image contrast, bias a la DS9 [message #70596]

Hi all,

The image display/processing program DS9 has a feature where you can
interactively adjust the colormap of the image by dragging the mouse;
this changes the colormap's "contrast" (between 0 and 10) and
"bias" (between 0 and 1). I'd like to be able to reproduce that kind
of adjustment in IDL (not interactively - I want to be able to apply
the same adjustments to a number of images), but I'm not sure exactly
what it is they're doing. Can anyone give me guidance?

Thanks!
