But it seems that I can't do this in ENVI. Say my image is 512*512, I
can only export it as a 512*512 image, I can't change the dimentions.
I know a little bit IDL (direct graphics), so I'm thinking maybe I
could try to do a program. Is it possible to use different colors or
color tables to display different parts of an image? My image includes
3 parts: ocean (=999), land(=900), ROIs on land (=0~100). I'd like my
ocean to be white, land to be yellow, and ROIs to be displayed using
the Blue-red color table. I've been trying for 3 hours with no luck.
Could you give me some hints or at least tell me is it possible with
IDL direct graphics?

Thanks again,
Jenny
