Most PDFs do contain lots of binary looking parts in between some ASCII.

Is there a trick, tool, or command that will convert binary PDF parts to ASCII/ANSI? (Preferably "free as in be...

CGPDFDictionaryRef to something useful
A little bit of background: I'm appending an image to an already existing pdf file. I found out that there isn't a way to just add a page to it, you must recreate the whole pdf, then remove the old one then move the new one.
