I understand that contexts can (still) be flipped. Let's break this down a bit, since I'm fighting two problems simultaneously here. First, PDF File generation. Using the code I quoted, I generate PDF data in a flipped context. The flipped context matches the coordinate system that drawn objects expect. As such, objects and text are all positioned in the correct relative locations. If I write the PDF data immediately to a file, no NSImage or rep involved, result is an upside down PDF file when it's opened in Preview. If I generate the PDF data in a non-flipped context, the PDF File is still upside down, with the added problem that text glyphs are inverted individually. So at no point have I done anything with this image like draw it anywhere. How can it even be possible for PDF data in a file to be inverted? The problem appears to be with the PDF generation, so what's wrong there? > Do you have or can you obtain access to the 2007 WWDC videos? :-) > Not sure - will try to find them. So far a search on ADC brings up just one result and it's in Japanese... --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
