Step 4: Add an Image Stamp

To add an image stamp to the PDF document, you’ll need an image file to use as the stamp. Here’s how you can do it:

// Code to add an image stamp
Stamp stamp = new Stamp();
stamp.bindImage("path/to/your/image.png");
pdfDocument.getPages().get_Item(1).addStamp(stamp);

Step 5: Customize the Image Stamp

You can customize the appearance and position of the image stamp according to your requirements. Adjust the opacity, size, rotation, and other properties as needed.

Step 6: Save the PDF Document

After adding the image stamp, save the modified PDF document to a file.

// Code to save the PDF document
pdfDocument.save("output.pdf");
