Graphics problem , how to approach ?

[Tirthankar Mukherjee]

I am trying to repaint a component. Putting a image on a panel the applying graphics change in it (like drawing polygon, rectangle ..).

 protected  void paintComponent(Graphics g)   

I would like to take the backup of the image passed to the class, and restore the graphics of the Component on need.

Problems I am facing :

1) Cannot make a clone for Image class.
2) Taking the backUp in BufferedImage using

   
 imageBackUp = new BufferedImage(WIDTH, HEIGHT, BufferedImage.TYPE_INT_RGB);
 imageBackUp.setData(((BufferedImage)originalImage).getData());

3) Trying to restore the image with

  originalImage = (Image)imageBackUp;  

seems not working.

NB : repaint() is always there.

Thanks in advance.

drawImage(..) the original image to the Graphics context of the backup image.

You do realize that after that line executes, you have two references to the same BufferedImage, don't you?

Also, I can't see why a cast to Image would be needed. What's the Type of imageBackUp?
