A really neat application! A small notice..in the rectangle the width is written as breadth unlike the other options. Breadth to me sounds like line thickness or something.
I opened a png or gif and upon adding a shape I get this fairly huge warning in console:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

Is a pleasing kind of interface laid out like that to be honest, not cluttered at all.

All new problems require investigation, and so if errors are problems, try to learn as much as you can and report back.
