I don't know. What kind of visual effect *did* you get?
Maybe it just needs to be scaled. Does TVSCL give you
a better effect than TV? ENVI sometimes applies some kind
of image "stretch" to the image before displaying it. Try
putting it in my XStretch program. Can you get it to look
like the image in ENVI?

IDL> XStretch, image

You can find XStretch here:

Why don't you just look up Ken Bowman there at Texas A&M
and tell him the guys on the IDL newsgroup said to spend
10 minutes with you introducing you to IDL. I'm sure
he would be pleased to do it. :-)

Cheers,

David
