In the past, there have been many requests for compressing
bitmaps for transmission to postscript printers.  The general
opinion is that the overhead for the interpreter to decompress the
bit streams, is such to make this unfeasable.

I may have the cure for that.  If someone has a nice SHORT compress/decompress
routine written in 'C' or postscript and will email it to me, I'll see about
converting it to cexec stuff.  I'd prefer a short simple 'C' routine that
does rll decoding, as the ultimate target will be 'C', though if you have
a simple one in postscript, I'll convert to 'C' and then to cexec.  This is
sort of an experiment.  If it works, I'll post the routine to the net.  I'll
also need a short encoded file to test the 'C' code against.

I most certainly will need both ends (compress and uncompress).  Perhaps
if someone has a CCIT group III fax compression and decompression routine
that they can email we can try that also.  That would have some distinct
advantages..


Cheers
Woody
