Does anybody know how to move (slide) an image (or a portion of the image)
around in a window without using the TV command in IDL 2.4.0?
We want to develop a display where new real-time image data enters on the
right side and old image data scrolls to the left. This can be done by
building a loop that shifts the whole image array, replaces the profile
on the right and reTVs the whole image to the window, but of course it
takes a lot of time. We hope there is a way to just move the data in the
window by a certain amount without having to shift and reTV whole image.
Any ideas would be greatly appreciated. Thanks.
