OK, just so I understand. I can't do anything about saving
the PostScript file from the graphics window. If I understand
correctly, it *always* does BITMAP=0. But, I could,
presumably, use the SAVE method on the visualization
object (assuming I can get it out of my program!) and
save it that way with BITMAP=1.

Is that the gist of it?

Cheers,

David

P.S. And I presume, since I have to do this by hand
anyway, that this is where I would make the PostScript
output actually fit on a sheet of paper. Is that correct?
If so, how would I do that?
