How to clone Image?

You can draw to a buffered image, so make a blank bufferedImage, create a graphics context from it, and draw your original image to it.

BufferedImage copyOfImage = 
   new BufferedImage(widthOfImage, heightOfImage, BufferedImage.TYPE_INT_RGB);
Graphics g = copyOfImage.createGraphics();
g.drawImage(originalImage, 0, 0, null);
