Folks,
I took the program and data described in this article
(available from the article):
http://www.idlcoyote.com/ng_tips/imgmap.php
I changed the map projection from "Equirectangular" to
"Robinson" and ran the program again. Perfect!
At least it was perfect until I tried to save the
visualization as a PostScript file. Then there is
a black rectangle that seems to be positioned behind
the map projection. It doesn't show at all on the
display, but clearly shows (and won't go away!) on
the PostScript file. Presumably I didn't see the
rectangle before because the equirectangular
projection covers it up.
Any ideas for getting around yet one more problem
in IDL 8 graphics? I mean, besides adopting the
equirectangular projection as my favorite. :-)
Cheers,
David
