             Summary: Not able to add watermark in PDF using Overlay
                 Key: PDFBOX-5765
                 URL: https://issues.apache.org/jira/browse/PDFBOX-5765
             Project: PDFBox
          Issue Type: Bug
            Reporter: Tanmay Sharma


I am trying to add watermark to PDF. I am taking following two files as inputs:
 # Original PDF file: To which needs to be added.
 # Watermark PDF File: It is one page PDF in which only contains watermark.

I am trying to combine those files in overlay to generate new document 
containing watermark in it.
{code:java}
PDDocument watermarkDoc = PDDocument.load(new File(".."));
//Assuming your empty document with watermark image in it.

        PDDocument realDoc = PDDocument.load(new File("..."));

        Overlay overlay = new Overlay();
        overlay.setInputPDF(realDoc);
        overlay.setDefaultOverlayPDF(watermarkDoc);
        PDDocument document = overlay.overlay(new HashMap<Integer, String>());
        document.save("...")); {code}
But when I try to open newly generated document in acrobat, though the 
watermark is displayed in the file, but Acrobat is not able to detect it. That 
is I am not able to perform any operation like update or delete watermark.
