Different Font-Styles
A simple demo showing the usage of different font styles (bold, italic, underline) with the use of a rich-text stamp.
PHP
<?php
// load and register the autoload function
require_once __DIR__ . '/../../../../../../bootstrap.php';
// create a writer
$writer = new \SetaPDF_Core_Writer_Http('styled.pdf', true);
// get a document instance
$document = \SetaPDF_Core_Document::loadByFilename(
$assetsDirectory . '/pdfs/lenstown/Laboratory-Report.pdf',
$writer
);
/* Font styles are done by using different font programs for each style. To
* benefit from font subsetting, we need to create a callback that will create
* the right font instances for us. See FontLoader.php for details:
*/
require_once $classesDirectory . '/FontLoader.php';
$fontLoader = new \com\setasign\SetaPDF\Demos\FontLoader($assetsDirectory);
// now simply create a stam instance
$stamp = new \SetaPDF_Stamper_Stamp_RichText($document, $fontLoader);
$stamp->setDefaultFontFamily('DejaVuSans');
$stamp->setDefaultFontSize(10);
// pass an HTML like text to format the output
$stamp->setText(<<<HTML
This document is licensed to <b><u>test@example.com</u></b> and was created on <i>www.setasign.com</i>.
HTML
);
// create a stamper instance
$stamper = new \SetaPDF_Stamper($document);
// pass the stamp instance
$stamper->addStamp($stamp, [
'position' => \SetaPDF_Stamper::POSITION_CENTER_TOP,
'translateY' => -5
]);
// stamp the document
$stamper->stamp();
// save and send it to the client
$document->save()->finish();
