[Bf-committers] game-engine screenshots with occluded windows

[Johannes Wolter]

Hi,

I hope I found the right mailinglist for my question. (I didn't find a 
specific game-engine list)
My problem is, that I want to take a screenshot (using the Python API), while 
the the game-engine's window is occluded by another window or even minimized.

Right now it seems to me that the Python-call "Rasterizer.takeScreenShot()"
dumps the framebuffer with "glReadPixels". Is it somehow possible to access  
the to be displayed "image" before it is "merged" with data from other X11 
windows in the framebuffer. (Do I need the software renderer (MESA?) for this 
task?)
As you probably see I'm not an expert in OpenGL; so thanks for any hint you 
can give me on how to solve this problem (or if it is at all possible).

Cheers,
Johannes
