Hello,Could you give me some help on the following problem --
I want to use different color tables to display different parts of an
image. My image (intarr(700*700) includes 3 parts: ocean (=999),
land(=900), several 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 sometime with no luck. Could you give me some
hints or at least tell me is it possible with IDL direct graphics?

Thank you in advance,
Jenny
