    Watermark annotation allows you to add a text watermark as shown in the picture below:

    You can use the following methods to set the properties of the WatermarkAnnotation class:

    To add a watermark annotation, follow these steps:

    1. Instantiate the Annotator class. Specify the input document path or stream.
    2. Instantiate the WatermarkAnnotation class. Specify the appropriate properties (position, page number, etc).
    3. Call the add() method. Specify the WatermarkAnnotation class.
    4. Call the save() method. Specify the output document path or stream.

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

    // This example demonstrates adding watermark annotation.

// Create an instance of Annotator class
Annotator annotator = new Annotator("inputPath");
try {
    // Create an instance of Reply class and add comments
    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);

    // Create an instance of WatermarkAnnotation class and set options
    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);
    
    // Add annotation and save to file
    annotator.add(watermark);
    annotator.save("outputPath");
} finally {
    if (annotator != null) {
        annotator.dispose();
    }
}
    .
