[vtkusers] Extract a slice and save it as jpg/png

[Chris Turner]

Hi Bill,

thanks for your answer! But didn't do the trick.
So strange I thought this was a standard question and procedure. And
that there has to be a easy way to do that.

And why don't I even get a error message or something. Even when I
turn on the debug mode there is nothing suspicious.

Anybody has another approach?

Thanks
Chris
