I have found that sending large bitmaps to my PostScript printer is one of my
biggest bottlenecks. I read in the 'green' book that compressing a bitmap
first and decompressing it in the data acquisition procedure could save some
time. The green book says ...
   "This may drastically reduce transmission time, but it is quite
   difficult to make the procedure fast enough to realize a net gain in
   overall evaluation time."

Has anybody written such a procedure? I would like to try it out on my sample
data to see if it would gain me anything.
   Any code or ideas would be appreciated.
