screen capture?

[Keith W. <kw...@cs...>]

How do I grab a screen capture of a rendered window?  If I do the  
fairly straight forward process of copybiting the window's contents  
into a gworld, the gworld comes up blank (white) even though the  
window is showing a rendered image.  I can manually do a screen  
capture with various utilities (such as Applications/Grab or cmd- 
shift-3...I think), but I can't do it from within the program?  I'm  
doing the copybiting outside the rendering phase (after  
Q3View_EndRendering and Q3View_Sync...or before  
Q3View_StartRendering, however you prefer to look at it).

Does this make any sense?

Likewise, when using Applications/Grab, I often get a partially  
rendered image captured.  If I pause my program by halting the  
rendering loop entirely, then I can use Grab just fine and it never  
has this problem.

Thanks.
