I was wondering if it would be possible to check individual pixels on an EGLsurface (using opengles1.1) for a certain colour. This would done before swapping back and fron buffers of the surface.
edit: Possible use eglcopybuffer to a pixmap maybe??
could i use glreadpixels? (along with glreadbuffer but then it would need to be read BEFORE swapping buffers)

Hmm I've never tried this myself - could be best to query an OpenGL-specific forum for something like this; It may be expensive to do at each frame but I don't see why is would not be possible;
