Select, Copy and Paste Images - H E L P

What I want my app to do:

1 – Select an area of Image and get the coordinates. This code below should do this:

import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import javax.swing.*;

public class ScreenCaptureRectangle {

Rectangle captureRect;

ScreenCaptureRectangle(final BufferedImage screen) {
    final BufferedImage screenCopy = new BufferedImage(
            screen.getWidth(),
            screen.getHeight(),
            screen.getType());
    final JLabel screenLabel = new JLabel(new ImageIcon(screenCopy));
    JScrollPane screenScroll = new JScrollPane(screenLabel);

    screenScroll.setPreferredSize(new Dimension(
            (int)(screen.getWidth()/3),
            (int)(screen.getHeight()/3)));

    JPanel panel = new JPanel(new BorderLayout());
    panel.add(screenScroll, BorderLayout.CENTER);

    final JLabel selectionLabel = new JLabel(
            "Drag a rectangle in the screen shot!");
    panel.add(selectionLabel, BorderLayout.SOUTH);

    repaint(screen, screenCopy);
    screenLabel.repaint();

    screenLabel.addMouseMotionListener(new MouseMotionAdapter() {

        Point start = new Point();

        @Override
        public void mouseMoved(MouseEvent me) {
            start = me.getPoint();
            repaint(screen, screenCopy);
            selectionLabel.setText("Start Point: " + start);
            screenLabel.repaint();
        }

        @Override
        public void mouseDragged(MouseEvent me) {
            Point end = me.getPoint();
            captureRect = new Rectangle(start,
                    new Dimension(end.x-start.x, end.y-start.y));
            repaint(screen, screenCopy);
            screenLabel.repaint();
            selectionLabel.setText("Rectangle: " + captureRect);
        }
    });

    JOptionPane.showMessageDialog(null, panel);

    System.out.println("Rectangle of interest: " + captureRect);
}

public void repaint(BufferedImage orig, BufferedImage copy) {
    Graphics2D g = copy.createGraphics();
    g.drawImage(orig,0,0, null);
    if (captureRect!=null) {
        g.setColor(Color.RED);
        g.draw(captureRect);
        g.setColor(new Color(255,255,255,150));
        g.fill(captureRect);
    }
    g.dispose();
}

public static void main(String[] args) throws Exception {
    Robot robot = new Robot();
    final Dimension screenSize = Toolkit.getDefaultToolkit(). 183 more words
