Re: getting and setting names of named destinations
Ok, sort of pigybacking off the previous discussions... I was able to get
PDFBox to allow me to get the page numbers of named dests, and even to alter
the zoom factor for each one. However, I cannot get and/or set the names
themselves (the actual names of the named destinations). Anyone got any
ideas? Would this be something that could be added into a future release?
Thanks,
Kevin

Re: getting and setting names of named destinations
Posted by Ad...@swmc.com.
Did you look at the PDF in a text editor? Check the object IDs and cross
reference them with the /Pages from the catalog in both the input file as
well as the output file. Once you see how these are lining up, you should
be able to figure out what the code is doing. Also, I'd start by just
removing one page from a small document (perhaps three pages total) to
keep things simple and easy to work with.

Re: getting and setting names of named destinations
Adam ,
I agree with you that this is the logical thing.
But still ... After I copied the PDF with all its bookmarks, then I
removed some pages, the bookmarks refer to the right location in the page,
but to wrong pages.
Here is my code, you can try it on the PDF you have downloaded :
String inputpath = "C:\\inputPDF.pdf"; // Has bookmarks with named
destinations.
String ouputpath = "C:\\outputPDF.pdf";
PDDocument inputPDFFile = PDDocument.load( inputpath );
PDDocument outputPDFFile = new PDDocument();
List<PDPage> inputPDFPages =
inputPDFFile.getDocumentCatalog().getAllPages(); // Get all pages of this
PDF.
// Copy/Paste all PDF pages :
for( PDPage page: inputPDFPages )
outputPDFFile.importPage( page );
// Copy/Paste all Named destinations :
PDDocumentCatalog destCatalog = outputPDFFile.getDocumentCatalog();
PDDocumentCatalog srcCatalog = inputPDFFile.getDocumentCatalog();
COSName names = COSName.getPDFName( "Names" );
PDDocumentNameDictionary destNames = destCatalog.getNames();
PDDocumentNameDictionary srcNames = srcCatalog.getNames();
if( srcNames != null ) {
if( destNames == null )
destCatalog.getCOSDictionary().setItem(names,
cloneForNewDocument(outputPDFFile, srcNames));
else
destNames.getCOSDictionary().mergeInto((COSDictionary)cloneForNewDocument(outputPDFFile,
srcNames));
}
// Copy/Paste all bookmarks :
PDDocumentOutline destOutline = destCatalog.getDocumentOutline();
PDDocumentOutline srcOutline = srcCatalog.getDocumentOutline();
if (srcOutline != null) {
if (destOutline == null) {
PDDocumentOutline cloned = new
PDDocumentOutline((COSDictionary)cloneForNewDocument(outputPDFFile,
srcOutline));
destCatalog.setDocumentOutline(cloned);
} else {
PDOutlineItem first = srcOutline.getFirstChild();
PDOutlineItem clonedFirst = new
PDOutlineItem((COSDictionary)cloneForNewDocument( outputPDFFile, first));
destOutline.appendChild(clonedFirst);
}
}
// Remove some pages :
outputPDFFile.removePage( 25 );
outputPDFFile.removePage( 24 );
outputPDFFile.removePage( 23 );
outputPDFFile.removePage( 22 );
outputPDFFile.removePage( 21 );
outputPDFFile.removePage( 20 );
outputPDFFile.save( ouputpath );
outputPDFFile.close();
Best regards ,
Hesham

Re: getting and setting names of named destinations
Posted by "Hesham G." <he...@gmail.com>.
Adam ,
I agree with you that this is the logical thing.
But still ... After I copied the PDF with all its bookmarks, then I removed some pages, the bookmarks refer to the right location in the page, but to wrong pages.
Here is my code, you can try it on the PDF you have downloaded :
String inputpath = "C:\\inputPDF.pdf"; // Has bookmarks with named destinations.
String ouputpath = "C:\\outputPDF.pdf";
PDDocument inputPDFFile = PDDocument.load( inputpath );
PDDocument outputPDFFile = new PDDocument();
List<PDPage> inputPDFPages = inputPDFFile.getDocumentCatalog().getAllPages(); // Get all pages of this PDF.
// Copy/Paste all PDF pages :
for( PDPage page: inputPDFPages )
outputPDFFile.importPage( page );
// Copy/Paste all Named destinations :
PDDocumentCatalog destCatalog = outputPDFFile.getDocumentCatalog();
PDDocumentCatalog srcCatalog = inputPDFFile.getDocumentCatalog();
COSName names = COSName.getPDFName( "Names" );
PDDocumentNameDictionary destNames = destCatalog.getNames();
PDDocumentNameDictionary srcNames = srcCatalog.getNames();
if( srcNames != null ) {
if( destNames == null )
destCatalog.getCOSDictionary().setItem(names, cloneForNewDocument(outputPDFFile, srcNames));
else
destNames.getCOSDictionary().mergeInto((COSDictionary)cloneForNewDocument(outputPDFFile, srcNames));
}
// Copy/Paste all bookmarks :
PDDocumentOutline destOutline = destCatalog.getDocumentOutline();
PDDocumentOutline srcOutline = srcCatalog.getDocumentOutline();
if (srcOutline != null) {
if (destOutline == null) {
PDDocumentOutline cloned = new PDDocumentOutline((COSDictionary)cloneForNewDocument(outputPDFFile, srcOutline));
destCatalog.setDocumentOutline(cloned);
} else {
PDOutlineItem first = srcOutline.getFirstChild();
PDOutlineItem clonedFirst = new PDOutlineItem((COSDictionary)cloneForNewDocument( outputPDFFile, first));
destOutline.appendChild(clonedFirst);
}
}
// Remove some pages :
outputPDFFile.removePage( 25 );
outputPDFFile.removePage( 24 );
outputPDFFile.removePage( 23 );
outputPDFFile.removePage( 22 );
outputPDFFile.removePage( 21 );
outputPDFFile.removePage( 20 );
outputPDFFile.save( ouputpath );
outputPDFFile.close();
Best regards ,
Hesham

Re: getting and setting names of named destinations
Posted by Ad...@swmc.com.
"So if I want to remove a page from the PDF, all Named destinations must
be updated manually to refer to the new pages numbers..."
Not true. The references are to not page numbers, but the actual object
IDs. When you delete a page, it just drops out of the list of pages (and
may or may not delete the actual page object, depending on what software
you are using). So the other pages don't change object ID nor revision
number.

Re: getting and setting names of named destinations
Adam ,
Thanks a lot for the investigation, and for putting me on the right way. I
have copied the code that copies the Named destinations from the
'PDFMergerUtility' code, and it worked fine. Here is my final code if any
body needs it :
I have only 1 problem ... As I understand the Named destinations written
at the PDF trailer contains the ND, and the page it refers to, right ?
So if I want to remove a page from the PDF, all Named destinations must be
updated manually to refer to the new pages numbers ... But how can I
update a bookmark page number, while keeping the Named destination as it
is ?
String inputpath = "C:\\inputPDF.pdf"; // Has bookmarks with named
destinations.
String ouputpath = "C:\\outputPDF.pdf";
PDDocument inputPDFFile = PDDocument.load( inputpath );
PDDocument outputPDFFile = new PDDocument();
List<PDPage> inputPDFPages =
inputPDFFile.getDocumentCatalog().getAllPages(); // Get all pages of this
PDF.
// Copy/Paste all PDF pages :
for( PDPage page: inputPDFPages )
outputPDFFile.importPage( page );
// Copy/Paste all bookmarks(The old code) :
//PDDocumentOutline pdfBookmarks =
inputPDFFile.getDocumentCatalog().getDocumentOutline(); // The bookmarks
root object.
//outputPDFFile.getDocumentCatalog().setDocumentOutline( pdfBookmarks );
// Copy/Paste all Named destinations :
PDDocumentCatalog destCatalog = outputPDFFile.getDocumentCatalog();
PDDocumentCatalog srcCatalog = inputPDFFile.getDocumentCatalog();
COSName names = COSName.getPDFName( "Names" );
PDDocumentNameDictionary destNames = destCatalog.getNames();
PDDocumentNameDictionary srcNames = srcCatalog.getNames();
if( srcNames != null ) {
if( destNames == null )
destCatalog.getCOSDictionary().setItem(names,
cloneForNewDocument(outputPDFFile, srcNames));
else
destNames.getCOSDictionary().mergeInto((COSDictionary)
cloneForNewDocument(outputPDFFile, srcNames));
}
// Copy/Paste all bookmarks :
PDDocumentOutline destOutline = destCatalog.getDocumentOutline();
PDDocumentOutline srcOutline = srcCatalog.getDocumentOutline();
if (srcOutline != null) {
if (destOutline == null) {
PDDocumentOutline cloned = new PDDocumentOutline((COSDictionary)
cloneForNewDocument(outputPDFFile, srcOutline));
destCatalog.setDocumentOutline(cloned);
} else {
PDOutlineItem first = srcOutline.getFirstChild();
PDOutlineItem clonedFirst = new PDOutlineItem((COSDictionary)
cloneForNewDocument( outputPDFFile, first));
destOutline.appendChild(clonedFirst);
}
}
//outputPDFFile.removePage( 21 ); // If we used this line it will cause
problems to the Named destinations.
outputPDFFile.save( ouputpath );
outputPDFFile.close();
Best regards ,

Re: getting and setting names of named destinations
Posted by "Hesham G." <he...@gmail.com>.
Adam ,
Thanks a lot for the investigation, and for putting me on the right way. I have copied the code that copies the Named destinations from the 'PDFMergerUtility' code, and it worked fine. Here is my final code if any body needs it :
I have only 1 problem ... As I understand the Named destinations written at the PDF trailer contains the ND, and the page it refers to, right ?
So if I want to remove a page from the PDF, all Named destinations must be updated manually to refer to the new pages numbers ... But how can I update a bookmark page number, while keeping the Named destination as it is ?
String inputpath = "C:\\inputPDF.pdf"; // Has bookmarks with named destinations.
String ouputpath = "C:\\outputPDF.pdf";
PDDocument inputPDFFile = PDDocument.load( inputpath );
PDDocument outputPDFFile = new PDDocument();
List<PDPage> inputPDFPages = inputPDFFile.getDocumentCatalog().getAllPages(); // Get all pages of this PDF.
// Copy/Paste all PDF pages :
for( PDPage page: inputPDFPages )
outputPDFFile.importPage( page );
// Copy/Paste all bookmarks(The old code) :
//PDDocumentOutline pdfBookmarks = inputPDFFile.getDocumentCatalog().getDocumentOutline(); // The bookmarks root object.
//outputPDFFile.getDocumentCatalog().setDocumentOutline( pdfBookmarks );
// Copy/Paste all Named destinations :
PDDocumentCatalog destCatalog = outputPDFFile.getDocumentCatalog();
PDDocumentCatalog srcCatalog = inputPDFFile.getDocumentCatalog();
COSName names = COSName.getPDFName( "Names" );
PDDocumentNameDictionary destNames = destCatalog.getNames();
PDDocumentNameDictionary srcNames = srcCatalog.getNames();
if( srcNames != null ) {
if( destNames == null )
destCatalog.getCOSDictionary().setItem(names, cloneForNewDocument(outputPDFFile, srcNames));
else
destNames.getCOSDictionary().mergeInto((COSDictionary) cloneForNewDocument(outputPDFFile, srcNames));
}
// Copy/Paste all bookmarks :
PDDocumentOutline destOutline = destCatalog.getDocumentOutline();
PDDocumentOutline srcOutline = srcCatalog.getDocumentOutline();
if (srcOutline != null) {
if (destOutline == null) {
PDDocumentOutline cloned = new PDDocumentOutline((COSDictionary) cloneForNewDocument(outputPDFFile, srcOutline));
destCatalog.setDocumentOutline(cloned);
} else {
PDOutlineItem first = srcOutline.getFirstChild();
PDOutlineItem clonedFirst = new PDOutlineItem((COSDictionary) cloneForNewDocument( outputPDFFile, first));
destOutline.appendChild(clonedFirst);
}
}
//outputPDFFile.removePage( 21 ); // If we used this line it will cause problems to the Named destinations.
outputPDFFile.save( ouputpath );
outputPDFFile.close();
Best regards ,
Hesham

Hesham,
Okay, I was now able to duplicate your findings. Let's start with the
input file and see how that's laid out. We'll start with the trailer and
proceed from there:
trailer

% Note that 19148 0 appears multiple times, so we're dealing with a
non-conforming PDF

% we should go through all of these, but since I already found our target
bookmark ("Classes"), I'll skip straight to 7715 0

% again, normally we'd have to go through each of these, but since I know
where it's at, we'll skip right to 10041 0 (I cheated and found the
bookmark and then worked backward to get to the document root)

endobj
Okay, so that PDF was non-conforming, but it was good enough that I'd
expect PDFBox to be able to parse it. Let's take a look at the output and
see what went wrong.
% we'll start at the trailer
trailer
<<
/Root 1 0 R
/ID [<78E9221F1CF4B2B411AC7654A2B830A0>
<78E9221F1CF4B2B411AC7654A2B830A0>]
/Size 14095
>>
% then progress to the root
1 0 obj
<<
/Type /Catalog
/Version /1.4
/Pages 2 0 R
/Outlines 3 0 R
>>
endobj
Ah ha, we don't have /Names, which means we can't have any named
destinations. Now, think about why this might be. What did we copy over
when we made this new PDF? Just the pages. We didn't copy over the
outline, nor any of the named destinations. So I wouldn't say there's any
bug in PDFBox here (at least not based on what I've seen thus far). The
reason it worked in the previous file was because it wasn't a named
destination which was used, it was a page reference and a specific x,y
value.
The reason I went through this long example is to show you how I figured
out where the problem lies. I hope that part was helpful. I don't really
have an answer on how to fix this, but I can at least show you why it's
breaking. I'm pretty sure you know more about named destinations than I
do, so hopefully you can take this information and put it to good use. I
did just notice that PDFMergerUtility::appendDocument() handles the
catalog Names. You might be able to look there for an example.
PDDocumentNameDictionary destNames = destCatalog.getNames(); I can't say
whether or not this will have all the information you're looking for or
not, but it should at least be a good first step.
Let me know if you have any other questions.

Re: getting and setting names of named destinations
Adam ,
Thanks a lot for your time and effort.
The PDF sample you have downloaded is a small sample that I used a
splitter program to split part of my big PDF so you can download it
easily. I have tested this small PDF now and you are right it worked fine
... I think the splitter did that fix.
But when I tried the same code on the original big PDF it did not work. I
tried PDFBox latest version 1.2.1 to test it. When I click on any of the
bookmarks, nothing happens.
If you have time please test the same code on the original PDF, here :

Re: getting and setting names of named destinations
Posted by "Hesham G." <he...@gmail.com>.
Adam ,
Thanks a lot for your time and effort.
The PDF sample you have downloaded is a small sample that I used a splitter program to split part of my big PDF so you can download it easily. I have tested this small PDF now and you are right it worked fine ... I think the splitter did that fix.
But when I tried the same code on the original big PDF it did not work. I tried PDFBox latest version 1.2.1 to test it. When I click on any of the bookmarks, nothing happens.
If you have time please test the same code on the original PDF, here :

Re: getting and setting names of named destinations
Posted by Ad...@swmc.com.
Hesham,
The first thing I did was download the PDF and look at it. That didn't
help much since everything is compressed, so I decompressed it using pdftk
so it's human readable. Then I found the object which links to a specific
place in a page, I chose the "Classes" bookmark.
53 0 obj
<<
/First 54 0 R
/Title (Classes)
/Parent 49 0 R
/Dest [29 0 R /XYZ 109 639 null]
/Count 1
/Next 51 0 R
/Last 54 0 R
/Prev 52 0 R
>>
The destination is "29 0 R" which is a page, and the XYZ is also set. I
had to look that one up in the spec and found it in section 12.3.2.2. This
is the left, top, and zoom. So the point 109,639 will be in the top left
corner when clicking the link. At this point I at least know how it
works. As a final test, I searched the PDF for "G917701" and did not find
anything.
Then I ran you sample code on the uncompressed file. Before even opening
it with Adobe, I traced from the trailer -> root -> catalog -> through the
bookmarks until I got to object 77, which was the "Classes" bookmark. It
looked correct, so I opened the file in Adobe Reader and it worked just
fine. This confirms that there is not a problem in importPage() under all
circumstances (if at all).
I then ran that same code with the original, compressed PDF and the
"Classes" bookmark worked fine. So I'm unable to duplicate your test
results. For reference, here's the object from the output file when using
the exact file I downloaded from your link:
76 0 obj
<<
/Next 62 0 R
/Parent 44 0 R
/Dest [86 0 R /XYZ 109 639 null]
/Title (Classes)
/Prev 77 0 R
/Count 1
/Last 89 0 R
/First 89 0 R
>>
I do not have enough time to look into this any further and try to
determine how to set named destinations, however I'll do my best to try to
get you squared away with simple tests like this one. If you're not
getting the same results as me with this simple test, it may be that
fixing this problem will also resolve other issues you're facing.
I'm using the latest code from SVN, which may be a difference between my
system and yours. So take a look at the objects in your output PDF (using
a decent text editor) and see if anything is different. Trace around and
see if the destination page is actually a page object, and if it is listed
in the /Pages section. If everything looks like it's correct in the file,
but the bookmark still doesn't work, post your output file somewhere
online and link us to it like you did with the example file below.
As long as I can run a quick test in just a few minutes (like your example
here) and know exactly what to look for, I should be able to take a look.
It's just when the code gets long and complex that it'll be an issue. As
long as your reports are as short and concise as this one, I'm sure we'll
get it resolved quickly.

Adam

Re: getting and setting names of named destinations
Kevin and Adam ,
I have made some tests and i am now sure of the problem ... The problem is
not in the method setNamedDestination( "G917701" );
The main problem is if i use importPage(...) to copy/paste some pdf pages,
then copy their bookmarks. Here is a code sample where i copy a PDF having
Named destinations bookmarks to another new PDF :
public void copyPDFWithNDBookmarks() {
String inputpath = "C:\\inputPDF.pdf"; // Has bookmarks with named
destinations.
String ouputpath = "C:\\outputPDF.pdf";
try {
PDDocument inputPDFFile = PDDocument.load( inputpath );
PDDocument outputPDFFile = new PDDocument();
List<PDPage> inputPDFPages =
inputPDFFile.getDocumentCatalog().getAllPages(); // Get all pages of this
PDF.
// Copy/Paste all PDF pages :
for( PDPage page: inputPDFPages )
outputPDFFile.importPage( page );
// Copy/Paste all bookmarks
PDDocumentOutline pdfBookmarks =
inputPDFFile.getDocumentCatalog().getDocumentOutline();
outputPDFFile.getDocumentCatalog().setDocumentOutline( pdfBookmarks );
outputPDFFile.save( ouputpath );
outputPDFFile.close();
} catch (IOException e) {
e.printStackTrace();
} catch (COSVisitorException e) {
e.printStackTrace();
}
}
You can try this PDF as an input PDF:
http://www.4shared.com/document/XrPhJSCd/sample_pdf_having_bookmarks_wi.html
When you open the output PDF and click any bookmark ... Nothing will
happen
!
I think this is a problem in PDFBox importPage(...) method.
Adam ... Can you please check this out ?
I have checked the mailing list, and i see many people asking about the
Named destinations, but they mostly reach a dead end.

Hesham,
I'm sorry to mislead you. I looked at my notes and it turns out I never
created them; I just edited them. So I a'm not sure I can help you. I am
very interested in this and will experiment with it next week.
Has anyone out there been able to create named destinations using pdfbox?

Strange ... I will try to dig in this, and I will be waiting your reply for more details if you can help.
Happy trip ...

No, I was able to get mine to work sorta... the named destinations are
problematic tho. I am sorry, but I am going out of town for a week. But I
will post on this when I get back. Good luck.

Kevin ,
You said you were having problems setting a named destination. I have tried to define a bookmark named destination but it didn't work.
Here is my code :
PDNamedDestination pn = new PDNamedDestination();
pn.setNamedDestination( "G917701" );
bookmark.setDestination( pn );
When I open the PDF & click on that bookmark, nothing happens. I have a PDF editor that shows me the bookmark destinations ... So when I showed the named destination for this bookmark, it was empty !
Some how it was not set at all. Is this the problem you are facing ?
Best regards ,
Hesham
Re: getting and setting names of named destinations
Posted by Kevin Brown <kb...@gmail.com>.
Thanks a lot. I was able to get them as well. However, I still run into some
problems when I set them. I've decided to use a different means to set them
for my work, so I don't need PDFBox for that any more. However it would be
nice if it worked a little better (IMHO).

Kevin ,
I have been investigating the Named destinations for bookmarks, and i
remembered your problem. Please try this example to get the names of the
destinations ... I hope it's right :
try {
PDNamedDestination pn = (PDNamedDestination)bookmark.getDestination(); //
The bookmark = A PDOutlineItem object.
if( pn != null ) System.out.println("Page: " + (pageNumber + 1) + " - Named
dest: " + pn.getNamedDestination());
} catch (Exception e) {
e.printStackTrace();
}
When i executed this on one of my PDFs here is the result :
Page: 2 - Named dest: G917701
Page: 3 - Named dest: G976457
Page: 5 - Named dest: G983176
.....
Best regards ,
Hesham
Re: getting and setting names of named destinations
Posted by Kevin Brown <kb...@gmail.com>.
I've figured this out. Basically you get a Map from getNames() and can fix
the destination names (keys), then use setNames(). However this seems to
break the destinations in a way that I do not understand. I will keep
plugging away and will post code samples when I have it worked out.
Anyone else interested in this, please chime in with your thoughts and
experience.
