I'm not above blaming IDL for all the world's problems
occasionally, but in this case I would have to say it's
probably not IDL's fault.

I would say that IDL does (mostly) work the same on
all platforms in 24-bit True Color. (I do wish
someone would fix the annoying behavior of running
24-bit images through the color tables when Device,
Decomposed=0 on Windows platforms, however. That is
MOST annoying and doesn't work that way on UNIX
machines.) But I don't think there is a general
agreement on what Direct Color really means.

I don't know anyone who can get it to work from
one machine to another, let alone from one flavor
of UNIX to another. And it is not even available
in the PC world, so why worry about it. :-)

Yep. One reason I *never* use the XOR method. I'm
a tried-and-true Device Copy man, myself.

Cheers,

David
