You need to call Image.scaleToFit() (or a similar method) giving the
image size in 72dpi. The original image will retain the full

The nice thing about using getters/setters is that code completion

but using

My point was, if you use the standard Java interfaces, a user that is
running Java 1.3 or 1.4 can install the bouncy castle "provider" jars
and it will work.
A user that is running 1.5 does not need the bouncy castle jars since
the provider is already there.
With the current code, all users
do this as long as there is some reasonable
