not tested, but i think that should work.

Short answer: You can't.

Slightly longer answer: You will need to draw to the backbuffer and then grab it, as suggested above, or get a 3rd party library that does this for you. I believe Indiepath has just the thing.

Theres an addon that allows you to use buffers in a usably fast way. Do a search for HighGFX module.

Or use TPixmap.
