I have been using IDL's shade_surf procedure to generate PostScript
output; but note this from the IDL manual:
"If the graphics output device has scalable pixels [as PostScript
does], the output image [of shade_surf] is scaled so that its
largest dimension is less than or equal to 512."
How do I override this? A 512x512 image printed on a high-quality
color PostScript printer doesn't look very great. I'd like to force
shade_surf to generate, say, a 2048x2048 image.
Shade_surf has an option whereby it places the resulting shaded-surface
image into an array (which presumably could later be send to a PostScript
file), but this may not work either---since shade_surf also draws the axes
and annotation (separately, I believe, from the shaded-surface image
itself), these would have to be written separately to the PostScript file.
And then the image would have to be written such that it was positioned
and scaled *exactly* right, in order to fit the axes. This sounds like
more trouble than it's worth.
If anybody can help out on this matter, please send e-mail to
staley@goshawk.lanl.gov or staley@math.arizona.edu. Thanks.

Can you post any results since I'm looking for an answer for the same question.
Thanks in advance.
