    <title>Save Changes to PDF Documents</title>
    <para>
    There are two methods that save changes to PDF documents: the <classname>Zend_Pdf::save()</classname> and
    <classname>Zend_Pdf::render()</classname> methods.
    </para>

    <para>
    <classname>Zend_Pdf::save($filename, $updateOnly = false)</classname> saves the PDF document to a file. If $updateOnly
    is true, then only the new PDF file segment is appended to a file. Otherwise, the file is overwritten.
    </para>

    <para>
    <classname>Zend_Pdf::render($newSegmentOnly = false)</classname> returns the PDF document as a string. If
    $newSegmentOnly is true, then only the new PDF file segment is returned.
    </para>
