Hey Jack,
I realized I forgot to mention the image can't be in the gemwin. That is I render a bunch of stuff into a framebuffer, and add it to the video, all without ever sending it to the gemwin.
This patch should be ok.
AFAIK pix_snap will only snap the gemwin, not the gemframebuffer itself? Or is this wrong?
Wrong, [pix_snap] snap 'things' rendered before it receive a bang. So you can see all your scene in the gemwin and snap only one part. This is the same with [gemframebuffer]. You can snap only one part of the [gemframebuffer], that depend of the order of the rendering. Then you don't snap 'things' in the gemwin.
That is I need to get the texture off the gfx card, back into pix_ domain, *without* using the gemwin to do it.
You can share the pix_ with [pix_share_write] and [pix_share_read]. As Chris says, it should be faster with GLSL and the work on textures, because [pix_snap] is slow. Hope it's enough clear and i didn't make a mistake ! ;) ++

Thanks for trying! .b.

Hey all,
I'm rendering data into a framebuffer, but want to be able to pix_add that texture with a live video input.
How can I get a gemframebuffer image from texture space into pix_ space???
