public class StampOp extends AbstractBufferedImageOp
StampOp
is an image operation, which may scale the source
image to the destination image and put a stamp mark ontop of the (scaled)
destination image. The location and size as well as the mark it self must be
provided to the operation before the filter
method is called.
The operation can be reused to stamp multiple images.
Sample use:
// create op with no rendering hints StampOp op = new StampOp(); // set the stamp image op.setStamp(watermarkImage); // set the top,left location, default is (0, 0) op.setStampLocation(20, 20); // set the stamp size, default is (15, 15) op.setStampSize(30, 30); // draw stamp with 50% opacity (default is 100% opacity) op.setStampComposite(AlphaComposite.getInstance(AlphaComposite.SRC, 0.5f)); // apply the stamp stampedImage = op.filter(rawImage, null);
