It helps to understand how PDFs are structured (objects, references, named
destinations, etc.), but the following should help you either way.
First, you'll need to get the object id and generation that the bookmark
points to, like this:
targetPageRef =
(COSObject)((COSArray)item.getAction().getCOSDictionary().getDictionaryObject("D")).get(0);
But sometimes it's not an indirect reference, but rather a named
destination. This is less common, but it does happen and is completely
valid according to the PDF spec. To make sure you can handle those cases,
you'll have to do something like this:
PDDestination dest = item.getDestination();
targetPageRef = (COSObject)((COSArray)dest.getCOSObject()).get(0);
Once you have the reference, it's just a matter of looking it up in the
page map...
String objStr =
String.valueOf(targetPageRef.getObjectNumber().intValue());
String genStr =
String.valueOf(targetPageRef.getGenerationNumber().intValue());
Integer pageNumber =
(Integer)doc.getPageMap().get(objStr+","+genStr);
Watch out for NULL values. They can appear virtually anywhere, and if you
don't check for them, you'll be sure to eventually get some PDF which will
cause a NullPointerException.
In the examples above "item" is of type PDOutlineItem
PDDocumentOutline root = doc.getDocumentCatalog().getDocumentOutline();
if(root != null) { // if there's no outline, there are certainly no
bookmarks!
PDOutlineItem item = root.getFirstChild();
}
And subsequent bookmarks can then be obtained via: item.getFirstChild()
and item.getNextSibling()

About bookmark
Hi,
I need to find the page number which they have the same content of the
bookmark.
I use the following code to get the content of the bookmark, but is their
any way to find the page number of each bookmark? Then i will compare the
bookmark content. Finally, i can get the page number containing the same
bookmark content.
CODE:
PDOutlineItem child = item.getFirstChild();child.getTitle()
