I too have ran into this issue recently, with an old project that is half-resurrected. Performance was good in 10.5, but now horrible in 10.6. I'm not sure what to do instead. The CIImage docs say "Core Image images are immutable", and indeed I don't see any method like bitmapData. :( -- ____________________________________________________________ Sean McBride, B.
