Ah, yes. I remember from your class... Say, could I rent that bunny suit you
wore in class?
Thanks,

This way, you can probably pass "under the little used
"Most Obsequious to the Judges" category. :-) " - D.F.

You can try to reduce the focus or contrast on the video projector to
the point where the characters can be seen but can be barely discerned.
This way the audience will think there is a technical problem and relief
their frustration by blaming the cheap projector or a tech guy, and show
no inquisitive interest regarding the character set used for contouring.
Hope this helps.
Cheers,
Pavel

All I can say, Ben, is that this is why you are *taking* the test and
not *giving* it. Think of it as a Zen koan and you will have
more luck. :-)

Yes, there is a special type of incense, but you can't purchase
it until you pass the exam. It's sort of the IDL version of the
Catch-22, I guess.
What you could do is introduce your presentation as having
been done in Dr. IDL. That would impress some people, probably.
Failing that, you could make your display screen VERY big
and try true-type fonts. I've sometimes tried (with varying
amounts of success) to make a Z-buffer window 4X times the
size of the display window, and draw with large true-type
character sizes (you have to increase the thickness of
everything else too, with this technique). Then I rebin
this huge window to about 1/4 its size for display.
As I say, I've gotten decent viewgraphics occasionally with
this technique.
Or, you could make a PostScript file with true-type fonts,
and scan these images into TIFF files, which you could
display in sequence in IDL.
Or, ....
Well, you could just do what I do. Wave your hands
quickly and draw everyone's attention away to something
other than the contour labels. This has a surprisingly
high success rate without actually solving the problem.
A real boon for programmers working by the hour. :-)
Cheers,
David
