You have to create a place to copy your pixmap to. If you are using 
32big Quickdraw then make use of the Graphic World calls to build 
yourself an off-screen pixmap. Otherwise, you can do it by hand or use 
the other routines Apple has provided in DTS sample code (15 and 16). 
Copy your image to the offscreen buffer then between the Open/Close 
Picture calls _Copybits that back to the screen ( you can also, just 
_copybits the screen image - current grafport - to itself ie: make the 
source and destination pixmaps the same thing).
