Hello:
I have updated the example and documentation (on my portal) because I have added PDF generated documents the electronic signature functionality of these documents.

This signature of PDF documents adds, among many other features:

• Identity of the person / company that the document has made. Only those who have the signature are true.
• The document can not be modified.

In summary, it gives guarantees to the two parties.

Greetings,
fernando
