Well, you and everyone else. For a long while IDL
was changing the way color was handled with every release.
It seems to have settled down lately, but I *still* get
results I don't fully understand from time to time when
I am on the road and away from my own fully-debugged setup. :-)
Cheers,
David

Followup:
The Z-buffer works as advertised (8-bit indexed color). However, the
behavior of using WINDOW,/PIXMAP appears to have changed. This now
appears to always produce a 24-bit buffer. I have several routines that
worked recently that returned indexed data from PIXMAP windows. I am
confused, which is news to no one.
