Basically, a bookmark will just have a title and a reference to a page object. Once you get the reference to the page, it's just a matter of looking up the object id and determining which page that is (which is where the page map comes in handy). Give your bookmark a unique name, save it, then open the PDF in a text editor (vi, emacs, Notepad++, etc.). Search for the bookmark title and you should be able to see how the file is laid out. Its actually quite easy to read. Just have the PDF spec handy to look up what each of the numbers mean (you don't have to read the whole thing, just jump to the section on bookmarks).
Another nice tactic is to open the debugger and just go through memory until you find the object ID you're looking for. Once you find it, figure out how to access it. --Adam From: Tim Reynolds <[email protected]> To: [email protected] Date: 02/24/2010 14:19 Subject: Re: How to get Page Number from Bookmark conflicting results Adam, Thanks for your reply It looks to me that the content of PDF Bookmarks very widely between PDFs. I checked PDF books that I own from 3 different Publishers. The COSBase returned from PDDestination.getCOSObject() COSArray, COSString, COSName, at least those are the ones I found. I did download the PDF Spec : http://www.adobe.com/devnet/acrobat/pdfs/PDF32000_2008.pdf. I must admit its quite lengthy and I have not read exactly how to get to the info I need yet. My goal is to lucene-index the BookMarks, search them and then be able to jump to the page indicated by the bookmark, I'm not sure yet if this will be possible. I did see this in the examples: GoToSecondBookMarkOnOpen.java PDOutlineItem item = bookmarks.getFirstChild().getNextSibling(); PDDestination dest = item.getDestination(); PDActionGoTo action = new PDActionGoTo(); action.setDestination(dest); document.getDocumentCatalog().setOpenAction(action); document.save( args[1] ); maybe this will provide me with some more clues. I did attempt several tests on the code snippet you provided but I could not get the page number when PDAction == null, ie dest != null. As I stated above the COSObject in many cases is not COSArray again thanks for you input I will take a closer look at getPageMap(). Tim ?
