Advanced Styling
This demo shows you how you can style the rich-text stamp in view to colors, background and borders.
PHP
<?php

$assetsDirectory . '/pdfs/Brand-Guide.pdf',

$fontLoader = new \com\setasign\SetaPDF\Demos\FontLoader($assetsDirectory);
// create a rich-text stamp instance
$stamp = new \SetaPDF_Stamper_Stamp_RichText($document, $fontLoader);
$stamp->setDefaultFontFamily('DejaVuSans');
$stamp->setText('Personalized for <b style="color:#0f0f0f;">john@example.com</b>');
// set the border color to gray (e.g. as a hex value)
$stamp->setBorderColor('#c7c7c7');
// and width
$stamp->setBorderWidth(1);
// set background color to light-gray (e.g. as an array of RGB values (0 - 1)
$stamp->setBackgroundColor([.95, .95, .95]);
// set padding
$stamp->setPadding(3);
// set default text color by an explicit color instance
$stamp->setDefaultTextColor(new \SetaPDF_Core_DataStructure_Color_Rgb(56/255, 101/255, 174/255));
// add the stamp to the stamper instance
$stamper->addStamp($stamp, [
'position' => \SetaPDF_Stamper::POSITION_CENTER_BOTTOM,
'translateY' => 15
]);
// stamp the document with all previously added stamps
$stamper->stamp();
// save and finish the document instance
$document->save()->finish();
