I want to ask a question about color postscript and bitmap images
is it possible to create bitmap images using 8 bits images instead
of 24-bits. So far I only know hows to do 24-bits (16.7 million colors)
and I want to reduce it to 8-bits (256 colors) but not in 256 shades of
gray. If anybody has a an answer to this send me e-mail. Also code that
translate color GIF pictures into color postscript would do fine.
Thanx for any responce,

The PPM (Portable PixMap) format is able to write to Color PS, and it will read from GIF and many other formats. I don't know where the best place to get this program is, but it's wonderful, and it should be pretty easy to find. Best of luck... - Chris Ross cross@eng.umd.edu
