FPDI_Protection::SetProtection()
Description
class FPDI_Protection extends FPDI {
void SetProtection ( [array $permissions=array()[, string $user_pass=''[, string $owner_pass='']]] ) }
Set the permissions, owner- and userpassword.
If you don't set any password, the document will open as usual. If you set a user password, the PDF viewer will ask for it before displaying the document. The owner password, if different from the user one, can be used to get full access.
Remark: the protection against modification is for people who have the full Acrobat product.
