Byooteeful output now. On ya. I would've checked your book up front but it's the one text
I have trouble keeping on my shelf. :o( I have 5 Fortran95 books and 1 Fortran2003 book
that I can't seem to get *anyone* to read. Sigh.
As an aside, I use shade_surf a lot and I don't ever recall not getting nice looking
output first pop - I've never needed to use the pixels keyword before. But all is well now
- and just in time for my 1 o'clock meeting! Phewph!
shanx,
paulv

Try the PIXELS keyword, e.g.,
shade_surf, z, x, y, pixels=1000
The PIXELS keyword sets the maximum size of the image rendered by
SHADE_SURF. This keyword is honored on devices with scaleable pixels,
(notably the PS and CGM devices), and is ignored otherwise. See p. 279
of my book for more details.
Cheers,
Liam.

Now, now...
What exactly do you mean by "shade_surf image"? The
actual shaded surface, or the image returned by the IMAGE
keyword? Did you execute the Shade_Surf command while
in the PostScript device? What command are you using
to "output to a PS file"?
Cheers,
David
