Hello,
I usually use GdkImlib to render pixmaps. For the following purpose
I consider it to be not optimal in matter of speed.
After displaying the rendered pixmap in a gtk_drawing_area I
have to change the RGB data of each pixel after certain rules.
The size of the pixmap will not change. Currently I change
the rgb_data of the GdkImlibImage and render a new pixmap.
How can I improve the speed, i.e. write directly into the
pixmap?
I havn't used gdk_rgb() at this time. Would it help for this
matter and are there examples for use.
Kind regards
Andreas.
