If I understand... you're going all the way to NSGraphicsContext just to flip the coordinate system? That's a long row to hoe :-). Try something like (typed into mail) CGContextTranslateCTM(pdf_context, 0, 100); # where 100 is the height of the context... CGContextScaleCTM(pdf_context, 1.0, -1.0); use that instead of trying to set the flipped bit.
