JAVA code to Add Blind Watermark Verification to PDF
//Source files that need to be watermarked for verification
String file = "template.pdf";
// create an instance of Scene
Scene scene = new Scene();
scene.open(file, FileFormat.PDF);
final String[] text = {null};
//Add password to verify watermark by DecodeWatermark method
try {
scene.getRootNode().accept((Node node) ->
{
Entity mesh = node.getEntity();
if (mesh != null) {
text[0] = com.aspose.threed.Watermark.decodeWatermark((Mesh)mesh, "1234");
