How do copy an image from a JComponent?

Question

Hi,
i have a JComponent (in a swing based application) where I draw something on. Now Id like to copy an Image from the JComponent's painting area (no matter if the JComponent is shown or not). How do I get an image of the clipping region?
Is there something like myComponent.getImage(x,y,width,height)?
thanx

Here is some code using the package from the link up above.The code below will get that image and copy it and save that image to a file
import java.awt.*;
import javax.swing.*;
import java.io.*;
import Acme.JPM.Encoders.GifEncoder;
class junk extends JFrame{
public junk() {
  super();
  setSize(400,400);
  setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
  setVisible(true);
public void paint(Graphics g) {
  Image im = createImage(200,200);
  Graphics gg = im.getGraphics();
  gg.fillRect(0,0,200,200);
  g.drawImage(im,0,0,this);
  pgetImage(im);
  public void pgetImage(Image imm){
   try{
   File file = new File("Mypic.gif");
   FileOutputStream out = new FileOutputStream(file);
   GifEncoder cod = new GifEncoder(imm, out);
   cod.encode();
   out.close();
  }catch(Exception oo){oo.printStackTrace();}
public static void main(String agrs[]) {
     junk ji = new junk();
} good luck
