@Adam
Thanks for doing a quick review. I did a very basic although not full test for
the signature which worked fine. As generatePageMap() didn't work at all I also
don't think that it was used.
@Ngi
For a single bookmark entry you can do either
((PDPageDestination)item.getDestination()).findPageNumber()
if the bookmark entry is a PDPageDestination or
COSArray destination = (COSArray) item.getDestination().getCOSObject();
// Get the page reference from the destination
String pageKey = ((COSObject)destination.get(0)).getObjectNumber().intValue() +
"," + ((COSObject)destination.get(0)).getGenerationNumber().intValue();
// get the page number from the page map
int pageNumber = (Integer) document.getPageMap().get(pageKey);
for other Destination types.
You might want to look up the different types in the PDF reference (PDF:1.7,
section: 8.2.1)
