I need to get a CGImage out of a NSBitmapImageRep. This needs to work in
10.4.
I tried doing this by setting the bitmap as the graphics context and then
creating the image form the context. This gives me an CGBitmapContextCreate:
unsupported parameter combination. Here is the code

NSGraphicsContext * context = [NSGraphicsContext
graphicsContextWithBitmapImageRep:offscreenRep];

CGContextRef bitmapContext = (CGContextRef)[context graphicsPort];

CGImageRef image = CGBitmapContextCreateImage (bitmapContext);

I suspect there is a better way to do this. Does anyone have any
suggestions.

enjoy
