhotometricInterpretation) that TIFFReadRGBAImage can not handle.

No space for B&W mapping table. There was insufficient memory to allocate a table used to map grayscale data to RGB.

No space for Palette mapping table. There was insufficient memory to allocate a table used to map data to 8-bit RGB.

tsize_t TIFFStripSize(TIFF *tif)
tsize_t TIFFVStripSize(TIFF *tif, uint32 nrows)
tsize_t TIFFRawStripSize(TIFF *tif, tstrip_t strip)
tstrip_t TIFFComputeStrip(TIFF *tif, uint32 row, tsample_t sample)
tstrip_t TIFFNumberOfStrips(TIFF *tif)

DESCRIPTION

TIFFDefaultStripSize returns the number of rows for a reasonable-sized strip according to the current settings of the ImageWidth, BitsPerSample, SamplesPerPixel, tags and any compression-specific requirements. If the estimate parameter, if non-zero, then it is taken as an estimate of the desired strip size and adjusted according to any compression-specific requirements. The value returned by this function is typically used to define the RowsPerStrip tag. In lieu of any unusual requirements TIFFDefaultStripSize tries to create strips that have approximately 8 kilobytes of uncompressed data.

TIFFStripSize returns the equivalent size for a strip of data as it would be returned in a call to TIFFReadEncodedStrip or as it would be expected in a call to TIFFWriteEncodedStrip.

TIFFVStripSize returns the number of bytes in a strip with nrows rows of data.

TIFFRawStripSize returns the number of bytes in a raw strip (i.e. not decoded).

TIFFComputeStrip returns the strip that contains the specified coordinates. A valid strip is always returned; out-of-range coordinate values are clamped to the bounds of the image. The row parameter is always used in calculating a strip. The sample parameter is used only if data are organized in separate planes (PlanarConfiguration=2).

TIFFNumberOfStrips returns the number of strips in the image.

DIAGNOSTICS

None.

ras2tiff − create a TIFF file from a Sun rasterfile

SYNOPSIS

ras2tiff [ options ] input.ras output.tif

DESCRIPTION

ras2tiff converts a file in the Sun rasterfile format to TIFF. By default, the TIFF image is created with data samples packed (PlanarConfiguration=1), compressed with the Lempel-Ziv & Welch algorithm (Compression=5), and with each strip no more than 8 kilobytes. These characteristics can overridden, or explicitly specified with the options described below.

Any colormap information in the rasterfile is carried over to the TIFF file by including a Colormap tag in the output file. If the rasterfile has a colormap, the PhotometricInterpretation tag is set to 3 (palette); otherwise it is set to 2 (RGB) if the depth is 24 or 1 (min-is-black) if the depth is not 24.

OPTIONS

−c

Specify a compression scheme to use when writing image data: −c none for no compression, −c packbits for the PackBits compression algorithm, −c jpeg for the baseline JPEG compression algorithm, −c zip for the Deflate compression algorithm, and −c lzw for Lempel-Ziv & Welch (the default).

−r

Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approximately 8 kilobytes.

BUGS

Does not handle all possible rasterfiles. In particular, ras2tiff does not handle run-length encoded images.

fax2tiff − create a TIFF Class F fax file from raw fax data

SYNOPSIS

fax2tiff [ options ] [ −o output.tif ] input.raw

DESCRIPTION

Fax2tiff creates a TIFF file containing CCITT Group 3 or Group 4 encoded data from one or more files containing ‘‘raw’’ Group 3 or Group 4 encoded data (typically obtained directly from a fax modem). By default, each row of data in the resultant TIFF file is 1-dimensionally encoded and padded or truncated to 1728 pixels, as needed. The resultant image is a set of low resolution (98 lines/inch) or medium resolution (196 lines/inch) pages, each of which is a single strip of data. The generated file conforms to the TIFF Class F ( FAX ) specification for storing facsimile data. This means, in particular, that each page of the data does not include the trailing return to control ( RTC ) code; as required for transmission by the CCITT Group 3 specifications. The old, ‘‘classic’’, format is created if the −c option is used. (The Class F format can also be requested with the −f option.)

The default name of the output image is fax.tif; this can be changed with the −o option. Each input file is assumed to be a separate page of facsimile data from the same document. The order in which input files are specified on the command line is the order in which the resultant pages appear in the output file.

OPTIONS

Options that affect the interpretation of input data are:

−3

Assume input data is CCITT Group 3 encoded (default).

−4

Assume input data is CCITT Group 4 encoded.

−U

Assume input data is uncompressed (Group 3 or Group 4).

−1

Assume input data is encoded with the 1-dimensional version of the CCITT Group 3 Huffman encoding algorithm (default).

−2

Assume input data is 2-dimensional version of the CCITT Group 3 Huffman encoding algorithm.

−P

Assume input data is not EOL-aligned (default). This option has effect with Group 3 encoded input only.

−A

Assume input data is EOL-aligned. This option has effect with Group 3 encoded input only.

−M

Treat input data as having bits filled from most significant bit ( MSB ) to most least bit ( LSB ).

−L

Treat input data as having bits filled from least significant bit ( LSB ) to most significant bit ( MSB ) (default).

−B

Assume input data was encoded with black as 0 and white as 1.

−W

Assume input data was encoded with black as 1 and white as 0 (default).

−R

Specify the vertical resolution, in lines/inch, of the input images. By default input are assumed to have a vertical resolution of 196 lines/inch. If images are low resolution facsimile, a value of 98 lines/inch should be specified.

−X

Specify the width, in pixels, of the input images. By default input are assumed to have a width of 1728 pixels.

Options that affect the output file format are:

−o

Specify the name of the output file.

−7

Force output to be compressed with the CCITT Group 3 Huffman encoding algorithm (default).

−8

Force output to be compressed with the CCITT Group 4 Huffman encoding.

−u

Force output to be uncompressed (Group 3 or Group 4).

−5

Force output to be encoded with the 1-dimensional version of the CCITT Group 3 Huffman encoding algorithm.

−6

Force output to be encoded with the 2-dimensional version of the CCITT Group 3 Huffman encoding algorithm (default).

−a

Force the last bit of each End Of Line ( EOL ) code to land on a byte boundary (default). This ‘‘zero padding’’ will be reflected in the contents of the Group3Options tag of the resultant TIFF file. This option has effect with Group 3 encoded output only.

−p

Do not EOL-align output. This option has effect with Group 3 encoded output only.

−c

Generate "classic" Group 3 TIFF format.

−f

Generate TIFF Class F (TIFF/F) format (default).

−m

Force output data to have bits filled from most significant bit ( MSB ) to most least bit ( LSB ).

−l

Force output data to have bits filled from least significant bit ( LSB ) to most significant bit ( MSB ) (default).

−r

Specify the number of rows (scanlines) in each strip of data written to the output file. By default (or when value 0 is specified), tiffcp attempts to set the rows/strip that no more than 8 kilobytes of data appear in a strip (with except of G3/G4 compression schemes). If you specify special value −1 it will results in infinite number of the rows per strip. The entire image will be the one strip in that case. This is default in case of G3/G4 output compression schemes.

−s

Stretch the input image vertically by writing each input row of data twice to the output file.

−v

Force fax2tiff to print the number of rows of data it retrieved from the input file.

−z

Force output to be compressed with the LZW encoding.

DIAGNOSTICS

The following warnings and errors come from the decoding routines in the library.

Warning, %s: Premature EOL at scanline %d (x %d).\n. The input data had a row that was shorter than the expected width. The row is padded with white.

%s: Premature EOF at scanline %d (x %d).\n. The decoder ran out of data in the middle of a scanline. The resultant row is padded with white.

%s: Bad code word at row %d, x %d\n. An invalid Group 3 code was encountered while decoding the input file. The row number and horizontal position is given. The remainder of the input row is discarded, while the corresponding output row is padded with white.

%s: Bad 2D code word at scanline %d.\n. An invalid Group 4 or 2D Group 3 code was encountered while decoding the input file. The row number and horizontal position is given. The remainder of the input row is discarded, while the corresponding output row is padded with white.

BUGS

Input data are assumed to have a a ‘‘top left’’ orientation; it should be possible to override this assumption from the command line.

rgb2ycbcr − convert non-YCbCr TIFF images to a YCbCr TIFF image

SYNOPSIS

DESCRIPTION

rgb2ycbcr converts RGB color, greyscale, or bi-level TIFF images to YCbCr images by transforming and sampling pixel data. If multiple files are specified on the command line each source file is converted to a separate directory in the destination file.

By default, chrominance samples are created by sampling 2 by 2 blocks of luminance values; this can be changed with the −h and −v options. Output data are compressed with the PackBits compression scheme, by default; an alternate scheme can be selected with the −c option. By default, output data are compressed in strips with the number of rows in each strip selected so that the size of a strip is never more than 8 kilobytes; the −r option can be used to explicitly set the number of rows per strip.

OPTIONS

−c

Specify a compression scheme to use when writing image data: −c none for no compression, −c packbits for the PackBits compression algorithm (the default), −c jpeg for the JPEG compression algorithm, −c zip for the deflate compression algorithm, and −c lzw for Lempel-Ziv & Welch.

−h

Set the horizontal sampling dimension to one of: 1, 2 (default), or 4.

−r

Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approximately 8 kilobytes.

−v

Set the vertical sampling dimension to one of: 1, 2 (default), or 4.

TIFFCodec* TIFFRegisterCODEC(uint16 scheme, const char *method, TIFFInitMethod init);
void TIFFUnRegisterCODEC(TIFFCodec *codec);

DESCRIPTION

libtiff supports a variety of compression schemes implemented by software codecs. Each codec adheres to a modular interface that provides for the decoding and encoding of image data; as well as some other methods for initialization, setup, cleanup, and the control of default strip and tile sizes. Codecs are identified by the associated value of the TIFF Compression tag; e.g. 5 for LZW compression.

The TIFFRegisterCODEC routine can be used to augment or override the set of codecs available to an application. If the specified scheme already has a registered codec then it is overridden and any images with data encoded with this compression scheme will be decoded using the supplied coded.

TIFFIsCODECConfigured returns 1 if the codec is configured and working. Otherwise 0 will be returned.

DIAGNOSTICS

No space to register compression scheme %s. TIFFRegisterCODEC was unable to allocate memory for the data structures needed to register a codec.

Cannot remove compression scheme %s; not registered. TIFFUnRegisterCODEC did not locate the specified codec in the table of registered compression schemes.

TIFFReadDirectory − get the contents of the next directory in an open TIFF file

SYNOPSIS

#include <tiffio.h>

int TIFFReadDirectory(TIFF *tif)

DESCRIPTION

Read the next directory in the specified file and make it the current directory. Applications only need to call TIFFReadDirectory to read multiple subfiles in a single TIFF file— the first directory in a file is automatically read when TIFFOpen is called.

NOTES

If the library is compiled with STRIPCHOP_SUPPORT enabled, then images that have a single uncompressed strip or tile of data are automatically treated as if they were made up of multiple strips or tiles of approximately 8 kilobytes each. This operation is done only in-memory; it does not alter the contents of the file. However, the construction of the ‘‘chopped strips’’ is visible to the application through the number of strips [tiles] returned by TIFFNumberOfStrips [TIFFNumberOfTiles].

RETURN VALUES

If the next directory was successfully read, 1 is returned. Otherwise, 0 is returned if an error was encountered, or if there are no more directories to be read.

DIAGNOSTICS

All error messages are directed to the TIFFError(3TIFF) routine. All warning messages are directed to the TIFFWarning(3TIFF) routine.

Seek error accessing TIFF directory. An error occurred while positioning to the location of the directory.

Wrong data type %d for field "%s". The tag entry in the directory had an incorrect data type. For example, an ImageDescription tag with a SHORT data type.

TIFF directory is missing required "%s" field. The specified tag is required to be present by the TIFF 5.0 specification, but is missing. The directory is (usually) unusable.

%s: Rational with zero denominator. A directory tag has a RATIONAL value whose denominator is zero.

Incorrect count %d for field "%s" (%lu, expecting %lu); tag ignored. The specified tag’s count field is bad. For example, a count other than 1 for a SubFileType tag.

Cannot handle different per-sample values for field "%s". The tag has SamplesPerPixel values and they are not all the same; e.g. BitsPerSample. The library is unable to handle images of this sort.

Count mismatch for field "%s"; expecting %d, got %d. The count field in a tag does not agree with the number expected by the library. This should never happen, so if it does, the library refuses to read the directory.

Invalid TIFF directory; tags are not sorted in ascending order. The directory tags are not properly sorted as specified in the TIFF 5.0 specification. This error is not fatal.

Ignoring unknown field with tag %d (0x%x). An unknown tag was encountered in the directory; the library ignores all such tags.

TIFF directory is missing requred "ImageLength" field. The image violates the specification by not having a necessary field. There is no way for the library to recover from this error.

TIFF directory is missing requred "PlanarConfig" field. The image violates the specification by not having a necessary field. There is no way for the library to recover from this error.

TIFF directory is missing requred "StripOffsets" field. The image has multiple strips, but is missing the tag that specifies the file offset to each strip of data. There is no way for the library to recover from this error.

TIFF directory is missing requred "TileOffsets" field. The image has multiple tiles, but is missing the tag that specifies the file offset to each tile of data. There is no way for the library to recover from this error.

TIFF directory is missing required "StripByteCounts" field. The image has multiple strips, but is missing the tag that specifies the size of each strip of data. There is no way for the library to recover from this error.

TIFF directory is missing required "StripByteCounts" field, calculating from imagelength. The image violates the specification by not having a necessary field. However, when the image is comprised of only one strip or tile, the library will estimate the missing value based on the file size.

Bogus "StripByteCounts" field, ignoring and calculating from imagelength. Certain vendors violate the specification by writing zero for the StripByteCounts tag when they want to leave the value unspecified. If the image has a single strip, the library will estimate the missing value based on the file size.

tiff2pdf − convert a TIFF image to a PDF document

SYNOPSIS

tiff2pdf [ options ] input.tiff

DESCRIPTION

tiff2pdf opens a TIFF image and writes a PDF document to standard output.

The program converts one TIFF file to one PDF file, including multiple page TIFF files, tiled TIFF files, black and white. grayscale, and color TIFF files that contain data of TIFF photometric interpretations of bilevel, grayscale, RGB, YCbCr, CMYK separation, and ICC L*a*b* as supported by libtiff and PDF.

If you have multiple TIFF files to convert into one PDF file then use tiffcp or other program to concatenate the files into a multiple page TIFF file. If the input TIFF file is of huge dimensions (greater than 10000 pixels height or width) convert the input image to a tiled TIFF if it is not already.

The standard output is standard output. Set the output file name with the −o output.pdf option.

All black and white files are compressed into a single strip CCITT G4 Fax compressed PDF, unless tiled, where tiled black and white images are compressed into tiled CCITT G4 Fax compressed PDF, libtiff CCITT support is assumed.

Color and grayscale data can be compressed using either JPEG compression, ITU-T T.81, or Zip/Deflate LZ77 compression. Set the compression type using the −j or −z options. JPEG compression support requires that libtiff be configured with JPEG support, and Zip/Deflate compression support requires that libtiff be configured with Zip support, in tiffconf.h. Use only one or the other of −j and −z.

If the input TIFF contains single strip CCITT G4 Fax compressed information, then that is written to the PDF file without transcoding, unless the options of no compression and no passthrough are set, −d and −n.

If the input TIFF contains JPEG or single strip Zip/Deflate compressed information, and they are configured, then that is written to the PDF file without transcoding, unless the options of no compression and no passthrough are set.

The default page size upon which the TIFF image is placed is determined by the resolution and extent of the image data. Default values for the TIFF image resolution can be set using the −x and −y options. The page size can be set using the −p option for paper size, or −w and −l for paper width and length, then each page of the TIFF image is centered on its page. The distance unit for default resolution and page width and length can be set by the −u option, the default unit is inch.

Various items of the output document information can be set with the −e, −c, −a, −t, −s, and −k options. Setting the argument of the option to "" for these tags causes the relevant document information field to be not written. Some of the document information values otherwise get their information from the input TIFF image, the software, author, document name, and image description.

TIFFReadEncodedStrip − read and decode a strip of data from an open TIFF file

SYNOPSIS

#include <tiffio.h>

tsize_t TIFFReadEncodedStrip(TIFF *tif, tstrip_t strip, tdata_t buf, tsize_t size)

DESCRIPTION

Read the specified strip of data and place up to size bytes of decompressed information in the (user supplied) data buffer.

NOTES

The value of strip is a ‘‘raw strip number.’’ That is, the caller must take into account whether or not the data are organized in separate planes (PlanarConfiguration=2). To read a full strip of data the data buffer should typically be at least as large as the number returned by TIFFStripSize(3TIFF). If the -1 passed in size parameter, the whole strip will be read. You should be sure you have enough space allocated for the buffer.

The library attempts to hide bit- and byte-ordering differences between the image and the native machine by converting data to the native machine order. Bit reversal is done if the FillOrder tag is opposite to the native machine bit order. 16- and 32-bit samples are automatically byte-swapped if the file was written with a byte order opposite to the native machine byte order,

RETURN VALUES

The actual number of bytes of data that were placed in buf is returned; TIFFReadEncodedStrip returns −1 if an error was encountered.

DIAGNOSTICS

All error messages are directed to the TIFFError(3TIFF) routine.

DESCRIPTION

TIFFSetDirectory changes the current directory and reads its contents with TIFFReadDirectory. The parameter dirnum specifies the subfile/directory as an integer number, with the first directory numbered zero.

TIFFSetSubDirectory acts like TIFFSetDirectory, except the directory is specified as a file offset instead of an index; this is required for accessing subdirectories linked through a SubIFD tag.

RETURN VALUES

On successful return 1 is returned. Otherwise, 0 is returned if dirnum or diroff specifies a non-existent directory, or if an error was encountered while reading the directory’s contents.

DIAGNOSTICS

All error messages are directed to the TIFFError(3TIFF) routine.

%s: Error fetching directory count. An error was encountered while reading the ‘‘directory count’’ field.

%s: Error fetching directory link. An error was encountered while reading the ‘‘link value’’ that points to the next directory in a file.

tiffdither − convert a greyscale image to bilevel using dithering

SYNOPSIS

tiffdither [ options ] input.tif output.tif

DESCRIPTION

tiffdither converts a single channel 8-bit greyscale image to a bilevel image using Floyd-Steinberg error propagation with thresholding.

OPTIONS

−c

Specify the compression to use for data written to the output file: none for no compression, packbits for PackBits compression, lzw for Lempel-Ziv & Welch compression, zip for Deflate compression, g3 for CCITT Group 3 (T.4) compression, and g4 for CCITT Group 4 (T.6) compression. By default tiffdither will compress data according to the value of the Compression tag found in the source file.

The CCITT Group 3 and Group 4 compression algorithms can only be used with bilevel data.

Group 3 compression can be specified together with several T.4-specific options: 1d for 1-dimensional encoding, 2d for 2-dimensional encoding, and fill to force each encoded scanline to be zero-filled so that the terminating EOL code lies on a byte boundary. Group 3-specific options are specified by appending a ‘‘:’’-separated list to the ‘‘g3’’ option; e.g. −c g3:2d:fill to get 2D-encoded data with byte-aligned EOL codes.

LZW compression can be specified together with a predictor value. A predictor value of 2 causes each scanline of the output image to undergo horizontal differencing before it is encoded; a value of 1 forces each scanline to be encoded without differencing. LZW-specific options are specified by appending a ‘‘:’’-separated list to the ‘‘lzw’’ option; e.g. −c lzw:2 for LZW compression with horizontal differencing.

−f

Specify the bit fill order to use in writing output data. By default, tiffdither will create a new file with the same fill order as the original. Specifying −f lsb2msb will force data to be written with the FillOrder tag set to LSB2MSB , while −f msb2lsb will force data to be written with the Fill- Order tag set to MSB2LSB .

−t

Set the threshold value for dithering. By default the threshold value is 128.

NOTES

The dither algorithm is taken from the tiffmedian(1) program (written by Paul Heckbert).

DESCRIPTION

tiffsplit takes a multi-directory (page) TIFF file and creates one or more single-directory (page) TIFF files from it. The output files are given names created by concatenating a prefix, a lexically ordered suffix in the range [aaa-zzz], the suffix .tif (e.g. xaaa.tif, xaab.tif, xzzz.tif). If a prefix is not specified on the command line, the default prefix of x is used.

OPTIONS

None.

NAME

raw2tiff − create a TIFF file from a raw data

SYNOPSIS

raw2tiff [ options ] input.raw output.tif

DESCRIPTION

raw2tiff converts a raw byte sequence into TIFF. By default, the TIFF image is created with data samples packed (PlanarConfiguration=1), compressed with the PackBits algorithm (Compression=32773), and with each strip no more than 8 kilobytes. These characteristics can overridden, or explicitly specified with the options described below.

OPTIONS

−H number

size of input image file header in bytes (0 by default). This amount of data just will be skipped from the start of file while reading.

−w number

width of input image in pixels (can be guessed, see GUESSING THE IMAGE GEOMETRY below).

−l number

length of input image in lines (can be guessed, see GUESSING THE IMAGE GEOMETRY below).

−b number

number of bands in input image (1 by default).

−d data_type

type of samples in input image, where data_type may be:

byte

8-bit unsigned integer (default),

short

16-bit unsigned integer,

long

32-bit unsigned integer,

sbyte

8-bit signed integer,

sshort

16-bit signed integer,

slong

32-bit signed integer,

float

32-bit IEEE floating point,

double

64-bit IEEE floating point.

−i config

type of samples interleaving in input image, where config may be:

pixel

pixel interleaved data (default),

band

band interleaved data.

−p photo

photometric interpretation (color space) of the input image, where photo may be:

miniswhite

white color represented with 0 value,

minisblack

black color represented with 0 value (default),

rgb

image has RGB color model,

cmyk

image has CMYK (separated) color model,

ycbcr

image has YCbCr color model,

cielab

image has CIE L*a*b color model,

icclab

image has ICC L*a*b color model,

itulab

image has ITU L*a*b color model.

−s

swap bytes fetched from the input file.

−L

input data has LSB2MSB bit order (default).

−M

input data has MSB2LSB bit order.

−c

Specify a compression scheme to use when writing image data: −c none for no compression, −c packbits for the PackBits compression algorithm (the default), −c jpeg for the baseline JPEG compression algorithm, −c zip for the Deflate compression algorithm, and −c lzw for Lempel-Ziv & Welch.

−r number

Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approximately 8 kilobytes.

GUESSING THE IMAGE GEOMETRY

raw2tiff can guess image width and height in case one or both of these parameters are not specified. If you omit one of those parameters, the complementary one will be calculated based on the file size (taking into account header size, number of bands and data type). If you omit both parameters, the statistical approach will be used. Utility will compute correlation coefficient between two lines at the image center using several appropriate line sizes and the highest absolute value of the coefficient will indicate the right line size. That is why you should be cautious with the very large images, because guessing process may take a while (depending on your system performance). Of course, the utility can’t guess the header size, number of bands and data type, so it should be specified manually. If you don’t know anything about your image, just try with the several combinations of those options.

There is no magic, it is just a mathematical statistics, so it can be wrong in some cases. But for most ordinary images guessing method will work fine.

thumbnail − create a TIFF file with thumbnail images

SYNOPSIS

thumbnail [ options ] input.tif output.tif

DESCRIPTION

thumbnail is a program written to show how one might use the SubIFD tag (#330) to store thumbnail images. thumbnail copies a TIFF Class F facsimile file to the output file and for each image an 8-bit greyscale thumbnail sketch. The output file contains the thumbnail image with the associated full-resolution page linked below with the SubIFD tag.

By default, thumbnail images are 216 pixels wide by 274 pixels high. Pixels are calculated by sampling and filtering the input image with each pixel value passed through a contrast curve.

OPTIONS

−w

Specify the width of thumbnail images in pixels.

−h

Specify the height of thumbnail images in pixels.

−c

Specify a contrast curve to apply in generating the thumbnail images. By default pixels values are passed through a linear contrast curve that simply maps the pixel value ranges. Alternative curves are: exp50 for a 50% exponential curve, exp60 for a 60% exponential curve, exp70 for a 70% exponential curve, exp80 for a 80% exponential curve, exp90 for a 90% exponential curve, exp for a pure exponential curve, linear for a linear curve.

BUGS

There are no options to control the format of the saved thumbnail images.

NAME

tiffcp − copy (and possibly convert) a TIFF file

SYNOPSIS

tiffcp [ options ] src1.tif ... srcN.tif dst.tif

DESCRIPTION

tiffcp combines one or more files created according to the Tag Image File Format, Revision 6.0 into a single TIFF file. Because the output file may be compressed using a different algorithm than the input files, tiffcp is most often used to convert between different compression schemes.

By default, tiffcp will copy all the understood tags in a TIFF directory of an input file to the associated directory in the output file.

tiffcp can be used to reorganize the storage characteristics of data in a file, but it is explicitly intended to not alter or convert the image data content in any way.

OPTIONS

−b image

subtract the following monochrome image from all others processed. This can be used to remove a noise bias from a set of images. This bias image is typically an image of noise the camera saw with its shutter closed.

−B

Force output to be written with Big-Endian byte order. This option only has an effect when the output file is created or overwritten and not when it is appended to.

−C

Suppress the use of ‘‘strip chopping’’ when reading images that have a single strip/tile of uncompressed data.

−c

Specify the compression to use for data written to the output file: none for no compression, packbits for PackBits compression, lzw for Lempel-Ziv & Welch compression, jpeg for baseline JPEG compression, zip for Deflate compression, g3 for CCITT Group 3 (T.4) compression, and g4 for CCITT Group 4 (T.6) compression. By default tiffcp will compress data according to the value of the Compression tag found in the source file.

The CCITT Group 3 and Group 4 compression algorithms can only be used with bilevel data.

Group 3 compression can be specified together with several T.4-specific options: 1d for 1-dimensional encoding, 2d for 2-dimensional encoding, and fill to force each encoded scanline to be zero-filled so that the terminating EOL code lies on a byte boundary. Group 3-specific options are specified by appending a ‘‘:’’-separated list to the ‘‘g3’’ option; e.g. −c g3:2d:fill to get 2D-encoded data with byte-aligned EOL codes.

LZW compression can be specified together with a predictor value. A predictor value of 2 causes each scanline of the output image to undergo horizontal differencing before it is encoded; a value of 1 forces each scanline to be encoded without differencing. LZW-specific options are specified by appending a ‘‘:’’-separated list to the ‘‘lzw’’ option; e.g. −c lzw:2 for LZW compression with horizontal differencing.

−f

Specify the bit fill order to use in writing output data. By default, tiffcp will create a new file with the same fill order as the original. Specifying −f lsb2msb will force data to be written with the FillOrder tag set to LSB2MSB, while −f msb2lsb will force data to be written with the FillOrder tag set to MSB2LSB.

−i

Ignore non-fatal read errors and continue processing of the input file.

−l

Specify the length of a tile (in pixels). tiffcp attempts to set the tile dimensions so that no more than 8 kilobytes of data appear in a tile.

−L

Force output to be written with Little-Endian byte order. This option only has an effect when the output file is created or overwritten and not when it is appended to.

−M

Suppress the use of memory-mapped files when reading images.

−p

Specify the planar configuration to use in writing image data that has one 8-bit sample per pixel. By default, tiffcp will create a new file with the same planar configuration as the original. Specifying −p contig will force data to be written with multi-sample data packed together, while −p separate will force samples to be written in separate planes.

−r

Specify the number of rows (scanlines) in each strip of data written to the output file. By default (or when value 0 is specified), tiffcp attempts to set the rows/strip that no more than 8 kilobytes of data appear in a strip. If you specify special value −1 it will results in infinite number of the rows per strip. The entire image will be the one strip in that case.

−s

Force the output file to be written with data organized in strips (rather than tiles).

−t

Force the output file to be written with data organized in tiles (rather than strips). options can be used to force the resultant image to be written as strips or tiles of data, respectively.

−w

Specify the width of a tile (in pixels). tiffcp attempts to set the tile dimensions so that no more than 8 kilobytes of data appear in a tile. tiffcp attempts to set the tile dimensions so that no more than 8 kilobytes of data appear in a tile.

−x

Force the output file to be written with PAGENUMBER value in sequence.

−,=character

substitute character for ‘,’ in parsing image directory indices in files. This is necessary if filenames contain commas. Note that −,= with whitespace immediately following will disable the special meaning of the ‘,’ entirely. See examples.

EXAMPLES

The following concatenates two files and writes the result using LZW encoding:

 
tiffcp −c lzw a.tif b.tif result.tif

To convert a G3 1d-encoded TIFF to a single strip of G4-encoded data the following might be used:

 
tiffcp −c g4 −r 10000 g3.tif g4.tif

(1000 is just a number that is larger than the number of rows in the source file.)

To extract a selected set of images from a multi-image TIFF file, the file name may be immediately followed by a ‘,’ separated list of image directory indices. The first image is always in directory 0. Thus, to copy the 1st and 3rd images of image file ‘‘album.tif’’ to ‘‘result.tif’’:

 
tiffcp album.tif,0,2 result.tif

A trailing comma denotes remaining images in sequence. The following command will copy all image with except the first one:

 
tiffcp album.tif,1, result.tif

Given file ‘‘CCD.tif’’ whose first image is a noise bias followed by images which include that bias, subtract the noise from all those images following it (while decompressing) with the command:

 
tiffcp −c none −b CCD.tif CCD.tif,1, result.tif

If the file above were named ‘‘CCD,X.tif’’, the −,= option would be required to correctly parse this filename with image numbers, as follows:

 
tiffcp −c none −,=% −b CCD,X.tif CCD,X%1%.tif result.tif

NAME

tiff2rgba − convert a TIFF image to RGBA color space

SYNOPSIS

tiff2rgba [ options ] input.tif output.tif

DESCRIPTION

Tiff2rgba converts a wide variety of TIFF images into an RGBA TIFF image. This includes the ability to translate different color spaces and photometric interpretation into RGBA, support for alpha blending, and translation of many different bit depths into a 32bit RGBA image.

Internally this program is implemented using the TIFFReadRGBAImage() function, and it suffers any limitations of that image. This includes limited support for > 8 BitsPerSample images, and flaws with some esoteric combinations of BitsPerSample, photometric interpretation, block organization and planar configuration.

The generated images are stripped images with four samples per pixel (red, green, blue and alpha) or if the −n flag is used, three samples per pixel (red, green, and blue). The resulting images are always planar configuration contiguous. For this reason, this program is a useful utility for transform exotic TIFF files into a form ingestible by almost any TIFF supporting software.

OPTIONS

−c

Specify a compression scheme to use when writing image data: −c none for no compression (the default), −c packbits for the PackBits compression algorithm, −c zip for the Deflate compression algorithm, −c jpeg for the JPEG compression algorithm, and −c lzw for Lempel-Ziv & Welch.

−r

Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approximately 8 kilobytes.

−b

Process the image one block (strip/tile) at a time instead of by reading the whole image into memory at once. This may be necessary for very large images on systems with limited RAM.

−n

Drop the alpha component from the output file, producing a pure RGB file. Currently this does not work if the −b flag is also in effect.

DESCRIPTION

Write the data for the tile containing the specified coordinates. The data in buf are is (potentially) compressed, and written to the indicated file, normally being appended to the end of the file. The buffer must be contain an entire tile of data. Applications should call the routine TIFFTileSize to find out the size (in bytes) of a tile buffer. The x and y parameters are always used by TIFFWriteTile. The z parameter is used if the image is deeper than 1 slice (ImageDepth>1). The sample parameter is used only if data are organized in separate planes (PlanarConfiguration=2).

RETURN VALUES

TIFFWriteTile returns −1 if it detects an error; otherwise the number of bytes in the tile is returned.

DIAGNOSTICS

All error messages are directed to the TIFFError(3TIFF) routine.

TIFFFieldPassCount − Get whether to pass a count to TIFFGet/SetField

SYNOPSIS

#include <tiffio.h>

int TIFFFieldPassCount(const TIFFField* fip)

DESCRIPTION

TIFFFieldPassCount returns true (nonzero) if TIFFGetField and TIFFSetField expect a count value to be passed before the actual data pointer.

fip is a field information pointer previously returned by TIFFFindField, TIFFFieldWithTag, or TIFFFieldWithName.

When a count is required, it will be of type uint32 when TIFFFieldReadCount reports TIFF_VARIABLE2, and of type uint16 otherwise. (This distinction is critical for use of TIFFGetField, but normally not so for use of TIFFSetField.)

RETURN VALUES

TIFFFieldPassCount returns an integer that is always 1 (true) or 0 (false).

    TIFFReadTile − read and decode a tile of data from an open TIFF file

    SYNOPSIS

    #include <tiffio.h>

    tsize_t TIFFReadTile(TIFF *tif, tdata_t buf, uint32 x, uint32 y, uint32 z, tsample_t sample)

    DESCRIPTION

    Return the data for the tile containing the specified coordinates. The data placed in buf are returned decompressed and, typically, in the native byte- and bit-ordering, but are otherwise packed (see further below). The buffer must be large enough to hold an entire tile of data. Applications should call the routine TIFFTileSize to find out the size (in bytes) of a tile buffer. The x and y parameters are always used by TIFFReadTile. The z parameter is used if the image is deeper than 1 slice (ImageDepth>1). The sample parameter is used only if data are organized in separate planes (PlanarConfiguration=2).

    NOTES

    The library attempts to hide bit- and byte-ordering differences between the image and the native machine by converting data to the native machine order. Bit reversal is done if the FillOrder tag is opposite to the native machine bit order. 16- and 32-bit samples are automatically byte-swapped if the file was written with a byte order opposite to the native machine byte order,

    RETURN VALUES

    TIFFReadTile returns −1 if it detects an error; otherwise the number of bytes in the decoded tile is returned.

    DIAGNOSTICS

    All error messages are directed to the TIFFError(3TIFF) routine.

    SYNOPSIS

    #include <tiffio.h>

    int TIFFWriteDirectory(TIFF *tif)
    int TIFFRewriteDirectory(TIFF *    tif)
    int TIFFCheckpointDirectory(TIFF *    tif)

    DESCRIPTION

    TIFFWriteDirectory will write the contents of the current directory to the file and setup to create a new subfile in the same file. Applications only need to call TIFFWriteDirectory when writing multiple subfiles to a single TIFF file. TIFFWriteDirectory is automatically called by TIFFClose and TIFFFlush to write a modified directory if the file is open for writing.

    The TIFFRewriteDirectory function operates similarly to TIFFWriteDirectory, but can be called with directories previously read or written that already have an established location in the file. It will rewrite the directory, but instead of place it at it’s old location (as TIFFWriteDirectory would) it will place them at the end of the file, correcting the pointer from the preceeding directory or file header to point to it’s new location. This is particularly important in cases where the size of the directory and pointed to data has grown, so it won’t fit in the space available at the old location.

    The TIFFCheckpointDirectory writes the current state of the tiff directory into the file to make what is currently in the file readable. Unlike TIFFWriteDirectory, TIFFCheckpointDirectory does not free up the directory data structures in memory, so they can be updated (as strips/tiles are written) and written again. Reading such a partial file you will at worst get a tiff read error for the first strip/tile encountered that is incomplete, but you will at least get all the valid data in the file before that. When the file is complete, just use TIFFWriteDirectory as usual to finish it off cleanly.

    RETURN VALUES

    1 is returned when the contents are successfully written to the file. Otherwise, 0 is returned if an error was encountered when writing the directory contents.

    DIAGNOSTICS

    All error messages are directed to the TIFFError(3TIFF) routine.

    Error post-encoding before directory write. Before writing the contents of the current directory, any pending data are flushed. This message indicates that an error occurred while doing this.

    Error flushing data before directory write. Before writing the contents of the current directory, any pending data are flushed. This message indicates that an error occurred while doing this.

    Cannot write directory, out of space. There was not enough space to allocate a temporary area for the directory that was to be written.

    Error writing directory count. A write error occurred when writing the count of fields in the directory.

    Error writing directory contents. A write error occurred when writing the directory fields.

    Error writing directory link. A write error occurred when writing the link to the next directory.

    Error writing data for field "%s". A write error occurred when writing indirect data for the specified field.

    Error writing TIFF header. A write error occurred when re-writing header at the front of the file.

    Error fetching directory count. A read error occurred when fetching the directory count field for a previous directory. This can occur when setting up a link to the directory that is being written.

    Error fetching directory link. A read error occurred when fetching the directory link field for a previous directory. This can occur when setting up a link to the directory that is being written.

    NAME

    ppm2tiff − create a TIFF file from PPM, PGM and PBM image files

    SYNOPSIS

    ppm2tiff [ options ] [ input.ppm ] output.tif

    DESCRIPTION

    ppm2tiff converts a file in the PPM, PGM and PBM image formats to TIFF. By default, the TIFF image is created with data samples packed (PlanarConfiguration=1), compressed with the Packbits algorithm (Compression=32773), and with each strip no more than 8 kilobytes. These characteristics can be overridden, or explicitly specified with the options described below

    If the PPM file contains greyscale data, then the PhotometricInterpretation tag is set to 1 (min-is-black), otherwise it is set to 2 (RGB).

    If no PPM file is specified on the command line, ppm2tiff will read from the standard input.

    OPTIONS

    −c

    Specify a compression scheme to use when writing image data: none for no compression, packbits for PackBits compression (will be used by default), lzw for Lempel-Ziv & Welch compression, jpeg for baseline JPEG compression, zip for Deflate compression, g3 for CCITT Group 3 (T.4) compression, and g4 for CCITT Group 4 (T.6) compression.

    −r

    Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approximately 8 kilobytes.

    −R

    Mark the resultant image to have the specified X and Y resolution (in dots/inch).

    TIFFSetField, TIFFVSetField − set the value(s) of a tag in a TIFF file open for writing

    SYNOPSIS

    #include <tiffio.h>

    int TIFFSetField(TIFF *tif, ttag_t tag, ...)

    #include <stdarg.h>

    int TIFFVSetField(TIFF *tif, ttag_t tag, va_list ap)

    DESCRIPTION

    TIFFSetField sets the value of a field or pseudo-tag in the current directory associated with the open TIFF file tif. (A pseudo-tag is a parameter that is used to control the operation of the TIFF library but whose value is not read or written to the underlying file.) To set the value of a field the file must have been previously opened for writing with TIFFOpen(3TIFF); pseudo-tags can be set whether the file was opened for reading or writing. The field is identified by tag, one of the values defined in the include file tiff.h (see also the table below). The actual value is specified using a variable argument list, as prescribed by the stdarg(3) interface (or, on some machines, the varargs(3) interface.)

    TIFFVSetField is functionally equivalent to TIFFSetField except that it takes a pointer to a variable argument list. TIFFVSetField is useful for writing routines that are layered on top of the functionality provided by TIFFSetField.

    The tags understood by libtiff, the number of parameter values, and the expected types for the parameter values are shown below. The data types are: char* is null-terminated string and corresponds to the ASCII data type; uint16 is an unsigned 16-bit value; uint32 is an unsigned 32-bit value; uint16* is an array of unsigned 16-bit values. void* is an array of data values of unspecified type.

    Consult the TIFF specification for information on the meaning of each tag.

    DESCRIPTION

    TIFFOpen opens a TIFF file whose name is filename and returns a handle to be used in subsequent calls to routines in libtiff. If the open operation fails, then zero is returned. The mode parameter specifies if the file is to be opened for reading (‘‘r’’), writing (‘‘w’’), or appending (‘‘a’’) and, optionally, whether to override certain default aspects of library operation (see below). When a file is opened for appending, existing data will not be touched; instead new data will be written as additional subfiles. If an existing file is opened for writing, all previous data is overwritten.

    If a file is opened for reading, the first TIFF directory in the file is automatically read (also see TIFFSetDirectory(3TIFF) for reading directories other than the first). If a file is opened for writing or appending, a default directory is automatically created for writing subsequent data. This directory has all the default values specified in TIFF Revision 6.0: BitsPerSample=1, ThreshHolding=bilevel art scan, FillOrder=1 (most significant bit of each data byte is filled first), Orientation=1 (the 0th row represents the visual top of the image, and the 0th column represents the visual left hand side), SamplesPerPixel=1, RowsPerStrip=infinity, ResolutionUnit=2 (inches), and Compression=1 (no compression). To alter these values, or to define values for additional fields, TIFFSetField(3TIFF) must be used.

    TIFFFdOpen is like TIFFOpen except that it opens a TIFF file given an open file descriptor fd. The file’s name and mode must reflect that of the open descriptor. The object associated with the file descriptor must support random access.

    TIFFClientOpen is like TIFFOpen except that the caller supplies a collection of functions that the library will use to do UNIX -like I/O operations. The readproc and writeproc are called to read and write data at the current file position. seekproc is called to change the current file position a la lseek(2). closeproc is invoked to release any resources associated with an open file. sizeproc is invoked to obtain the size in bytes of a file. mapproc and unmapproc are called to map and unmap a file’s contents in memory; c.f. mmap(2) and munmap(2). The clientdata parameter is an opaque ‘‘handle’’ passed to the client-specified routines passed as parameters to TIFFClientOpen.

    OPTIONS

    The open mode parameter can include the following flags in addition to the ‘‘r’’, ‘‘w’’, and ‘‘a’’ flags. Note however that option flags must follow the read-write-append specification.

    l

    When creating a new file force information be written with Little-Endian byte order (but see below). By default the library will create new files using the native CPU byte order.

    b

    When creating a new file force information be written with Big-Endian byte order (but see below). By default the library will create new files using the native CPU byte order.

    L

    Force image data that is read or written to be treated with bits filled from Least Significant Bit ( LSB ) to Most Significant Bit ( MSB ). Note that this is the opposite to the way the library has worked from its inception.

    B

    Force image data that is read or written to be treated with bits filled from Most Significant Bit ( MSB ) to Least Significant Bit ( LSB ); this is the default.

    H

    Force image data that is read or written to be treated with bits filled in the same order as the native CPU.

    M

    Enable the use of memory-mapped files for images opened read-only. If the underlying system does not support memory-mapped files or if the specific image being opened cannot be memory-mapped then the library will fallback to using the normal system interface for reading information. By default the library will attempt to use memory-mapped files.

    m

    Disable the use of memory-mapped files.

    C

    Enable the use of ‘‘strip chopping’’ when reading images that are comprised of a single strip or tile of uncompressed data. Strip chopping is a mechanism by which the library will automatically convert the single-strip image to multiple strips, each of which has about 8 Kilobytes of data. This facility can be useful in reducing the amount of memory used to read an image because the library normally reads each strip in its entirety. Strip chopping does however alter the apparent contents of the image because when an image is divided into multiple strips it looks as though the underlying file contains multiple separate strips. Finally, note that default handling of strip chopping is a compile-time configuration parameter. The default behaviour, for backwards compatibility, is to enable strip chopping.

    c

    Disable the use of strip chopping when reading images.

    h

    Read TIFF header only, do not load the first image directory. That could be useful in case of the broken first directory. We can open the file and proceed to the other directories.

    BYTE ORDER

    The TIFF specification (all versions) states that compliant readers must be capable of reading images written in either byte order. Nonetheless some software that claims to support the reading of TIFF images is incapable of reading images in anything but the native CPU byte order on which the software was written. (Especially notorious are applications written to run on Intel-based machines.) By default the library will create new files with the native byte-order of the CPU on which the application is run. This ensures optimal performance and is portable to any application that conforms to the TIFF specification. To force the library to use a specific byte-order when creating a new file the ‘‘b’’ and ‘‘l’’ option flags may be included in the call to open a file; for example, ‘‘wb’’ or ‘‘wl’’.

    RETURN VALUES

    Upon successful completion TIFFOpen, TIFFFdOpen, and TIFFClientOpen return a TIFF pointer. Otherwise, NULL is returned.

    DIAGNOSTICS

    All error messages are directed to the TIFFError(3TIFF) routine. Likewise, warning messages are directed to the TIFFWarning(3TIFF) routine.

    "%s": Bad mode. The specified mode parameter was not one of ‘‘r’’ (read), ‘‘w’’ (write), or ‘‘a’’ (append).

    %s: Cannot open. TIFFOpen() was unable to open the specified filename for read/writing.

    Cannot read TIFF header. An error occurred while attempting to read the header information.

    Error writing TIFF header. An error occurred while writing the default header information for a new file.

    Not a TIFF file, bad magic number %d (0x%x). The magic number in the header was not (hex) 0x4d4d or (hex) 0x4949.

    Not a TIFF file, bad version number %d (0x%x). The version field in the header was not 42 (decimal).

    Cannot append to file that has opposite byte ordering. A file with a byte ordering opposite to the native byte ordering of the current machine was opened for appending (‘‘a’’). This is a limitation of the library.

    pal2rgb − convert a palette color TIFF image to a full color image

    SYNOPSIS

    pal2rgb [ options ] input.tif output.tif

    DESCRIPTION

    Pal2rgb converts a palette color TIFF image to a full color image by applying the colormap of the palette image to each sample to generate a full color RGB image.

    OPTIONS

    Options that affect the interpretation of input data are:

    −C

    This option overrides the default behavior of pal2rgb in determining whether or not colormap entries contain 16-bit or 8-bit values. By default the colormap is inspected and if no colormap entry greater than 255 is found, the colormap is assumed to have only 8-bit values; otherwise 16-bit values (as required by the TIFF specification) are assumed. The −C option can be used to explicitly specify the number of bits for colormap entries: −C 8 for 8-bit values, −C 16 for 16-bit values.

    Options that affect the output file format are:

    −p

    Explicitly select the planar configuration used in organizing data samples in the output image: −p contig for samples packed contiguously, and −p separate for samples stored separately. By default samples are packed.

    −c

    Use the specific compression algorithm to encoded image data in the output file: −c packbits for Macintosh Packbits, −c lzw for Lempel-Ziv & Welch, −c zip for Deflate, −c none for no compression. If no compression-related option is specified, the input file’s compression algorithm is used.

    −r

    Explicitly specify the number of rows in each strip of the output file. If the −r option is not specified, a number is selected such that each output strip has approximately 8 kilobytes of data in it.

    BUGS

    Only 8-bit images are handled.

    NAME

    tiff2ps − convert a TIFF image to PostScript™

    SYNOPSIS

    tiff2ps [ options ] input.tif ...

    DESCRIPTION

    tiff2ps reads TIFF images and writes PostScript or Encapsulated PostScript (EPS) on the standard output. By default, tiff2ps writes Encapsulated PostScript for the first image in the specified TIFF image file.

    By default, tiff2ps will generate PostScript that fills a printed area specified by the TIFF tags in the input file. If the file does not contain XResolution or YResolution tags, then the printed area is set according to the image dimensions. The −w and −h options (see below) can be used to set the dimensions of the printed area in inches; overriding any relevant TIFF tags.

    The PostScript generated for RGB, palette, and CMYK images uses the colorimage operator. The PostScript generated for greyscale and bilevel images uses the image operator. When the colorimage operator is used, PostScript code to emulate this operator on older PostScript printers is also generated. Note that this emulation code can be very slow.

    Color images with associated alpha data are composited over a white background.

    OPTIONS

    −1

    Generate PostScript Level 1 (the default).

    −2

    Generate PostScript Level 2.

    −3

    Generate PostScript Level 3. It basically allows one to use the /flateDecode filter for ZIP compressed TIFF images.

    −a

    Generate output for all IFDs (pages) in the input file.

    −b

    Specify the bottom margin for the output (in inches). This does not affect the height of the printed image.

    −c

    Center the image in the output. This option only shows an effect if both the −w and the −h option are given.

    −d

    Set the initial TIFF directory to the specified directory number. (NB: Directories are numbered starting at zero.) This option is useful for selecting individual pages in a multi-page (e.g. facsimile) file.

    −e

    Force the generation of Encapsulated PostScript (implies −z).

    −h

    Specify the vertical size of the printed area (in inches).

    −H

    Specify the maximum height of image (in inches). Images with larger sizes will be split in several pages. Option −L may be used for specifying size of split images overlapping.

    −i

    Enable/disable pixel interpolation. This option requires a single numeric value: zero to disable pixel interpolation and non-zero to enable. The default is enabled.

    −L

    Specify the size of overlapping for split images (in inches). Used in conjunction with −H option.

    −l

    Specify the left margin for the output (in inches). This does not affect the width of the printed image.

    −m

    Where possible render using the imagemask PostScript operator instead of the image operator. When this option is specified tiff2ps will use imagemask for rendering 1 bit deep images. If this option is not specified or if the image depth is greater than 1 then the image operator is used.

    −o

    Set the initial TIFF directory to the IFD at the specified file offset. This option is useful for selecting thumbnail images and the like which are hidden using the SubIFD tag.

    −p

    Force the generation of (non-Encapsulated) PostScript.

    −r

    Rotate image by 180 degrees.

    −s

    Generate output for a single IFD (page) in the input file.

    −w

    Specify the horizontal size of the printed area (in inches).

    −x

    Override resolution units specified in the TIFF as centimeters.

    −y

    Override resolution units specified in the TIFF as inches.

    −z

    When generating PostScript Level 2, data is scaled so that it does not image into the deadzone on a page (the outer margin that the printing device is unable to mark). This option suppresses this behavior. When PostScript Level 1 is generated, data is imaged to the entire printed page and this option has no affect.

    EXAMPLES

    The following generates PostScript Level 2 for all pages of a facsimile:

    		 
    tiff2ps −a2 fax.tif | lpr

    Note also that if you have version 2.6.1 or newer of Ghostscript then you can efficiently preview facsimile generated with the above command.

    To generate Encapsulated PostScript for a the image at directory 2 of an image use:

    		 
    tiff2ps −d 1 foo.tif

    (Notice that directories are numbered starting at zero.)

    If you have a long image, it may be split in several pages:

    		 
    tiff2ps −h11 −w8.5 −H14 −L.5 foo.tif > foo.ps

    The page size is set to 8.5x11 by −w and −h options. We will accept a small amount of vertical compression, so −H set to 14. Any pages between 11 and 14 inches will be fit onto one page. Pages longer than 14 inches are cut off at 11 and continued on the next page. The −L.5 option says to repeat a half inch on the next page (to improve readability).

    BUGS

    Because PostScript does not support the notion of a colormap, 8-bit palette images produce 24-bit PostScript images. This conversion results in output that is six times bigger than the original image and which takes a long time to send to a printer over a serial line. Matters are even worse for 4-, 2-, and 1-bit palette images.

    Does not handle tiled images when generating PostScript Level I output.

    Gif2tiff converts a file in the GIF87 format to TIFF. The TIFF image is created as a palette image, with samples compressed with the Lempel-Ziv & Welch algorithm (Compression=5). These characteristics can overridden, or explicitly specified with the options described below.

    OPTIONS

    −c

    Specify a compression scheme to use when writing image data: −c none for no compression, −c packbits for the PackBits compression algorithm, −c zip for the Deflate compression algorithm, and −c lzw for Lempel-Ziv & Welch (the default).

    −r

    Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approximately 8 kilobytes.

    NOTES

    The program is based on Paul Haeberli’s fromgif program which, in turn, is based on Marcel J.E. Mol’s GIF reader.

    SYNOPSIS

    DESCRIPTION

    TIFFFieldWriteCount returns the number of values to be written into the specified TIFF field; that is, the number of arguments that should be supplied to TIFFSetField. For most field types this is a small positive integer, typically 1 or 2, but there are some special values:
    TIFF_VARIABLE     indicates that a variable number of values is possible; then, a uint16 count argument and a pointer data argument must be supplied to TIFFSetField.
    TIFF_VARIABLE2     is the same as TIFF_VARIABLE except that the count argument must have type uint32. (On most modern machines, this makes no practical difference, and the count argument can simply be an int in either case.)
    TIFF_SPP     indicates that the number of arguments must be equal to the image’s number of samples per pixel.

    fip is a field information pointer previously returned by TIFFFindField, TIFFFieldWithTag, or TIFFFieldWithName.

    For most field types, TIFFFieldWriteCount returns the same value as TIFFFieldReadCount, but there are some exceptions.

    RETURN VALUES

    TIFFFieldWriteCount returns an integer.

    DESCRIPTION

    The following routines return status information about an open TIFF file.

    TIFFCurrentDirectory returns the index of the current directory (directories are numbered starting at 0). This number is suitable for use with the TIFFSetDirectory routine.

    TIFFLastDirectory returns a non-zero value if the current directory is the last directory in the file; otherwise zero is returned.

    TIFFCurrentRow, TIFFCurrentStrip, and TIFFCurrentTile, return the current row, strip, and tile, respectively, that is being read or written. These values are updated each time a read or write is done.

    TIFFFileno returns the underlying file descriptor used to access the TIFF image in the filesystem.

    TIFFFileName returns the pathname argument passed to TIFFOpen or TIFFFdOpen.

    TIFFGetMode returns the mode with which the underlying file was opened. On UNIX systems, this is the value passed to the open(2) system call.

    TIFFIsTiled returns a non-zero value if the image data has a tiled organization. Zero is returned if the image data is organized in strips.

    TIFFIsByteSwapped returns a non-zero value if the image data was in a different byte-order than the host machine. Zero is returned if the TIFF file and local host byte-orders are the same. Note that TIFFReadTile(), TIFFReadStrip() and TIFFReadScanline() functions already normally perform byte swapping to local host order if needed.

    TIFFIsUpSampled returns a non-zero value if image data returned through the read interface routines is being up-sampled. This can be useful to applications that want to calculate I/O buffer sizes to reflect this usage (though the usual strip and tile size routines already do this).

    TIFFIsMSB2LSB returns a non-zero value if the image data is being returned with bit 0 as the most significant bit.

    TIFFGetVersion returns an ASCII string that has a version stamp for the TIFF library software.

    DIAGNOSTICS

    None.

    TIFFWriteScanline − write a scanline to an open TIFF file

    SYNOPSIS

    #include <tiffio.h>

    int TIFFWriteScanline(TIFF *tif, tdata_t buf, uint32 row, tsample_t sample)

    DESCRIPTION

    Write data to a file at the specified row. The sample parameter is used only if data are organized in separate planes (PlanarConfiguration=2). The data are assumed to be uncompressed and in the native bit- and byte-order of the host machine. The data written to the file is compressed according to the compression scheme of the current TIFF directory (see further below). If the current scanline is past the end of the current subfile, the ImageLength field is automatically increased to include the scanline (except for PlanarConfiguration=2, where the ImageLength cannot be changed once the first data are written). If the ImageLength is increased, the StripOffsets and StripByteCounts fields are similarly enlarged to reflect data written past the previous end of image.

    NOTES

    The library writes encoded data using the native machine byte order. Correctly implemented TIFF readers are expected to do any necessary byte-swapping to correctly process image data with BitsPerSample greater than 8. The library attempts to hide bit-ordering differences between the image and the native machine by converting data from the native machine order.

    In C++ the sample parameter defaults to 0.

    Once data are written to a file for the current directory, the values of certain tags may not be altered; see TIFFSetField(3TIFF) for more information.

    It is not possible to write scanlines to a file that uses a tiled organization. The routine TIFFIsTiled can be used to determine if the file is organized as tiles or strips.

    RETURN VALUES

    TIFFWriteScanline returns −1 if it immediately detects an error and 1 for a successful write.

    DIAGNOSTICS

    All error messages are directed to the TIFFError(3TIFF) routine.

    %s: File not open for writing . The file was opened for reading, not writing.

    Can not write scanlines to a tiled image. An attempt was made to write a scanline to a tiled image. The image is assumed to be organized in tiles because the TileWidth and TileLength tags have been set with TIFFSetField(3TIFF).

    Compression algorithm does not support random access. Data was written in a non-sequential order to a file that uses a compression algorithm and that has RowsPerStrip greater than one. That is, data in the image is to be stored in a compressed form, and with multiple rows packed into a strip. In this case, the library does not support random access to the data. The data should either be written as entire strips, sequentially by rows, or the value of RowsPerStrip should be set to one.

    %s: Must set "ImageWidth" before writing data. The image’s width has not be set before the first write. See TIFFSetField(3TIFF) for information on how to do this.

    %s: Must set "PlanarConfiguration" before writing data. The organization of data has not be defined before the first write. See TIFFSetField(3TIFF) for information on how to do this.

    Can not change "ImageLength" when using separate planes. Separate image planes are being used (PlanarConfiguration=2), but the number of rows has not been specified before the first write. The library supports the dynamic growth of an image only when data are organized in a contiguous manner (PlanarConfiguration=1).

    %d: Sample out of range, max %d. The sample parameter was greater than the value of the SamplesPerPixel tag.

    %s: No space for strip arrays . There was not enough space for the arrays that hold strip offsets and byte counts.

    BUGS

    Writing subsampled YCbCR data does not work correctly because, for PlanarConfiguration=2 the size of a scanline is not calculated on a per-sample basis, and for PlanarConfiguration=1 the library does not pack the block-interleaved samples.

    DESCRIPTION

    sgi2tiff converts a file in the SGI image format to TIFF. By default, the TIFF image is created with data samples packed (PlanarConfiguration=1), compressed with the Lempel-Ziv & Welch algorithm (Compression=5), and with each strip no more than 8 kilobytes. These characteristics can overridden, or explicitly specified with the options described below.

    OPTIONS

    −c

    Specify a compression scheme to use when writing image data: −c none for no compression, −c packbits for the PackBits compression algorithm), −c jpeg for the baseline JPEG compression algorithm, −c zip for the Deflate compression algorithm, and −c lzw for Lempel-Ziv & Welch (the default).

    −p

    Explicitly select the planar configuration used in organizing data samples in the output image: −p contig for samples packed contiguously, and −p separate for samples stored separately. By default samples are packed.

    −r

    Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approximately 8 kilobytes.

    BUGS

    Does not record colormap information.

    NAME

    libtiff − introduction to libtiff, a library for reading and writing TIFF files

    SYNOPSIS

    #include <tiffio.h>

    cc file.c -ltiff

    DESCRIPTION

    libtiff is a library for reading and writing data files encoded with the Tag Image File format, Revision 6.0 (or revision 5.0 or revision 4.0). This file format is suitable for archiving multi-color and monochromatic image data.

    The library supports several compression algorithms, as indicated by the Compression field, including: no compression (1), CCITT 1D Huffman compression (2), CCITT Group 3 Facsimile compression (3), CCITT Group 4 Facsimile compression (4), Lempel-Ziv & Welch compression (5), baseline JPEG compression (7), word-aligned 1D Huffman compression (32771), and PackBits compression (32773). In addition, several nonstandard compression algorithms are supported: the 4-bit compression algorithm used by the ThunderScan program (32809) (decompression only), NeXT’s 2-bit compression algorithm (32766) (decompression only), an experimental LZ-style algorithm known as Deflate (32946), and an experimental CIE LogLuv compression scheme designed for images with high dynamic range (32845 for LogL and 32845 for LogLuv). Directory information may be in either little- or big-endian byte order−byte swapping is automatically done by the library. Data bit ordering may be either Most Significant Bit ( MSB ) to Least Significant Bit ( LSB ) or LSB to MSB. Finally, the library does not support files in which the BitsPerSample, Compression, MinSampleValue, or MaxSampleValue fields are defined differently on a per-sample basis (in Rev. 6.0 the Compression tag is not defined on a per-sample basis, so this is immaterial).

    DATA TYPES

    The library makes extensive use of C typedefs to promote portability. Two sets of typedefs are used, one for communication with clients of the library and one for internal data structures and parsing of the TIFF format. The following typedefs are exposed to users either through function definitions or through parameters passed through the varargs interfaces.

    typedef unsigned short uint16;

    16-bit unsigned integer

    typedef unsigned <thing> uint32;

    32-bit unsigned integer

    typedef unsigned int ttag_t;

    directory tag

    typedef uint16 tdir_t;

    directory index

    typedef uint16 tsample_t;

    sample number

    typedef uint32 tstrip_t;

    strip number

    typedef uint32 ttile_t;

    tile number

    typedef int32 tsize_t;

    i/o size in bytes

    typedef void* tdata_t;

    image data ref

    typedef void* thandle_t;

    client data handle

    typedef int32 toff_t;

    file offset

    Note that tstrip_t, ttile_t, and tsize_t are constrained to be no more than 32-bit quantities by 32-bit fields they are stored in in the TIFF image. Likewise tsample_t is limited by the 16-bit field used to store the SamplesPerPixel tag. tdir_t constrains the maximum number of IFDs that may appear in an image and may be an arbitrary size (w/o penalty). ttag_t must be either int, unsigned int, pointer, or double because the library uses a varargs interface and ANSI C restricts the type of the parameter before an ellipsis to be a promoted type. toff_t is defined as int32 because TIFF file offsets are (unsigned) 32-bit quantities. A signed value is used because some interfaces return −1 on error. Finally, note that user-specified data references are passed as opaque handles and only cast at the lowest layers where their type is presumed.

    NAME

    tiffmedian − apply the median cut algorithm to data in a TIFF file

    SYNOPSIS

    tiffmedian [ options ] input.tif output.tif

    DESCRIPTION

    tiffmedian applies the median cut algorithm to an RGB image in input.tif to generate a palette image that is written to output.tif. The generated colormap has, by default, 256 entries. The image data is quantized by mapping each pixel to the closest color values in the colormap.

    OPTIONS

    −c

    Specify the compression to use for data written to the output file: none for no compression, packbits for PackBits compression, lzw for Lempel-Ziv & Welch compression, and zip for Deflate compression. By default tiffmedian will compress data according to the value of the Compression tag found in the source file.

    LZW compression can be specified together with a predictor value. A predictor value of 2 causes each scanline of the output image to undergo horizontal differencing before it is encoded; a value of 1 forces each scanline to be encoded without differencing. LZW-specific options are specified by appending a ‘‘:’’-separated list to the ‘‘lzw’’ option; e.g. −c lzw:2 for LZW compression with horizontal differencing.

    −C

    Specify the number of entries to use in the generated colormap. By default all 256 entries/colors are used.

    −f

    Apply Floyd-Steinberg dithering before selecting a colormap entry.

    −r

    Specify the number of rows (scanlines) in each strip of data written to the output file. By default, tiffmedian attempts to set the rows/strip that no more than 8 kilobytes of data appear in a strip.

    NOTES

    This program is derived from Paul Heckbert’s median program.

    NAME

    tiffcrop − copy (and possibly convert and crop or process) a TIFF file

    SYNOPSIS

    tiffcrop [ options ] src1.tif ... srcN.tif dst.tif

    DESCRIPTION

    tiffcrop combines one or more files created according to the Tag Image File Format, Revision 6.0 into a single TIFF file. The output file may be compressed using a different algorithm than the input files. tiffcrop is most often used to extract portions of an image for processing with bar code recognizer or OCR software when that software cannot restrict the region of interest to a specific portion of the image or to improve efficiency when the regions of interest must be rotated.

    By default, tiffcrop will copy all the understood tags in a TIFF directory of an input file to the associated directory in the output file.

    tiffcrop can be used to reorganize the storage characteristics of data in a file, and it will alter or convert the image data content as specified at the same time, unlike tiffcp.

    tiffcrop will behave exactly like tiffcp if none of the new options are specified.

    OPTIONS

    −N odd|even|#,#-#,#|last

    sequences and ranges of images within file to process. The words odd or even may be used to specify all odd or even numbered images. The word last may be used in place of a number in the sequence to indicate the final image in the file without knowing how many images there are. Ranges of images may be specified with a dash and multiple sets can be indicated by joining them in a comma-separated list. e.g.. use −N 1,5-7,last to process the 1st, 5th through 7th, and final image in the file.

    −E top|bottom|left|right

    use the top, bottom, left, or right edge as origin reference for width and length of crop regions. May be abbreviated to first letter.

    −U in|cm|px

    units to apply to dimensions for margins and crop regions. Inches or centimeters are converted to pixels using the resolution unit specified in the TIFF file (which defaults to inches if not specified in the IFD).

    −m #,#,#,#

    margins to be removed from the image. The order must be top, left, bottom, right with only commas separating the elements of the list. Margins are scaled according to the current units and removed before any other extractions are computed. Capital M was in use.

    −X #

    horizontal (X-axis) dimension of a region to extract relative to the specified origin reference. If the origin is the top or bottom edge, the X axis value will be assumed to start at the left edge.

    −Y #

    vertical (Y-axis) dimension of a region to extract relative to the specified origin reference. If the origin is the left or right edge, the Y axis value will be assumed to start at the top.

    −Z #:#,#:#

    zones of the image designated as position X of Y equal sized portions measured from the reference edge, e.g. 1:3 would be first third of the image starting from the reference edge minus any margins specified for the confining edges. Multiple zones can be specified as a comma separated list but they must reference the same edge. To extract the top quarter and the bottom third of an image you would use −Z 1:4,3:3.

    −F horiz|vert

    flip, i.e. mirror, the image or extracted region horizontally or vertically.

    −R 90|180|270

    rotate the image or extracted region 90, 180, or 270 degrees clockwise.

    −I

    invert the colorspace values for grayscale and bi-level images. This would be used to correct negative images that have incorrect PHOTOMETRIC INTERPRETATION tags. No support for color images.

    −b image

    subtract the following monochrome image from all others processed. This can be used to remove a noise bias from a set of images. This bias image is typically an image of noise the camera saw with its shutter closed. Bias image support is not available with options for cropping, rotating, or inverting the image.

    −B

    Force output to be written with Big-Endian byte order. This option only has an effect when the output file is created or overwritten and not when it is appended to.

    −C

    Suppress the use of ‘‘strip chopping’’ when reading images that have a single strip/tile of uncompressed data.

    −c

    Specify the compression to use for data written to the output file: none for no compression, packbits for PackBits compression, lzw for Lempel-Ziv & Welch compression, jpeg for baseline JPEG compression, zip for Deflate compression, g3 for CCITT Group 3 (T.4) compression, and g4 for CCITT Group 4 (T.6) compression. By default tiffcrop will compress data according to the value of the Compression tag found in the source file.

    The CCITT Group 3 and Group 4 compression algorithms can only be used with bi-level data.

    Group 3 compression can be specified together with several T.4-specific options: 1d for 1-dimensional encoding, 2d for 2-dimensional encoding, and fill to force each encoded scanline to be zero-filled so that the terminating EOL code lies on a byte boundary. Group 3-specific options are specified by appending a ‘‘:’’-separated list to the ‘‘g3’’ option; e.g. −c g3:2d:fill to get 2D-encoded data with byte-aligned EOL codes.

    LZW compression can be specified together with a predictor value. A predictor value of 2 causes each scanline of the output image to undergo horizontal differencing before it is encoded; a value of 1 forces each scanline to be encoded without differencing. LZW-specific options are specified by appending a ‘‘:’’-separated list to the ‘‘lzw’’ option; e.g. −c lzw:2 for LZW compression with horizontal differencing.

    −f

    Specify the bit fill order to use in writing output data. By default, tiffcrop will create a new file with the same fill order as the original. Specifying −f lsb2msb will force data to be written with the FillOrder tag set to LSB2MSB, while −f msb2lsb will force data to be written with the FillOrder tag set to MSB2LSB.

    −i

    Ignore non-fatal read errors and continue processing of the input file.

    −l

    Specify the length of a tile (in pixels). tiffcrop attempts to set the tile dimensions so that no more than 8 kilobytes of data appear in a tile.

    −L

    Force output to be written with Little-Endian byte order. This option only has an effect when the output file is created or overwritten and not when it is appended to.

    −M

    Suppress the use of memory-mapped files when reading images.

    −p

    Specify the planar configuration to use in writing image data that has one 8-bit sample per pixel. By default, tiffcrop will create a new file with the same planar configuration as the original. Specifying −p contig will force data to be written with multi-sample data packed together, while −p separate will force samples to be written in separate planes.

    −r

    Specify the number of rows (scanlines) in each strip of data written to the output file. By default (or when value 0 is specified), tiffcrop attempts to set the rows/strip that no more than 8 kilobytes of data appear in a strip. If you specify special value -1 it will results in infinite number of the rows per strip. The entire image will be the one strip in that case.

    −s

    Force the output file to be written with data organized in strips (rather than tiles).

    −t

    Force the output file to be written with data organized in tiles (rather than strips). options can be used to force the resultant image to be written as strips or tiles of data, respectively.

    −w

    Specify the width of a tile (in pixels). tiffcrop attempts to set the tile dimensions so that no more than 8 kilobytes of data appear in a tile. tiffcrop attempts to set the tile dimensions so that no more than 8 kilobytes of data appear in a tile.

    −,={character}

    substitute {character} for ’,’ in parsing image directory indices in files. This is necessary if filenames contain commas. Note that ’,=’ with whitespace immediately following will disable the special meaning of the ’,’ entirely. See examples.

    EXAMPLES

    The following concatenates two files and writes the result using LZW encoding:

    		 
    tiffcrop -c lzw a.tif b.tif result.tif

    To convert a G3 1d-encoded TIFF to a single strip of G4-encoded data the following might be used:

    		 
    tiffcrop -c g4 -r 10000 g3.tif g4.tif

    (1000 is just a number that is larger than the number of rows in the source file.)

    To extract a selected set of images from a multi-image TIFF file use the -N option described above. Thus, to copy the 1st and 3rd images of image file "album.tif" to "result.tif":

    		 
    tiffcrop -N 1,3 album.tif result.tif

    Given file "CCD.tif" whose first image is a noise bias followed by images which include that bias, subtract the noise from all those images following it (while decompressing) with the command:

    		 
    tiffcrop -c none -b CCD.tif CCD.tif -d 2 result.tif

    int TIFFYCbCrToRGBInit(TIFFYCbCrToRGB *ycbcr, float *luma, float *refBlackWhite");"
    void TIFFYCbCrtoRGB(TIFFYCbCrToRGB *    ycbcr, uint32 Y, int32 Cb, int32 Cr, uint32 *R, uint32 *G, uint32 *B );

    void TIFFXYZToRGB(TIFFCIELabToRGB *    cielab, float X, float Y, float Z",uint32*"R, uint32 *G, uint32 *B);

    DESCRIPTION

    TIFF supports several color spaces for images stored in that format. There is usually a problem of application to handle the data properly and convert between different colorspaces for displaying and printing purposes. To simplify this task libtiff implements several color conversion routines itself. In particular, these routines used in TIFFRGBAImage(3TIFF) interface.

    TIFFYCbCrToRGBInit() used to initialize YCbCr to RGB conversion state. Allocating and freeing of the ycbcr structure belongs to programmer. TIFFYCbCrToRGB defined in tiffio.h as

    		 
    typedef struct {                /* YCbCr->RGB support */
        TIFFRGBValue* clamptab; /* range clamping table */

    int*

    Cr_r_tab;
    int*

    Cb_b_tab;
    int32*

    Cr_g_tab;
    int32*

    Cb_g_tab;

    int32* Y_tab;
    } TIFFYCbCrToRGB;

    luma is a float array of three values representing proportions of the red, green and blue in luminance, Y (see section 21 of the TIFF 6.0 specification, where the YCbCr images discussed). TIFFTAG_YCBCRCOEFFICIENTS holds that values in TIFF file. refBlackWhite is a float array of 6 values which specifies a pair of headroom and footroom image data values (codes) for each image component (see section 20 of the TIFF 6.0 specification where the colorinmetry fields discussed). TIFFTAG_REFERENCEBLACKWHITE is responsible for storing these values in TIFF file. Following code snippet should helps to understand the the technique:

    		 
    float *luma, *refBlackWhite;
uint16 hs, vs;

/* Initialize structures */
ycbcr = (TIFFYCbCrToRGB*)

    _TIFFmalloc(TIFFroundup(sizeof(TIFFYCbCrToRGB), sizeof(long))

    + 4*256*sizeof(TIFFRGBValue)

    + 2*256*sizeof(int)

    + 3*256*sizeof(int32));

    if (ycbcr == NULL) {
    TIFFError("YCbCr->RGB",

    "No space for YCbCr->RGB conversion state");

    exit(0);
    }

    TIFFGetFieldDefaulted(tif, TIFFTAG_YCBCRCOEFFICIENTS, &luma);
    TIFFGetFieldDefaulted(tif, TIFFTAG_REFERENCEBLACKWHITE, &refBlackWhite);
    if (TIFFYCbCrToRGBInit(ycbcr, luma, refBlackWhite) < 0)

    exit(0);

    /* Start conversion */
    uint32 r, g, b;
    uint32 Y;
    int32 Cb, Cr;

    for each pixel in image

    TIFFYCbCrtoRGB(img->ycbcr, Y, Cb, Cr, &r, &g, &b);

    /* Free state structure */
    _TIFFfree(ycbcr);

    TIFFCIELabToRGBInit() initializes the CIE L*a*b* 1976 to RGB conversion state. TIFFCIELabToRGB defined as

    		 
    #define CIELABTORGB_TABLE_RANGE 1500

    display is a display device description, declared as

    		 
    typedef struct {

    float d_mat[3][3]; /* XYZ -> luminance matrix */

    float d_YCR; /* Light o/p for reference white */

    float d_YCG;

    float d_YCB;

    uint32 d_Vrwr; /* Pixel values for ref. white */

    uint32 d_Vrwg;

    uint32 d_Vrwb;

    float d_Y0R; /* Residual light for black pixel */

    float d_Y0G;

    float d_Y0B;

    float d_gammaR; /* Gamma values for the three guns */

    float d_gammaG;

    float d_gammaB;

    } TIFFDisplay;

    For example, the one can use sRGB device, which has the following parameters:

    		 
    TIFFDisplay display_sRGB = {

    { /* XYZ -> luminance matrix */

    { 3.2410F, -1.5374F, -0.4986F },

    { -0.9692F, 1.8760F, 0.0416F },

    { 0.0556F, -0.2040F, 1.0570F }

    },

    100.0F, 100.0F, 100.0F, /* Light o/p for reference white */

    255, 255, 255, /* Pixel values for ref. white */

    1.0F, 1.0F, 1.0F, /* Residual light o/p for black pixel */

    2.4F, 2.4F, 2.4F, /* Gamma values for the three guns */

    };

    refWhite is a color temperature of the reference white. The TIFFTAG_WHITEPOINT contains the chromaticity of the white point of the image from where the reference white can be calculated using following formulae:

    refWhite_Y = 100.0
    refWhite_X = whitePoint_x / whitePoint_y * refWhite_Y
    refWhite_Z = (1.0 - whitePoint_x - whitePoint_y) / whitePoint_y * refWhite_X

    The conversion itself performed in two steps: at the first one we will convert CIE L*a*b* 1976 to CIE XYZ using TIFFCIELabToXYZ() routine, and at the second step we will convert CIE XYZ to RGB using TIFFXYZToRGB(). Look at the code sample below:

    		 
    float   *whitePoint;
float   refWhite[3];

/* Initialize structures */
img->cielab = (TIFFCIELabToRGB *)

    _TIFFmalloc(sizeof(TIFFCIELabToRGB));

    if (!cielab) {

    TIFFError("CIE L*a*b*->RGB",

    "No space for CIE L*a*b*->RGB conversion state.");

    exit(0);

    }

    TIFFGetFieldDefaulted(tif, TIFFTAG_WHITEPOINT, &whitePoint);
    refWhite[1] = 100.0F;
    refWhite[0] = whitePoint[0] / whitePoint[1] * refWhite[1];
    refWhite[2] = (1.0F - whitePoint[0] - whitePoint[1])

    / whitePoint[1] * refWhite[1];

    if (TIFFCIELabToRGBInit(cielab, &display_sRGB, refWhite) < 0) {

    TIFFError("CIE L*a*b*->RGB",

    "Failed to initialize CIE L*a*b*->RGB conversion state.");

    _TIFFfree(cielab);

    exit(0);

    }

    /* Now we can start to convert */
    uint32 r, g, b;
    uint32 L;
    int32 a, b;
    float X, Y, Z;

    for each pixel in image

    TIFFCIELabToXYZ(cielab, L, a, b, &X, &Y, &Z);

    TIFFXYZToRGB(cielab, X, Y, Z, &r, &g, &b);

    /* Don’t forget to free the state structure */
    _TIFFfree(cielab);

    NAME

    fax2ps − convert a TIFF facsimile to compressed PostScript™

    SYNOPSIS

    fax2ps [ options ] [ file ... ]

    DESCRIPTION

    fax2ps reads one or more TIFF facsimile image files and prints a compressed form of PostScript on the standard output that is suitable for printing.

    By default, each page is scaled to reflect the image dimensions and resolutions stored in the file. The −x and −y options can be used to specify the horizontal and vertical image resolutions (lines/inch), respectively. If the −S option is specified, each page is scaled to fill an output page. The default output page is 8.5 by 11 inches. Alternate page dimensions can be specified in inches with the −W and −H options.

    By default fax2ps generates PostScript for all pages in the file. The −p option can be used to select one or more pages from a multi-page document.

    fax2ps generates a compressed form of PostScript that is optimized for sending pages of text to a PostScript printer attached to a host through a low-speed link (such as a serial line). Each output page is filled with white and then only the black areas are drawn. The PostScript specification of the black drawing operations is optimized by using a special font that encodes the move-draw operations required to fill the black regions on the page. This compression scheme typically results in a substantially reduced PostScript description, relative to the straightforward imaging of the page with a PostScript image operator. This algorithm can, however, be ineffective for continuous-tone and white-on-black images. For these images, it sometimes is more efficient to send the raster bitmap image directly; see tiff2ps(1).

    OPTIONS

    −p number

    Print only the indicated page. Multiple pages may be printed by specifying this option more than once.

    −x resolution

    Use resolution as the horizontal resolution, in dots/inch, of the image data. By default this value is taken from the file.

    −y resolution

    Use resolution as the vertical resolution, in lines/inch, of the image data. By default this value is taken from the file.

    −S

    Scale each page of image data to fill the output page dimensions. By default images are presented according to the dimension information recorded in the TIFF file.

    −W width

    Use width as the width, in inches, of the output page.

    −H height

    Use height as the height, in inches, of the output page.

    DIAGNOSTICS

    Some messages about malformed TIFF images come from the TIFF library.

    Various messages about badly formatted facsimile images may be generated due to transmission errors in received facsimile. fax2ps attempts to recover from such data errors by resynchronizing decoding at the end of the current scanline. This can result in long horizontal black lines in the resultant PostScript image.

    NOTES

    If the destination printer supports PostScript Level II then it is always faster to just send the encoded bitmap generated by the tiff2ps(1) program.

    BUGS

    fax2ps should probably figure out when it is doing a poor job of compressing the output and just generate PostScript to image the bitmap raster instead.

    TIFFRGBAImageOK, TIFFRGBAImageBegin, TIFFRGBAImageGet, TIFFRGBAImageEnd − read and decode an image into a raster

    SYNOPSIS

    #include <tiffio.h>

    typedef unsigned char TIFFRGBValue; typedef struct _TIFFRGBAImage TIFFRGBAImage;

    int TIFFRGBAImageOK(TIFF *tif, char emsg[1024])
    int TIFFRGBAImageBegin(TIFFRGBAImage *    img, TIFF* tif, int stopOnError, char emsg[1024])
    int TIFFRGBAImageGet(TIFFRGBAImage *    img, uint32* raster, uint32 width , uint32 height)
    void TIFFRGBAImageEnd(TIFFRGBAImage *    img)

    DESCRIPTION

    The routines described here provide a high-level interface through which TIFF images may be read into memory. Images may be strip- or tile-based and have a variety of different characteristics: bits/sample, samples/pixel, photometric, etc. Decoding state is encapsulated in a TIFFRGBAImage structure making it possible to capture state for multiple images and quickly switch between them. The target raster format can be customized to a particular application’s needs by installing custom routines that manipulate image data according to application requirements.

    The default usage for these routines is: check if an image can be processed using TIFFRGBAImageOK, construct a decoder state block using TIFFRGBAImageBegin, read and decode an image into a target raster using TIFFRGBAImageGet, and then release resources using TIFFRGBAImageEnd. TIFFRGBAImageGet can be called multiple times to decode an image using different state parameters. If multiple images are to be displayed and there is not enough space for each of the decoded rasters, multiple state blocks can be managed and then calls can be made to TIFFRGBAImageGet as needed to display an image.

    The generated raster is assumed to be an array of width times height 32-bit entries, where width must be less than or equal to the width of the image (height may be any non-zero size). If the raster dimensions are smaller than the image, the image data is cropped to the raster bounds. If the raster height is greater than that of the image, then the image data are placed in the lower part of the raster. (Note that the raster is assume to be organized such that the pixel at location (x,y) is raster[y*width+x]; with the raster origin in the lower-left hand corner.)

    Raster pixels are 8-bit packed red, green, blue, alpha samples. The macros TIFFGetR, TIFFGetG, TIFFGetB, and TIFFGetA should be used to access individual samples. Images without Associated Alpha matting information have a constant Alpha of 1.0 (255).

    TIFFRGBAImageGet converts non-8-bit images by scaling sample values. Palette, grayscale, bilevel, CMYK , and YCbCr images are converted to RGB transparently. Raster pixels are returned uncorrected by any colorimetry information present in the directory.

    The parameter stopOnError specifies how to act if an error is encountered while reading the image. If stopOnError is non-zero, then an error will terminate the operation; otherwise TIFFRGBAImageGet will continue processing data until all the possible data in the image have been requested.

    ALTERNATE RASTER FORMATS

    To use the core support for reading and processing TIFF images, but write the resulting raster data in a different format one need only override the ‘‘put methods’’ used to store raster data. These methods are are defined in the TIFFRGBAImage structure and initially setup by TIFFRGBAImageBegin to point to routines that pack raster data in the default ABGR pixel format. Two different routines are used according to the physical organization of the image data in the file: PlanarConfiguration=1 (packed samples), and PlanarConfiguration=2 (separated samples). Note that this mechanism can be used to transform the data before storing it in the raster. For example one can convert data to colormap indices for display on a colormap display.

    SIMULTANEOUS RASTER STORE AND DISPLAY

    It is simple to display an image as it is being read into memory by overriding the put methods as described above for supporting alternate raster formats. Simply keep a reference to the default put methods setup by TIFFRGBAImageBegin and then invoke them before or after each display operation. For example, the tiffgt(1) utility uses the following put method to update the display as the raster is being filled:

    static void
putContigAndDraw(TIFFRGBAImage* img, uint32* raster,
    uint32 x, uint32 y, uint32 w, uint32 h,
    int32 fromskew, int32 toskew,
    unsigned char* cp)
{
    (*putContig)(img, raster, x, y, w, h, fromskew, toskew, cp);
    if (x+w == width) {
     w = width;
     if (img->orientation == ORIENTATION_TOPLEFT)
         lrectwrite(0, y-(h-1), w-1, y, raster-x-(h-1)*w);
     else
         lrectwrite(0, y, w-1, y+h-1, raster);
    }
}

    (the original routine provided by the library is saved in the variable putContig.)

    SUPPORTING ADDITIONAL TIFF FORMATS

    The TIFFRGBAImage routines support the most commonly encountered flavors of TIFF. It is possible to extend this support by overriding the ‘‘get method’’ invoked by TIFFRGBAImageGet to read TIFF image data. Details of doing this are a bit involved, it is best to make a copy of an existing get method and modify it to suit the needs of an application.

    NOTES

    Samples must be either 1, 2, 4, 8, or 16 bits. Colorimetric samples/pixel must be either 1, 3, or 4 (i.e. SamplesPerPixel minus ExtraSamples).

    Palette image colormaps that appear to be incorrectly written as 8-bit values are automatically scaled to 16-bits.

    RETURN VALUES

    All routines return 1 if the operation was successful. Otherwise, 0 is returned if an error was encountered and stopOnError is zero.

    DIAGNOSTICS

    All error messages are directed to the TIFFError(3TIFF) routine.

    Sorry, can not handle %d-bit pictures. The image had BitsPerSample other than 1, 2, 4, 8, or 16.

    Sorry, can not handle %d-channel images. The image had SamplesPerPixel other than 1, 3, or 4.

    Missing needed "PhotometricInterpretation" tag. The image did not have a tag that describes how to display the data.

    No "PhotometricInterpretation" tag, assuming RGB. The image was missing a tag that describes how to display it, but because it has 3 or 4 samples/pixel, it is assumed to be RGB.

    No "PhotometricInterpretation" tag, assuming min-is-black. The image was missing a tag that describes how to display it, but because it has 1 sample/pixel, it is assumed to be a grayscale or bilevel image.

    No space for photometric conversion table. There was insufficient memory for a table used to convert image samples to 8-bit RGB.

    Missing required "Colormap" tag. A Palette image did not have a required Colormap tag.

    No space for tile buffer. There was insufficient memory to allocate an i/o buffer.

    No space for strip buffer. There was insufficient memory to allocate an i/o buffer.

    Can not handle format. The image has a format (combination of BitsPerSample, SamplesPerPixel, and PhotometricInterpretation) that can not be handled.

    No space for B&W mapping table. There was insufficient memory to allocate a table used to map grayscale data to RGB.

    No space for Palette mapping table. There was insufficient memory to allocate a table used to map data to 8-bit RGB.

    DESCRIPTION

    The following routines are provided for client-control of the I/O buffers used by the library. Applications need never use these routines; they are provided only for ‘‘intelligent clients’’ that wish to optimize memory usage and/or eliminate potential copy operations that can occur when working with images that have data stored without compression.

    TIFFReadBufferSetup sets up the data buffer used to read raw (encoded) data from a file. If the specified pointer is NULL (zero), then a buffer of the appropriate size is allocated. Otherwise the caller must guarantee that the buffer is large enough to hold any individual strip of raw data. TIFFReadBufferSetup returns a non-zero value if the setup was successful and zero otherwise.

    TIFFWriteBufferSetup sets up the data buffer used to write raw (encoded) data to a file. If the specified size is −1 then the buffer size is selected to hold a complete tile or strip, or at least 8 kilobytes, whichever is greater. If the specified buffer is NULL (zero), then a buffer of the appropriate size is dynamically allocated. TIFFWriteBufferSetup returns a non-zero value if the setup was successful and zero otherwise.

    DIAGNOSTICS

    %s: No space for data buffer at scanline %ld. TIFFReadBufferSetup was unable to dynamically allocate space for a data buffer.

    DESCRIPTION

    Tiffcmp compares the tags and data in two files created according to the Tagged Image File Format, Revision 6.0. The schemes used for compressing data in each file are immaterial when data are compared−data are compared on a scanline-by-scanline basis after decompression. Most directory tags are checked; notable exceptions are: GrayResponseCurve, ColorResponseCurve, and ColorMap tags. Data will not be compared if any of the BitsPerSample, SamplesPerPixel, or ImageWidth values are not equal. By default, tiffcmp will terminate if it encounters any difference.

    OPTIONS

    −l

    List each byte of image data that differs between the files.

    −z number

    List specified number of image data bytes that differs between the files.

    −t

    Ignore any differences in directory tags.

    BUGS

    Tags that are not recognized by the library are not compared; they may also generate spurious diagnostics.

    The image data of tiled files is not compared, since the TIFFReadScanline() function is used. An error will be reported for tiled files.

    The pixel and/or sample number reported in differences may be off in some exotic cases.

    DESCRIPTION

    Compress size bytes of raw data from buf and write the result to the specified strip; replacing any previously written data. Note that the value of strip is a ‘‘raw strip number.’’ That is, the caller must take into account whether or not the data are organized in separate planes (PlanarConfiguration=2).

    NOTES

    The library writes encoded data using the native machine byte order. Correctly implemented TIFF readers are expected to do any necessary byte-swapping to correctly process image data with BitsPerSample greater than 8.

    The strip number must be valid according to the current settings of the ImageLength and RowsPerStrip tags. An image may be dynamically grown by increasing the value of ImageLength prior to each call to TIFFWriteEncodedStrip.

    RETURN VALUES

    −1 is returned if an error was encountered. Otherwise, the value of size is returned.

    DIAGNOSTICS

    All error messages are directed to the TIFFError(3TIFF) routine.

    %s: File not open for writing. The file was opened for reading, not writing.

    Can not write scanlines to a tiled image. The image is assumed to be organized in tiles because the TileWidth and TileLength tags have been set with TIFFSetField(3TIFF).

    TIFFTileSize, TIFFTileRowSize, TIFFVTileSize, TIFFDefaultTileSize, TIFFComputeTile, TIFFCheckTile, TIFFNumberOfTiles − tile-related utility routines

    SYNOPSIS

    #include <tiffio.h>

    void TIFFDefaultTileSize(TIFF *tif, uint32 *tw, uint32 *th)
    tsize_t TIFFTileSize(TIFF *    tif)
    tsize_t TIFFTileRowSize(TIFF *    tif)
    tsize_t TIFFVTileSize(TIFF *    tif, uint32 nrows)
    ttile_t TIFFComputeTile(TIFF *    tif, uint32 x, uint32 y, uint32 z, tsample_t sample)
    int TIFFCheckTile(TIFF *    tif, uint32 x, uint32 y, uint32 z, tsample_t sample)
    ttile_t TIFFNumberOfTiles(TIFF *    tif)

    DESCRIPTION

    TIFFDefaultTileSize returns the pixel width and height of a reasonable-sized tile; suitable for setting up the TileWidth and TileLength tags. If the tw and th values passed in are non-zero, then they are adjusted to reflect any compression-specific requirements. The returned width and height are constrained to be a multiple of 16 pixels to conform with the TIFF specification.

    TIFFTileSize returns the equivalent size for a tile of data as it would be returned in a call to TIFFReadTile or as it would be expected in a call to TIFFWriteTile.

    TIFFVTileSize returns the number of bytes in a row-aligned tile with nrows of data.

    TIFFTileRowSize returns the number of bytes of a row of data in a tile.

    TIFFComputeTile returns the tile that contains the specified coordinates. A valid tile is always returned; out-of-range coordinate values are clamped to the bounds of the image. The x and y parameters are always used in calculating a tile. The z parameter is used if the image is deeper than 1 slice (ImageDepth>1). The sample parameter is used only if data are organized in separate planes (PlanarConfiguration=2).

    TIFFCheckTile returns a non-zero value if the supplied coordinates are within the bounds of the image and zero otherwise. The x parameter is checked against the value of the ImageWidth tag. The y parameter is checked against the value of the ImageLength tag. The z parameter is checked against the value of the ImageDepth tag (if defined). The sample parameter is checked against the value of the SamplesPerPixel parameter if the data are organized in separate planes.

    TIFFNumberOfTiles returns the number of tiles in the image.

    DIAGNOSTICS

    None.

    Modifying The TIFF Library

    This chapter provides information about the internal structure of the library, how to control the configuration when building it, and how to add new support to the library. The following sections are found in this chapter:

    Library Configuration

     Information on compiling the library is given elsewhere in this documentation. This section describes the low-level mechanisms used to control the optional parts of the library that are configured at build time. Control is based on a collection of C defines that are specified either on the compiler command line or in a configuration file such as port.h (as generated by the configure script for UNIX systems) or tiffconf.h.

    Configuration defines are split into three areas:

    • those that control which compression schemes are configured as part of the builtin codecs,
    • those that control support for groups of tags that are considered optional, and
    • those that control operating system or machine-specific support.

    If the define COMPRESSION_SUPPORT is not defined then a default set of compression schemes is automatically configured:

    • CCITT Group 3 and 4 algorithms (compression codes 2, 3, 4, and 32771),
    • the Macintosh PackBits algorithm (compression 32773),
    • a 4-bit run-length encoding scheme from ThunderScan (compression 32809),
    • a 2-bit encoding scheme used by NeXT (compression 32766), and
    • two experimental schemes intended for images with high dynamic range (compression 34676 and 34677).

    To override the default compression behaviour define COMPRESSION_SUPPORT and then one or more additional defines to enable configuration of the appropriate codecs (see the table below); e.g. 

      #define	COMPRESSION_SUPPORT
#define	CCITT_SUPPORT
#define	PACKBITS_SUPPORT
    Several other compression schemes are configured separately from the default set because they depend on ancillary software packages that are not distributed with libtiff.

    Support for JPEG compression is controlled by JPEG_SUPPORT. The JPEG codec that comes with libtiff is designed for use with release 5 or later of the Independent JPEG Group's freely available software distribution. This software can be retrieved from the directory ftp.uu.net:/graphics/jpeg/.

    NOTE: Enabling JPEG support automatically enables support for the TIFF 6.0 colorimetry and YCbCr-related tags.

    Experimental support for the deflate algorithm is controlled by DEFLATE_SUPPORT. The deflate codec that comes with libtiff is designed for use with version 0.99 or later of the freely available libz library written by Jean-loup Gailly and Mark Adler. The data format used by this library is described in the files zlib-3.1.doc, and deflate-1.1.doc, available in the directory ftp.uu.net:/pub/archiving/zip/doc. The library can be retried from the directory ftp.uu.net:/pub/archiving/zip/zlib/ (or try quest.jpl.nasa.gov:/beta/zlib/).

    NOTE: The deflate algorithm is experimental. Do not expect to exchange files using this compression scheme; it is included only because the similar, and more common, LZW algorithm is claimed to be governed by licensing restrictions.

    By default tiffconf.h defines COLORIMETRY_SUPPORT, YCBCR_SUPPORT, and CMYK_SUPPORT.

    DefineDescription
    CCITT_SUPPORT CCITT Group 3 and 4 algorithms (compression codes 2, 3, 4, and 32771)

    General Portability Comments

    This software is developed on Silicon Graphics UNIX systems (big-endian, MIPS CPU, 32-bit ints, IEEE floating point). The configure shell script generates the appropriate include files and make files for UNIX systems. Makefiles exist for non-UNIX platforms that the code runs on -- this work has mostly been done by other people.

    In general, the code is guaranteed to work only on SGI machines. In practice it is highly portable to any 32-bit or 64-bit system and much work has been done to insure portability to 16-bit systems. If you encounter portability problems please return fixes so that future distributions can be improved.

    The software is written to assume an ANSI C compilation environment. If your compiler does not support ANSI function prototypes, const, and <stdarg.h> then you will have to make modifications to the software. In the past I have tried to support compilers without const and systems without <stdarg.h>, but I am no longer interested in these antiquated environments. With the general availability of the freely available GCC compiler, I see no reason to incorporate modifications to the software for these purposes.

    An effort has been made to isolate as many of the operating system-dependencies as possible in two files: tiffcomp.h and libtiff/tif_<os>.c. The latter file contains operating system-specific routines to do I/O and I/O-related operations. The UNIX (tif_unix.c), Macintosh (tif_apple.c), and VMS (tif_vms.c) code has had the most use; the MS/DOS support (tif_msdos.c) assumes some level of UNIX system call emulation (i.e. open, read, write, fstat, malloc, free).

    Native CPU byte order is determined on the fly by the library and does not need to be specified. The HOST_FILLORDER and HOST_BIGENDIAN definitions are not currently used, but may be employed by codecs for optimization purposes.

    The following defines control general portability:

    BSDTYPES Define this if your system does NOT define the usual BSD typedefs: u_char, u_short, u_int, u_long.
    HAVE_IEEEFP Define this as 0 or 1 according to the floating point format suported by the machine. If your machine does not support IEEE floating point then you will need to add support to tif_machdep.c to convert between the native format and IEEE format.
    HAVE_MMAP Define this if there is mmap-style support for mapping files into memory (used only to read data).
    HOST_FILLORDER Define the native CPU bit order: one of FILLORDER_MSB2LSB or FILLORDER_LSB2MSB
    HOST_BIGENDIAN Define the native CPU byte order: 1 if big-endian (Motorola) or 0 if little-endian (Intel); this may be used in codecs to optimize code

    On UNIX systems HAVE_MMAP is defined through the running of the configure script; otherwise support for memory-mapped files is disabled. Note that tiffcomp.h defines HAVE_IEEEFP to be 1 (BSDTYPES is not defined).

    Types and Portability

    The software makes extensive use of C typedefs to promote portability. Two sets of typedefs are used, one for communication with clients of the library and one for internal data structures and parsing of the TIFF format. There are interactions between these two to be careful of, but for the most part you should be able to deal with portability purely by fiddling with the following machine-dependent typedefs:

    uint8 8-bit unsigned integer tiff.h
    int8 8-bit signed integer tiff.h
    uint16 16-bit unsigned integer tiff.h
    int16 16-bit signed integer tiff.h
    uint32 32-bit unsigned integer tiff.h
    int32 32-bit signed integer tiff.h
    dblparam_t promoted type for floats tiffcomp.h

    (to clarify dblparam_t, it is the type that float parameters are promoted to when passed by value in a function call.)

    The following typedefs are used throughout the library and interfaces to refer to certain objects whose size is dependent on the TIFF image structure:

    typedef unsigned int ttag_t; directory tag
    typedef uint16 tdir_t; directory index
    typedef uint16 tsample_t; sample number
    typedef uint32 tstrip_t; strip number
    typedef uint32 ttile_t; tile number
    typedef int32 tsize_t; i/o size in bytes
    typedef void* tdata_t; image data ref
    typedef void* thandle_t; client data handle
    typedef int32 toff_t; file offset (should be off_t)
    typedef unsigned char* tidata_t; internal image data

    Note that tstrip_t, ttile_t, and tsize_t are constrained to be no more than 32-bit quantities by 32-bit fields they are stored in in the TIFF image. Likewise tsample_t is limited by the 16-bit field used to store the SamplesPerPixel tag. tdir_t constrains the maximum number of IFDs that may appear in an image and may be an arbitrary size (without penalty). ttag_t must be either int, unsigned int, pointer, or double because the library uses a varargs interface and ANSI C restricts the type of the parameter before an ellipsis to be a promoted type. toff_t is defined as int32 because TIFF file offsets are (unsigned) 32-bit quantities. A signed value is used because some interfaces return -1 on error (sigh). Finally, note that tidata_t is used internally to the library to manipulate internal data. User-specified data references are passed as opaque handles and only cast at the lowest layers where their type is presumed.

    General Comments

    The library is designed to hide as much of the details of TIFF from applications as possible. In particular, TIFF directories are read in their entirety into an internal format. Only the tags known by the library are available to a user and certain tag data may be maintained that a user does not care about (e.g. transfer function tables).

    Adding New Builtin Codecs

     To add builtin support for a new compression algorithm, you can either use the "tag-extension" trick to override the handling of the TIFF Compression tag (see Adding New Tags), or do the following to add support directly to the core library:
    1. Define the tag value in tiff.h.
    2. Edit the file tif_codec.c to add an entry to the _TIFFBuiltinCODECS array (see how other algorithms are handled).
    3. Add the appropriate function prototype declaration to tiffiop.h (close to the bottom).
    4. Create a file with the compression scheme code, by convention files are named tif_*.c (except perhaps on some systems where the tif_ prefix pushes some filenames over 14 chars.
    5. Edit Makefile.in (and any other Makefiles) to include the new source file.

    A codec, say foo, can have many different entry points: 

    TIFFInitfoo(tif, scheme)/* initialize scheme and setup entry points in tif */
fooSetupDecode(tif)	/* called once per IFD after tags has been frozen */
fooPreDecode(tif, sample)/* called once per strip/tile, after data is read,
			    but before the first row is decoded */
fooDecode*(tif, bp, cc, sample)/* decode cc bytes of data into the buffer */
    fooDecodeRow(...)	/* called to decode a single scanline */
    fooDecodeStrip(...)	/* called to decode an entire strip */
    fooDecodeTile(...)	/* called to decode an entire tile */
fooSetupEncode(tif)	/* called once per IFD after tags has been frozen */
fooPreEncode(tif, sample)/* called once per strip/tile, before the first row in
			    a strip/tile is encoded */
fooEncode*(tif, bp, cc, sample)/* encode cc bytes of user data (bp) */
    fooEncodeRow(...)	/* called to decode a single scanline */
    fooEncodeStrip(...)	/* called to decode an entire strip */
    fooEncodeTile(...)	/* called to decode an entire tile */
fooPostEncode(tif)	/* called once per strip/tile, just before data is written */
fooSeek(tif, row)	/* seek forwards row scanlines from the beginning
			   of a strip (row will always be >0 and <rows/strip */
fooCleanup(tif)		/* called when compression scheme is replaced by user */

    Note that the encoding and decoding variants are only needed when a compression algorithm is dependent on the structure of the data. For example, Group 3 2D encoding and decoding maintains a reference scanline. The sample parameter identifies which sample is to be encoded or decoded if the image is organized with PlanarConfig=2 (separate planes). This is important for algorithms such as JPEG. If PlanarConfig=1 (interleaved), then sample will always be 0.

    Other Comments

    The library handles most I/O buffering. There are two data buffers when decoding data: a raw data buffer that holds all the data in a strip, and a user-supplied scanline buffer that compression schemes place decoded data into. When encoding data the data in the user-supplied scanline buffer is encoded into the raw data buffer (from where it is written). Decoding routines should never have to explicitly read data -- a full strip/tile's worth of raw data is read and scanlines never cross strip boundaries. Encoding routines must be cognizant of the raw data buffer size and call TIFFFlushData1() when necessary. Note that any pending data is automatically flushed when a new strip/tile is started, so there's no need do that in the tif_postencode routine (if one exists). Bit order is automatically handled by the library when a raw strip or tile is filled. If the decoded samples are interpreted by the decoding routine before they are passed back to the user, then the decoding logic must handle byte-swapping by overriding the tif_postdecode routine (set it to TIFFNoPostDecode) and doing the required work internally. For an example of doing this look at the horizontal differencing code in the routines in tif_predict.c.

    The variables tif_rawcc, tif_rawdata, and tif_rawcp in a TIFF structure are associated with the raw data buffer. tif_rawcc must be non-zero for the library to automatically flush data. The variable tif_scanlinesize is the size a user's scanline buffer should be. The variable tif_tilesize is the size of a tile for tiled images. This should not normally be used by compression routines, except where it relates to the compression algorithm. That is, the cc parameter to the tif_decode* and tif_encode* routines should be used in terminating decompression/compression. This ensures these routines can be used, for example, to decode/encode entire strips of data.

    In general, if you have a new compression algorithm to add, work from the code for an existing routine. In particular, tif_dumpmode.c has the trivial code for the "nil" compression scheme, tif_packbits.c is a simple byte-oriented scheme that has to watch out for buffer boundaries, and tif_lzw.c has the LZW scheme that has the most complexity -- it tracks the buffer boundary at a bit level. Of course, using a private compression scheme (or private tags) limits the portability of your TIFF files.

    • bugs in handling unknown tags have been corrected; applications that use multiple codecs, each with codec-specific tags, no longer generate confusing error messages
    • a missing pseudo-tag definition in the CCITT G3 codec was fixed (this problem caused core dumps in the tiffcp program)
    • pseudo-tags are now treated specially; they are always considered to be set (i.e. they do not use bits in the FIELD_* bit-vectors).
    • the use of strip chopping can now be controlled on a per-file basis through a mode parameter supplied when opening a file (``C'' to enable strip chopping and ``c'' to disable)
    • two bugs were fixed in the writing of opposite-endian byte-order files
    • support was added for three new fax-related tags registered to SGI: FaxRecvParams, FaxRecvTime, and FaxSubAddress
    • the bit order of image data read and written can now be controlled on a per-file basis through a mode parameter supplied when opening a file (``B'' to force MSB2LSB bit order, ``L'' for LSB2MSB bit order, and ``H'' for the bit order of the native CPU)
    • the byte order of image and tag data written to newly-created files can now be controlled on a per-file basis through a mode parameter supplied when openening a file (``b'' to force Big-Endian byte order and ``l'' to force Little-Endian byte order)
    • the use memory-mapped files for images opened read-only can now be controlled on a per-file basis through a mode parameter supplied when opening a file (``M'' to enable use of memory-mapped files and ``m'' to disable use)
    • the use of the WIN32 define in tiffiop.h has been replaced by __WIN32__

    The ChangeLog will follow, but please note the most important change: LZW compression has been removed.

    Unisys has the patent on LZW compression and have been very active in their enforcement of late, demanding payments of $5000 or more from websites using unlicensed software to create GIF's. They could well do the same do persons using libtiff to create LZW compressed TIFF images.

    From Burn All GIF's Day:
    The catch is that it appears to be difficult or impossible to get a Unisys license to use LZW in free software that complies with the Open Source Definition

    Unfortunatly, the removal of LZW compression means that saved image size has grown dramatically. Without a change in the TIFF spec to support another lossless compression format, this is unavoidable.

    The library can use zip for lossless compression, but as this is not part of the spec, TIFFs using zip compression may not work with other software

    We will be making a patch available that will contain the LZW compression code for users who have either obtained a license from Unisys or are willing to risk it.

    LZW decompression is unchanged.

    CHANGES IN THE SOFTWARE CONFIGURATION:
    • Added zip creation to release makefile target

    CHANGES IN LIBTIFF:
    • Added html for TIFFWriteTile.3t man page.
    • Added some changes to tif_write.c to support rewriting existing fixed sized tiles and strips. Code mods disabled by default, only enabled if REWRITE_HACK is defined for now.
    • Added TIFFWriteTile.3t man page.
    • Added notes on use of makefile.vc in build.html, and fixed email subscription address.
    • Fixed apocalypse-inducing y2k bug in contrib/ras/ras2tiff.c
    • Did some casts cleaning up to reduce compiler warnings in tif_fax3.c, from Bruce Carmeron -- modifications of changes made by Frank (sun cc still complained on cast).
    • fixed various VC++ warnings as suggested by Gilles Vollant .
    • Modified TIFFquery.3t man pages info on TIFFIsByteSwapped() to not imply applications are responsible for image data swapping.
    • HTML-ized the man pages, added to html/man
    • Removed LZW Compression to comply with Unisys patent extortion.
    • Corrected one remaining 16 -> 32 bit value in tif_fax3.c, From Ivo Penzar Added patch from Ivo Penzar to have TiffAdvanceDirectory handle memory mapped files.

    MAJOR CHANGES:

    BigTIFF support changes:
    • The options parameter in the TIFFOpen and TIFFClientOpen funcs has been extended. When creating new files, you can add option '4' to specify you want to create a ClassicTIFF file, though that is the default and the option is not strictly necessary. (As such, old calling code will continue to function and create ClassicTIFF files.) Or you can add option '8' to specify you want to create a BigTIFF file instead. This new option is also reflected in some of the tools we already upgraded. For instance, you can use the -8 option on tiffcp to have tiffcp produce BigTIFF files instead of the default ClassicTIFF. (Whilst on additional option is provided for version selection when creating new files, no such option is necessary when reading TIFF files. LibTiff reads ClassicTIFF and BigTIFF both, and the application does not need to be aware which TIFF version an opened file is.)
    • Although the tag count in BigTIFF is 64bit, we restricted the count in the implementation to a much more reasonable size. This is necessary in current implementation, because all tag data gets read automatically in the IFD reading stage, so if there's half a dozen private tags with multiple gigabytes of data that causes considerable overhead even if the application level is never interested in these tags. Our choice to ignore tags with data longer then a certain sanity value is much needed as things stand. We also recommend to step away from writing tiles that are 8 kilobyte in their uncompressed form, or writing single-line strips, in really big files, resulting in mega's of tiles or strips. It's much more efficient to choose bigger tile or strip sizes, up to several megabyte if needed, and have a few kilo of tiles or strips instead.
    • Although it's rare, some application code does directly access file offsets. Some of these are automatically upgraded because they used the toff_t type, others need to be aware that the datatype changed and need to start using toff_t or uint64. This impacts access to tags like the EXIF IFD tag, for example, or the SubIfds tag, or to StripOffsets or TileOffsets, the return type of functions like TIFFCurrentDirOffset, and a parameter type to functions like TIFFSetSubDirectory.
    • Although it's rare, some application code does use structures like TIFFHeader or TIFFDirEntry that used to be an exact binary representation of TIFF structures. These need to change. The old TIFFHeader structure is replaced by the new TIFFHeaderClassic, TIFFHeaderBig, and TIFFHeaderCommon structures that are an exact binary representation of the ClassicTIFF and BigTIFF header, and of the part that is common to both. There is no new equivalent for the old TIFFDirEntry structure (or more precisely, there is still a TIFFDirEntry structure, but it is changed, moved to library-private definition, and no longer an exact binary representation of the tag structure of either TIFF version).
    • Sizer functions, like TIFFTileSize or TIFFScanlineSize and the like, return a tmsize_t value (tmsize_t is defined as int32 on 32bit machines, and int64 on 64bit machines, and as such it is meant to represent signed memory sizes). This is because we figure 98% of the calling code uses the return value as sizes in allocations and the like. So, any overflow that is theoretically possible with BigTIFF when LibTiff is running on a 32bit system, is best detected inside the sizer functions and it is best to return a type that makes sense as a memory size. If your calling code is the exception and is interested in actual file size, you best use the newer TIFFTileSize64 or TIFFScanlineSize64 function that returns an uint64 type.
    • These TIFF tags require a 64-bit type as an argument in libtiff 4.0.0:
      • TIFFTAG_FREEBYTECOUNTS
      • TIFFTAG_FREEOFFSETS
      • TIFFTAG_STRIPBYTECOUNTS
      • TIFFTAG_STRIPOFFSETS
      • TIFFTAG_TILEBYTECOUNTS
      • TIFFTAG_TILEOFFSETS
    Other important backward incompatible changes in the public API:
    • TIFFRewriteField() renamed into _TIFFRewriteField() and moved out from the public interface (from tiffio.h to tiffiop.h). Type of its 'count' parameter changed from uint32 to tmsize_t.
    • TIFFMergeFieldInfo() returns non-void result now. It returns 0 if successful and -1 if failed. Though this is now obsoleted function and should not be used in new programs. Use the new tag extension scheme instead.
    • TIFFFieldWithTag() and TIFFFieldWithName() functions now return pointer to TIFFField constant object instead of TIFFFieldInfo.
    • TIFFReassignTagToIgnore() function and TIFFIgnoreSense enumeration have been removed. They was unused and never been used properly. Should be unneeded for high-level applications.
    • TIFFTagValue structure removed from the public tiffio.h to private tif_dir.h and not accessible anymore. It should be unneeded for high-level applications.

    CHANGES IN THE SOFTWARE CONFIGURATION:

    • Updated autotools: Autoconf 2.68, Automake 1.11.1, libtool 2.4.
    • Enabled support for Automake silent build rules (--enable-silent-rules or 'make V=0')
    • Enabled support for Automake colorized and parallel tests.
    • Added detection of 64-bit integer types since libtiff 4.0 requires use of 64-bit signed and unsigned integer types.
    • Libtiff now provides a more comprehensive test suite with over 72 tests, which may be executed on Unix-like systems, or under Microsoft Windows using MinGW/MSYS or Cygwin.
    • --disable-lzma configure option to disable use of liblzma.
    • --enable-defer-strile-load configure option to enable experimental deferred strip/tile offset/size loading. May cause some extremely sophisticated uses of libtiff to fail.
    • --enable-chunky-strip-read configure option to enable experimental enable reading large strips in chunks in TIFFReadScanline().
    • Now always uses WIN32 native I/O functions for Microsoft Windows except for under Cygwin.
    • Now provides a pkg-config support file (libtiff-4.pc).

    CHANGES IN LIBTIFF:

    • Patches/fixes made to stable libtiff (v3.9.X) are also applied to 4.0.0. There are too many to list here. See the distribution ChangeLog for a detailed change list.
    • There is considerable change in some files like tif_dirread and tif_dirwrite. These changes don't impact backwards compatibility, they are mostly a clean rewrite that does allow BigTIFF support as well as somewhat more robust reading of the unexpected already and will also serve future API extension but does not impact current API or functionality in a negative way that you need to know about.
    • Although there is still a functional definition for types like toff_t (file offset), tstrip_t (strip index number), etc, we recommend against using these in newer code. We have learned that it is next to impossible to use these consistently and make real abstraction of the binary format of these types. Instead, at a certain level we always end up doing casts anyway, and taking the exact binary format into account, so these types are nothing but dangerously misleading and obfuscating. You do not need to update calling code that uses them, as 99.9% of such code will continue to work. But we recommend against using them in newer calling code, and we started replacing them with binary clear types like uint16, uint32 and such in the library.
    • We do use and will continue to use one functional type that is an exception to the above rule, being tmsize_t. This is a signed memory size type, i.e. it is int32 on 32bit machines, or int64 on 64bit machines.
    • Optionally support LZMA compression via TIFF tag 34925. Tiffcp supports compression levels similar to "-c lzma:p1" or "-c zip:p9 for setting the LZMA compression parameters.
    • Optionally defer the load of strip/tile offset and size tags for optimized scanning of directories. Enabled with the --enable-defer-strile-load configure option (DEFER_STRILE_LOAD #define in tif_config.h).
    • Optionally enable experimental support for reading big strips in chunks. Enabled with the --enable-chunky-strip-read configure option.

    CHANGES IN THE TOOLS:

    • tiffset: add -d and -sd switches to allow operation on a particular directory, not just the first.

    This document describes the changes made to the software between the previous and current versions (see above). If you don't find something listed here, then it was not done in this timeframe, or it was not considered important enough to be mentioned. The following information is located here:

    CHANGES IN THE SOFTWARE CONFIGURATION:
    • libtiff/libtiff.def: Brent Roman submitted new version adding serveral missing entry points. Also add a few other entry points later.
    • configure, Makefile.in, etc: added support for OPTIMIZER being set from config.site.
    • config.guess: updated wholesale to an FSF version apparently from 1998 (as opposed to 1994). This is mainly inspired by providing for MacOS X support.
    • configure/config.site: modified to check if -lm is needed for MACHDEPLIBS if not supplied by config.site. Needed for Darwin.
    • libtiff/tiff.h: Applied hac to try and resolve the problem with the inttypes.h include file on AIX. (Bug 39)
    • configure, *Makefile.in: Various changes to improve configuration for HP/UX specifically, and also in general. (Bug 40) They include:
      • Try to handle /usr/bin/sh instead of /bin/sh where necessary.
      • Upgrade to HP/UX 10.x+ compiler, linker and dso options.
      • Fixed mmap() test to avoid MMAP_FIXED ... it isn't available on HP
      • Use -${MAKEFLAGS} in sub makes from makefiles.
      • Fixed SCRIPT_SH/SHELL handling.
    • configure: Changes for DSO generation on AIX provided by John Marquart .
    • configure, libtiff/Makefile.in: Modified to build DSOs properly on Darwin thanks to Robert Krajewski (rpk@alum.mit.edu) and Keisuke Fujii (fujiik@jlcuxf.kek.jp).
    • configure, libtiff/Makefile.in: applied OpenBSD patches as per bug 61.
    • Makefile.in: added DESTDIR support as per bug 60.
    • libtiff/tif_jpeg.c: Define HAVE_BOOLEAN on windows if RPCNDR.H has been included.
    • man/Makefile.in: add TIFFClientOpen link as per debian submitted bug 66.
    • libtiff/Makefile.in: Fixed @DSOSUB_VERSION to be @DSOSUF_VERSION@ in two places.

    CHANGES IN LIBTIFF:
    • tif_fax3.c: keep rw_mode flag internal to fax3 state to remember whether we are encoding or decoding. This is to ensure graceful recovery if TIFFClientOpen() discovers an attempt to open a compressed file for "r+" access, and subsequently close it, as it resets the tif_mode flag to O_RDONLY in this case to avoid writes, confusing the compressor's concept of whether it is in encode or decode mode.
    • tif_luv.c/tiff.h/tiffio.h: New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward (greg@shutterfly.com). He writes:
      1. I improved the gamut-mapping function in tif_luv.c for imaginary colors, because some images were being super-saturated on the input side and this resulted in some strange color shifts in the output.
      2. I added a psuedotag in tiff.h to control random dithering during LogLuv encoding. This is turned off by default for 32-bit LogLuv and on for 24-bit LogLuv output. Dithering improves the average color accuracy over the image.
      3. I added a #define for LOG_LUV_PUBLIC, which is enabled by default in tiffio.h, to expose internal routines for converting between LogLuv and XYZ coordinates. This is helpful for writing more efficient, specialized conversion routines, especially for reading LogLuv files.
    • libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS.
    • Added TIFFTAG_COPYRIGHT support.
    • tif_getimage.c: Added support for 16bit minisblack/miniswhite images in RGBA interface.
    • libtiff/tif_dirinfo.c: removed duplicate TIFFTAG_PHOTOSHOP as per bug 44.
    • libtiff/tif_dirwrite.c: Added support for TIFF_VARIABLE2 in the case of writing TIFF_BYTE/TIFF_SBYTE fields as per bug 43.
    • libtiff/tif_dirinfo.c: Modified the TIFF_BYTE definition for TIFFTAG_PHOTOSHOP to use a writecount of TIFF_VARIABLE2 (-3) to force use of uint32 counts instead of short counts.
    • libtiff/tif_dirinfo.c: moved pixar and copyright flags to ensure everything is in order.
    • Integrated experimental OJPEG support from Scott Marovich of HP.
    • libtiff/tif_open.c: Seek back to zero after failed read, before writing header.
    • libtiff/tiff.h, libtiff/tif_fax3.c: added check for __LP64__ when checking for 64 bit architectures as per bugzilla bug 67.
    • libtiff/tif_getimage.c: Use memmove() instead of TIFFmemcpy() in TIFFReadRGBATile() to avoid issues in cases of overlapping buffers. See Bug 69 in Bugzilla.
    • libtiff/tif_getimage.c: Don't complain for CMYK (separated) images with more than four samples per pixel as per bug 73.
    • libtiff/tif_getimage.c: relax handling of contig case where there are extra samples that are supposed to be ignored as per bug 75. This should now work for 8bit greyscale or palletted images.
    • libtiff/tif_packbits.c: fixed memory overrun error as per bug 77.
    • libtiff/tif_getimage.c: Fixed problem with reading strips or tiles that don't start on a tile boundary. Fix contributed by Josep Vallverdu (from HP), and further described in bug 47.
    • libtif/tif_fax3.c: Removed #ifdef PURIFY logic, and modified to always use the "safe" version, even if there is a very slight cost in performance as per bug 54.
    • libtiff/tif_lzw.c: added dummy LZWSetupEncode() to report an error about LZW not being available.
    • libtiff/tif_dir.c: propagate failure to initialize compression back from TIFFSetField() as an error status, so applications can detect failure.
    • libtiff/tif_lzw.c: Avoid MS VC++ 5.0 optimization bug as per bug 78.
    • libtiff/tif_dirwrite.c: added TIFFRewriteDirectory() function. Updated TIFFWriteDirectory man page to include TIFFRewriteDirectory.
    • libtiff/tiff.h: I have created COMPRESSION_CCITT_T4, COMPRESSION_CCITT_T6, TIFFTAG_T4OPTIONS and TIFFTAG_T6OPTIONS aliases in keeping with TIFF 6.0 standard in tiff.h as per bug 83.
    • Added PHOTOMETRIC_ITULAB as per bug 90.

    CHANGES IN THE TOOLS:
    • Brent Roman contributed updated tiffcp utility (and tiffcp.1) with support for extracting subimages with the ,n syntax, and also adding the -b bias removal flag.
    • tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by Bruce A. Mallett, including a faster encoder, fixes for level 2 PostScript, and support for the imagemask operator.
    • fax2ps.c: Helge (libtiff at oldach.net) submitted fix that corrects behaviour for non-Letter paper sizes. (Bug 35) It fixes two problems:
      Without scaling (-S) the fax is now centered on the page size specified with -H and/or -W. Before, fax2ps was using an obscure and practially useless algorithm to allocate the image relative to Letter sized paper which sometime sled to useless whitespace on the paper, while at the same time cutting of the faxes printable area at the opposite border.
      Second, scaling now preserves aspect ratio, which makes unusual faxes (in particular short ones) print properly.
    • thumbnail.c: changed default output compression to packbits from LZW since LZW isn't generally available.
    • tiff2rgba.c: added -n flag to avoid emitting alpha component. Also added a man page for tiff2rgba.
    • tiffcmp.c: Fixed multi samples per pixel support for ContigCompare as per bug 53. Updated bug section of tiffcmp.1 to note tiled file issues.
    • libtiff/tif_getimage.c: Fixed so that failure is properly reported by gtTileContig, gtStripContig, gtTileSeparate and gtStripSeparate as per bug 51.

    CHANGES IN THE LZW COMPRESSION KIT:
    • Rewrote lzw patching process so that is required to enable full LZW support is to drop the tif_lzw.c from the libtiff-lzw-compression-kit over the one in the libtiff directory.
    • Some changes were made to make recovery from failure to initialize the LZW compressor more graceful.
    • Note that as distributed libtiff support LZW decompression, but not LZW compression.
    CHANGES IN THE CONTRIB AREA:
    • Fixed distribution to include contrib/addtiffo/tif_ovrcache.{c,h}.
    TIFF home page.

    MAJOR CHANGES:
    • This is a bug-fix release for several bugs (two of which are dire) which were discovered in the 3.9.0 release.

    CHANGES IN THE SOFTWARE CONFIGURATION:
    • Several defines were missing from tif_config.vc.h which are necessary to compile the library using MSVC.

    CHANGES IN LIBTIFF:
    • libtiff/tif_write.c (TIFFAppendToStrip): Remove cast which caused libtiff to output a wrong last strip with byte-count and strip-offset of zero. This cast was added on the day of the 3.9.0 release.
    • libtiff/tif_dirwrite.c: Back out changes from 2007-11-22 that resulted in the final strip not being written in some circumstances. http://bugzilla.maptools.org/show_bug.cgi?id=2088

    This document describes the changes made to the software between the previous and current versions (see above). If you don't find something listed here, then it was not done in this timeframe, or it was not considered important enough to be mentioned. The following information is located here:

    MAJOR CHANGES:

    CHANGES IN THE SOFTWARE CONFIGURATION:
    • libtiff/makefile.vc, tools/makefile.vc: Support for IJG JPEG library.
    • Makefile.in: Add an absolute path to the test_pics.sh call.
    • Makefile.in: Add an absolute path to the test_pics.sh call.

    • configure, libtiff/{Makefile.in, mkversion.c}: Relative buildings fixed.
    • Makefile.in: Add an absolute path to the test_pics.sh call.

    CHANGES IN LIBTIFF:
    • libtiff/{tif_color.c, tif_getimage.c, tiffio.h}: Added support for ReferenceBlackWhite tag handling when converted from YCbCr color space as per bug 120.
    • libtiff/{tif_getimage.c, tif_aux.c}: Read WhitePoint tag from the file and properly use it for CIE Lab 1976 to RGB transform.
    • libtiff/{tif_getimage.c, tiffio.h}: Finally resolved problems with orientation handling. TIFFRGBAImage interface now properly supports all possible orientations, i.e. images will be flipped both in horizontal and vertical directions if required. 'Known bugs' section now removed from the appropriate manual pages.
    • libtiff/tif_luv.c: Fixed bug in 48-bit to 24-bit conversion routine, reported by Antonio Scuri.
    • libtiff/{tiffio.h, tif_codec.c}: Added new function TIFFIsCODECConfigured(), suggested by Ross Finlayson.
    • libtiff/tif_ojpeg.c: TIFFVGetField() function now can properly extract the fields from the OJPEG files. Patch supplied by Ross Finlayson.
    • libtiff/tif_dir.h: _TIFFFindOrRegisterdInfo declaration replaced with _TIFFFindOrRegisterFieldInfo as reported by Ross Finlayson.
    • libtiff/tif_dirinfo.c: Implemented binary search in _TIFFMergeFieldInfo(). Patch supplied by Ross Finlayson.

    • libtiff/{tif_color.c, tif_getimage.c, tiffio.h}: New color space conversion code: CIE L*a*b* 1976 images now supported by the TIFFRGBAImage interface. YCbCr to RGB conversion code also moved there and now has publicly available interface. These routines currently used in TIFFRGBAImage interface only and not supported in other libtiff tools yet. So if you want, for example, to convert CIE Lab image into PostScript file you should do it in two steps: chnge colorspace to RGB using tiff2rgba utility abd then process it with the tiff2ps.
    • libtiff/tif_tile.c: Remove spurious use of "s" (sample) in the planarconfig_contig case in TIFFComputeTile() as per bug 387
    • libtiff/tiffiop.h: New macros: TIFFmax and TIFFmin.
    • libtiff/{tiffio.h, tif_strip.c}: Added TIFFRawStripSize() function as suggested by Chris Hanson.
    • libtiff/{tif_lzw.c, tif_fax3.c}: Proper support for update mode as per bug 424.

    CHANGES IN THE TOOLS:
    • tiff2pdf: New tool, written by Ross Finlayson, to directly convert TIFF files to PDF.
    • tiffgt: Unmaintained and platform dependent sgigt utility removed and replaced with the completely rewritten portable tiffgt tool (depend on OpenGL and GLUT). This tool will not build by default.
    • ras2tiff: Properly determine SUN Rasterfiles with the reverse byte order (it is reported by the magic header field). Problem reported by Andreas Wiesmann.
    • raw2tiff: Implemented image size guessing using correlation coefficient calculation between two neighbour lines.

    CHANGES IN THE CONTRIB AREA:
    • contrib/pds/{tif_pdsdirread.c, tif_pdsdirwrite.c}: Use TIFFDataWidth() function insted of tiffDataWidth array.
    CHANGES IN THE LZW COMPRESSION KIT:
    • Proper support for update mode as per bug 424.

    This document describes the changes made to the software between the previous and current versions (see above). If you don't find something listed here, then it was not done in this timeframe, or it was not considered important enough to be mentioned. The following information is located here:

    CHANGES IN THE SOFTWARE CONFIGURATION:
    • It is now possible to setup the software to build only the library; configure reconizes this is the intent when the VERSION, tiff.alpha, and tif_version.c files are in the local directory (i.e. ``.'')
    • configure no longer tries to setup HTML materials
    • include file directories needed in building the library are now specified with a DIRS_LIBINC config parameter
    • configure no longer checks for alternate compilers if CC is set; if the specified compiler is not found or is not appropriate the configuration procedure aborts
    • the port.h file generated by configure is now used only by the library and as such as have been moved to the libtiff directory
    • there is beginning support for building DSO's on systems other than IRIX
    • configure now verifies the JPEG and zlib directory pathnames by checking for well-known include files in these directories
    • configure no longer creates the dist directory needed only on SGI machines (for building SGI binary distributions)
    • a bug was fixed whereby configure would incorrectly set ENVOPTS when building the software with gcc under AIX

    CHANGES IN LIBTIFF:
    • two new typedefs were added to tiff.h: int8 and uint8 for signed and unsigned 8-bit quantities, respectively; these are currently used only by programs in the tools directory
    • the BadFaxLines, CleanFaxData, and ConsecutiveBadFaxLines tags are now supported with Group 4 compression
    • byte order is now correctly identified on 64-bit machines
    • a bug was fixed in the PackBits decoder where input data would appear short when a no-op run was present
    • a bug was fixed in calculations with very wide strips
    • TIFFWriteEncodedStrip and TIFFWriteRawStrip were extended to support dynamically growing the number of strips in an image (must set ImageLength prior to making calls though)
    • TIFFDefaultTileSize now rounds tile width and height up to a multiple of 16 pixels, as required by the TIFF 6.0 specification
    • the file version.h is now built by a new mkversion program; this was done for portability to non-UNIX systems
    • support was added for the Acorn RISC OS (from Peter Greenham)
    • the builtin codec table is now made const when compiling under VMS so that libtiff can be built as a shared library
    • support for the PowerPC Mac (from Ruedi Boesch)
    • support for Window NT/Window 95 (from Scott Wagner)

    CHANGES IN THE TOOLS:
    • the tools no longer include port.h
    • various portability fixes; mostly to eliminate implicit assumptions about how long int32 data types are
    • PostScript Level II additions to tiff2ps from Bjorn Brox
    • sgi2tiff now handles RGBA images

    CHANGES IN THE MANUAL PAGES:
    • the documentation has been updated to reflect the current state of the software
    • some routines have been moved to different manual pages to group like-routines together

    CHANGES IN THE CONTRIBUTED SOFTWARE:
    • support was added for the Acorn RISC OS (from Peter Greenham)
    • support for Windows NT/Windows 95 contributed for a previous version of this software was sort of incorporated (it's broken right now) (from Scott Wagner)

    This document describes the changes made to the software between the previous and current versions (see above). If you don't find something listed here, then it was not done in this timeframe, or it was not considered important enough to be mentioned. The following information is located here:

    CHANGES IN THE SOFTWARE CONFIGURATION:
    • various fixups and subtle improvements to configure from Richard Mlynarik

    CHANGES IN LIBTIFF:
    • a new codec from Pixar designed for high-resolution color images; note that this codec is not configured by default
    • a bug fix for reading tags with a single FLOAT value
    • change to the TIFFGetField calling convention: a tag that has a single value of type DOUBLE is now retrieved by passing a ``double*'' instead of a ``double**'' (this change makes the handling of tags with DOUBLE values identical to the handling of tags with FLOAT values)
    • fix to VMS support for the handling of floating point values

    CHANGES IN THE TOOLS:
    • tiffdump now handles tags with FLOAT and DOUBLE values

    CHANGES IN THE CONTRIBUTED SOFTWARE:
    • updates to the Acorn OS support from Peter Greenham

    TIFF 6.0 Specification Coverage

    The library is capable of dealing with images that are written to follow the 5.0 or 6.0 TIFF spec. There is also considerable support for some of the more esoteric portions of the 6.0 TIFF spec.


    Core requirements

    Both "MM" and "II" byte orders are handled. Both packed and separated planar configuration of samples. Any number of samples per pixel (memory permitting). Any image width and height (memory permitting). Multiple subfiles can be read and written. Editing is not supported in that related subfiles (e.g. a reduced resolution version of an image) are not automatically updated.

    Tags handled: ExtraSamples, ImageWidth, ImageLength, NewSubfileType, ResolutionUnit. Rowsperstrip, StripOffsets, StripByteCounts, XResolution, YResolution

    Tiled Images TileWidth, TileLength, TileOffsets, TileByteCounts

    Class G for grayscale images SamplesPerPixel = 1
    BitsPerSample = 4, 8

    (Class Y tags if YCbCr)
    (Class S tags if CMYK)
    Compression = 7 (JPEG)

    In addition, the library supports some optional compression algorithms that are, in some cases, of dubious value.

    Compression tag valueCompression algorithm
    32766NeXT 2-bit encoding
    32809ThunderScan 4-bit encoding
    32909Pixar companded 11-bit ZIP encoding

    34676SGI 32-bit Log Luminance encoding (experimental)
    34677SGI 24-bit Log Luminance encoding (experimental)

    Note that there is no support for the JPEG-related tags defined in the 6.0 specification; the JPEG support is based on the post-6.0 proposal given in TIFF Technical Note #2.

    For more information on the experimental Log Luminance encoding consult the materials available at http://www.anyhere.com/gward/pixformat/tiffluv.html.

    The following table shows the tags that are recognized and how they are used by the library. If no use is indicated, then the library reads and writes the tag, but does not use it internally.

    TileDepth 32998 R/W tile/strip calculations

    The Matteing and DataType tags have been obsoleted by the 6.0 ExtraSamples and SampleFormat tags. Consult the documentation on the ExtraSamples tag and Associated Alpha for elaboration. Note however that if you use Associated Alpha, you are expected to save data that is pre-multipled by Alpha. If this means nothing to you, check out Porter & Duff's paper in the '84 SIGGRAPH proceedings: "Compositing Digital Images".

    The ImageDepth tag is a non-standard, but registered tag that specifies the Z-dimension of volumetric data. The combination of ImageWidth, ImageLength, and ImageDepth, defines a 3D volume of pixels that are further specified by BitsPerSample and SamplesPerPixel. The TileDepth tag (also non-standard, but registered) can be used to specified a subvolume "tiling" of a volume of data.

    The Colorimetry, and CMYK tags are additions that appear in TIFF 6.0. Consult the TIFF 6.0 specification included in the doc directory and online.

    The JPEG-related tag is specified in TIFF Technical Note #2 which defines a revised JPEG-in-TIFF scheme (revised over that appendix that was part of the TIFF 6.0 specification).

    TIFF Test Images

    Test images are available for most formats supported by the library. Most of the images included in the test kit are also part of this documentation (albeit in TIFF rather than GIF or JFIF). The images are kept in a separate archive that should be located in the same directory as this software.

    The latest archive of test images is located at ftp://ftp.remotesensing.org/pub/libtiff/pics-3.8.0.tar.gz

    There are two other good sources for TIFF test images: the contributed software contrib/dbs includes several programs that generate test images suitable for debugging, and the tiffcp program can be used to generate a variety of images with different storage characteristics.

    This document describes the changes made to the software between the previous and current versions (see above). If you don't find something listed here, then it was not done in this timeframe, or it was not considered important enough to be mentioned. The following information is located here:

    MAJOR CHANGES:
    • New tiffcrop utility contributed by Richard Nolde. tiffcrop does the same as tiffcp, but also can crop, extract, rotate and mirror images.
    • tif_jbig.c: Added support for JBIG compression scheme (34661 code), contributed by Lee Howard.
    • Totally new implementation of OJPEG module from Joris Van Damme. No need to patch libjpeg anymore. Many OJPEG files should be supported now that was not supported previously.

    CHANGES IN THE SOFTWARE CONFIGURATION:
    • tif_config.wince.h, tiffconf.wince.h, tif_wince.c: WinCE-specific compatibility stuff from Mateusz Loskot.
    • Rename config.h.vc and tif_config.h.vc to config.vc.h and tif_config.vc.h for easier identification by folks using an IDE.
    • configure, configure.ac: OJPEG support enabled by default (i.e., whe the conformant JPEG support enabled).
    • README.vms, Makefile.am, configure.com, libtiff/{Makefile.am, tif_config.h-vms, tif_stream.cxx, tif_vms.c, tiffconf.h-vms}: Added support for OpenVMS by Alexey Chupahin.
    • nmake.opt: use /EHsc for VS2005 compatibility. Also define _CRT_SECURE_NO_DEPRECATE to avoid noise on VS2005.

    CHANGES IN LIBTIFF:
    • tif_dirinfo.c (_TIFFFindFieldInfo): Don't attempt to bsearch() on a NULL fieldinfo list. (_TIFFFindFieldInfoByName): Don't attempt to lfind() on a NULL fieldinfo list.
    • tif_jpeg.c: Changed JPEGInitializeLibJPEG() so that it will convert from decompressor to compressor or compress to decompress if required by the force arguments. This works around a problem in where the JPEGFixupTestSubsampling() may cause a decompressor to be setup on a directory when later a compressor is required with the force flag set. Occurs with the addtiffo program for instance.
    • tif_dirwrite.c: Fixed swapping of byte arrays stored in-place in tag offsets as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1363
    • tif_getimage.c: workaround for 'Fractional scanline' error reading OJPEG images with rowsperstrip that is not a multiple of vertical subsampling factor. This bug is mentioned in http://bugzilla.remotesensing.org/show_bug.cgi?id=1390 and http://www.asmail.be/msg0054766825.html
    • tif_dirread.c: Added special function to handle SubjectDistance EXIF tag as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1362
    • tif_dirread.c, tif_read.c: Type of the byte counters changed from tsize_t to uint32 to be able to work with data arrays larger than 2GB. Fixes bug http://bugzilla.remotesensing.org/show_bug.cgi?id=89 Idea submitted by Matt Hancher.
    • tif_dir.c: Workaround for incorrect TIFFs with ExtraSamples == 999 produced by Corel Draw. As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1490
    • tif_write.c: TIFFAppendToStrip() - clear sorted flag if we move a strip. http://bugzilla.remotesensing.org/show_bug.cgi?id=1359
    • tif_fax3.c: Save the state of printdir codec dependent method.
    • tif_jpeg.c: Save the state of printdir codec dependent method as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1273
    • tif_win32.c: Fixed problem with offset value manipulation as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1322
    • tif_fax3.c, tif_next.c, tif_pixarlog.c: Fixed multiple vulnerabilities, as per Gentoo bug (): http://bugs.gentoo.org/show_bug.cgi?id=142383
    • tif_lzw.c, tif_zip.c: Fixed problems with mixing encoding and decoding on the same read-write TIFF handle. The LZW code can now maintain encode and decode state at the same time. The ZIP code will switch back and forth as needed. http://bugzilla.remotesensing.org/show_bug.cgi?id=757
    • tif_msdos.c: Avoid handle leak for failed opens. c/o Thierry Pierron
    • tif_dirwrite.c: take care not to flush out buffer of strip/tile data in _TIFFWriteDirectory if TIFF_BEENWRITING not set. Relates to bug report by Peng Gao with black strip at bottom of images.
    • tif_dirwrite.c: make sure to use uint32 for wordcount in TIFFWriteNormanTag if writecount is VARIABLE2 for ASCII fields. It already seems to have been done for other field types. Needed for "tiffset" on files with geotiff ascii text.
    • tif_dirinfo.c: Added missed EXIF tag ColorSpace (40961).
    • tif_dirread.c: Move IFD fetching code in the separate function TIFFFetchDirectory() avoiding code duplication in TIFFReadDirectory() and TIFFReadCustomDirectory().
    • tif_readdir.c: Added case in EstimateStripByteCounts() for tiled files. Modified TIFFReadDirectory() to not invoke EstimateStripByteCounts() for case where entry 0 and 1 are unequal but one of them is zero. http://bugzilla.remotesensing.org/show_bug.cgi?id=1204
    • tif_open.c, tif_dirread.c, tiffiop.h: Move IFD looping checking code in the separate function TIFFCheckDirOffset().
    • tif_aux.c: Added _TIFFCheckRealloc() function.
    • tif_fax3.c: Fixed problems in fax decoder as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=1194

    • tif_getimage.c: Added support for planarconfig separate non-subsampled YCbCr (i.e. separate YCbCr with subsampling [1,1]).
    • tif_getimage.c: Revision of all RGB(A) put routines:
      • Conversion of unassociated alpha to associated alpha now done with more performant LUT, and calculation more correct.
      • Conversion of 16bit data to 8bit data now done with more performant LUT, and calculation more correct
      • Bugfix of handling of 16bit RGB with unassociated alpha
    • tif_ojpeg.c: totally new implementation
    • tif_getimage.c: removed TIFFTAG_JPEGCOLORMODE handling of OJPEG images in favor of tif_getimage.c native handling of YCbCr and desubsampling.
    • tif_jpeg.c: JPEGVSetField() so that altering the photometric interpretation causes the "upsampled" flag to be recomputed. Fixes peculiar bug where photometric flag had to be set before jpegcolormode flag.

    CHANGES IN THE TOOLS:

    CHANGES IN THE CONTRIB AREA:
    • contrib/addtiffo/tif_overview.c: Fix problems with odd sized output blocks in TIFF_DownSample_Subsampled() (bug 1542).
    • contrib/dbs/xtiff/xtiff.c: Make xtiff utility compilable. Though it is still far from the state of being working and useful.

    Building the Software Distribution


    This chapter contains step-by-step instructions on how to configure and build the TIFF software distribution. The software is most easily built on a UNIX system, but with a little bit of work it can easily be built and used on other non-UNIX platforms.

    Building on a UNIX System

    To build the software on a UNIX system you need to first run the configure shell script that is located in the top level of the source directory. This script probes the target system for necessary tools and functions and constructs a build environment in which the software may be compiled. Once configuration is done, you simply run make (or gmake) to build the software and then make install to do the installation; for example: 
    hyla% cd ./tiff-4.0.0
hyla% ./configure
    ...lots of messages...
hyla% make
    ...lots of messages...
hyla% make check
    ...lots of messages...
hyla# make install
    Supplied makefiles are dependent on a make utility and a C (and optionally a C++ compiler), so you will need these tools.

    In general, the software is designed such that the following should be ``make-able'' in each directory:

    make [all]      build stuff
make check      run the test suite
make install    build&install stuff
make clean      remove .o files, executables and cruft
make distclean  remove everything, that can be recreated
    Note that after running "make distclean" the configure script must be run again to create the Makefiles and other make-related files.

    Build Trees

    There are two schemes for configuring and building the software. If you intend to build the software for only one target system, you can configure the software so that it is built in the same directories as the source code. 
    hyla% gzip -dc tiff-4.0.0.tar.gz | tar -xf -
hyla% cd ./tiff-4.0.0
hyla% ./configure
hyla% make
hyla% make check
hyla% make install

    Otherwise, you can configure a build tree that is parallel to the source tree hierarchy (or in some completely different place) but which contains only configured files and files created during the build procedure.

    hyla% gzip -dc tiff-4.0.0.tar.gz | tar -xf -
hyla% mkdir tiff-4.0.0-build
hyla% cd ./tiff-4.0.0-build
hyla% ../tiff-4.0.0/configure
hyla% make
hyla% make check
hyla% make install
    This second scheme is useful for:
    • building multiple targets from a single source tree
    • building from a read-only source tree (e.g. if you receive the distribution on CD-ROM)
    • sharing the source files via a network, but building on multiple systems

    Configuration Options

    The configuration process is critical to the proper compilation, installation, and operation of the software. The configure script runs a series of tests to decide whether or not the target system supports required functionality and, if it does not, whether it can emulate or workaround the missing functions. This procedure is fairly complicated and, due to the nonstandard nature of most UNIX systems, prone to error. The first time that you configure the software for use you should check the output from the configure script and look for anything that does not make sense for your system.

    A second function of the configure script is to set the default configuration parameters for the software. Of particular note are the directories where the software is to be installed. By default the software is installed in the /usr/local hierarchy. To change this behaviour the appropriate parameters can be specified on the command line to configure. Run ./configure --help to get a full list of possible options. Standard installation related options are shown below.

    
Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [/usr/local]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/tiff]
  --htmldir=DIR           html documentation [DOCDIR]

Program names:
  --program-prefix=PREFIX            prepend PREFIX to installed program names
  --program-suffix=SUFFIX            append SUFFIX to installed program names
  --program-transform-name=PROGRAM   run sed PROGRAM on installed program names

    Configuring Optional Packages/Support

    The TIFF software comes with several packages that are installed only as needed, or only if specifically configured at the time the configure script is run. Packages can be configured via the configure script commandline parameters.
    Static/Shared Objects Support
    --enable-shared[=PKGS]    build shared libraries [default=yes]
    --enable-static[=PKGS]    build static libraries [default=yes]

    These options control whether or not to configure the software to build a shared and static binaries for the TIFF library. Use of shared libraries can significantly reduce the disk space needed for users of the TIFF software. If shared libarries are not used then the code is statically linked into each application that uses it. By default both types of binaries is configured.

    --enable-rpath             Enable runtime linker paths (-R libtool option)

    Add library directories (see other options below) to the TIFF library run-time linker path.

    --enable-ld-version-script  Enable linker version script (default is disabled)

    Add shared library symbol versioning on ELF-based systems (e.g. Linux and FreeBSD) which use the GNU linker. This is needed if several major versions of libtiff might be loaded at once into the same program.

    JPEG Support
    --disable-jpeg    disable IJG JPEG library usage (required for JPEG compression, enabled by default) --with-jpeg-include-dir=DIR    location of IJG JPEG library headers --with-jpeg-lib-dir=DIR    location of IJG JPEG library binary)
    The JPEG package enables support for the handling of TIFF images with JPEG-encoded data. Support for JPEG-encoded data requires the Independent JPEG Group (IJG) libjpeg distribution; this software is available at http://www.ijg.org/. configure script automatically tries to search for a working IJG JPEG installation. If it fails to find library, JPEG support will be automatically disabled.If you want specify the exact paths to library binary and headers, use above switches for that.
    ZIP Support
    The ZIP support enables support for the handling of TIFF images with deflate-encoded data. Support for deflate-encoded data requires the freely available zlib distribution written by Jean-loup Gailly and Mark Adler; this software is available at http://www.zlib.org/. If ZIP support is enabled the DIRS_LIBINC and DIR_GZLIB parameters should also be set (see below). By default this package is not configured.

    Building the Software under Windows 95/98/NT/2000 with MS VC++

    With Microsoft Visual C++ installed, and properly configured for commandline use (you will likely need to source VCVARS32.BAT in AUTOEXEC.bAT or somewhere similar) you should be able to use the provided makefile.vc.

    The source package is delivered using Unix line termination conventions, which work with MSVC but do not work with Windows 'notepad'. If you use unzip from the Info-Zip package, you can extract the files using Windows normal line termination conventions with a command similar to:

      unzip -aa -a tiff-4.0.0.zip

    By default libtiff expects that a pre-built zlib and jpeg library are provided by the user. If this is not the case, then you may edit libtiff\tiffconf.h using a text editor (e.g. notepad) and comment out the entries for JPEG_SUPPORT, PIXARLOG_SUPPORT, and ZIP_SUPPORT. Ignore the comment at the top of the file which says that it has no influence on the build, because the statement is not true for Windows. However, by taking this approach, libtiff will not be able to open some TIFF files.

    To build using the provided makefile.vc you may use:

      C:\tiff-4.0.0> nmake /f makefile.vc clean
  C:\tiff-4.0.0> nmake /f makefile.vc

    or (the hard way)

  C:\tiff-4.0.0> cd port
  C:\tiff-4.0.0\port> nmake /f makefile.vc clean
  C:\tiff-4.0.0\port> nmake /f makefile.vc
  C:\tiff-4.0.0> cd ../libtiff
  C:\tiff-4.0.0\libtiff> nmake /f makefile.vc clean
  C:\tiff-4.0.0\libtiff> nmake /f makefile.vc
  C:\tiff-4.0.0\libtiff> cd ..\tools
  C:\tiff-4.0.0\tools> nmake /f makefile.vc clean
  C:\tiff-4.0.0\tools> nmake /f makefile.vc

    This will build the library file libtiff\libtiff\libtiff.lib. This can be used in Win32 programs. You may want to adjust the build options before start compiling. All parameters contained in the nmake.opt file.This is a plain text file you can open with your favorite text editor.

    The makefile also builds a DLL (libtiff.dll) with an associated import library (libtiff_i.lib). Any builds using libtiff will need to include the LIBTIFF\LIBTIFF directory in the include path.

    The libtiff\tools\makefile.vc should build .exe's for all the standard TIFF tool programs.

    Building the Software on a VMS System

    The VMS port was done by Karsten Spang (krs@kampsax.dk), who also "sort of" maintains it. The VMS specific files are not in the main directories. Instead they are placed under [.CONTRIB.VMS...] in the distribution tree. Installation: It is assumed that you have unpacked the tar file into a VMS directory tree, in this text called DISK:[TIFF].
    1. Move the VMS specific files to their proper directories. 
      $ SET DEFAULT DISK:[TIFF.CONTRIB.VMS]
$ RENAME [.LIBTIFF]*.* [-.-.LIBTIFF]
$ RENAME [.TOOLS]*.* [-.-.TOOLS]
    2. Compile the library. 
      $ SET DEFAULT DISK:[TIFF.LIBTIFF]
$ @MAKEVMS
    3. Compile the tools. 
      $ SET DEFAULT DISK:[TIFF.TOOLS]
$ @MAKEVMS
    4. Define the programs. 
      $ DEFINE TIFFSHR DISK:[TIFF.LIBTIFF]TIFFSHR
$ FAX2PS    :==$DISK:[TIFF.TOOLS]FAX2PS
$ FAX2TIFF  :==$DISK:[TIFF.TOOLS]FAX2TIFF

    You will want to add these lines to your LOGIN.COM file, after changing the name of the directory that you have used on your machine.

    This release has been tested on OpenVMS/VAX 5.5-2, using VAX C 3.2. A previous release was tested under OpenVMS/AXP ?.? using DEC C ?.?, it is believed that this release as well works on AXP. The code contains some GNU C specific things. This does *not* imply, however, that the VAX/GCC configuration has been tested, *it has not*.

    The command procedures (MAKEVMS.COM) for building the library and tools, is believed to choose the correct options for the VAX and AXP cases automatically.

    On the AXP, IEEE floating point is used by default. If you want VAX floating point, remove the /FLOAT=IEEE_FLOAT qualifier, and change HAVE_IEEEFP=1 to HAVE_IEEEFP=0 in the MAKEVMS.COM files in both the libtiff and tools directories.

    Compiling your own program on a VMS system:

    When compiling a source file in which you "#include <tiffio.h>", use the following command 
        $ CC/INCLUDE=DISK:[TIFF.LIBTIFF]
    This ensures that the header file is found. On the AXP, also add /FLOAT=IEEE_FLOAT (if used when building the library).

    Linking your own program to the TIFF library on a VMS system:

    You can link to the library in two ways: Either using the shareable library, or using the object library. On the VAX these possibilities are:
    1. Using the shareable TIFF library. 
      $ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS,SYS$INPUT:/OPTIONS
    SYS$SHARE:VAXCRTL/SHAREABLE
    2. Using the TIFF object library. 
      $ LINK MY_PROGRAM, -
    DISK:[TIFF.LIBTIFF]TIFF/LIBRARY/INCLUDE=(TIF_FAX3SM,TIF_CODEC), -
    SYS$INPUT:/OPTIONS
    SYS$SHARE:VAXCRTL/SHAREABLE
    On AXP (and possibly also using DEC C on VAX) the corresponding commands are
    1. Using the shareable TIFF library. 
      $ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS
    2. Using the TIFF object library. 
      $ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/LIBRARY
    Method 1 uses the shortest link time and smallest .EXE files, but it requires that TIFFSHR is defined as above at link time and at run time. Using the compilation procedure above, the tools are linked in this way.

    Method 2 gives somewhat longer link time and larger .EXE files, but does not require TIFFSHR to be defined. This method is recommended if you want to run your program on another machine, and for some reason don't want to have the library on that machine. If you plan to have more than one program (including the tools) on the machine, it is recommended that you copy the library to the other machine and use method 1.

    Building the Software on Other Systems

    This section contains information that might be useful if you are working on a non-UNIX system that is not directly supported. All library-related files described below are located in the libtiff directory.

    The library requires two files that are generated on-the-fly. The file tif_fax3sm.c has the state tables for the Group 3 and Group 4 decoders. This file is generated by the mkg3states program on a UNIX system; for example,

    
cd libtiff
cc -o mkg3states mkg3states.c
rm -f tif_fax3sm.c
./mkg3states -c const tif_fax3sm.c
    The -c option can be used to control whether or not the resutling tables are generated with a const declaration. The -s option can be used to specify a C storage class for the table declarations. The -b option can be used to force data values to be explicitly bracketed with ``{}'' (apparently needed for some MS-Windows compilers); otherwise the structures are emitted in as compact a format as possible. Consult the source code for this program if you have questions.

    The second file required to build the library, version.h, contains the version information returned by the TIFFGetVersion routine. This file is built on most systems using the mkversion program and the contents of the VERSION and tiff.alpha files; for example,

    cd libtiff
cc -o mkversion mkversion.c
rm -f version.h
./mkversion -v ../VERSION -a ../dist/tiff.alpha version.h

    Otherwise, when building the library on a non-UNIX system be sure to consult the files tiffcomp.h and tiffconf.h. The former contains system compatibility definitions while the latter is provided so that the software configuration can be controlled on systems that do not support the make facility for building the software.

    Systems without a 32-bit compiler may not be able to handle some of the codecs in the library; especially the Group 3 and 4 decoder. If you encounter problems try disabling support for a particular codec; consult the documentation.

    Programs in the tools directory are written to assume an ANSI C compilation environment. There may be a few POSIX'isms as well. The code in the port directory is provided to emulate routines that may be missing on some systems. On UNIX systems the configure script automatically figures out which routines are not present on a system and enables the use of the equivalent emulation routines from the port directory. It may be necessary to manually do this work on a non-UNIX system.

    Checking out the Software

    Assuming you have working versions of tiffgt and tiffsv, you can just use them to view any of the sample images available for testing (see the section on obtaining the test images). Otherwise, you can do a cursory check of the library with the tiffcp and tiffcmp programs. For example,

    tiffcp -lzw cramps.tif x.tif
tiffcmp cramps.tif x.tif

    (tiffcmp should be silent if the files compare correctly).

    DRAFT TIFF Technical Note #2				17-Mar-95
============================

This Technical Note describes serious problems that have been found in
TIFF 6.0's design for embedding JPEG-compressed data in TIFF (Section 22
of the TIFF 6.0 spec of 3 June 1992).  A replacement TIFF/JPEG
specification is given.  Some corrections to Section 21 are also given.

To permit TIFF implementations to continue to read existing files, the 6.0
JPEG fields and tag values will remain reserved indefinitely.  However,
TIFF writers are strongly discouraged from using the 6.0 JPEG design.  It
is expected that the next full release of the TIFF specification will not
describe the old design at all, except to note that certain tag numbers
are reserved.  The existing Section 22 will be replaced by the
specification text given in the second part of this Tech Note.


Problems in TIFF 6.0 JPEG
=========================

Abandoning a published spec is not a step to be taken lightly.  This
section summarizes the reasons that have forced this decision.
TIFF 6.0's JPEG design suffers from design errors and limitations,
ambiguities, and unnecessary complexity.


Design errors and limitations
-----------------------------

The fundamental design error in the existing Section 22 is that JPEG's
various tables and parameters are broken out as separate fields which the
TIFF control logic must manage.  This is bad software engineering: that
information should be treated as private to the JPEG codec
(compressor/decompressor).  Worse, the fields themselves are specified
without sufficient thought for future extension and without regard to
well-established TIFF conventions.  Here are some of the significant
problems:

* The JPEGxxTable fields do not store the table data directly in the
IFD/field structure; rather, the fields hold pointers to information
elsewhere in the file.  This requires special-purpose code to be added to
*every* TIFF-manipulating application, whether it needs to decode JPEG
image data or not.  Even a trivial TIFF editor, for example a program to
add an ImageDescription field to a TIFF file, must be explicitly aware of
the internal structure of the JPEG-related tables, or else it will probably
break the file.  Every other auxiliary field in the TIFF spec contains
data, not pointers, and can be copied or relocated by standard code that
doesn't know anything about the particular field.  This is a crucial
property of the TIFF format that must not be given up.

* To manipulate these fields, the TIFF control logic is required to know a
great deal about JPEG details, for example such arcana as how to compute
the length of a Huffman code table --- the length is not supplied in the
field structure and can only be found by inspecting the table contents.
This is again a violation of good software practice.  Moreover, it will
prevent easy adoption of future JPEG extensions that might change these
low-level details.

* The design neglects the fact that baseline JPEG codecs support only two
sets of Huffman tables: it specifies a separate table for each color
component.  This implies that encoders must waste space (by storing
duplicate Huffman tables) or else violate the well-founded TIFF convention
that prohibits duplicate pointers.  Furthermore, baseline decoders must
test to find out which tables are identical, a waste of time and code
space.

* The JPEGInterchangeFormat field also violates TIFF's proscription against
duplicate pointers: the normal strip/tile pointers are expected to point
into the larger data area pointed to by JPEGInterchangeFormat.  All TIFF
editing applications must be specifically aware of this relationship, since
they must maintain it or else delete the JPEGInterchangeFormat field.  The
JPEGxxTables fields are also likely to point into the JPEGInterchangeFormat
area, creating additional pointer relationships that must be maintained.

* The JPEGQTables field is fixed at a byte per table entry; there is no
way to support 16-bit quantization values.  This is a serious impediment
to extending TIFF to use 12-bit JPEG.

* The 6.0 design cannot support using different quantization tables in
different strips/tiles of an image (so as to encode some areas at higher
quality than others).  Furthermore, since quantization tables are tied
one-for-one to color components, the design cannot support table switching
options that are likely to be added in future JPEG revisions.


Ambiguities
-----------

Several incompatible interpretations are possible for 6.0's treatment of
JPEG restart markers:

  * It is unclear whether restart markers must be omitted at TIFF segment
    (strip/tile) boundaries, or whether they are optional.

  * It is unclear whether the segment size is required to be chosen as
    a multiple of the specified restart interval (if any); perhaps the
    JPEG codec is supposed to be reset at each segment boundary as if
    there were a restart marker there, even if the boundary does not fall
    at a multiple of the nominal restart interval.

  * The spec fails to address the question of restart marker numbering:
    do the numbers begin again within each segment, or not?

That last point is particularly nasty.  If we make numbering begin again
within each segment, we give up the ability to impose a TIFF strip/tile
structure on an existing JPEG datastream with restarts (which was clearly a
goal of Section 22's authors).  But the other choice interferes with random
access to the image segments: a reader must compute the first restart
number to be expected within a segment, and must have a way to reset its
JPEG decoder to expect a nonzero restart number first.  This may not even
be possible with some JPEG chips.

The tile height restriction found on page 104 contradicts Section 15's
general description of tiles.  For an image that is not vertically
downsampled, page 104 specifies a tile height of one MCU or 8 pixels; but
Section 15 requires tiles to be a multiple of 16 pixels high.

This Tech Note does not attempt to resolve these ambiguities, so
implementations that follow the 6.0 design should be aware that
inter-application compatibility problems are likely to arise.


Unnecessary complexity
----------------------

The 6.0 design creates problems for implementations that need to keep the
JPEG codec separate from the TIFF control logic --- for example, consider
using a JPEG chip that was not designed specifically for TIFF.  JPEG codecs
generally want to produce or consume a standard ISO JPEG datastream, not
just raw compressed data.  (If they were to handle raw data, a separate
out-of-band mechanism would be needed to load tables into the codec.)
With such a codec, the TIFF control logic must parse JPEG markers emitted
by the codec to create the TIFF table fields (when writing) or synthesize
JPEG markers from the TIFF fields to feed the codec (when reading).  This
means that the control logic must know a great deal more about JPEG details
than we would like.  The parsing and reconstruction of the markers also
represents a fair amount of unnecessary work.

Quite a few implementors have proposed writing "TIFF/JPEG" files in which
a standard JPEG datastream is simply dumped into the file and pointed to
by JPEGInterchangeFormat.  To avoid parsing the JPEG datastream, they
suggest not writing the JPEG auxiliary fields (JPEGxxTables etc) nor even
the basic TIFF strip/tile data pointers.  This approach is incompatible
with implementations that handle the full TIFF 6.0 JPEG design, since they
will expect to find strip/tile pointers and auxiliary fields.  Indeed this
is arguably not TIFF at all, since *all* TIFF-reading applications expect
to find strip or tile pointers.  A subset implementation that is not
upward-compatible with the full spec is clearly unacceptable.  However,
the frequency with which this idea has come up makes it clear that
implementors find the existing Section 22 too complex.


Overview of the solution
========================

To solve these problems, we adopt a new design for embedding
JPEG-compressed data in TIFF files.  The new design uses only complete,
uninterpreted ISO JPEG datastreams, so it should be much more forgiving of
extensions to the ISO standard.  It should also be far easier to implement
using unmodified JPEG codecs.

To reduce overhead in multi-segment TIFF files, we allow JPEG overhead
tables to be stored just once in a JPEGTables auxiliary field.  This
feature does not violate the integrity of the JPEG datastreams, because it
uses the notions of "tables-only datastreams" and "abbreviated image
datastreams" as defined by the ISO standard.

To prevent confusion with the old design, the new design is given a new
Compression tag value, Compression=7.  Readers that need to handle
existing 6.0 JPEG files may read both old and new files, using whatever
interpretation of the 6.0 spec they did before.  Compression tag value 6
and the field tag numbers defined by 6.0 section 22 will remain reserved
indefinitely, even though detailed descriptions of them will be dropped
from future editions of the TIFF specification.


Replacement TIFF/JPEG specification
===================================

[This section of the Tech Note is expected to replace Section 22 in the
next release of the TIFF specification.]

This section describes TIFF compression scheme 7, a high-performance
compression method for continuous-tone images.

Introduction
------------

This TIFF compression method uses the international standard for image
compression ISO/IEC 10918-1, usually known as "JPEG" (after the original
name of the standards committee, Joint Photographic Experts Group).  JPEG
is a joint ISO/CCITT standard for compression of continuous-tone images.

The JPEG committee decided that because of the broad scope of the standard,
no one algorithmic procedure was able to satisfy the requirements of all
applications.  Instead, the JPEG standard became a "toolkit" of multiple
algorithms and optional capabilities.  Individual applications may select
a subset of the JPEG standard that meets their requirements.

The most important distinction among the JPEG processes is between lossy
and lossless compression.  Lossy compression methods provide high
compression but allow only approximate reconstruction of the original
image.  JPEG's lossy processes allow the encoder to trade off compressed
file size against reconstruction fidelity over a wide range.  Typically,
10:1 or more compression of full-color data can be obtained while keeping
the reconstructed image visually indistinguishable from the original.  Much
higher compression ratios are possible if a low-quality reconstructed image
is acceptable.  Lossless compression provides exact reconstruction of the
source data, but the achievable compression ratio is much lower than for
the lossy processes; JPEG's rather simple lossless process typically
achieves around 2:1 compression of full-color data.

The most widely implemented JPEG subset is the "baseline" JPEG process.
This provides lossy compression of 8-bit-per-channel data.  Optional
extensions include 12-bit-per-channel data, arithmetic entropy coding for
better compression, and progressive/hierarchical representations.  The
lossless process is an independent algorithm that has little in
common with the lossy processes.

It should be noted that the optional arithmetic-coding extension is subject
to several US and Japanese patents.  To avoid patent problems, use of
arithmetic coding processes in TIFF files intended for inter-application
interchange is discouraged.

All of the JPEG processes are useful only for "continuous tone" data,
in which the difference between adjacent pixel values is usually small.
Low-bit-depth source data is not appropriate for JPEG compression, nor
are palette-color images good candidates.  The JPEG processes work well
on grayscale and full-color data.

Describing the JPEG compression algorithms in sufficient detail to permit
implementation would require more space than we have here.  Instead, we
refer the reader to the References section.


What data is being compressed?
------------------------------

In lossy JPEG compression, it is customary to convert color source data
to YCbCr and then downsample it before JPEG compression.  This gives
2:1 data compression with hardly any visible image degradation, and it
permits additional space savings within the JPEG compression step proper.
However, these steps are not considered part of the ISO JPEG standard.
The ISO standard is "color blind": it accepts data in any color space.

For TIFF purposes, the JPEG compression tag is considered to represent the
ISO JPEG compression standard only.  The ISO standard is applied to the
same data that would be stored in the TIFF file if no compression were
used.  Therefore, if color conversion or downsampling are used, they must
be reflected in the regular TIFF fields; these steps are not considered to
be implicit in the JPEG compression tag value.  PhotometricInterpretation
and related fields shall describe the color space actually stored in the
file.  With the TIFF 6.0 field definitions, downsampling is permissible
only for YCbCr data, and it must correspond to the YCbCrSubSampling field.
(Note that the default value for this field is not 1,1; so the default for
YCbCr is to apply downsampling!)  It is likely that future versions of TIFF
will provide additional PhotometricInterpretation values and a more general
way of defining subsampling, so as to allow more flexibility in
JPEG-compressed files.  But that issue is not addressed in this Tech Note.

Implementors should note that many popular JPEG codecs
(compressor/decompressors) provide automatic color conversion and
downsampling, so that the application may supply full-size RGB data which
is nonetheless converted to downsampled YCbCr.  This is an implementation
convenience which does not excuse the TIFF control layer from its
responsibility to know what is really going on.  The
PhotometricInterpretation and subsampling fields written to the file must
describe what is actually in the file.

A JPEG-compressed TIFF file will typically have PhotometricInterpretation =
YCbCr and YCbCrSubSampling = [2,1] or [2,2], unless the source data was
grayscale or CMYK.


Basic representation of JPEG-compressed images
----------------------------------------------

JPEG compression works in either strip-based or tile-based TIFF files.
Rather than repeating "strip or tile" constantly, we will use the term
"segment" to mean either a strip or a tile.

When the Compression field has the value 7, each image segment contains
a complete JPEG datastream which is valid according to the ISO JPEG
standard (ISO/IEC 10918-1).  Any sequential JPEG process can be used,
including lossless JPEG, but progressive and hierarchical processes are not
supported.  Since JPEG is useful only for continuous-tone images, the
PhotometricInterpretation of the image shall not be 3 (palette color) nor
4 (transparency mask).  The bit depth of the data is also restricted as
specified below.

Each image segment in a JPEG-compressed TIFF file shall contain a valid
JPEG datastream according to the ISO JPEG standard's rules for
interchange-format or abbreviated-image-format data.  The datastream shall
contain a single JPEG frame storing that segment of the image.  The
required JPEG markers within a segment are:
	SOI	(must appear at very beginning of segment)
	SOFn
	SOS	(one for each scan, if there is more than one scan)
	EOI	(must appear at very end of segment)
The actual compressed data follows SOS; it may contain RSTn markers if DRI
is used.

Additional JPEG "tables and miscellaneous" markers may appear between SOI
and SOFn, between SOFn and SOS, and before each subsequent SOS if there is
more than one scan.  These markers include:
	DQT
	DHT
	DAC	(not to appear unless arithmetic coding is used)
	DRI
	APPn	(shall be ignored by TIFF readers)
	COM	(shall be ignored by TIFF readers)
DNL markers shall not be used in TIFF files.  Readers should abort if any
other marker type is found, especially the JPEG reserved markers;
occurrence of such a marker is likely to indicate a JPEG extension.

The tables/miscellaneous markers may appear in any order.  Readers are
cautioned that although the SOFn marker refers to DQT tables, JPEG does not
require those tables to precede the SOFn, only the SOS.  Missing-table
checks should be made when SOS is reached.

If no JPEGTables field is used, then each image segment shall be a complete
JPEG interchange datastream.  Each segment must define all the tables it
references.  To allow readers to decode segments in any order, no segment
may rely on tables being carried over from a previous segment.

When a JPEGTables field is used, image segments may omit tables that have
been specified in the JPEGTables field.  Further details appear below.

The SOFn marker shall be of type SOF0 for strict baseline JPEG data, of
type SOF1 for non-baseline lossy JPEG data, or of type SOF3 for lossless
JPEG data.  (SOF9 or SOF11 would be used for arithmetic coding.)  All
segments of a JPEG-compressed TIFF image shall use the same JPEG
compression process, in particular the same SOFn type.

The data precision field of the SOFn marker shall agree with the TIFF
BitsPerSample field.  (Note that when PlanarConfiguration=1, this implies
that all components must have the same BitsPerSample value; when
PlanarConfiguration=2, different components could have different bit
depths.)  For SOF0 only precision 8 is permitted; for SOF1, precision 8 or
12 is permitted; for SOF3, precisions 2 to 16 are permitted.

The image dimensions given in the SOFn marker shall agree with the logical
dimensions of that particular strip or tile.  For strip images, the SOFn
image width shall equal ImageWidth and the height shall equal RowsPerStrip,
except in the last strip; its SOFn height shall equal the number of rows
remaining in the ImageLength.  (In other words, no padding data is counted
in the SOFn dimensions.)  For tile images, each SOFn shall have width
TileWidth and height TileHeight; adding and removing any padding needed in
the edge tiles is the concern of some higher level of the TIFF software.
(The dimensional rules are slightly different when PlanarConfiguration=2,
as described below.)

The ISO JPEG standard only permits images up to 65535 pixels in width or
height, due to 2-byte fields in the SOFn markers.  In TIFF, this limits
the size of an individual JPEG-compressed strip or tile, but the total
image size can be greater.

The number of components in the JPEG datastream shall equal SamplesPerPixel
for PlanarConfiguration=1, and shall be 1 for PlanarConfiguration=2.  The
components shall be stored in the same order as they are described at the
TIFF field level.  (This applies both to their order in the SOFn marker,
and to the order in which they are scanned if multiple JPEG scans are
used.)  The component ID bytes are arbitrary so long as each component
within an image segment is given a distinct ID.  To avoid any possible
confusion, we require that all segments of a TIFF image use the same ID
code for a given component.

In PlanarConfiguration 1, the sampling factors given in SOFn markers shall
agree with the sampling factors defined by the related TIFF fields (or with
the default values that are specified in the absence of those fields).

When DCT-based JPEG is used in a strip TIFF file, RowsPerStrip is required
to be a multiple of 8 times the largest vertical sampling factor, i.e., a
multiple of the height of an interleaved MCU.  (For simplicity of
specification, we require this even if the data is not actually
interleaved.)  For example, if YCbCrSubSampling = [2,2] then RowsPerStrip
must be a multiple of 16.  An exception to this rule is made for
single-strip images (RowsPerStrip >= ImageLength): the exact value of
RowsPerStrip is unimportant in that case.  This rule ensures that no data
padding is needed at the bottom of a strip, except perhaps the last strip.
Any padding required at the right edge of the image, or at the bottom of
the last strip, is expected to occur internally to the JPEG codec.

When DCT-based JPEG is used in a tiled TIFF file, TileLength is required
to be a multiple of 8 times the largest vertical sampling factor, i.e.,
a multiple of the height of an interleaved MCU; and TileWidth is required
to be a multiple of 8 times the largest horizontal sampling factor, i.e.,
a multiple of the width of an interleaved MCU.  (For simplicity of
specification, we require this even if the data is not actually
interleaved.)  All edge padding required will therefore occur in the course
of normal TIFF tile padding; it is not special to JPEG.

Lossless JPEG does not impose these constraints on strip and tile sizes,
since it is not DCT-based.

Note that within JPEG datastreams, multibyte values appear in the MSB-first
order specified by the JPEG standard, regardless of the byte ordering of
the surrounding TIFF file.


JPEGTables field
----------------

The only auxiliary TIFF field added for Compression=7 is the optional
JPEGTables field.  The purpose of JPEGTables is to predefine JPEG
quantization and/or Huffman tables for subsequent use by JPEG image
segments.  When this is done, these rather bulky tables need not be
duplicated in each segment, thus saving space and processing time.
JPEGTables may be used even in a single-segment file, although there is no
space savings in that case.

JPEGTables:
	Tag = 347 (15B.H)
	Type = UNDEFINED
	N = number of bytes in tables datastream, typically a few hundred
JPEGTables provides default JPEG quantization and/or Huffman tables which
are used whenever a segment datastream does not contain its own tables, as
specified below.

Notice that the JPEGTables field is required to have type code UNDEFINED,
not type code BYTE.  This is to cue readers that expanding individual bytes
to short or long integers is not appropriate.  A TIFF reader will generally
need to store the field value as an uninterpreted byte sequence until it is
fed to the JPEG decoder.

Multibyte quantities within the tables follow the ISO JPEG convention of
MSB-first storage, regardless of the byte ordering of the surrounding TIFF
file.

When the JPEGTables field is present, it shall contain a valid JPEG
"abbreviated table specification" datastream.  This datastream shall begin
with SOI and end with EOI.  It may contain zero or more JPEG "tables and
miscellaneous" markers, namely:
	DQT
	DHT
	DAC	(not to appear unless arithmetic coding is used)
	DRI
	APPn	(shall be ignored by TIFF readers)
	COM	(shall be ignored by TIFF readers)
Since JPEG defines the SOI marker to reset the DAC and DRI state, these two
markers' values cannot be carried over into any image datastream, and thus
they are effectively no-ops in the JPEGTables field.  To avoid confusion,
it is recommended that writers not place DAC or DRI markers in JPEGTables.
However readers must properly skip over them if they appear.

When JPEGTables is present, readers shall load the table specifications
contained in JPEGTables before processing image segment datastreams.
Image segments may simply refer to these preloaded tables without defining
them.  An image segment can still define and use its own tables, subject to
the restrictions below.

An image segment may not redefine any table defined in JPEGTables.  (This
restriction is imposed to allow readers to process image segments in random
order without having to reload JPEGTables between segments.)  Therefore, use
of JPEGTables divides the available table slots into two groups: "global"
slots are defined in JPEGTables and may be used but not redefined by
segments; "local" slots are available for local definition and use in each
segment.  To permit random access, a segment may not reference any local
tables that it does not itself define.


Special considerations for PlanarConfiguration 2
------------------------------------------------

In PlanarConfiguration 2, each image segment contains data for only one
color component.  To avoid confusing the JPEG codec, we wish the segments
to look like valid single-channel (i.e., grayscale) JPEG datastreams.  This
means that different rules must be used for the SOFn parameters.

In PlanarConfiguration 2, the dimensions given in the SOFn of a subsampled
component shall be scaled down by the sampling factors compared to the SOFn
dimensions that would be used in PlanarConfiguration 1.  This is necessary
to match the actual number of samples stored in that segment, so that the
JPEG codec doesn't complain about too much or too little data.  In strip
TIFF files the computed dimensions may need to be rounded up to the next
integer; in tiled files, the restrictions on tile size make this case
impossible.

Furthermore, all SOFn sampling factors shall be given as 1.  (This is
merely to avoid confusion, since the sampling factors in a single-channel
JPEG datastream have no real effect.)

Any downsampling will need to happen externally to the JPEG codec, since
JPEG sampling factors are defined with reference to the full-precision
component.  In PlanarConfiguration 2, the JPEG codec will be working on
only one component at a time and thus will have no reference component to
downsample against.


Minimum requirements for TIFF/JPEG
----------------------------------

ISO JPEG is a large and complex standard; most implementations support only
a subset of it.  Here we define a "core" subset of TIFF/JPEG which readers
must support to claim TIFF/JPEG compatibility.  For maximum
cross-application compatibility, we recommend that writers confine
themselves to this subset unless there is very good reason to do otherwise.

Use the ISO baseline JPEG process: 8-bit data precision, Huffman coding,
with no more than 2 DC and 2 AC Huffman tables.  Note that this implies
BitsPerSample = 8 for each component.  We recommend deviating from baseline
JPEG only if 12-bit data precision or lossless coding is required.

Use no subsampling (all JPEG sampling factors = 1) for color spaces other
than YCbCr.  (This is, in fact, required with the TIFF 6.0 field
definitions, but may not be so in future revisions.)  For YCbCr, use one of
the following choices:
	YCbCrSubSampling field		JPEG sampling factors
	1,1				1h1v, 1h1v, 1h1v
	2,1				2h1v, 1h1v, 1h1v
	2,2  (default value)		2h2v, 1h1v, 1h1v
We recommend that RGB source data be converted to YCbCr for best compression
results.  Other source data colorspaces should probably be left alone.
Minimal readers need not support JPEG images with colorspaces other than
YCbCr and grayscale (PhotometricInterpretation = 6 or 1).

A minimal reader also need not support JPEG YCbCr images with nondefault
values of YCbCrCoefficients or YCbCrPositioning, nor with values of
ReferenceBlackWhite other than [0,255,128,255,128,255].  (These values
correspond to the RGB<=>YCbCr conversion specified by JFIF, which is widely
implemented in JPEG codecs.)

Writers are reminded that a ReferenceBlackWhite field *must* be included
when PhotometricInterpretation is YCbCr, because the default
ReferenceBlackWhite values are inappropriate for YCbCr.

If any subsampling is used, PlanarConfiguration=1 is preferred to avoid the
possibly-confusing requirements of PlanarConfiguration=2.  In any case,
readers are not required to support PlanarConfiguration=2.

If possible, use a single interleaved scan in each image segment.  This is
not legal JPEG if there are more than 4 SamplesPerPixel or if the sampling
factors are such that more than 10 blocks would be needed per MCU; in that
case, use a separate scan for each component.  (The recommended color
spaces and sampling factors will not run into that restriction, so a
minimal reader need not support more than one scan per segment.)

To claim TIFF/JPEG compatibility, readers shall support multiple-strip TIFF
files and the optional JPEGTables field; it is not acceptable to read only
single-datastream files.  Support for tiled TIFF files is strongly
recommended but not required.


Other recommendations for implementors
--------------------------------------

The TIFF tag Compression=7 guarantees only that the compressed data is
represented as ISO JPEG datastreams.  Since JPEG is a large and evolving
standard, readers should apply careful error checking to the JPEG markers
to ensure that the compression process is within their capabilities.  In
particular, to avoid being confused by future extensions to the JPEG
standard, it is important to abort if unknown marker codes are seen.

The point of requiring that all image segments use the same JPEG process is
to ensure that a reader need check only one segment to determine whether it
can handle the image.  For example, consider a TIFF reader that has access
to fast but restricted JPEG hardware, as well as a slower, more general
software implementation.  It is desirable to check only one image segment
to find out whether the fast hardware can be used.  Thus, writers should
try to ensure that all segments of an image look as much "alike" as
possible: there should be no variation in scan layout, use of options such
as DRI, etc.  Ideally, segments will be processed identically except
perhaps for using different local quantization or entropy-coding tables.

Writers should avoid including "noise" JPEG markers (COM and APPn markers).
Standard TIFF fields provide a better way to transport any non-image data.
Some JPEG codecs may change behavior if they see an APPn marker they
think they understand; since the TIFF spec requires these markers to be
ignored, this behavior is undesirable.

It is possible to convert an interchange-JPEG file (e.g., a JFIF file) to
TIFF simply by dropping the interchange datastream into a single strip.
(However, designers are reminded that the TIFF spec discourages huge
strips; splitting the image is somewhat more work but may give better
results.)  Conversion from TIFF to interchange JPEG is more complex.  A
strip-based TIFF/JPEG file can be converted fairly easily if all strips use
identical JPEG tables and no RSTn markers: just delete the overhead markers
and insert RSTn markers between strips.  Converting tiled images is harder,
since the data will usually not be in the right order (unless the tiles are
only one MCU high).  This can still be done losslessly, but it will require
undoing and redoing the entropy coding so that the DC coefficient
differences can be updated.

There is no default value for JPEGTables: standard TIFF files must define all
tables that they reference.  For some closed systems in which many files will
have identical tables, it might make sense to define a default JPEGTables
value to avoid actually storing the tables.  Or even better, invent a
private field selecting one of N default JPEGTables settings, so as to allow
for future expansion.  Either of these must be regarded as a private
extension that will render the files unreadable by other applications.

Changes to Section 21: YCbCr Images
===================================

[This section of the Tech Note clarifies section 21 to make clear the
interpretation of image dimensions in a subsampled image.  Furthermore,
the section is changed to allow the original image dimensions not to be
multiples of the sampling factors.  This change is necessary to support use
of JPEG compression on odd-size images.]

Add the following paragraphs to the Section 21 introduction (p. 89),
just after the paragraph beginning "When a Class Y image is subsampled":

	In a subsampled image, it is understood that all TIFF image
	dimensions are measured in terms of the highest-resolution
	(luminance) component.  In particular, ImageWidth, ImageLength,
	RowsPerStrip, TileWidth, TileLength, XResolution, and YResolution
	are measured in luminance samples.

	RowsPerStrip, TileWidth, and TileLength are constrained so that
	there are an integral number of samples of each component in a
	complete strip or tile.  However, ImageWidth/ImageLength are not
	constrained.  If an odd-size image is to be converted to subsampled
	format, the writer should pad the source data to a multiple of the
	sampling factors by replication of the last column and/or row, then
	downsample.  The number of luminance samples actually stored in the
	file will be a multiple of the sampling factors.  Conversely,
	readers must ignore any extra data (outside the specified image
	dimensions) after upsampling.

	When PlanarConfiguration=2, each strip or tile covers the same
	image area despite subsampling; that is, the total number of strips
	or tiles in the image is the same for each component.  Therefore
	strips or tiles of the subsampled components contain fewer samples
	than strips or tiles of the luminance component.

	If there are extra samples per pixel (see field ExtraSamples),
	these data channels have the same number of samples as the
	luminance component.

Rewrite the YCbCrSubSampling field description (pp 91-92) as follows
(largely to eliminate possibly-misleading references to
ImageWidth/ImageLength of the subsampled components):

	(first paragraph unchanged)

	The two elements of this field are defined as follows:

	Short 0: ChromaSubsampleHoriz:

	1 = there are equal numbers of luma and chroma samples horizontally.

	2 = there are twice as many luma samples as chroma samples
	horizontally.

	4 = there are four times as many luma samples as chroma samples
	horizontally.

	Short 1: ChromaSubsampleVert:

	1 = there are equal numbers of luma and chroma samples vertically.

	2 = there are twice as many luma samples as chroma samples
	vertically.

	4 = there are four times as many luma samples as chroma samples
	vertically.

	ChromaSubsampleVert shall always be less than or equal to
	ChromaSubsampleHoriz.  Note that Cb and Cr have the same sampling
	ratios.

	In a strip TIFF file, RowsPerStrip is required to be an integer
	multiple of ChromaSubSampleVert (unless RowsPerStrip >=
	ImageLength, in which case its exact value is unimportant).
	If ImageWidth and ImageLength are not multiples of
	ChromaSubsampleHoriz and ChromaSubsampleVert respectively, then the
	source data shall be padded to the next integer multiple of these
	values before downsampling.

	In a tiled TIFF file, TileWidth must be an integer multiple of
	ChromaSubsampleHoriz and TileLength must be an integer multiple of
	ChromaSubsampleVert.  Padding will occur to tile boundaries.

	The default values of this field are [ 2,2 ].  Thus, YCbCr data is
	downsampled by default!

    TIFF Tools Overview

    This software distribution comes with a small collection of programs for converting non-TIFF format images to TIFF and for manipulating and interrogating the contents of TIFF images. Several of these tools are useful in their own right. Many of them however are more intended to serve as programming examples for using the TIFF library.

    Device-dependent Programs

    There are two device-dependent programs that serve as simple examples for writing programs to display and save TIFF images.
    tiffgt     Display the contents of one or more TIFF images using OpenGL. The software makes extensive use of the TIFFRGBAImage facilities described elsewhere.
    tiffsv A program to save all or part of a screen dump on a Silicon Graphics system. As for tiffgt this code, while written to use the IRIS GL, can be easily tailored to other devices.

    Device-independent Programs

    The remaining programs should be device-independent:
    bmp2tiff Convert BMP images to TIFF
    fax2ps Convert a Group 3- or Group 4- compressed TIFF to PostScript that is significantly more compressed than is generated by tiff2ps (unless tiff2ps writes PS Level II)
    fax2tiff Convert raw Group 3 or Group 4 facsimile data to TIFF
    gif2tiff A quick hack that converts GIF 87a (old) format images to TIFF
    pal2rgb Convert a Palette-style image to a full color RGB image by applying the colormap
    ppm2tiff A quick hack that converts 8-bit PPM format images to TIFF
    ras2tiff A quick hack that converts Sun rasterfile format images to TIFF -- it's less than complete
    raw2tiff Create a TIFF file from raw data
    rgb2ycbcr Convert an RGB, grayscale, or bilevel TIFF image to a YCbCr TIFF image; it's mainly provided for testing
    sgi2tiff A program to convert SGI image files to TIFF. This program is only useful on SGI machines as it uses -limage.
    thumbnail Copy a bilevel TIFF to one that includes 8-bit greyscale "thumbnail images" for each page; it is provided as an example of how one might use the SubIFD tag (and the library support for it)
    tiff2bw A simple program to convert a color image to grayscale
    tiff2pdf Convert TIFF images to PDF
    tiff2ps Convert TIFF images to PostScript
    tiff2rgba Convert a TIFF image to RGBA color space
    tiffcmp Compare the contents of two TIFF files (it does not check all the directory information, but does check all the data)
    tiffcp Copy, concatenate, and convert TIFF images (e.g. switching from Compression=5 to Compression=1)
    tiffcrop Provides selection of images from within one or more multi-image TIFF files, with orthogonal rotation, mirroring, cropping, and extraction of multiple sections and exporting to one or more files. It extends the functionality of tiffcp to support additional bit depths in strips and tiles and enhances the selection capabilities of tiffsplit. Bilevel images can be inverted and images may be split into segments to fit on multiple /pages/ (standard paper sizes), plus other functions described in the tiffcrop man page
    tiffdither Dither a b&w image into a bilevel image (suitable for use in creating fax files)
    tiffdump Display the verbatim contents of the TIFF directory in a file (it's very useful for debugging bogus files that you may get from someone that claims they support TIFF)
    tiffinfo Display information about one or more TIFF files.
    tiffmedian A version of Paul Heckbert's median cut program that reads an RGB TIFF image, and creates a TIFF palette file as a result
    tiffset Set a field in a TIFF header
    tiffsplit Create one or more single-image files from a (possibly) multi-image file

    Check out the manual pages for details about the above programs.

    Defining New TIFF Tags

    Libtiff has built-in knowledge of all the standard TIFF tags, as well as extentions. The following describes how to add knowledge of new tags as builtins to libtiff, or how to application specific tags can be used by applications without modifying libtiff.

    TIFFFieldInfo

    How libtiff manages specific tags is primarily controlled by the definition for that tag value stored internally as a TIFFFieldInfo structure. This structure looks like this: 

    typedef	struct {
  ttag_t    field_tag;          /* field's tag */
  short	    field_readcount;    /* read count/TIFF_VARIABLE/TIFF_SPP */
  short	    field_writecount;   /* write count/TIFF_VARIABLE */
  TIFFDataType field_type;      /* type of associated data */
  unsigned short field_bit;     /* bit in fieldsset bit vector */
  unsigned char field_oktochange;/* if true, can change while writing */
  unsigned char field_passcount;/* if true, pass dir count on set */
  char	*field_name;		/* ASCII name */
} TIFFFieldInfo;
    • field_tag: the tag number. For instance 277 for the SamplesPerPixel tag. Builtin tags will generally have a #define in tiff.h for each known tag.

    • field_readcount: The number of values which should be read. The special value TIFF_VARIABLE (-1) indicates that a variable number of values may be read. The special value TIFFTAG_SPP (-2) indicates that there should be one value for each sample as defined by TIFFTAG_SAMPLESPERPIXEL. The special value TIFF_VARIABLE2 (-3) is presumably similar to TIFF_VARIABLE though I am not sure what the distinction in behaviour is. This field is TIFF_VARIABLE for variable length ascii fields.

    • field_writecount: The number of values which should be written. Generally the same as field_readcount. A few built-in exceptions exist, but I haven't analysed why they differ.

    • field_type: Type of the field. One of TIFF_BYTE, TIFF_ASCII, TIFF_SHORT, TIFF_LONG, TIFF_RATIONAL, TIFF_SBYTE, TIFF_UNDEFINED, TIFF_SSHORT, TIFF_SLONG, TIFF_SRATIONAL, TIFF_FLOAT, TIFF_DOUBLE or TIFF_IFD. Note that some fields can support more than one type (for instance short and long). These fields should have multiple TIFFFieldInfos.

    • field_bit: Built-in tags stored in special fields in the TIFF structure have assigned field numbers to distinguish them (ie. FIELD_SAMPLESPERPIXEL). New tags should generally just use FIELD_CUSTOM indicating they are stored in the generic tag list.

    • field_oktochange: TRUE if it is OK to change this tag value while an image is being written. FALSE for stuff that must be set once and then left unchanged (like ImageWidth, or PhotometricInterpretation for instance).

    • field_passcount: If TRUE, then the count value must be passed in TIFFSetField(), and TIFFGetField(), otherwise the count is not required. This should generally be TRUE for non-ascii variable count tags unless the count is implicit (such as with the colormap).

    • field_name: A name for the tag. Normally mixed case (studly caps) like "StripByteCounts" and relatively short.

    A TIFFFieldInfo definition exists for each built-in tag in the tif_dirinfo.c file. Some tags which support multiple data types have more than one definition, one per data type supported.

    Various functions exist for getting the internal TIFFFieldInfo definitions, including _TIFFFindFieldInfo(), and _TIFFFindFieldInfoByName(). See tif_dirinfo.c for details. There must be some mechanism to get the whole list, though I don't see it off hand.

    Default Tag Auto-registration

    In libtiff 3.6.0 a new mechanism was introduced allowing libtiff to read unrecognised tags automatically. When an unknown tags is encountered, it is automatically internally defined with a default name and a type derived from the tag value in the file. Applications only need to predefine application specific tags if they need to be able to set them in a file, or if particular calling conventions are desired for TIFFSetField() and TIFFGetField().

    When tags are autodefined like this the field_readcount and field_writecount values are always TIFF_VARIABLE. The field_passcount is always TRUE, and the field_bit is FIELD_CUSTOM. The field name will be "Tag %d" where the %d is the tag number.

    Defining Application Tags

    For various reasons, it is common for applications to want to define their own tags to store information outside the core TIFF specification. This is done by calling TIFFMergeFieldInfo() with one or more TIFFFieldInfos.

    The libgeotiff library provides geospatial information extentions within a TIFF file. First, a set of TIFFFieldInfo's is prepared with information on the new tags:

    static const TIFFFieldInfo xtiffFieldInfo[] = {
  
  /* XXX Insert Your tags here */
    { TIFFTAG_GEOPIXELSCALE,	-1,-1, TIFF_DOUBLE,	FIELD_CUSTOM,
      TRUE,	TRUE,	"GeoPixelScale" },
    { TIFFTAG_GEOTRANSMATRIX,	-1,-1, TIFF_DOUBLE,	FIELD_CUSTOM,
      TRUE,	TRUE,	"GeoTransformationMatrix" },
    { TIFFTAG_GEOTIEPOINTS,	-1,-1, TIFF_DOUBLE,	FIELD_CUSTOM,
      TRUE,	TRUE,	"GeoTiePoints" },
    { TIFFTAG_GEOKEYDIRECTORY, -1,-1, TIFF_SHORT,	FIELD_CUSTOM,
      TRUE,	TRUE,	"GeoKeyDirectory" },
    { TIFFTAG_GEODOUBLEPARAMS,	-1,-1, TIFF_DOUBLE,	FIELD_CUSTOM,
      TRUE,	TRUE,	"GeoDoubleParams" },
    { TIFFTAG_GEOASCIIPARAMS,	-1,-1, TIFF_ASCII,	FIELD_CUSTOM,
      TRUE,	FALSE,	"GeoASCIIParams" }
};
    In order to define the tags, we call TIFFMergeFieldInfo() on the desired TIFF handle with the list of TIFFFieldInfos.

    #define	N(a)	(sizeof (a) / sizeof (a[0]))

    /* Install the extended Tag field info */
    TIFFMergeFieldInfo(tif, xtiffFieldInfo, N(xtiffFieldInfo));
    The tags need to be defined for each TIFF file opened - and when reading they should be defined before the tags of the file are read, yet a valid TIFF * is needed to merge the tags against. In order to get them registered at the appropriate part of the setup process, it is necessary to register our merge function as an extender callback with libtiff. This is done with TIFFSetTagExtender(). We also keep track of the previous tag extender (if any) so that we can call it from our extender allowing a chain of customizations to take effect. 

    static TIFFExtendProc _ParentExtender = NULL;

static
void _XTIFFInitialize(void)
{
    static int first_time=1;
	
    if (! first_time) return; /* Been there. Done that. */
    first_time = 0;
	
    /* Grab the inherited method and install */
    _ParentExtender = TIFFSetTagExtender(_XTIFFDefaultDirectory);
}
    The extender callback is looks like this. It merges in our new fields and then calls the next extender if there is one in effect.

    static void
_XTIFFDefaultDirectory(TIFF *tif)
{
    /* Install the extended Tag field info */
    TIFFMergeFieldInfo(tif, xtiffFieldInfo, N(xtiffFieldInfo));

    /* Since an XTIFF client module may have overridden
     * the default directory method, we call it now to
     * allow it to set up the rest of its own methods.
     */

    if (_ParentExtender) 
        (*_ParentExtender)(tif);
}
    The above approach ensures that our new definitions are used when reading or writing any TIFF file. However, since on reading we already have default definitions for tags, it is usually not critical to pre-define them. If tag definitions are only required for writing custom tags, you can just call TIFFMergeFieldInfo() before setting new tags. The whole extender architecture can then be avoided.

    Adding New Builtin Tags

    A similar approach is taken to the above. However, the TIFFFieldInfo should be added to the tiffFieldInfo[] list in tif_dirinfo.c. Ensure that new tags are added in sorted order by the tag number.

    Normally new built-in tags should be defined with FIELD_CUSTOM; however, if it is desirable for the tag value to have it's own field in the TIFFDirectory structure, then you will need to #define a new FIELD_ value for it, and add appropriate handling as follows:

    1. Define the tag in tiff.h.
    2. Add a field to the directory structure in tif_dir.h and define a FIELD_* bit (also update the definition of FIELD_CODEC to reflect your addition).
    3. Add an entry in the TIFFFieldInfo array defined at the top of tif_dirinfo.c. Note that you must keep this array sorted by tag number and that the widest variant entry for a tag should come first (e.g. LONG before SHORT).
    4. Add entries in _TIFFVSetField() and _TIFFVGetField() for the new tag.
    5. (optional) If the value associated with the tag is not a scalar value (e.g. the array for TransferFunction) and requires special processing, then add the appropriate code to TIFFReadDirectory() and TIFFWriteDirectory(). You're best off finding a similar tag and cribbing code.
    6. Add support to TIFFPrintDirectory() in tif_print.c to print the tag's value.

    If you want to maintain portability, beware of making assumptions about data types. Use the typedefs (uint16, etc. when dealing with data on disk and t*_t when stuff is in memory) and be careful about passing items through printf or similar vararg interfaces.

    Adding New Codec-private Tags

    To add tags that are meaningful only when a particular compression algorithm is used follow these steps:
    1. Define the tag in tiff.h.
    2. Allocate storage for the tag values in the private state block of the codec.
    3. Insure the state block is created when the codec is initialized.
    4. At TIFFInitfoo time override the method pointers in the TIFF structure for getting, setting and printing tag values. For example, 
          sp->vgetparent = tif->tif_vgetfield;
    tif->tif_vgetfield = fooVGetField;	/* hook for codec tags */
    sp->vsetparent = tif->tif_vsetfield;
    tif->tif_vsetfield = fooVSetField;	/* hook for codec tags */
    tif->tif_printdir = fooPrintDir;	/* hook for codec tags */
      (Actually you may decide not to override the tif_printdir method, but rather just specify it).
    5. Create a private TIFFFieldInfo array for your tags and merge them into the core tags at initialization time using _TIFFMergeFieldInfo; e.g. 
          _TIFFMergeFieldInfo(tif, fooFieldInfo, N(fooFieldInfo));
      (where N is a macro used liberaly throughout the distributed code).
    6. Fill in the get and set routines. Be sure to call the parent method for tags that you are not handled directly. Also be sure to set the FIELD_* bits for tags that are to be written to the file. Note that you can create ``pseudo-tags'' by defining tags that are processed exclusively in the get/set routines and never written to file (see the handling of TIFFTAG_FAXMODE in tif_fax3.c for an example of this).
    7. Fill in the print routine, if appropriate.
    Note that space has been allocated in the FIELD_* bit space for codec-private tags. Define your bits as FIELD_CODEC+<offset> to keep them away from the core tags. If you need more tags than there is room for, just increase FIELD_SETLONGS at the top of tiffiop.h.

    This document describes the changes made to the software between the previous and current versions (see above). If you don't find something listed here, then it was not done in this timeframe, or it was not considered important enough to be mentioned. The following information is located here:

    MAJOR CHANGES:
    • Fixes a number of bugs present in the 3.9.1 release.
    • OJPEG support updated to work with IJG JPEG 7 release.
    • Tiffcrop validated for most TIFF storage subformats and sample depths.

    CHANGES IN THE SOFTWARE CONFIGURATION:
    • x86_64 now uses the same default fill order as i386.

    CHANGES IN LIBTIFF:
    • Writing tags with an array value of type TIFF_DOUBLE now returns correct error status. The TIFFTAG_SMINSAMPLEVALUE and TIFFTAG_SMAXSAMPLEVALUE tags failed to write without this fix.
    • OJPEG decoder now works with IJG JPEG 7. Resolves "Bug 2090 - OJPEG crash with libjpeg v7". http://bugzilla.maptools.org/show_bug.cgi?id=2090
    • Eliminate most GCC "dereferencing type-punned pointer" warnings.

    CHANGES IN THE TOOLS:
    • New tiffcrop from Richard Nolde. Major updates to add significant functionality for reading and writing tile based images with bit depths not a multiple of 8 which cannot be handled by tiffcp.
    • Allow building tools with GCC using the "-Wformat -Werror=format-security" flags.

    CHANGES IN THE CONTRIB AREA:
    • None

    This document describes the changes made to the software between the previous and current versions (see above). If you don't find something listed here, then it was not done in this timeframe, or it was not considered important enough to be mentioned. The following information is located here:

    MAJOR CHANGES:
    • The code has been reviewed by Dmitry Levin: added checks for values, returned by the space allocation functions, fixed problems with the possible integer overflows.

    CHANGES IN THE SOFTWARE CONFIGURATION:
    • Several fixes in the test suite.

    CHANGES IN LIBTIFF:
    • Preliminary support for BigTIFF files: now libtiff can recognize and reject to open such images. ;-)
    • libtiff/tif_dirinfo.c: changed type of XMLPacket (tag 700) to TIFFTAG_BYTE instead of TIFFTAG_UNDEFINED to comply with the info in the Adobe XMP Specification.
    • Added many checks for integer overflow and for successful space allocations in the different parts of library. Code review completed by Dmitry V. Levin.
    • libtiff/{tiffio.h, tif_compress.c}: Added TIFFGetConfiguredCODECs()function to get the list of configured codecs.

    CHANGES IN THE TOOLS:
    • tiff2bw: Write ImageWidth/Height tags to output file, as noted by Gennady Khokhorin.

    CHANGES IN THE CONTRIB AREA:
    • No changes.
    CHANGES IN THE LZW COMPRESSION KIT:
    • This one is not longer needed.
