distributed):
1. Corrected the XYZ -> RGB transformation;
2. Eliminated the -interpwp option, a fudge which had been
necessitated by the incorrect XYZ -> RGB transformation;
3. Added a Gamma correction, missing in the original;
4. Added the option to plot u' v' chromaticity instead of x y;

Eliminate pgm_pbmmaxval, ppm_pbmmaxval, and pnm_pbmmaxval
from libpgm, libppm, and libpnm. 'maxval' argument to
pgm_readpgmrow() and ppm_readppmrow() already accomplishes
this. pnm_readpnmrow() changed to do same. external data
symbols like this do not work with Mingw.
various changes to accomodate Mingw (native Windows)

pstopnm: Remove gratuitous 5% margin. Add -equalpixels,
-imageheight, and -imagewidth options.
pnmtopng: Read only one row at a time, not the whole image,
into memory. Do multiple passes through the (hopefully
fully cached) file. This saves memory because pnmtopng's
internal format may use 96 times as much space per pixel
as the file.
libpbm: Add pm_openr_seekable(), pm_seek(), pm_tell().
libppm: Add ppm_computecolorhash2(), ppm_computecolorhist2().
configure: fix bug with Solaris/Sun compiler.

for automatic generation of pm_config.h. Move pm_*()
subroutines from libpbm1.c to new libpm.c for clarity.
Remove malloc.h from 411toppm. malloc is included by
pm_config.h, in platform-dependent way.
01.05.13 BJH Release 9.14
fix bug in shhopt causing wild branches.
winicontoppm: Make alpha mask ("and") output PBM instead
of PPM; correct sense so white is opaque, black transparent.

xpmtoppm: Add --alphaout option
ppmtogif: Add "=" to -transparent option to specify exact
color.
configure: change /bin/perl to /usr/bin/perl. Red Hat Linux
doesn't have /bin/perl.

usually dynamically linked now, so it's the version of
libpbm, not the program itself.
pbmtext: add -space option.
asciitopgm: fix crash due to memcpy that should be memset.
Thanks Philipp Knirsch <pknirsch@redhat.com>.
pktopbm: fix numerous bugs. Copied from Red Hat. By
jcn <janneke@gnu.org> 1998.09.22.
pstopnm.csh: fix bomb when xres=yres. This program is

<nalin@redhat.com> 2000.02.14.
pnmtotiff: Make photometric for G3/G4 fax MINISWHITE
instead of MINISBLACK. Add -minisblack option. Thanks

00.04.15 BJH Release 9.0
Add the 16-bit-per-sample format for maxval > 255.
Change size of samples in the library interface from 8
bits to 32 bits. Library write routines now create the
new 16 bit format instead of plain format when you

convert to PNM from a >8 bit input generate it instead
of failing or normalizing. Make pnmdepth generate it.
pnm_readpnminit(), etc. fails if you request a maxval >
65535 and not 'forceplain'. It used to generate plain
format in that case, but you couldn't actually specify
a sample value > 255.

Computing Research Center.
add ppmcolormask - creates a mask of areas of a certain
color in an image.

Add ppmtompeg, adapted from Berkeley's mpeg_encode.
Add eyuvtoppm and ppmtoeyuv, and vidtoppm, from Berkeley
mpeg tools.
Add ppmfade, adapted from Wesley C. Barris' pbmfade.
Add ability to extract the alpha channel to tifftopnm,
tgatoppm, and ximtoppm. (It's already in pngtoppm,
and still missing from ilbmtoppm).
pnmtotiff: Change default compression to none, due to
removal of LZW capability from Tiff library.
Make merge build use symbolic links instead of hard links.
Include dependent libraries in the link of the
libraries. This is necessary on some systems, and a
good idea on others.
Use strerror() instead of sys_errlist[] everywhere. If
some systems do not have the former, we need to do some
work, because strerror() was already used in some
places. We do have a report of a BeOS system with no
sys_errlist[].
00.03.24 BJH Release 8.3

Added a global -version flag.
Added bunches of statics and prototypes. Now compiles with zero
warnings under gcc -ansi -pedantic.
Changed #ifdef __STDC__ to #if __STDC__, since some non-compliant
compilers define it as 0.
Changed pm_message and pm_error to be varargs routines. Added a
portable version of vfprintf for those systems which don't have it.
Removed the option of not compiling the pgm and ppm parts. Very few
people used it, and it added amazing complexity to the pnm programs,
turning them into maintenance nightmares.
Merged pbmpaste into pnmpaste.
Merged pgmtops and ppmtops into pnmtops.
Added auto-scaling and dpi / page size flags to pnmtops.
Changed the interpretation of bits in pbmlife to conform with other

pbmtoxwd and ppmtoxwd into pnmtoxwd.
Promoted some filters:

Added $(MAKE) stuff to Makefile.
Changed pnmsmooth from a csh script to a sh script.
Made macro use in pbmtox10bm and pbmtoxbm more portable.
Moved compataliases to compat.csh, and added compat.ksh.
Made ppmtoilbm less Amiga-specific.
Added -headerskip and -rowskip flags to rawtopgm.
Enhanced rasttopnm to interpret 8-bit rasters with no colormap as grayscale.
Changed sscanf %g to %f - some systems can't handle %g on input.
Added -expand flag to pbmmask.
Speedup to pnmflip - don't buffer if possible.
Added color-name-to-value routine to ppm - uses X11's rgb.txt if present.
Updated Imakefile support to reflect X.V11R4.
Removed picttopbm.
Improved pnmcut argument syntax so that negative coords work like pnmpaste.
Added "magic" file, for use with the "file" program.
40% speedup for pgmnorm from Robert Stockton (rgs@cs.cmu.edu).
Fixed long-standing bug involving colormaps on SPARCstations when
compiled with gcc -- had to do with passing structs by value.
Removed the -x flag from pnmtorast -- it's not really needed.
Fixed subtle bug in the pnm reading code that caused pnmcat to blow
it on images that differed greatly in width or height.
New version of giftoppm that handles the GIF89a standard, and doesn't
use fseek.
Fixed fitstopgm to handle three-axis images, such as the Hubble pix.
Xwdtopnm and pnmtoxwd finally handle byte-order properly.
Added -xysize flag to pnmscale.
Added conditional ANSI function prototypes to library routines.
Added -noantialias flag to pnmrotate and pnmshear.
Removed the TIPS file. No one ever sent in any new tips, so I just
moved the few I had into the relevant man pages. That's probably
where they belonged in the first place.
Added justification flags to pnmcat.
Added -map flag to ppmquant - user-specifiable colormap. Also, the
Floyd-Steinberg error diffusion finally works right.
Added -map flag to pgmtoppm.
Added DirectColor support to xwdtopnm and pnmtoxwd.
Speedup to pgmtolj from Arthur David Olson: avoid sending whitespace.
Fix to pbmtogo from Bo Thide': 2D compression now works.
Patch 1 to the X.V11R4 / comp.sources.misc distribution of 22nov89:
Fixed bug in pgmtops -rle.
Changes since the alt.sources distribution of 13sep89:
Small corrections to ppmtorast, pgmtops.
Moved pbm/tifftopbm to pgm/tifftopgm - it now handles grayscale TIFF files.
Fixed tifftopgm to handle non-native byte order.
Changes to tifftopgm to handle bogus AppleScan TIFF files, to have
better command syntax, and to use stdio.
Optimizations to xbmtopbm, pbmtoxbm, and pbmtox10bm, courtesy of
Juha Sarlin, to make them go about three times as fast.
Optimization to pgmtops and ppmtops to make them go three times as fast.
Optimization to pnmcrop.
Added PBMPLUS_BROKENPUTC defines in pbmplus.h to handle systems (such as
ULTRIX) which have broken putc() macros.
Rewrote ppmscale, pnmcat, and pgmhist to operate line-by-line, instead
of reading in the whole image.
Rewrote pnmflip to keep only one copy of the image in memory.
Added pgmtofits, courtesy of Wilson H. Bent, plus bugfixes to fitstopgm
and a patch to giftoppm to handle black&white GIF files.
Added picttopbm and rawtopgm.
Fixes to xwdtoppm and ppmtoxwd so they compile with SunOS cc as well as gcc.
Another small change to ppmtoxwd having to do with colormap size.
Changed macptopbm's -headersize flag to be -extraskip.
Changed tgatoppm to read color values as BGRA instead of ARGB; the Targa
documentation is apparently wrong about the order.
Some changes to the Makefiles, partially to work around bugs in gnumake.
Got g3topbm working, and added pbmtog3, courtesy of Paul Haeberli.
Added some pixrect work-alike code so that rasttopbm, pbmtorast, rasttoppm,
and ppmtorast can be used on non-Sun systems. This also provides a
final solution to the persistent byte- and bit-order problems on 386's.
Moved the SYSV-checking #ifdefs to *after* the include of pbm.h, which
defines SYSV.
Made all the #else's and #endif's ANSI-compliant.
Added manual pages for libpbm, libpgm, libppm, and libpnm, courtesy
of Tony Hansen.
Changed man page installation so that pages from different sections
can go in different directories.
Fixed Imakefiles.
Changes since the expo.lcs.mit.edu FTP distribution of 06sep89:
Added #ifdefs to pnm/libpnm3.c to allow the PBM-PNM-only configuration.
Small corrections to TIPS, pnm/Makefile, pnm/Imakefile, ppm/ppmrotate.1,
ppm/ppmshear.1, ppm/ppmtoilbm.c, pbm/xwdtopbm.c, ppm/xwdtoppm.c,
ppm/ppmtoxwd.c, ppm/ppmtoxwd.1, pbm/x11wd.h.
Changes since the comp.sources.misc distribution of 31oct88:
Added pbmreduce, pbmlife, pbmmask, and pbmupc.
Added gemtopbm, tifftopbm, pcxtopbm, pbmtogo, mgrtopbm, pbmtomgr,
cmuwmtopbm, pbmtocmuwm, g3topbm, and pbmtobg.
Minor bugfix to pbmtolj.
Slight restructuring of most of the programs to use vastly less memory.
Various other minor optimizations.
Fixed pbmtorast and rasttopbm to handle byte-swapped big-endian 386 boxes.
Slight changes to argument syntax of pbmcrop, pbmmake, pbmreduce.
Moved to the new PGM package: pbmtops (which now produces Conforming PS).
Moved to the new PPM package: giftopbm.
Moved to the new PNM package: pbmcrop pbmcut pbmenlarge pbminvert.
Consolidated into a single pnmflip tool: pbmfliplr pbmfliptb pbmtrnspos.
Consolidated into a single pnmcat tool: pbmcatlr pbmcattb.
Added compataliases script for upward compatability with changed tools.
Removed xxxtopbm.
Added a -headersize flag to macptopbm, to help get around annoying
problems in MacPaint file format.
Added the RAWBITS compilation-time option, to use a more compact and
much faster (but less portable) external format.
Removed the CBM format - use compress(1) and / or RAWBITS instead.
Pbmpaste (and the new pnmpaste) now accepts negative x and y coords,
which are interpreted relative to the right and bottom sides.
Changed all programs to accept a "-" file argument as meaning standard
input.
Removed pbmtox10wd, since it was never very useful (X10 doesn't have xwud).
Added Imakefiles, for X11 types to use.
Changes since the X.V11R3 distribution of 31aug88:
The cbm format has been revised to support run-length encoding.
Pbmtops now does run-length encoding.
Major changes since the X.V11R2 distribution of 28mar88:
The pbm format now has a "magic number".
New conversion filters: brushtopbm, giftopbm, pbmtolj, pbmtomacp,
pbmtoxwd, and pbmtox10wd.
Icontopbm converter has a better parser -- it knows to skip over
any extraneous comments at the beginning of the icon file.
Pbmtops generates a different PostScript wrapper program -- it should
handle huge bitmaps better.
Xwdtopbm now handles byte-swapping correctly.
Pbmmake takes a flag to specify the color of the new bitmap.
Pbmpaste now implements 'or', 'and', and 'xor' operations as well
as the default 'replace'.
