//        int y = 100;
//        int width = 400;
//        int height = 400;
//        area = new Rectangle(x, y, width, height);
//        screenShot=ScreenShotPanel.captureImage(area);
        
        // Capture the whole screen
        area = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
        screenShot=ScreenShotPanel.captureImage(area);
    }
    
    
    public static Image captureImage(Rectangle area){
        Image img=null;
        try{
            Robot robot = new Robot();
            img = (Image)robot.createScreenCapture(area);   
        }
        catch(Exception e){
            System.out.println(e);
        }
        return img;
    }
    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.drawImage(screenShot, 0, 0, null);
    }
    public static void main(String []nix){
        ScreenShotPanel screenShotPanel=new ScreenShotPanel();
        JFrame screenShotFrame=new JFrame();
        screenShotFrame.add(screenShotPanel);
        screenShotFrame.setSize(800, 800);
        screenShotFrame.setVisible(true);
        screenShotFrame.setTitle("Capturing a Screen Shot - Tutorial Jinni");
        screenShotFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
