You can add advanced features like watermarks, annotations, or form fields. For example, you can add a textbox field to a specific coordinate on a page.

php

<?php
// ... Setup code ...
// Create Text form field
$textBoxField = new TextBoxField();
$textBoxField->setPageIndex(1);
$textBoxField->setPartialName("Email");
$rect = new Rectangle();
$rect->setLlx(100);
$rect->setLly(100);
$rect->setUrx(180);
$rect->setUry(120);
$textBoxField->setRect($rect);
// ... Add field to PDF ...
?>
