These two documents will get you on the road to using QCView successfully. What'll you end up doing is telling the QCView to load your composition, setting your new image programmatically via published input keys, and then telling the QCView to begin rendering.

Hi, I have a quartz composition and want to render it ontop of a NSImageView. The composition should use the NSImageView as BG, instead it always uses its erase color to fill transparent images.
Any idea how I can make the QTView truly transparent?
Thanks,
Dominik
