Сценарий штрих-кода C128 в переполнении стека

Я хочу добавить код 128 авто штрих-код в рамках codeigniter. Я использовал http://davidscotttufts.com/2009/03/31/how-to-create-barcodes-in-php/ для этого, но он генерирует формат code128B. Я также использовал http://www.barcodephp.com/en/download но не может быть в состоянии правильно добавить классы в рамках codeigniter. Кто-нибудь может мне помочь или предложить мне code128 php скрипт автоматического штрих-кода.

заранее спасибо

<?php// Get thickness parameter from $_GET:
$thickness = ( isset( $_GET["thickness"] ) ? $_GET[ "thickness" ] : 2 );

//$text=(int)$text;
$size = (isset($_GET["size"])?$_GET["size"]:"30");
