This works fine for rendering an image on Windows. When rendering the image on a mobile devices (in my case a Samsung Galaxy Tablet) the colors are shiftet. To be precise red and blue are swaped. I copied this image from the tablet to windows and the image has still shifted colors. Thus it seems to be a problem in the rendering process.

Using an image with alpha channel is important. I can't switch to a format whithout alpha.
I tried some other alpha channel formats, e.g. Format_ARGB32. But the color problem still occurs.

I changed the program such that it swaps red/blue and the picture rendered on the tablet looks fine (of course now rendering on windows results in wrong colors). But this is not a good solution, since I dont now if this behavior is on every tablet the same.

Is there something known about this color shifts on mobile devices? Do you have any suggestions?

Thanks a lot,

Jörg
