Cool. Good luck. Like I said, I hated to be "one of those guys". :) I
just routinely run into "I need to read this JPG, scale it and save it
as PNG" sort of things. I don't know perl well but I do know Java very
well and sometimes I just fire up beanshell(*) and don't even bother to
compile anything. It was just too hard to walk on by.
(*) - BeanShell is a Java-based scripting environment.
