With JDIC WebBrowser, how to save the content as an image ?

Question

I wonder if there is a way to save the WebBrowser's content (Html page with graphics) into a *.png image file ? The html page may span several screens, if I do a screen shot, I can only get the top part which I can see, but will miss the off screen contents. What I mean is : if the page is 900(W) x 3500(H) pixels, how to ask my java program to take a screen shot which can get the whole image of the WebBrowser content, including those off the bottom of the screen ?
I was able to do this with the following method for JComponent
  public static BufferedImage Get_JComponent_Image(JComponent J_Component,Rectangle region) throws IOException   // Create a BufferedImage for Swing components. All or part of the component can be captured to an image.
   /* @param J_Component Swing component to create image from
    * @param region The region of the component to be captured to an image
    * @return image the image for the given region
    * @exception IOException if an error occurs during writing
    boolean opaqueValue=J_Component.isOpaque();
    J_Component.setOpaque(true);
    BufferedImage image=new BufferedImage(region==null?J_Component.getWidth():region.width,region==null?J_Component.getHeight():region.height,BufferedImage.TYPE_INT_RGB);
    Graphics2D g2d=image.createGraphics();
    g2d.setClip(region);
    J_Component.paint(g2d);
    g2d.dispose();
    J_Component.setOpaque(opaqueValue);
    return image;
  }So I tried to modify this method to work for Component (since WebBrowser is a sub-class of it), I got black screen with the following modified method :
  public static BufferedImage Get_Component_Image(Component A_Component,Rectangle region) throws IOException   // Create a BufferedImage for Swing components. All or part of the component can be captured to an image.
   /* @param A_Component AWT component to create image from
    * @param region The region of the component to be captured to an image
    * @return image the image for the given region
    * @exception IOException if an error occurs during writing
    boolean opaqueValue=A_Component.isOpaque();
    Out("opaqueValue="+opaqueValue);
//    A_Component.setOpaque(true);
    BufferedImage image=new BufferedImage(region==null?A_Component.getWidth():region.width,region==null?A_Component.getHeight():region.height,BufferedImage.TYPE_INT_RGB);
    Graphics2D g2d=image.createGraphics();
    g2d.setClip(region);
    A_Component.paint(g2d);
    g2d.dispose();
//    A_Component.setOpaque(opaqueValue);
    return image;
  }Can anyone tell me what I did wrong ? Thanks.

Hi,
Even im looking for the same thing. I tried createImage on the panel but its giving me a blank screenshot, which i presume does not works on the embedded IE area and gives the blank screenshot of the jPanel behind it.
Kindly post any solution you might have come up with.
Thanx
