Can you optimize this code with bit shifting?

Question

Hi there,
I was wondering if anyone could make this code run faster, by implementing bitshifting techniques. I'd really appreciate it, and thanks!
    public void scaleImage(Image source, Image dest) { 
        int sourceWidth = source.getWidth();
        int sourceHeight = source.getHeight();
        int thumbWidth = dest.getWidth();
        int thumbHeight = dest.getHeight();
        Graphics g = dest.getGraphics();
        int dx, dy = 0;
        for (int y = 0; y < thumbHeight; y++) {
            for (int x = 0; x < thumbWidth; x++) {
                g.setClip(x, y, 1, 1);
                dx = x * sourceWidth / thumbWidth;
                dy = y * sourceHeight / thumbHeight;
                g.drawImage(source, x - dx, y - dy, Graphics.LEFT | Graphics.TOP);

your method reminds me this stuff:
