Can anyone tell me how (if this is possible) to do it? I would like for a postscript program to ascertain which pixels have been set and which have not in the raster memory of the printer its running on. Is there ANY postscript construct which tells you whether pixel (x,y) in the raster grid is set? I realize this is somewhat machine dependent -- are there any postscript printers which can do this? I'm trying to make some high quality color slides, and one crazy idea I have is to do it in postscript, and have the postscript program transmit (run encoded) the raster that's formed, without printing it. (And no, reverse engineering of fonts is not my goal, although this is what gave me the idea...). Thanks, David Baraff deb@svax.cs.cornell.edu
