Forgive me if this is a FAQ or related to one. I wasn't able to find
a reference anywhere.

I've got this 1024 x 864 screen dump that I'm converting into color
Postscript. I've been successful in translating it into a printable file.

The problem arises in that there are only about 12 colors in the screen
image, so I'm creating a five Meg file when I could actually be creating
a much smaller file. I'm sure that the processing and printing would be
significantly faster if I could use four bits/pixel.

So is there some easy way to do "paletted" or mapped color? I've been
unsuccessful using single-nybble color in the image map, but maybe that's
a result of not knowing the right way to do it. Alternatively, is there
some way to get around the ascii expansion of the bitmap?

The target printer is a Tektronics Phaser III that supports Postscript
Level II.

Thanks!
