What version of IDL is this?
Up until IDL 7, I think, IDL had this insane notion
on some machines (Windows, for sure) that when you
were in indexed color mode ALL images should pass though
the color table vectors, even images that already had
their colors specified directly!!
Naturally, this is NOT what anyone, anywhere wanted to
do. This has since been fixed, but it still makes it
difficult to display images correctly. It is one reason
why I haven't used a TV command since about 1998. TVImage
or ImgDisp is your friend, here, Nata!
Cheers,
David
