Manual Installation

If you do not use composer, just require the autoload.php in the /src folder:, _(*5)

require_once('src/autoload.php');

If you have a PSR-4 autoloader implemented, just register the src path as follows:, _(*6)

$loader = new \Example\Psr4AutoloaderClass;
$loader->register();
$loader->addNamespace('setasign\FpdiProtection', 'path/to/src/');

Don't forget to install FPDI and FPDF, too!, _(*7)

Example

This class offers one public method, which allows you to set the protection of the resulting PDF document. All other code is identically to FPDI or FPDF., _(*8)

If you pass null or an empty string as the owner password the method will create a random owner password. The return value of this method is the owner password., _(*9)

<?php
use setasign\FpdiProtection\FpdiProtection;

// setup the autoload function
require_once('vendor/autoload.php');

$pdf = new FpdiProtection();
$ownerPassword = $pdf->setProtection(
    FpdiProtection::PERM_PRINT | FpdiProtection::PERM_COPY,
    'the user password',
    'the owner password'
);
