Try pix_snap to grab the backbuffer and return it as an RGBA image.

OK, now I have: [gemhead] [translateXYZ] [pix_snap] [pix_data] [cube] And it still doesnt work. Could you possably send me a simple patch that tells me, for example, what color the pixel in the middle of the gem window is?
well, working with [pix_snap] is somewhat specific. of course you have to send a "snap" message to [pix_snap] to do the actual image-grabbing. make sure you send it at the right moment in time (see the help-patches in gem/examples/02.advanced/) so that the backbuffer is filled with something.
you don't need to have [pix_snap] and [cube] in one gemlist (but of course it is valid) again: make sure that something is drawn into the backbuffer before you "snap" it. (probably [cube] should be somewhere before [pix_snap]...)
Also, is there a better gem manual than the one at gem.iem.at/manual?
well, i think the example and reference patches are quite ok...
