- Hi!
- All you smart people out there. Happy Holidays!
-
- Here is the problem I am facing:
- I have an image in a window, specified by a mask. The image gets
- tinted in the masked area, rapidly. I modify the colormap to affect the
- tinting, rapidly, however it updates the whole window.
- Is there anyway to achieve this effect, such that the masked region
- is only affected? Can it be done using multiple colormaps, and transparent
- window's (windows with transparent background's)? If so, how can one create a
- transparent window?
- -amit.
