Hi Support,

I have a PDF which contains many pages, Now i want to insert Navigate to Table of Contents (TOC) link in Header and Footer of All pages.

Note : The PDF is already avai;able and may or may not be generated using "Aspose"

Is there any way in Aspose by which we can insert Header and Footer to an existing PDF?

Please find the attached sample PDF.

Thanks in advance.

Hi,

Learn about Aspose.Pdf, a component for generating PDF files from scratch. Note that you cannot use this component to modify existing PDF files.

We also have Aspose.Pdf, which allows you to manipulate/edit existing PDF files. You can add headers and footers to your existing PDF file using this component.

You can use PdfFileStamp to add headers and footers to a PDF file. However, PdfFileStamp currently does not support adding hyperlinks to headers and footers. As a workaround, use the PdfContentEditor class to add LocalLinks to the TOC page. The workflow is as follows:

  1. Add the header/footer to the existing PDF file using the PdfFileStamp class.
  2. Add hyperlinks to all pages of the PDF file, pointing to the TOC page, at the same point where the header/footer is placed.

Please try the following code snippet to accomplish this requirement. You can find the resultant PDF file generated based on your requirements in the attachment.

// Open the PDF file in which we need to add a Header/Footer
FileStream inStream1 = new FileStream(@"d:/pdftest/2061_11_20090406_233245.pdf", FileMode.Open);

// Create an instance of MemoryStream class
MemoryStream ms = new MemoryStream();
PdfFileStamp fileStamp = null;

fileStamp = new PdfFileStamp(inStream1, ms);

// Create a FormattedText object which will be added to the Header/Footer section
FormattedText ft = new FormattedText("Navigate to Table of Contents (TOC)", System.Drawing.Color.FromArgb(0, 0, 0), Aspose.Pdf.Kit.FontStyle.TimesRoman, EncodingType.Winansi, false, 12);

// Add the Footer section at the specified location in the PDF
fileStamp.AddFooter(ft, 15, 5, 0);

// Add Header section at the specified location in the PDF
fileStamp.AddHeader(ft, 15, 5, 0);

// Close the FileStamp object which adds the watermark to the PDF file
fileStamp.Close();

// Close the input FileStream
inStream1.Close();

// create an object of PDFFileInfo class. We will use it to get the total number of pages in PDF
PdfFileInfo info = new PdfFileInfo(@"d:/pdftest/2061_11_20090406_233245.pdf");

// Create an instance of PdfContentEditor class
PdfContentEditor editor = new PdfContentEditor();

// Create an object of the rectangle that will specify the hyperlink to be added in the Footer section.
System.Drawing.Rectangle Footer_rect = new System.Drawing.Rectangle(5, 12, 180, 15);

// Create an object of the rectangle that will specify the hyperlink to be added in the Header section.
System.Drawing.Rectangle Header_rect = new System.Drawing.Rectangle(5, 760, 180, 15);
editor.BindPdf(ms);

// Set the color value for the rectangle to white that will be displayed around the link
System.Drawing.Color c = System.Drawing.Color.FromArgb(255, 255, 255);

// Iterate through all the pages in the PDF file individually
for (int i = 1; i <= info.NumberofPages; i++)
{
    // Add the local link in the FooterSection of the document.
    editor.CreateLocalLink(Footer_rect, 2, i, c);

    // Add the local link in the HeaderSection of the document.
    editor.CreateLocalLink(Header_rect, 2, i, c);
}

// Save the final PDF with hyperlink & Stamp information
editor.Save(@"d:/pdftest/outfile.pdf");

// Close the memory stream object
ms.Close();
