Changes since the expo.lcs.mit.edu FTP release 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'.
