First of all, "rotated hardware fonts" is an oxymoron.
It's not going to happen. (Unless your "hardware" happens
to be PostScript, then you might have a chance.)
What you can get are true-type fonts, which will *look*
like hardware fonts and can be rotated. For example,
like this:
IDL> Shade_Surf, dist(20), ZTitle='Meters', YTitle='Latitude', $
XTitle='Longitude', Font=1, Charsize=3
Sometimes the true-type fonts don't look as nice as
you would hope on the display, although they do look
beautiful in hardcopy output.
If display aesthetics are important, you can try a trick
like drawing your graphic in the Z-graphics buffer at
4-5 times the resolution, then rebining it for the
display. (I include an example of this below.)
Unfortunately, this trick is a little bit too color
dependent for my taste. I haven't had the time to
investigate exactly why that is, but if you can get
away with black or white output, it does a nice
job.
Cheers,
David
