hi Dave, > The only thing which (I think) has changed is the way that the texture > is read in - so is this not expected behaviour? Or are you saying that i'm not sure, because i didn't have time to think this over properly yet. i would expect that the first pdata is connected to the first pixel of the image, which is not the case at the moment. it is connected to the first pixel of the image's last row. i think this is caused by the changed png reading order.
i don't think the pdata could be flipped, because right after loading the image a (pixels-upload) could flip the image, which is also wrong in my opinion, but i might have missing something. best, gabor
