Java Utililty Methods BufferedImage Merge

BufferedImage img = new BufferedImage(800, 600, 1);
Dimension dim = new Dimension(img.getWidth(), img.getHeight());
Graphics g = img.getGraphics();
for (int r = 0; r < dim.width; r++) {
    for (int c = 0; c < dim.height; c++) {
        Color ac = new Color(a.getRGB(r, c));
        Color bc = new Color(b.getRGB(r, c));
        g.setColor(new Color((ac.getRed() + bc.getRed()) / 2, (ac.getGreen() + bc.getGreen()) / 2,
