Adobe Acrobat has built in security features that allow restrictions on specific
actions, including selecting text, editing the document, printing, etc... If you open
up the document within Acrobat Exchange (the non-free PDF editor from Adobe) you can
set those security preferences. Unfortunately I've never found a 3rd party program
that lets you set those security preferences, rather odd consider Adobe has opened up
the PDF format.
Antonio, unfortunately the only way I know set the security on a PDF doc at this time
is to buy a copy of Exchange and do it in there.
I haven't tried pdflib, so it's possible that there is an option for the security
settings.
