Follow these steps to add Watermark annotation to document: 

The following code demonstrates how to add WatermarkAnnotation to the document:

String outputPath = Constants.getOutputFilePath("AddWatermarkAnnotation", FilenameUtils.getExtension(Constants.INPUT));
            final Annotator annotator = new Annotator(Constants.INPUT);
            try {
                Reply reply1 = new Reply();
                reply1.setComment("First comment");
                reply1.setRepliedOn(Calendar.getInstance().getTime());
                Reply reply2 = new Reply();
                reply2.setComment("Second comment");
                reply2.setRepliedOn(Calendar.getInstance().getTime());
                java.util.List<Reply> replies =  new ArrayList<Reply>();
                replies.add(reply1);
                replies.add(reply2);
                WatermarkAnnotation watermark = new WatermarkAnnotation();
                watermark.setAngle((double) 75);
                watermark.setBox(new Rectangle(200, 200, 100, 50));
                watermark.setCreatedOn(Calendar.getInstance().getTime());
                watermark.setText("Watermark");
                watermark.setFontColor(65535);
                watermark.setFontSize((double) 12);
                watermark.setMessage("This is watermark annotation");
                watermark.setOpacity(0.7);
                watermark.setPageNumber(0);
                watermark.setReplies(replies);
                annotator.add(watermark);
                annotator.save(outputPath);
            } finally {
                if (annotator != null) {
                    annotator.dispose();
                }
            }
