Artifact Stamp
A simple demo that shows you how to enclose the stamp content in a marked-content sequence to distinguish it from real content.
PHP
<?php
use setasign\SetaPDF2\Demos\Stamper\Stamp\ArtifactTextStamp;
use setasign\SetaPDF2\Core\Document;
use setasign\SetaPDF2\Core\Font\TrueType\Subset;
use setasign\SetaPDF2\Core\Writer\HttpWriter;
use setasign\SetaPDF2\Stamper\Stamper;
// load and register the autoload function
require_once __DIR__ . '/../../../../../bootstrap.php';
require_once __DIR__ . '/../../../../../classes/Stamper/Stamp/ArtifactTextStamp.php';
// create an HTTP writer
$writer = new HttpWriter('artifact.pdf', true);
//$writer = new \setasign\SetaPDF2\Core\Writer\FileWriter('artifact.pdf');
// let's get the document
$document = Document::loadByFilename(
$assetsDirectory . '/pdfs/Brand-Guide.pdf',
$writer
);
// create a stamper instance
$stamper = new Stamper($document);
//--- Create a text stamp and wrap it in a Tagged stamp instance ---//
// create a font instance which is needed for the text stamp instance
$font = new Subset(
$document,
$assetsDirectory . '/fonts/DejaVu/ttf/DejaVuSans.ttf'
);
// create a stamp instance
$textStamp = new ArtifactTextStamp($font, 10);
// set a text
$textStamp->setText('Personalized for John Dow (jon.dow@example.com)');
// add the stamp to the stamper instance
$stamper->addStamp($textStamp, [
'position' => Stamper::POSITION_CENTER_TOP,
'translateX' => 2,
'translateY' => -2
]);
// execute the stamp process
$stamper->stamp();
// save and finish the document instance
$document->save()->finish();
