To view the documentation point your favorite WWW viewer at html/index.html; e.g. netscape html/index.html If you don't have an HTML viewer then you can read the HTML source or fetch a PostScript version of this documentation from the directory ftp://ftp.sgi.com/graphics/tiff/doc If you can't hack either of these options then basically what you want to do is: % ./configure % make % su # make install If that doesn't do what you want, or something isn't clear then sorry, but you're SOL.

By default, each row of data in the resultant .SM TIFF file is 2-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 \-2 Assume input data is 2-d Huffman encoded. .TP .B \-B Assume input data was encoded with black as 0 and white as 1. .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 ). (This is the default.) .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 \-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 \-W Assume input data was encoded with black as 1 and white as 0. (This is the default.) .PP Options that affect the output file format are: .TP .B \-1 Force output to be compressed with the 1-dimensional version of the .SM CCITT Group 3 Huffman encoding algorithm. .TP .B \-4 Force output to be compressed with the .SM CCITT Group 4 Huffman encoding. .TP .B \-o Specify the name of the output file. .TP .B \-p Force the last bit of each .I "End Of Line" (\c .SM EOL\c ) code to land on a byte boundary. This ``zero padding'' will be reflected in the contents of the .I Group3Options tag of the resultant .SM TIFF file. .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. .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 value of 1728. 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. The remainder of the input row is discarded, while the corresponding output row is padded with white. .PP .BR "%s: Bad 2D code word at scanline %d.\en" . An invalid Group 4 or 2D Group 3 .I 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. .SH BUGS Should not have the constant width 1728 built into it. Input data are assumed to have a a ``top left'' orientation; it should be possible to override this assumption from the command line. .SH "SEE ALSO" .I "\s-1CCITT\s+1 Recommendation T.4" (Standardization of Group 3 Facsimile Apparatus for Document Transmission). .PP .IR "The Spirit of TIFF Class F" , an appendix to the TIFF 5.0 specification prepared by Cygnet Technologies. .PP .IR tiffinfo (1), .IR tiffdither (1), .IR tiffgt (1), .IR libtiff (3).

The .B \-x and .B \-y options can be used to specify the horizontal and vertical image resolutions (lines/inch), respectively. If the .B \-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 .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 .IR 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.

By default, .I tiff2ps writes Encapsulated PostScript for the first image in the specified .SM TIFF image file. .PP By default, .I tiff2ps will generate PostScript 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 PostScript generated for .SM RGB, palette, and .SM CMYK images uses the .I colorimage operator. The PostScript generated for greyscale and bilevel images uses the .I image operator. When the .I 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. .PP Color images with associated alpha data are composited over a white background. .SH OPTIONS .TP .B \-1 Generate PostScript Level I (the default). .TP .B \-2 Generate PostScript Level II. .TP .B \-a Generate output for all IFDs (pages) in the input file. .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 PostScript. .TP .B \-h Specify the vertical size of the printed area (in inches). .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 SubIFD tag. .TP .B \-p Force the generation of (non-Encapsulated) PostScript. .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). .SH EXAMPLES The following generates PostScript Level II 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 PostScript 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.) .SH BUGS Because PostScript does not support the notion of a colormap, 8-bit palette images produce 24-bit PostScript images.

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 .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 g3 for CCITT Group 3 (T.4) compression, .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 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 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 \-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 \-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, .I tiffcp attempts to set the rows/strip that no more than 8 kilobytes of data appear in a strip. .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 wtih 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. .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.) .SH "SEE ALSO" .IR pal2rgb (1), .IR tiffinfo (1), .IR tiffcmp (1), .IR tiffmedian (1), .IR tiffsplit (1), .IR libtiff (3) H 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.) .SH "SEE ALSO" .IR pal2rgb (1), .IR tiffinfo (1), .IR tiffcmp (1), .IR tiffmedian (1), .IR tiffsplit (1),tiff-v3.4beta018/man/tiffdither.1000444 004341 000024 00000007266 06003063002 016336 0ustar00samuser000000 000000 .\" $Header: /usr/people/sam/tiff/man/RCS/tiffdither.1,v 1.14 1995/07/07 23:29:04 sam Exp $ .\" .\" Copyright (c) 1990, 1991, 1992, 1993, 1994 Sam Leffler .\" Copyright (c) 1991, 1992, 1993, 1994 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 TIFFDITHER 1 "September 26, 1994" .SH NAME tiffdither \- convert a greyscale image to bilevel using dithering .SH SYNOPSIS .B tiffdither [ .I options ] .I input.tif .I output.tif .SH DESCRIPTION .I tiffdither converts a single channel 8-bit greyscale image to a bilevel image using Floyd-Steinberg error propagation with threholding. .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, .B g3 for CCITT Group 3 (T.4) compression, .B g4 for CCITT Group 4 (T.6) compression.

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 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) .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 PhotomatricInterpretation =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 . .SH OPTIONS .TP .B \-c Force image display in a colormap window. .TP .B \-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. .TP .B \-f Force .I tiffgt to run as a foreground process.

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, 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, 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 overriden, 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).

The file must have been previously opened with .IR TIFFOpen (3T). 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 (\c or, on some machines, the .IR varargs (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 , 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 (3T). Remember that .IR TIFFGetField returns parameter values, so all the listed data types are pointers to storage where values should be returned. Consult the .SM TIFF specification for information on the meaning of each tag and their possible values. .PP .nf .ta \w'TIFFTAG_CONSECUTIVEBADFAXLINES'u+2n +\w'Count'u+2n +\w'uint16*,uint16**'u+2n \fITag Name\fP \fICount\fP \fITypes\fP \fINotes\fP .sp 5p TIFFTAG_ARTIST 1 char** TIFFTAG_BADFAXLINES 1 uint32* TIFFTAG_BITSPERSAMPLE 1 uint16* TIFFTAG_CLEANFAXDATA 1 uint16* TIFFTAG_COLORMAP 3 uint16** 1<" .B "TIFF* TIFFOpen(const char* filename, const char* mode)" .sp 5p .B "TIFF* TIFFFdOpen(const int fd, const char* filename, const char* mode)" .sp 5p .B "typedef tsize_t (*TIFFReadWriteProc)(thandle_t, tdata_t, tsize_t);" .B "typedef toff_t (*TIFFSeekProc)(thandle_t, toff_t, int);" .B "typedef int (*TIFFCloseProc)(thandle_t);" .B "typedef toff_t (*TIFFSizeProc)(thandle_t);" .B "typedef int (*TIFFMapFileProc)(thandle_t, tdata_t*, toff_t*);" .B "typedef void (*TIFFUnmapFileProc)(thandle_t, tdata_t, toff_t);" .sp 5p .B "TIFF* TIFFClientOpen(const char* filename, const char* mode, thandle_t clientdata," .B " TIFFReadWriteProc readproc, TIFFReadWriteProc writeproc, TIFFSeekProc seekproc," .B " TIFFCloseProc closeproc, TIFFSizeProc sizeproc, TIFFMapFileProc mapproc," .B " TIFFUnmapFileProc unmapproc)" .fi .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''). 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 (3T) 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 (3T) must be used. .PP It is not possible to append data to a file that has a byte ordering opposite to the native byte ordering of a machine. That is, for example, the library will not allow a file with little-endian byte ordering to be appended to on a machine that has a native big-endian byte ordering. .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 "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 (3T) routine. Likewise, warning messages are directed to the .IR TIFFWarning (3T) routine. .PP \fB"%s": Bad mode\fP.

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 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 TIFFReadRGBAImage converts non-8-bit images by scaling sample values. Palette, grayscale, bilevel, CMYK, and YCbCr images are converted to .SM RGB transparently. Raster pixels are returned uncorrected by any colorimetry information present in the directory. .PP The paramater .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 TIFFReadRGBAImage will continue processing data until all the possible data in the image have been requested. .SH NOTES In C++ the .I stopOnError parameter defaults to 0. .PP Samples must be either 1, 2, 4, 8, or 16 bits. Samples/pixel must be either 1, 3, or 4. .PP Palettte image colormaps that appear to be incorrectly written as 8-bit values are automatically scaled to 16-bits. .SH "RETURN VALUES" 1 is returned 1 if the image was successfully read and converted. 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 (3T) 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" . The image had .I SamplesPerPixel other than 1, 3, or 4. .PP \fBMissing needed "PhotometricInterpretation" tag\fP. The image did not have a tag that describes how to display the data. .PP \fBNo "PhotometricInterpretation" tag, assuming RGB\fP. 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 .SM RGB. .PP \fBNo "PhotometricInterpretation" tag, assuming min-is-black\fP. 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. .PP .BR "No space for photometric conversion table" .

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 (3T) 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 (3T) routine. .PP .BR "%s: File not open for writing .

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), 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), and NeXT's 2-bit compression algorithm (32766) (decompression only). 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 uint32; 'u .nf typedef unsigned short uint16; 16-bit unsigned integer typedef unsigned 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 available. Consult specific manual pages for details on their operation. (The manual page names give here are for systems where the full function names can not be encoded in the filesystem; on most systems doing ``man function-name'' will work.) .sp 5p .nf .ta \w'TIFFWriteEncodedStrip'u+2n +\w'Appears on Page'u+2n \fIName\fP \fIAppears on Page\fP \fIDescription\fP .sp 5p TIFFCheckTile tile.3t very x,y,z,sample is within image TIFFClientOpen open.3t open a file for reading or writing TIFFClose close.3t close an open file TIFFComputeStrip strip.3t return strip containing y,sample TIFFComputeTile tile.3t return tile containing x,y,z,sample TIFFCurrentDirectory query.3t return index of current directory TIFFCurrentRow query.3t return index of current scanline TIFFCurrentStrip query.3t return index of current strip TIFFCurrentTile query.3t return index of current tile TIFFError error.3t library error handler TIFFFdOpen open.3t open a file for reading or writing TIFFFileName query.3t return name of open file TIFFFileno query.3t return open file descriptor TIFFFlush flush.3t flush all pending writes TIFFFlushData flush.3t flush pending data writes TIFFGetBitRevTable swab.3t return bit reversal table TIFFGetField getfield.3t return tag value in current directory TIFFGetFieldDefaulted getfield.3t return tag value in current directory TIFFGetMode query.3t return open file mode TIFFGetVersion query.3t return library version string TIFFIsTiled query.3t return true if image data is tiled TIFFIsByteSwapped query.3t return true if image data is byte-swapped TIFFNumberOfStrips strip.3t return number of strips in an image TIFFNumberOfTiles tile.3t return number of tiles in an image TIFFOpen open.3t open a file for reading or writing TIFFPrintDirectory print.3t print description of the current directory TIFFReadBufferSetup rdbuf.3t specify i/o buffer for reading TIFFReadDirectory readdir.3t read the next directory TIFFReadEncodedStrip rdestrip.3t read and decode a strip of data TIFFReadEncodedTile rdetile.3t read and decode a tile of data TIFFReadRawStrip rdrstrip.3t read a raw strip of data TIFFReadRawTile rdrtile.3t read a raw tile of data TIFFReadRGBAImage rdimage.3t read an image into a fixed format raster TIFFReadScanline readline.3t read and decode a row of data TIFFReadTile readtile.3t read and decode a tile of data TIFFReverseBits swab.3t reverse bits in an array of bytes TIFFScanlineSize size.3t return size of a scanline TIFFSetDirectory setdir.3t set the current directory TIFFSetErrorHandler error.3t set error handler function TIFFSetField setfield.3t set a tag's value in the current directory TIFFSetWarningHandler error.3t set warning handler function TIFFStripSize size.3t return size of a strip TIFFSwabShort swab.3t swap bytes of short TIFFSwabLong swab.3t swap bytes of long TIFFSwabArrayOfShort swab.3t swap bytes of an array of shorts TIFFSwabArrayOfLong swab.3t swap bytes of an array of longs TIFFTileRowSize size.3t return size of a row in a tile TIFFTileSize size.3t return size of a tile TIFFVGetField getfield.3t return tag value in current directory TIFFVGetFieldDefaulted getfield.3t return tag value in current directory TIFFVSetField setfield.3t set a tag's value in the current directory TIFFWarning warning.3t library warning handler TIFFWriteDirectory writedir.3t write the current directory TIFFWriteEncodedStrip wrestrip.3t compress and write a strip of data TIFFWriteEncodedTile wretile.3t compress and write a tile of data TIFFWriteRawStrip wrrstrip.3t write a raw strip of data TIFFWriteRawTile wrrtile.3t write a raw tile of data TIFFWriteScanline writeline.3t write a scanline of data TIFFWriteTile wrrtile.3t compress and write a tile of data .fi .SH "TAG USAGE" The table below lists the .SM TIFF tags that are recognized and handled by the library.

Building the Software Distribution

This documentation is best viewed using a graphical browser that supports the latest HTML directives for formatting documents. In particular, this document was authored for viewing with version 1.1 or newer of the Netscape Navigator.

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 to build the software and then make install to do the installation; for example: 
    hyla% cd tiff-v3.4beta099
hyla% ./configure
    ...lots of messages...
hyla% make
    ...lots of messages...
hyla# make install
In general, the software is designed such that the following should be ``make-able'' in each directory: 
    make [all]	build stuff
make install	build&install stuff
make clean	remove .o files and cruft, but not executables
make clobber	remove everything that can be recreated
make distclean	remove absolutely everything that can be recreated
Note that after running "make clobber" or "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% cd tiff-v3.4beta099
hyla% ls
COPYRIGHT       VERSION         config.sub      dist            man
Makefile.in     config.guess    configure       html            port
README          config.site     contrib         libtiff         tools
hyla% ./configure

Otherwise, you can configure a build tree that is parallel to the source tree hierarchy but which contains only configured files and files created during the build procedure. 

    hyla% cd tiff-v3.4beta099
hyla% mkdir obj obj/mycpu
hyla% cd obj/mycpu
hyla% ../../configure
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)
Beware that if you choose to use the second scheme for configuring the software you must not use an absolute pathname when you run configure (i.e. a pathname that begins with ``/'') and the make that you use to build the software must correctly support the VPATH facility.

NOTE: HPUX 9.05: The standard make incorrectly processes VPATH; either use gmake or configure builds in the source tree.

Configuration Files

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 sample configure run is shown below together with an explanation of some of the work that is done.

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 either:

  • on the command line to configure,
  • in a site-wide configuration file, or
  • in a target-specific configuration file.
configure reads any site-wide configure file first, and then any target-specific configuration file. This permits target-specific definitions to override site-wide definitions.

Site-wide configuration files are named config.site and are automatically searched for first in any directory specified on the command line to configure (using the -site option), or if that fails, in the directory in in which the configure script is located.

Target-specific configuration files are named config.local and are looked for first in the top-level configuration directory, or, if that fails, in the directory in which the configure script is located.

Configuration files are just shell scripts that define shell variables that control the configuration process. For example, the following file might be used on a BSDI system to configure the software for installation in the /usr/contrib area and to make use of the Adobe Font Metric files that are already distributed as part of the BSDI 1.1 distribution: 

#
# Parameters suitable for BSDI 1.1
#
DIR_BIN="/usr/contrib/bin"		# directory for client apps
DIR_LIB="/usr/contrib/lib"		# directory for libraries
DIR_MAN="/usr/contrib/man"		# directory for manual pages
DIR_HTML="/usr/contrib/html/tiff"	# directory for HTML documentation

For a complete list of the possible configuration parameters, look at the sample config.site file provided in the distribution or check the section below.

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 in a config.site or config.local file, or by using a -with-<PACKAGE> option when invoking configure; e.g. configure -with-AFM.
DSO Support
The DSO support controls whether or not to configure the software to build a Dynamic Shared Object for the TIFF library. Use of DSOs can significantly reduce the disk space needed for users of the TIFF software. If DSOs are not used then the code is statically linked into each application that uses it. By default this support is configured only if the system appears to suport DSOs in a way that fits into the normal build scheme (auto). If DSO support is explicitly enabled and there is no support for using DSOs in the expected way then DSOs are not used.

HTML Package
The HTML package contains this HTML documentation about TIFF. By default this package is not configured for installation since HTML documentation can be viewed directly from the source directory. You may want to configure the installation of the HTML materials if these documents are going to be shared by many people.

JPEG Support
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. By default JPEG support is not configured.

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. By default this package is not configured.

A Sample Configuration Session

 This section shows a sample configuration session and describes the work done. The session is shown indented in a fixed width font with user-supplied input in a bold font. Comments are shown in a normal or italic font. This session was collected on a 486 machine running BSDI 1.1. 
    
wullbrandt% mkdir tiff
wullbrandt% cd tiff
wullbrandt% ln -s /hosts/oxford/usr/people/sam/tiff src
A build tree separate from the source tree is used here. In fact, in this case the distribution is accessed from a read-only NFS-mounted filesystem. 
    
wullbrandt% src/configure
Configuring TIFF Software v3.4beta015.

Reading site-wide parameters from ../tiff-v3.4beta015/config.site.
Reading local parameters from config.local.
Gosh, aren't you lucky to have a i386-unknown-bsdi1.1 system!
Note that configure announces the distribution version and the deduced target configuration (i386-unknown-bsdi1.1 here). 
    
Using /usr/local/bin/gcc for a C compiler (set CC to override).
Looks like /usr/local/bin/gcc supports the -g option.
Using " -g" for C compiler options.
configure checked the normal shell search path for potential ANSI C compilers. The compiler is selected according to it properly compiling a small ANSI C test program. A specific compiler may be requested by setting the CC environment variable to the appropriate pathname, by supplying the parameter on the command line, e.g. -with-CC=gcc, or by setting CC in a configuration file.

Note that an ANSI C compiler is required to build the software. If a C compiler requires options to enable ANSI C compilation, they can be specified with the ENVOPTS parameter.

Once a compiler is selected configure does several checks to see:

  • if the compiler accepts a -g option to enable the generation of debugging symbols, and
  • if the compiler includes an ANSI C preprocessor. 
    
Using /usr/ucb/make to configure the software.
Next various system-specific libraries that may or may not be needed are checked for (none are needed in this case). If your system requires a library that is not automatically included it can be specified by setting the MACHDEPLIBS parameter.

Creating port.h. The port.h file is included by all the C code in the system. It includes definitions for functions and type definitions that are missing from system include files, #defines to enable or disable system-specific functionality, and other odds and ends. 

    
Creating port.h with necessary definitions.
... using LSB2MSB bit order for your i386 cpu
... using big-endian byte order for your i386 cpu
... configure use of mmap for memory-mapped files
... O_RDONLY is in 
... using double for promoted floating point parameters
... enabling use of inline functions
Done creating port.h.
This file can take a long time to create so configure generates the file only when it is needed, either because the file does not exist or because a different target or compiler is to be used. Note that running "make distclean" in the top-level directory of the build tree will remove the port.h file (along with all the other files generated by configure).

Selecting emulated library functions. Certain functions used by the software are not present on all systems and can be emulated using other system functionality. configure checks for the presence of such functions and if they are missing, will configure emulation code from the port directory to use instead. Building the TIFF software on unsupported systems may require adding to the code to the port directory. 

    
Checking system libraries for functionality to emulate.
Done checking system libraries.
If a routine must be emulated and configure does not automatically check for it, the routine name can be specified using the PORTFUNCS parameter. To add emulation support for a new function foo, create a file port/foo.c that contains the emulation code and then set PORTFUNCS=foo in a configuration file or modify the configure script to automatically check for the missing function. 
    
Checking for Dynamic Shared Object (DSO) support.
Done checking for DSO support.
If the DSO package is enabled (DSO=auto or DSO=yes), then configure will verify the system and compiler are capable of constructing SVR4-style DSO's in the expected way. Note that while a system may support DSO's the compiler may not be capable of generating the required position-independent code and/or the compiler may not pass the needed options through to the loader.

Selecting utility programs. configure locates various system utility programs that are used during installation of the software. 

    
Selecting programs used during installation.
Looks like mv supports the -f option to force a move.
Looks like /bin/ln supports the -s option to create a symbolic link.
Done selecting programs.

Selecting default configuration parameters. The remainder of the work done by configure involves setting up configuration parameters that control the placement and setup of files during the installation procedure. 

    
Selecting default TIFF configuration parameters.

Looks like manual pages go in /usr/contrib/man.
Looks like manual pages should be installed with bsd-nroff-gzip-0.gz.

TIFF configuration parameters are:

[ 1] Directory for tools:               /usr/contrib/bin
[ 2] Directory for libraries:           /usr/contrib/lib
[ 3] Directory for include files:       /usr/contrib/include
[ 4] Directory for manual pages:        /usr/contrib/man
[ 5] Directory for HTML documentation:  /var/httpd/htdocs/tiff
[ 6] Manual page installation scheme:   bsd-nroff-gzip-0.gz

Are these ok [yes]?
At this point you can interactively modify any of the displayed parameters. Hitting a carriage return or typing yes will accept the current parameters. Typing one of the number displayed along the left hand side causes configure to prompt for a new value of the specified parameter. Typing anything else causes configure to prompt for a new value for each parameter. In general hitting carriage return will accept the current value and typing anything that is unacceptable will cause a help message to be displayed. A description of each of the configuration parameters is given below.

Once acceptable parameters are setup configure will generate all the files that depend on these parameters. Note that certain files may or may not be created based on the configuration of optional packages and/or the functions supported by target system. 

    
Creating Makefile from ../tiff-v3.4beta015/Makefile.in
Creating libtiff/Makefile from ../tiff-v3.4beta015/libtiff/Makefile.in
Creating man/Makefile from ../tiff-v3.4beta015/man/Makefile.in
Creating tools/Makefile from ../tiff-v3.4beta015/tools/Makefile.in
Creating port/install.sh from ../tiff-v3.4beta015/port/install.sh.in
Done.

Configuration Parameters

 This section gives a brief description of the less obvious configuration parameters. Consult the distributed config.site for a complete list of parameters. The list here is sorted alphabetically.

AROPTS The options passed to ar when creating an archive. Note that configure will automatically check to see if ar supports an s to create a symbol table instead of using ranlib.
DIR_BIN The directory where client applications should be installed; by default this is /usr/local/bin.
DIR_HTML The directory where HTML-based documentation should be installed; by default this is /var/httpd/htdocs/tiff (usually appropriate for the NCSA HTTP server).
DIR_LIB The directory to install libraries and DSO's; by default this is /usr/local/lib.
DIR_MAN The top-most directory of the manual area where manual pages should be installed.
DSOOPTS When DSO's are built, the options to specify to CC to create a DSO.
DSOSUF When DSO's are built, the filename suffix for a DSO. If this is set to "a" then statically linked archives are used.
ENVOPTS Options to pass to CC to force ANSI C compilation.
FILLORDER The order of bits in a byte on the server machine; either LSB2MSB or MSB2LSB. This is normally selected according to the target system.
GCOPTS Special options to pass the C compiler. If this parameter is set, then configure may append other options to this list.
INSTALL The pathname of the install program to use. Note that this program must emulate the command line interface used by the IRIX install program.
LIBPORT The pathname of the library that holds code to emulate missing system functionality. Normally this parameter is set by configure based on whether or not emulation code is required for the target.
LLDOPTS Extra command line options passed to CC when linking an executable. This option is usually set only when DSO support is enabled (to force the executable to search for the TIFF DSO in non-standard locations in the filesystem.)
MACHDEPLIBS Target-dependent libraries that should be used when linking tools. Note that if this parameter is specified configure will append to the list of libraries.
MANSCHEME The scheme to use when preparing and installing manual pages. Schemes are constructed according to:
    <organization>-<formatting>-<compression>[-<suffix>]
where: <organization> is either bsd for BSD-style section organization (e.g. file formats in section 5) or sysv for System V-style organization (e.g. file formats in section 4). <formatting> is either nroff to force installation of formatted materials (using nroff) or source to get the nroff source installed. <compression> is either the name of a program to compress the manual pages (gipz, compress, pack) or cat for uncompressed data. <suffix> is either the file suffix to convert installed pages to (e.g. 0.gz for gzip-compressed pages under BSD) or strip to force the normal ".4f" suffix to be converted to ".4" (or ".5" if using the BSD organization). If no -<suffix> is specified then filenames are not converted when they are installed.
PORTFUNCS A list of non-standard functions that should be emulated. Normally this list is constructed by configure based on checks it does. If this parameter is set, configure will append to the specified list.
SETMAKE If make does not automatically set $MAKE to the name of the make program to invoke for subdirectories, then configure will create an explicit definition. If this parameter is set, then it will be used instead. by default bin is used.

Building the Software under MS/DOS or Windows

There is a Makefile for Microsoft C. There is OS support for MS-DOS and for Windows. Someone needs to fill this in....

Building the Software on a Macintosh

 The directory contrib/mac-mpw contains support for compiling the library and tools under the MPW Shell on a Macintosh system. This support was contributed by Niles Ritter (ndr@tazboy.jpl.nasa.gov).

[From the file contrib/mac-mpw/README.]

This directory contains all of the utilities and makefile source to build the LIBTIFF library and tools from the MPW Shell. The file BUILD.mpw in this directory is an executable script which uses all of these files to create the MPW makefiles and run them.

The .make files are not MPW makefiles as such, but are when run through the "mactrans" program, which turns the ascii "%nn" metacharacters into the standard weird MPW make characters.

This translation trick is necessary to protect the files when they are put into unix tarfiles, which tend to mangle the special characters.

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
$ TIFFCP    :==$DISK:[TIFF.TOOLS]TIFFCP
$ TIFFCMP   :==$DISK:[TIFF.TOOLS]TIFFCMP
$ TIFFINFO  :==$DISK:[TIFF.TOOLS]TIFFINFO
$ TIFFDUMP  :==$DISK:[TIFF.TOOLS]TIFFDUMP
$ TIFF2PS   :==$DISK:[TIFF.TOOLS]TIFF2PS
$ TIFFDITHER:==$DISK:[TIFF.TOOLS]TIFFDITHER
$ TIFF2BW   :==$DISK:[TIFF.TOOLS]TIFF2BW
$ TIFFMEDIAN:==$DISK:[TIFF.TOOLS]TIFFMEDIAN
$ TIFFSPLIT :==$DISK:[TIFF.TOOLS]TIFFSPLIT
$ FAX2TIFF  :==$DISK:[TIFF.TOOLS]FAX2TIFF
$ GIF2TIFF  :==$DISK:[TIFF.TOOLS]GIF2TIFF
$ PAL2RGB   :==$DISK:[TIFF.TOOLS]PAL2RGB
$ PPM2TIFF  :==$DISK:[TIFF.TOOLS]PPM2TIFF
$ RAS2TIFF  :==$DISK:[TIFF.TOOLS]RAS2TIFF
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 pre-release was tested under OpenVMS/AXP ?.? using DEC C ?.?, it is believed that the 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 ", 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. The 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,SYS$INPUT:/OPTIONS
    SYS$SHARE:VAXCRTL/SHAREABLE
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.

On the AXP, the C runtime library is linked automatically, this means that 

    SYS$INPUT:/OPTIONS
	SYS$SHARE:VAXCRTL/SHAREABLE
should not be used.

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 by on-the-fly. The file tif_fax3sm.c has the state tables for the Group 3 and Group 4 decoders. This file is normally 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
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 a UNIX system using commands that can be found in the file Makefile.in. An example copy of version.h is:

    #define VERSION "LIBTIFF, Version 3.4beta015 \nCopyright (c) 1988-1995 Sam Leffler\nCopyright (c) 1991-1995 Silicon Graphics, Inc."

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).

    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.sgi.com/graphics/tiff/v3.0pics.tar.Z.

    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 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, as are a number of TIFF Technical Notes (TTN's).

    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 on UNIX systems, and documentation on the library and tools. A small assortment of TIFF-related software for UNIX that has been contributed by others is also included.

    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. This software can also be used on older 16-bit systems though it may require some effort and you may need to leave out some of the compression support.

    The following sections are included in this documentation:

    A PostScript version of this documentation is available on-line at the master FTP site listed above.

    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 Lempel-Ziv & Welch (LZW) algorithm (compression 5), a 4-bit run-length encoding scheme from ThunderScan (compression 32809), and a 2-bit encoding scheme used by NeXT (compression 32766). To override this 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 0.92 or later of the freely available libgz 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:/graphics/jpeg/.

    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 support for memory mapping files.
    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:

    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 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 Tags

     To add support for a new directory tag you have three options. If your tag is specific to a compression algorithm, see below. If you have a lot of tags you may want to try using Niles Ritter's runtime tag-extension scheme in the "contrib/tags" directory, which makes the changes orthogonal to the main libtiff code. Otherwise use the following guidelines to add support to the ``core library''.
    1. Define the tag in tiff.h.
    2. Add a field to the directory structure in tif_dir.h and define a FIELD_* bit.
    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 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, above), 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.

    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.

    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, libitff/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.

    Introduction to the TIFF Documentation

    This documentation is best viewed using a graphical browser that supports the latest HTML directives for formatting documents. In particular, this document was authored for viewing with version 1.1 or newer of the Netscape Navigator.

    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.

Using The TIFF Library

This documentation is best viewed using a graphical browser that supports the latest HTML directives for formatting documents. In particular, this document was authored for viewing with version 1.1 or newer of the Netscape Navigator.

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

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.

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 = 1; 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 implements 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, raster, w, h, 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.width)) { ...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); } }

The LZW algorithm is derived from the compress program (the proper attribution is included in the source code). The Group 3 fax stuff originated as code from Jef Poskanzer, but has since been rewritten several times. The latest version uses an algorithm from Frank Cringle -- consult libtiff/mkg3states.c and libtiff/tif_fax3.h for further information. The JPEG support was written by Tom Lane and is dependent on the excellent work of Tom Lane and the Independent JPEG Group (IJG) who distribute their work under friendly licensing similar to this software.

Warning

It appears that Unisys is actively pursuing copyright control on the LZW compression algorithm. In particular, users of the LZW compression within the TIFF framework. For this reason the TIFF 6.0 spec states that LZW compression is not recommended. It is unclear at this time what compression algorithm will be used in place of it. I have no idea what this means to you or to this library. I make no warranty or guarantees with regard to the LZW support in this library.

Sam Leffler / Netscape Navigator.

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.

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).

Sam Leffler / TIFF Tools Overview

TIFF Tools Overview

This documentation is best viewed using a graphical browser that supports the latest HTML directives for formatting documents. In particular, this document was authored for viewing with version 1.1 or newer of the Netscape Navigator.

This software distribution comes with a small collection of programs for converting non-TIFF format images to TIFF and for manipulating and interogating 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 on a Silicon Graphics system using the Silicon Graphics IRIS GL. 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:

tiffinfo Display information about one or more TIFF 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)
tiffcp Copy, concatenate, and convert TIFF images (e.g. switching from Compression=5 to Compression=1)
tiff2ps Convert TIFF images to PostScript
tiffcmp Compare the contents of two TIFF files (it does not check all the directory information, but does check all the data)
tiff2bw A simple program to convert a color image to grayscale
ras2tiff A quick hack that converts Sun rasterfile format images to TIFF -- it's less than complete
rgb2ycbcr Convert an RGB, grayscale, or bilevel TIFF image to a YCbCr TIFF image; it's mainly provided for testing
gif2tiff A quick hack that converts GIF 87a format images to TIFF
ppm2tiff A quick hack that converts PPM format images to TIFF
fax2tiff Convert raw Group 3 or Group 4 facsimile data to TIFF
pal2rgb Convert a Palette-style image to a full color RGB image by applying the colormap
tiffdither Dither a b&w image into a bilevel image (suitable for use in creating fax files)
tiffsplit Create one or more single-image files from a (possibly) multi-image file
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)
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)
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; it's useful for converting full-color RGB images to 8-bit color for your friends that have cheapo 8-bit framebuffers.
sgi2tiff A program to convert SGI image files to TIFF. This program is only useful on SGI machines as it uses -limage.

Check out the manual pages for details about the above programs.

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 recognizes IRIX 6.x systems
  • configure now uses ENVOPTS when searching for an ANSI C compiler; this fixes a problem configuring the software under HP/UX with the native C compiler
  • configure now correctly recognizes memory-mapped files are supported under AIX

CHANGES IN LIBTIFF:
  • make install now properly installs the include files
  • some portability fixes from Bjorn Brox
  • the G3/G4 codec now warns about decoded rows that are longer than the image/tile width
  • changes from Frank Cringle to make the library work with the gcc-specific bounds checking software
  • miscellaneous fixes to TIFFPrintDirectory
  • bug fix to correct a problem where TIFFWriteRawStrip could not be used to automatically grow an image's length

CHANGES IN THE TOOLS:
  • fixes from Frank Cringle to update fax2tiff
  • portability fixes to tiff2bw and tiffcmp
  • tiffdump now uses the byte swapping routines in the library

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:
  • support was added for configuring the Deflate codec
  • support was added for the HTML documentation
  • codecs that are not configured for inclusion in the library are no longer compiled

CHANGES IN LIBTIFF:
  • support was added for registering new codecs external to the library and for overriding the codecs that are builtin to the library
  • emulation support for the old DataType tag was improved
  • suppport was added for the SMinSampleValue and SMaxSampleValue tags
  • the library no longer ignores TileWidth and TileLength tags whose values are not a multiple of 16 (per the spec); this permits old, improperly written, images to be read
  • the support for the Predictor tag was placed in a reusable module so that it can be shared by multiple codecs
  • experimental compression support was added for the Deflate algorithm (using the freely available zlib package)
  • a new routine, TIFFWriteBufferSetup was added a la the routine TIFFReadBufferSetup
  • the DSO version of the library is now statically linked with the JPEG and Deflate libraries; this means applications that link against the DSO do not also need to link against these ancillary libraries

CHANGES IN THE TOOLS:
  • all the tools now use common code to process compress-oriented arguments
  • tiffdump should now compile on a Macintosh with MPW

CHANGES IN THE MANUAL PAGES:
  • everything was updated

CHANGES IN THE DOCUMENTATION:
  • everything was updated

CHANGES IN CONTRIBUTED SOFTWARE:
  • contrib/dbs/xtiff was made to compile
  • contrib/mac-mpw is new support for compiling the software on a Macintosh under MPW; consult the documentation for details
  • contrib/tags is information on how to use the tag extenion facilities; consult contrib/tags/README for details

    • Niles Ritter's client tag extension hooks were added
    • a new routine TIFFCurrentDirOffset was added for applications that want to find out the file offset of a TIFF directory
    • the calculation of the number of strips in an image was corected for images with certain esoteric configurations
    • a potential memory leak (very unlikely) was plugged
    • the TIFFReadRGBAImage support was completely rewritten and new, more flexible support was added for reading images into a fixed-format raster
    • YCbCr to RGB conversion done in the TIFFReadRGBAImage support was optimized
    • a bug in JPEG support calculation of strip size was corrected
    • the LZW decoder was changed to initialize the code table to zero to lessen potential problems that arise when invalid data is decoded
    • tiffcomp.h is now aware of OS/2
    • some function prototypes in tiffio.h and tiffiop.h that contained parameter names have been changed to avoid complaints from certain compilers

    CHANGES IN THE PORTABILITY SUPPORT:
    • Makefile.in has been corrected to use the parameters chosen by the configure script

    CHANGES IN THE TOOLS:
    • fax2ps has been rewritten and moved over from the user contributed software
    • an uninitialized variable in pal2rgb has been fixed
    • ras2tiff now converts 24-bit RGB raster data so that samples are written in the proper order
    • tiff2ps has been updated to include fixes and enhancements from Alberto Accomazzi
    • tiffcp now has a -o option to select a directory by file offset
    • tiffinfo is now capable of displaying the raw undecoded image data in a file
    • tiffgt has been rewritten to use the new TIFFRGBAImage support and to handle multiple files

This * doesn't make sense since a TIFFTAG_COLORMAP is 16 bits wide and * a TIFFTAG_COLORRESPONSECURVE is tfBitsPerSample bits wide for each * channel. 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 #define XK_MISCELLANY #include #include "xtifficon.h" #define TIFF_GAMMA "2.2" /* default gamma from the TIFF 5.0 spec */ #define ROUND(x) (u_short) ((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)) ?

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. Bugs, Comments Etc: ------------------ Send all reports and suggestions to ndr@tazboy.jpl.nasa.gov (Niles Ritter). d, the standard TIFFGetField() and TIFFSetField routines may be used as before.
