I came to this module while searching for a Perl alternative to jpegtran (a UNIX tool). So far I am using it just to remove all metadata for all images during the build-process of a webpage. Works fine!
Once you got the idea and usage of this module, its very simple to use and a real time-saver.
The documentation has been improved recently. As far as I have seen, it is now clear, how to start using this module.
Thanks a lot!
