SUMMARY: Pixrect to GIF (or similar)

From: Steve Simmons (
Date: Sat Jan 29 1994 - 19:32:38 CST

The overwhelming suggestion was to use pbmplus, a portable bitmap
manipulator. Ted Nolan was kind enough to point out that it's available
for anon ftp from in /pub/X11/contrib/pbmplus10dec91.tar.Z.
Other suggestions include fbm, xv, Image Alchemy, Image Magic, and a
raft of other things. Gene Rackow forwarded a file from the netpbm
distribution which practically stands alone as a summary. One other
suggestion, Image Alchemy, is included below the file Gene forwarded.
