Hi all.   

Am I right in thinking that the CoreGraphics api isn't supported/wrapped by pyobjc ? 
Is it by lack of time/interest, or because of some difficulties ?   

I need to do simple collision detection of 2D bitmaps.  By using NSImage and composing function, I'm able to create an NSCachedImageRep, empty only when there is no collision. 
My question is : how to bring this back to the memory, so I can read it with python ? 
It seems to be possible thru CGContext, but is there another way ?  

My other solution would be to wrap the whole collision detection system, using CGContext, in a pyrex generated module. Is there any problem I should be aware of before trying ?   

Thanks a lot for any light you could cast on this ...
