Hi all,
can anyone think of a way to get an NSData object out of a CGPDFPageRef?

Yes, because the ivar is synthesised, addressing myFoo would send the release

I would advise you to check the transparency in your image. Compositing is not
a simple task to do. And with the Core Animation Instrument, you can see your
FPS and you can color layers that are rendered offscreen. That might give you
some clues.

I just checked OSXvnc's source code. Their code led me to the right place, but

The functions needed for this are in Quartz / Core Graphics.
Thanks for your reply Kyle!
Well, I don't know the exact data structure of pdfs but I'm just figuring it

Sure, CGEventCreateKeyboardEvent was the first obvious way (and probably the
one I'll stick with).
