Christopher Myers asks:
| OK, I've read and reread the archives, googled for a while, and I still

| Can someone please tell me how to convert a .ps to a .gif?
|
| I'm running RedHat Linux 7.1, which of course has gs installed.
Here's the script that I use. Note that it takes a list of ps file
names on the command line, with or without the .ps suffix, or with
.eps as a suffix, and produces the corresponding .gif file. You'll
want to experiment with the resulution.
This also calls pnmcrop and ppmtogif, but you probably have them
installed, too. And the LD_LIBRARY_PATH may need changing.
#!/usr/bin/perl -w
#
# ps2gif [resolution] file...
#
# Convert a postscript file to GIF, using the gs (GhostScript) command. The
# resolution defaults to 100, which is a readable compromise for most
# screens. The files should be postscript files. You can omit a .ps suffix
# and we'll assume it.
