Hallelujah!!! Thanks Stephen, that's the piece of the puzzle I was missing. I was assuming (or misinterpreting) that passing flipped:YES for the NSGraphicsContext ACTUALLY FLIPPED the context, not just informed it that the context had been flipped.
I found I had to set the CTM after the CGPDFContextBeginPage - looks like that might be resetting it, but basically, it works, I now get a right-way up PDF file. Now I know my source data really is right-side up, I can figure out the second part which is making sure images that embody it DRAW right-side up. thanks again, greatly relieved! --Graham On 28/05/2010, at 5:11 PM, Stephen J.
