    g.setColor(Color.WHITE);//from ww  w .  j  av a  2s.  c om
    g.fillRect(0, 0, size, size);
    g.setColor(Color.YELLOW);
    g.fillOval(pad, pad, size - (2 * pad), size - (2 * pad));
    g.dispose();

    BufferedImage image2 = new BufferedImage(bi.getWidth(), bi.getHeight(), BufferedImage.TYPE_BYTE_GRAY);
