IN JAVA LANGUAGE:

Create a new menu item to the project imageviewer1-0 called blur. When this menu item is selected the following code is called:

private void makeBlur() { if(currentImage != null) { // Create the kernel. float filter[] = { 0.1111f, 0.1111f, 0.1111f, 0.1111f, 0.1111f, 0.1111f, 0.1111f, 0.1111f, 0.1111f }; Kernel kernel = new Kernel(3, 3, filter); ConvolveOp op = new ConvolveOp(kernel); // Create the convolve operation. BufferedImage img = op.filter(currentImage, null); currentImage = new OFImage(img); imagePanel.clearImage(); imagePanel.setImage(currentImage); frame.repaint(); showStatus("Applied: blur"); } else { showStatus("No image loaded."); } }
