How to generate barcode image in Codeigniter?

Question

How can I print a barcode image with CodeIgniter?

Do I have to make a custom library or helper to generate a barcode image? Does anyone know any library or helper to generate a barcode image in CodeIgniter?

This thread on the CodeIgniter forum suggests using the Zend Barcode class. From that thread:

function barcode()
{
    $this->load->library('zend');
    $this->zend->load('Zend/Barcode');

    Zend_Barcode::render('code39', 'image', array('text' => 'CodeIgniter Rocks'), array());
}
