Hi,
I created a CoreImage composition using some CIFIlters. The result of
the composition is a semi-transparent image. This is all working
without any problems when I draw the image into an empty NSView. Now
I concat a NSAffineTransform and rotate the graphic context. Also
working well..
But If I start drawing anything in white color behind this NSView
(even another NSView, e.g. NSColorWell), the result will be bad on
PowerPC Macintosh (tested G4 and G5) but good on Intel Macs (iMac +
Mac Mini tested).
I created a test project on http://www.thomasdingler.de/dev/
CoreImageTest.zip (61Kb)
The result on Intel Mac is like: http://www.thomasdingler.de/dev/

The result on PPC Mac is like: http://www.thomasdingler.de/dev/

Any Ideas???
Best regards,
Thomas Dingler
