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, Richard Lefebvre email rick@cfdws5.concordia.ca or sotbill@vax2.concordia.ca Phone (514)848-8601

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
