Hi klaus,
thanks for your example. I took it as a base to play around with and I've attached my result to this message.
The program simply glues 9 map tiles of 256x256 pixels together to one image and this is displayed on the screen and can be moved around with mouse/stylus/finger.
I found out that updating UI-Controls in the MouseMove event sub (like displaying the current coordinates in labels) slows down everything a bit. After removing the labels displaying the coordinates the movement with stylus/finger is much smoother. Compiled with the optimizer the speed is really smooth now.
I think this is a base I can work on for my program. Now I have a better understanding of how Image handling and manipulation works in b4ppc.
Thanks very much for your help. This forum is really invaluable.
Markus
