Hello,

I would like to figure out if there is a way to detect with iText whether or
not a document is reader enabled (extended features enabled) and more
importantly if the document has not been modified after that.

So basically I would like to be able to detect the same case than adobe
reader when it gives the following warning:

"This document enabled extended features in Adobe Reader. The document has
been changed since it was created and use of extended features is no longer
available. Please contact the author for the original version of this
document."

Any ideas?
