Yes, that would be it.

I looked in some of the code of umltool and already there noticed that
this is a habit you really need to work on curtailing: whenever you 
start reaching for the copy-paste keys, *FIRST* think whether you could
actually abstract out some of it.

Here, it would probably be a mp->png converter jython module; then
it would be easy to enhance it in *ONE* place, for error detection,
options &c.

Do not take this too harshly: you're doing a very good job. This is
just a small adjustment of direction to make sure the code stays
in a good shape.
