Is there a way to determine if a PDFPage contains only a picture? There seems to be plenty of routines for rendering/drawing in Core Graphics, but none for extracting PDF information?

You need to parse and analyse the page streams. Look up the documentation on CGPDFScanner (which is used for extracting PDF information), and of course the PDF reference.
