Stamp Image onto a PDF form
This demo adds a signature image to an existing PDF form while leaving the form fields editable.
PHP
<?php
// load and register the autoload function
require_once __DIR__ . '/../../../../../../bootstrap.php';
// create a writer
$writer = new \SetaPDF_Core_Writer_Http('pdf-form-stamped.pdf', true);
// get a document instance
$document = \SetaPDF_Core_Document::loadByFilename(
$assetsDirectory . '/pdfs/tektown/Order-Form-without-Signaturefield.pdf',
$writer
);
// create a stamper instance
$stamper = new \SetaPDF_Stamper($document);
// get an image instance
$image = \SetaPDF_Core_Image::getByPath($assetsDirectory . '/images/Handwritten-Signature.png');
// initiate the stamp
$stamp = new \SetaPDF_Stamper_Stamp_Image($image);
// set height (and width until no setWidth is set the ratio will retain)
$stamp->setHeight(40);
// add stamp to stamper on position right bottom for page 1 with a specific translation
$stamper->addStamp($stamp, [
'position' => \SetaPDF_Stamper::POSITION_RIGHT_BOTTOM,
'showOnPage' => 1,
'translateX' => -130,
'translateY' => 60
]);
// stamp the document
$stamper->stamp();
// save and send it to the client
$document->save()->finish();
