My ultimate goal is an application that is like a printer's PDF workflow, that will allow page manipulations like resizing / cropping / adding bleed information, and imposing multiple pages onto one with crop marks and the like. After researching it seems like some of the functions (imposition with crop marks, page cropping/ scaling with/without preserving aspects, etc) are best suited for quartz, while the rest (page reordering/inserting, rotating, etc) have Cocoa APIs. I'm not clear on how to accomplish the more advanced requirements without creating a CGPDFDocumentRef to draw into a custom quartz context.

If there is a more sane way to accomplish these tasks please let me know! :)

Thank you for your help!

Joel was right. I think it would be easier for you to stay in PDF Kit (PDFView) and do your transforms there.

Since I don't know exactly what you are doing, I can't recommend specific advice. If you explain what you think you need to do with CGPDFDocumentRef, I'll try to suggest a parallel way of doing it in PDF Kit.
