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();
