Hey all,
We are trying to get individual pixel data from a PVR texture in order to see if a user has touched a part of a sprite that is transparent or not. We know how to do it with a PNG image since it is supported by UIImage, but have had no luck with PVR's.
We tried to draw the texture to an offscreen buffer and then use glreadPixels to get the pixel data at the touch location, but that was very problematic. Anyone have any advice or have tackled something like this before?
Thanks,
-Andrew
