Hi,
you might need to know what each dictionary servers to, because each of
them references its dependencies differently, not talking about content
streams, which have the references (partly) inside the stream itself.
I mean, to have it done you should read the PDF standard and do the
object searching according to it, while some of the references can be
references to real objects, some can be stored "inline". That is to
construct a real "tree" (some objects like fonts can (and should) be
reused, not talking about XObject-s), you need to know the PDF data
structure very well.
Bye,
