Where mouse.jpg is the picture name you want to add watermark, note that the path name stxinwei.ttf is the path name of the font file file name is a simple test. If you want to adjust the more complex display, you can modify the properties in the class, such as enlargement of fonts can be $ IMG-> WM_TEXT_SIZE = 20; add watermark pictures to $ IMG-> WM_IMAGE_NAME = "file name";
