Solution

  • I am referring to this answer. Have a look. Modifying existing pdf file using iText 5.5.13.2 is complicated. But the referred solution is more easier. iText 7 has handier way to modify existing pdf. There are several other ways. Like PdfStamper etc.

    From referred answer, add following code to make an anchor.

    Phrase phrase = new Phrase("Open ");
Phrase phrase1 = new Phrase(" on Click On it.");

Font anchorFont = new Font(Font.FontFamily.UNDEFINED, 11);
anchorFont.setColor(BaseColor.BLUE);
anchorFont.setStyle(Font.FontStyle.UNDERLINE.getValue());

Anchor anchor = new Anchor("Google", anchorFont);
anchor.setReference("www.google.com");

phrase.add(anchor);
phrase.add(phrase1);
document.add(phrase);

    Change the font and colors based on your needs.

    Full code:

    try {
    PdfReader reader = new PdfReader("test.pdf"); //src pdf path (the pdf I need to modify)

    Document document = new Document();
    PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("test2.pdf")); // destination pdf path
    document.open();

    PdfContentByte cb = writer.getDirectContent();
    PdfImportedPage page = writer.getImportedPage(reader, 1);

    document.newPage();
    document.setPageSize(reader.getPageSize(1));

    cb.addTemplate(page, 0, 0);

    Phrase phrase = new Phrase("Open ");
    Phrase phrase1 = new Phrase(" on Click On it.");
    Font anchorFont = new Font(Font.FontFamily.UNDEFINED, 11);
    anchorFont.setColor(BaseColor.BLUE);
    anchorFont.setStyle(Font.FontStyle.UNDERLINE.getValue());

    Anchor anchor = new Anchor("Google", anchorFont);
    anchor.setReference("https://www.google.com");

    phrase.add(anchor);
    phrase.add(phrase1);
    document.add(phrase);

    document.close();

    } catch (IOException e) {
        e.printStackTrace();
    } catch (DocumentException e) {
        e.printStackTrace();
    }
}
