RE: [iText-questions] problem with bookmark

From: Paulo Soares <psoares@co...> - 2003-12-22 15:27

See the class SimpleBookmark in the new iText version at =
itextpdf.sf.net. It has an export to xml capability. The bookmark list =
itself is documented and very easy to use in case you need to make other =
format.

ok thanks this looks like what I'm looking for:) but when I try it I =
have a bug during execution:

this is my code:

		PdfReader pdfReader =3D new PdfReader(myPdfDocuments[currIdx]);
		List list =3D SimpleBookmark.getBookmark(pdfReader);

and the execution stop at the red line below:
in bookmarkDepth's method

 else {
                PdfDictionary action =3D =
(PdfDictionary)PdfReader.getPdfObject(outline.get															=
(PdfName.A));
                if (action !=3D null) {
                    if =
(PdfName.GOTO.equals(PdfReader.getPdfObject(action.get																			=
	(PdfName.S)))) {
                        dest =3D =
PdfReader.getPdfObject(action.get(PdfName.D));
                        if (dest !=3D null) {
                            if (dest.type() =3D=3D PdfObject.STRING)
                                map.put("Named", dest.toString());
                            else if (dest.type() =3D=3D PdfObject.NAME)
                                map.put("Named", =
PdfName.decodeName(dest.toString()));
                            else if (dest.type() =3D=3D PdfObject.ARRAY) =
{
                                ArrayList arr =3D =
((PdfArray)dest).getArrayList();
                                StringBuffer s =3D new StringBuffer();
                                =
s.append(pages.get(((PdfIndirectReference)arr.get																				=

                                s.append(' =

                                for (int k =3D 2; k < arr.size(); ++k)
                                    s.append(' =

                                map.put("Page", s.toString());
                            }
                            map.put("Action", "GoTo");
                        }
                    }


the error is:

java.lang.ClassCastException: com.lowagie.text.pdf.PdfNumber

I found a problem in your source code in the method bookmarkDepth():

	you try to cast a PdfNumber into a PdfIndirectReference. or this is not =
possible.
     =
//s.append(pages.get(((PdfIndirectReference)arr.get(0)).getNumber()));
	=09
	So I replace your code by this one and it looks like to done what we =
want.

		PdfNumber interm1 =3D (PdfNumber)arr.get(0);
		s.append(interm1.intValue());

What do you mean about my solution? I'm wrong o not?

thanks a lot:)

bye bastien.

That code would be correct for a GOTOR but not for a GOTO action as in =
this case. I suspect the pdf is broken.

The /Dest you have would only be valid for the GoToR action and that's =
not the case here. You should have something like:
=20
/Dest [12 0 R /FitH 354.250]
=20
You have to explain a lot better what you want to do and how you are =
doing it.

	Hi,

	I'm working on the pdf bookmark.

	But I have a little problem. I have pdf whych have their bookmark =
defined like this:

	[PDF CODE]

	65 0 obj

	<<

	        /Title(=FE=FF a b s t r a c t)

	        /Parent         63 0 R

	        /Next           66 0 R

	        /Prev           64 0 R

	        /Dest           [0 /FitH 354.250]

	>>

	[/PDF CODE]

	Here, this bookmark links on the page 1 of my pdf.


	I have other pdf whych define the bookmark like this:

	[PDF CODE]

	65 0 obj

	<<

	        /Title(=FE=FF a b s t r a c t)

	        /Parent         63 0 R

	        /Next           66 0 R

	        /Prev           64 0 R

	        /Dest           [1 /FitH 354.250]

	>>

	[/PDF CODE]

	Here, this bookmark links to the page 1 of my pdf.

	Acrobat reads both very well and the bookmarks are good too.

	So I think, there is a value in my pdf whych say that the first page =
index is 0 or 1. I'm wrong?

	But I don't find this value, can you help me please?

	When I use Itext to copy a pdf to a new pdf if the first page of my pdf =
is coding by 0 (eg1), my bookmarks are false, and I have a shift of 1 =
page on all my bookmarks.

	Thanks in advance,

	Bastien PIGEYRE

Ok Paulo I understand what you say.

But in my case I have pdf wih GoTo only. So perhaps my question is not a =
Itext question but a pdf question.
When I have a pdf with GoTo action, how I know the index of the first =
page of my document (0 or 1)?

In resume, I would like to manage the bookmark for the GoTo action too.

Thanks,

You must traverse the page tree to get the page references. The order in =
the page tree determines the page number. In the GoTo action you have =
the page reference that corresponds to some page number found before.
