Usage

From source file:MainClass.java

public void paint(Graphics g) {
    short[] invert = new short[256];

    for (int i = 0; i < invert.length; i++)
        invert[i] = (short) (255 - i);

    BufferedImageOp invertOp = new LookupOp(new ShortLookupTable(0, invert), null);

    BufferedImage clone = invertOp.filter(createImage(), null);

    g.drawImage(clone, 20, 20, this);
