The long-rumored color extensions to the Portable BitMap package are
now ready for initial distribution. This is the first new version since
31oct88, and the package has grown by about a factor of four. It now
includes 72 programs and 197 files. Appended to this announcement is
a list of the formats supported.
The package is broken up into four parts. First is PBM, for bitmaps (1
bit per pixel). Then there is PGM, for grayscale images. Next is PPM,
for full-color images. Last, there is PNM, which does content-independent
manipulations on any of the three formats.
Three other important changes are that the programs use much less memory,
run much faster, and generate much smaller temp files (upward compatibly).
My distribution plan is: first, via FTP as:
expo.lcs.mit.edu:contrib/pbmplus.tar.Z
For those who still don't have name resolvers, the decimal address of
expo is 18.30.0.212. Don't forget to set binary mode when you retrieve
it, and please don't FTP during working hours (9 am to 6 pm eastern
time). Then, after waiting a few days for any obvious problems to
surface, I'll post it to alt.sources. Finally, after a suitable
beta-test period, I'll post it to whatever moderated sources group is
working (currently comp.sources.misc). That version will also show up
on expo, and perhaps even in the X.V11R4 release.
There is currently one known bug: the g3topbm FAX-reader does not work.
I hope to get it working soon, but I've been sitting on this package for
so long that I decided to release it anyway.
Enjoy.

As promised, PBMPLUS has now been posted to alt.sources. The changes
since the FTP version 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.
This new version has also been put on expo, replacing the 06sep89 version.
