Compressed Postscript bitmat format.

[Francois Felix INGRAND <felix@WARBUCKS.AI.SRI.COM>]

I am writing a report and I am including some hardcopies of the Lisp
Machine screen (Postscript format) in it. To avoid any cutting/pasting,
I include the "postscript file" in my document (using the \special
command with LaTeX/dvips).

Unfortunately, each screen dump is approximately 220 K...
Considering that I will have 60 screen dumps... It makes 12 Mega of
pictures for this report... (that I have to keep under postscript
format for inclusion)

I had a quick look to the format used in this screen dump, and it
looks like it is not compressed at all. When I run it thru "compress"
I get a 91.08% compression rate (after all, these screens are almost white).

I was just wondering if anybody have already written, in lisp for the
Lisp Machine side, and in postscript for the printer side, a small
"compressor".

Thanks in advance,

Felix
