toArray returns an array of PDPage objects. Since the PDPage objects do
not contain the page ID (as far as can tell), this will not suffice.
Likewise iterator() and listIterator() both iterate over collections of
PDPages. What I need is a list of object IDs for the pages; I don't want
the actual data in the pages.

Re: Get page number for bookmark
Hi Adam,
did you ever try to use one of the following methods:
COSArrayList.iterator
COSArrayList.listIterator
COSArrayList.toArray
All of them should return the data you're looking for.
