FPDI-Protection

Composer version of Setasign FPDI-Protection and FPDF Protection script, _(*1)

This script allows to protect the PDF, that is to say prevent people from copying its content, print it or modify it., _(*2)

Install

composer require madnh/fpdi-protection

USAGE

SetProtection([number permissions [, string user_pass [, string owner_pass]]])

• permissions: the set of permissions. Empty by default (only viewing is allowed).
• user_pass: user password. Empty by default.
• owner_pass: owner password. If not specified, a random value is used.

Permissions

The permission array contains values taken from the following list:, _(*3)

• FPDI_Protection::CAN_PRINT: print the document
• FPDI_Protection::CAN_MODIFY: modify it (except for annotations and forms)
• FPDI_Protection::CAN_COPY: copy text and images to the clipboard
• FPDI_Protection::CAN_ANNOT_FORMS: add annotations and forms

Example

$src_file = 'source.pdf';
$dest_file = 'protected.pdf';

$pdf = new \FPDI_Protection();
$pagecount = $pdf->setSourceFile($src_file);

for ($loop = 1; $loop <= $pagecount; $loop++) {
    $tplidx = $pdf->importPage($loop);
    $pdf->addPage();
    $pdf->useTemplate($tplidx);
}

$pdf->SetProtection(\FPDI_Protection::FULL_PERMISSIONS);
//$pdf->SetProtection(\FPDI_Protection::FULL_PERMISSIONS, '123456');
//$pdf->SetProtection(\FPDI_Protection::FULL_PERMISSIONS, '123456', 'ABCDEF');

$pdf->Output($dest_file, 'F');

IMPORTANT

Some PDF readers like Firefox ignore the protection settings, which strongly reduces the usefulness of this script., _(*4)
