[comp.lang.postscript] Pixel data

deb@svax.cs.cornell.edu (David Baraff) (04/26/89)

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,
