I've created an RGB image from a data file, but now I want to be able to
draw things on it which result from user interaction. How can I do this?
I tried overlaying a pixmap on top of the RGB image, but it just covers
it completely... apparently pixmaps arent transparent. :) Any ideas?
When you draw the GdkPixmap over the GdkWindow (GdkWindow
because that's where you 'put' your GDB RGB buffer first)
and then use a GdkGC with a clip mask created from the
GdkPixmap's mask (the GdkBitmap). This will make the
transparent parts of the GdkPixmap, transparent.
