    BufferedImage bi = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);

    Graphics2D ig2 = bi.createGraphics();
    ig2.fillRect(0, 0, width - 1, height - 1);

    BasicStroke stroke = new BasicStroke(10, BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND);
    ig2.setPaint(Color.lightGray);
    ig2.setStroke(stroke);//from w ww. ja  v  a  2  s .  c o  m
    ig2.draw(new Ellipse2D.Double(0, 0, 100, 100));
