Question

How do i add an image on the last page of existing PDF document. Please help me.

Answer 1

You can read the text from the PDF using the same ITEXT library.Try this

    PdfReader reader = new PdfReader(INPUTFILE);
    int n = reader.getNumberOfPages();
    PdfTextExtractor parser =new PdfTextExtractor(new PdfReader("C:/Text.pdf"));
    parser.getTextFromPage(3); // Extracting the content from a particular page.

After you have add your data ,You can load images either from file or from a URL, like this:

   Image image1 = Image.getInstance("watermark.png");
   document.add(image1);

   String imageUrl = "http://applause-voice.com/wp-content/uploads/2011/04/1hello.jpg";
   Image image2 = Image.getInstance(new URL(imageUrl));
   document.add(image2);

If you will add this code at the end of your Java Program , then the image will automatically comes at the end of your page.
