    //How to create a BufferedImage from a sub rectangle of another BufferedImage, a.k.a. 'clipping'.

    BufferedImage src = ImageIO.read(new File("SomeFile.png"));

    Rectangle clip = new Rectangle((src.getWidth() - 200) / 2, (src.getHeight() - 200) / 2, 200, 200);

    BufferedImage ret = new BufferedImage(clip.width, clip.height, image.getType());

    //short but slow clip and paste :
    ret.getRaster().setRect(-clip.x, -clip.y, image.getData(clip));
    //done !
