Answer 1

If by work you mean display the BufferedImage on the frame, then that's because there's no code where you're actually adding it to the frame at all!

You may wish to have a look here for some examples of how to do this.

The quickest way would probably be something along the lines of:

JLabel picLabel = new JLabel(new ImageIcon(bI));
pen.add(picLabel);
