Adding Marks on a PDF

[ziden]

Hello there.

 

 Is it possible to make iText open a previously made PDF by ireport, and add marks on it ?

 Im not sure how would be done, heres what ive got:

 

Paragraph cTitle = new Paragraph("This is chapter " + i, chapterFont);

writer.setViewerPreferences(PdfWriter.PageModeUseOutlines);

Chapter chapter = new Chapter(cTitle, 0);

section.add(Chunk.NEXTPAGE);

document.add(chapter);

 

is this correct ? how could i open a PDF with some anchors and link them to marks so people who open the pdf can navigate easyly ?

 

Thanx for any attention.

 Just posting some improvements.

 

Im using the following code to generate an empty pdf for example with that bookmark menu

        Document document = new Document();

        PdfWriter writer = PdfWriter.getInstance(document,

        new FileOutputStream("C:/Menu.pdf"));

        document.open();

        document.add(new Chunk("Chapter 1")

        .setLocalDestination("chappy1"));

        PdfContentByte cb = writer.getDirectContent();

        PdfOutline root = cb.getRootOutline();

        PdfOutline oline1 = new PdfOutline(root,

        PdfAction.gotoLocalPage("chappy1", false),"Go to Chapter 1");

    So, this is kinda simple: i can create an anchor and link the bookmark to the anchor on a new PDF. What i need is, to do this onto an existing PDF with previously anchors created. Ireport allows me to create anchors with the <anchorNameExpression> tag, all i would need to do is open that pdf and add the bookmark menu to it

but it seems i cannot do that, at least not as im tryng to do. I belive this would be usefull to many of you as well as it would be to me.

    Does anyone have any idea on how to do that ? My last tryout was doing a Menu.pdf and a Main.pdf, one with anchors other with bookmarks, then i tryed to concat em both using this code:

  public static void concatenarPdfs(List<InputStream> pdfs, FileOutputStream out) throws Throwable {

        PdfCopyFields copy = new PdfCopyFields(out);

        for(int x  = 0; x < pdfs.size() ; x++) {

            //byte [] temp = pdfs.get(x)

            byte[] bytes = new byte[pdfs.get(x).available()]; // cria vetor de bytes do tamanho dos bytes do pdf

            pdfs.get(x).read(bytes); // passa os bytes pro vetor

            PdfReader reader = new PdfReader(bytes); // cria um pdfreader com os bytes do pdf lido

            copy.addDocument(reader); // junta os 2

        }

        copy.close();

    }

 

  It concatenates both pdfs nicely, but it doesnt keep the bookmarks :(

 

  Does anyone have any ideas on how this could be possible ?

 

  Thanx for any attention, i would apreciate it.

 Just posting to show progress.

 

 Ive managed to make the whole PDF with the bookmark menu, however i couldnt anchor it correctly. How could i ?

 

 Heres the code i have so far:

 

  PdfReader reader = new PdfReader(new FileInputStream("C:/Curso.pdf"));

         

        Document document = new Document();

        

        PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("C:/Menu.pdf"));

        

        document.open();

        

        PdfContentByte cb = writer.getDirectContent();

        // Load existing PDF

       

        int paginas = reader.getNumberOfPages();

        

        for(int pag = 1 ; pag <= paginas ; pag ++) {

            PdfImportedPage page = writer.getImportedPage(reader, pag);  

            document.newPage();

            cb.addTemplate(page, 0, 0);

        }

 PdfOutline root = cb.getRootOutline();

        

        // Code 3

        PdfOutline oline1 = new PdfOutline(root,

        PdfAction.gotoLocalPage("prof", false),"Profissional");

        

        PdfOutline oline2 = new PdfOutline(root,

        PdfAction.gotoLocalPage("reconhecimento", false),"Reconhecimento");

        oline2.setOpen(false);

        PdfOutline oline2_1 = new PdfOutline(oline2,

        PdfAction.gotoLocalPage("2.1", false),"Sub 2.1");

        PdfOutline oline2_2 = new PdfOutline(oline2,

        PdfAction.gotoLocalPage("2.2", false),"Sub 2.2");

        

        PdfOutline oline3 = new PdfOutline(root,

        PdfAction.gotoLocalPage("opcaolingua", false),"Opção Língua");

        

        document.close();

 

 

 At my iReport, i added some anchor tags such as 

 <anchorNameExpression>"prof"<\anchorNameExpression>

but when i click the following bookmark

 PdfOutline oline1 = new PdfOutline(root,

        PdfAction.gotoLocalPage("prof", false),"Profissional");

it doesnt redirects me into the selected anchor. Is there something i am doing wrong ?
