The third release of the Portable Bitmap package is ready for FTPing
from expo.lcs.mit.edu:contrib/pbm.tar.Z.
Answers to some frequently asked questions:
- The decimal address of expo is 18.30.0.212.
- Please avoid ftp'ing from expo.lcs.mit.edu in between the hours of
9am and 6pm east coast, USA time.
- There may be other places to FTP it from, but I don't know of them.
In particular, you can't FTP it from lbl-rtsg. Don't even try.
- Don't forget to set binary mode when you do the FTP.
- Pbmtorast and rasttopbm depend on Sun's pixrect library, and will
compile only on suns.
- Currently there is no way to get the package other than FTP. However,
if comp.sources.misc ever gets going again, perhaps PBM will get
distributed there. (I have sent mail to the moderator about it, and
have received no reply.)
Appended is the README for PBM. It includes a list of the major enhancements
in this version.

Portable Bitmap Toolkit
Distribution of 31aug88
Previous distribution 04apr88
Included are a number of programs for converting various bitmap formats
to and from a portable format; plus some tools for manipulating the
portable bitmaps.
Major changes since the previous distribution:
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'.
Plus various minor bug fixes and enhancements.
Files in this distribution:

pbmtrnspos.c transpose a portable bitmap x for y
libpbm.c a few utility routines
pbm.h header file for libpbm
macp.h definitions for MacPaint files
x10wd.h definitions for X10 window dumps
x11wd.h definitions for X11 window dumps
bmaliases csh script to make aliases for converting formats
*.1 manual entries for all of the tools
pbm.5 manual entry for the pbm format
bitreverse.h useful include file
Unpack the files, edit Makefile and change the options to suit,
make, and enjoy! Note that if you're not on a Sun, you won't be
able to compile rasttopbm and pbmtorast.
I've tested this stuff under 4.2 BSD, 4.3 BSD, and System V rel 2,
and on both Suns and Vaxen. Nevertheless, I'm sure bugs remain.
Feedback is welcome - send bug reports, enhancements, checks, money
orders, etc. to the addresses below.
