You can also create a CGBitmapContext (with CGBitmapContextCreate) and
create a CIContext from that (with +[CIContext
contextWithCGContext:options:]) and draw to the CIContext. It will
draw the pixels into the bitmap. This will work for Tiger and Leopard.

If you are using Leopard (10.5), you could do something like this:
CIImage* imageBlurred = .....
NSBitmapImageRep* bitmap = [[[NSBitmapImageRep alloc]
initWithCIImage: imageBlurred] autorelease];
// Getting pixels data
// this returns a pointer to the pixel data
[bitmap bitmapData]
