public class Main {

    public static BufferedImage getStrokedImage(
            BufferedImage bi, Shape shape, int strokeWidth) {
        int w = bi.getWidth();
        int h = bi.getHeight();
        BufferedImage bib = new BufferedImage(w,h,bi.getType());
        Graphics2D g = bib.createGraphics();

        BasicStroke bs = new BasicStroke(strokeWidth);
        g.setStroke(bs);
        Rectangle rect = new Rectangle(0,0,w,h); 
        TexturePaint tp = new TexturePaint(bi, rect); 
        g.setPaint(tp);
        g.draw(shape);

        g.dispose();

                        bi.getWidth()-(2*pad),bi.getHeight()-(2*pad)); 
                Image i = getStrokedImage(bi, shape, strokeWidth);
                JOptionPane.showMessageDialog(null, new JLabel(new ImageIcon(i)));
