// These are the possible colormap types.
// if it's in RGB format, the map is made up of three byte arrays
// (red, green, then blue) that are each 1/3 of the colormap length.

#define RMT_NONE		0	// maplength is expected to be 0
#define RMT_EQUAL_RGB	1	// red[maplength/3], green[maplength/3], blue[maplength/3]
#define RMT_RAW			2	// Raw colormap
#define RESC			128 // Run-length encoding escape character

// ----- NOTES -----
// Each line of the image is rounded out to a multiple of 16 bits.
// This corresponds to the rounding convention used by the memory pixrect
// package (/usr/include/pixrect/memvar.h) of the SunWindows system.
// The ras_encoding field (always set to 0 by Sun's supported software)
// was renamed to ras_length in release 2.0.  As a result, rasterfiles
// of type 0 generated by the old software claim to have 0 length; for
// compatibility, code reading rasterfiles must be prepared to compute the
// TRUE length from the width, height, and depth fields.

file.  The maximum size of a COM block is 64K, but you can have as many of
them as you like in one JPEG file.

We provide two utility programs to display COM block contents and add COM
blocks to a JPEG file.

rdjpgcom searches a JPEG file and prints the contents of any COM blocks on
standard output.  The command line syntax is
	rdjpgcom [-raw] [-verbose] [inputfilename]
The switch "-raw" (or just "-r") causes rdjpgcom to also output non-printable
characters in comments, which are normally escaped for security reasons.
The switch "-verbose" (or just "-v") causes rdjpgcom to also display the JPEG
image dimensions.  If you omit the input file name from the command line,
the JPEG file is read from standard input.  (This may not work on some
operating systems, if binary data can't be read from stdin.)

wrjpgcom adds a COM block, containing text you provide, to a JPEG file.
Ordinarily, the COM block is added after any existing COM blocks, but you
can delete the old COM blocks if you wish.  wrjpgcom produces a new JPEG
file; it does not modify the input file.  DO NOT try to overwrite the input
file by directing wrjpgcom's output back into it; on most systems this will

src/Source/LibTIFF4/ChangeLog  view on Meta::CPAN

	* configure.ac: Applied patch by Brad Smith to improve pkg-config
	static linking by adding -lm to Libs.private when needed.

2013-03-05  Tom Lane  <tgl@sss.pgh.pa.us>

	* html/man/tiff2ps.1.html, html/man/tiffcp.1.html,
 	html/man/tiffdither.1.html, man/tiff2ps.1, man/tiffcp.1,
 	man/tiffdither.1, tools/tiff2ps.c, tools/tiffcp.c,
 	tools/tiffdither.c: Sync tool usage printouts and man pages with
 	reality (quite a few options had escaped being documented in one
 	or both places).  Per an old report from Miroslav Vadkerti.

2013-01-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tools/tiff2ps.c:Fix bug in auto rotate option code. Once a
	rotation angle was set by the auto rotate check, it was retained
	for all pages that followed instead ofa being retested for each
	page.  Patch by Richard Nolde.
