I know this has been axed before, but how can you get predictable results from pix_snap?
it seems to me that pix_snap will only take pixel values from the background color - the color you set when you send a |color r g b ( message to gemwin.
I've tried setting the gemhead render order, and I've tried setting the gemwin buffer to 1 or 2.
when I set the gemwin buffer to 1, I _sometimes_ can see that it is outputing pixel values from the screen, when I set the buffer to 2, I can only see that it is reading the backround color info.
attatched is a test patch.
any thoughts?
thanks -august.
The render order is very critical for pix_snap and pix_snap2tex. To take a picture of the complete scene, make sure pix_snap is the last thing rendered. Use fixed gemhead values for this.

Sorry, I just looked at the patch. You need render_trigger. Freely hitting [snap( usually won't do.
