grainy PS output

[Robert Urban]

Hello,

I'm trying to save an image as PostScript or EPS.  After having flattened it
and writing to a file, I view the new file using ghostscript.  The result
is always rotten-looking, at though it had somehow been dithered.

What can I do to get rid of this dithered look?

thanks,

Rob Urban

that's because ghostscript does exactly that, as it simulates a
printer. Try png or ppm output for ghostscript and it will improve. Or
print it, as this is what postscript was designed for.

postscript is not really a lossless image file format

don't use postscript to view your images. at least don't use the x11
driver of ghostscript.
