title: How to copy an Image/BufferedImage
body: <p>I have a <code>BufferedImage</code>. I want to do two copy of it, to write some things with their Graphics. But, if I <em>write</em> something on one, it will do the same on all the other copy, so I tried to do <code>image.getSubImage(0, 0, image.getWidth(), image.getHeight());</code>, but it doesn't change anything.</p>
  
  <p>I don't know what to do, it would be super to help me.</p>
