Hi,
First, sorry if this is not the correct way to post, I was unable to locate the
PDFBox forum
other than thru MarkMail.
Second, I know there are two post regarding this topic, I've read both of them.
Getting page number for bookmarks (BM-Thread)
How to get Page Number from a PDPage (PDP-Thread)
I'm using Adobe Acrobat 8 Pro.
I am using PDFBox on a Hibernate Search In Action PDF, but i think this problem
would be the same on other Book PDFs
When I open a pdf doc in acrobat there are two indication of which page I am
on,
[ pageN ] ( page# of total#), in acrobat these two number DON't always match.
In fact the [pageN] matches the one you would see on the printed page, while
(page# of total#) is an indication of the total number of Sheets of pager in
the book,
ie including all the pages before page 1, TOC, copyright ...
It seems that when I use the code in the BM-Thread, references to the first 21
Sheets
all indicate Page 1 and thereafter this format provides the [pageN] value i.e.
the number
that you would see on the printed page of a book.
With BM-Thread I see the following problems:
1. Bookmarks have PDAction = null
2. The book is divided into Parts/Chapters/SubChapters/... There are bookmarks
for each. However only Parts has PDAction, and each Part shows the same
Page (1) as in page = 1.
3. The Index bookmarks don't show the [page#], they show the sheet#
When I use the code from the PDP-Thread, I get the number which is basically
the
sheet count, i.e page# from the above (page# of total#) except that it doesn't
work
once you get to the Book Index.
It seems like it would have been easier if I could get PDPageDestination from
PDOutlineItem and then use pdpageDest.getPageNumber(), but the type coming
back from PDOutlineItem.getDestination is PDNamedDestination.
Basically, I just modified the PrintBookmarks.java to get the results:
while (current != null) {
dest = current.getDestination();
pdAction = current.getAction();
if (pdAction != null) {
// From BM-Thread
COSObject targetPageRef = (COSObject) ((COSArray) current
.getAction().getCOSDictionary()
.getDictionaryObject("D")).get(0);
String objStr = String.valueOf(targetPageRef.getObjectNumber()
.intValue());
String genStr = String.valueOf(targetPageRef
.getGenerationNumber().intValue());
szKey = objStr + "," + genStr;
pageNumber = (Integer) getPageMap().get(objStr + "," + genStr);
} else if (dest != null) {
// From PDP-Thread
PDPage pdp = current.findDestinationPage(document);
document.getDocumentCatalog().getPages();
List allpages = new ArrayList();
document.getDocumentCatalog().getPages().getAllKids(allpages);
pageNum = allpages.indexOf(pdp) + 1;
if (dest instanceof PDNamedDestination) {
szDest = ((PDNamedDestination)dest).getNamedDestination();
}
}
System.out.println(indentation + current.getTitle() + " ... page: "
+ pageNumber + " key: " + szKey + " dest: " + szDest
+ " pageNum: " + pageNum);
printBookmark(current, indentation + " ");
current = current.getNextSibling();
}
