possible restrictions to PDF?

[allanh]

Hello everyone!
Congratulations on your work.
I was wondering if you could do something.
allow restrictions to pdf.
as: printing, etc. modify document?
It is possible?
Thank you.

If you're using the CPDF back end you would do something like the following:

$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->get_canvas()->get_cpdf()->setEncryption('userpass', 'ownerpass', array('print'));
$dompdf->stream('protected.pdf');

userpass/ownerpass are the passwords for opening the document. If you leave the owner password blank it will be set to the same as user password. The options available for the user permission array are: print, modify, copy, add.

I should note that there is a bug that needs to be addressed that may affect the appearance of your PDF when you're using embedded fonts. You can watch for a resolution in the issue tracker.
