Hi all,
I face to a problem while adding bookmark to existing pdf file. I use
itextsharp.dll, the version is 5.0.2.0.
When I want to get root outline, content root outline is null and it gives me a
NullReferenceException.
So I cannot add subOutline objects to pdf.
Is it possible to create a new root outline object ? How can I create
PdfOutline object and add it to existinng pdf file?
I'm new with iText, so I need your help..
The code is as follows:
PdfReader reader = new PdfReader(sourceFile);
Document document = new Document(reader.GetPageSizeWithRotation(1));
PdfWriter writer = PdfWriter.GetInstance(document, new
FileStream(destinationFile, FileMode.Create));
document.Open();
PdfContentByte contentByte = writer.DirectContent;
PdfOutline pdfOutlineRoot = contentByte.RootOutline;
// Define the destination
PdfDestination pdfDest = new PdfDestination(PdfDestination.FITH);
// Define the actions
PdfAction pdfAction1 = PdfAction.GotoLocalPage(1, pdfDest, writer);
PdfAction pdfAction2 = PdfAction.GotoLocalPage(2, pdfDest, writer);
// Define the outlines
PdfOutline pdfOutline1 = new PdfOutline(pdfOutlineRoot, pdfAction1, "Page
1");
PdfOutline pdfOutline2 = new PdfOutline(pdfOutline1, pdfAction2, "Page
2");
contentByte.AddOutline(pdfOutline1, pdfOutline1.Title);
contentByte.AddOutline(pdfOutline2, pdfOutline2.Title);
document.Close();
