Actually, this bit down here, won't work on OpenGL ES as glGetTexImage doesn't exist there. You would need to bind the texture into a framebuffer object and glReadPixels it. If you're only deploying to desktop GL, this will not be a problem, but if you are targeting ES, including Windows/ANGLE, this code needs to be updated. cheers, Gunnar www.sletta.org _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
