Add Named Destinations
This demo adds named destinations to imported PDF files or pages.
These destinations can be compared to anchors in HTML and they can be accessed internally (through e.g. actions) or
by most PDF viewer through the hash of an URL.
PHP
<?php
// load and register the autoload function
require_once __DIR__ . '/../../../../../bootstrap.php';
// display some links to the named destinations to have some interactivity in this demo
if (!isset($_GET['e'])) {
echo '<html><head><link rel="stylesheet" type="text/css" href="' . $basePath . 'layout/demo.css"/></head><body><div id="demoInput">';
foreach (['product-1', 'product-2', 'product-3'] as $destination) {
echo '<a href="?e=1#' . $destination . '" target="pdfFrame">Named Destination "' . $destination . '"</a><br/>';
}
echo '</div><iframe width="100%" name="pdfFrame" src="about:blank"/></body></html>';
