Answer 1

I got the solution:

function set_barcode($code)
{
   $this->load->library('zend');
   $this->zend->load('Zend/Barcode');
   $file = Zend_Barcode::draw('code128', 'image', array('text' => $code), array());
   $code = time().$code;
   $store_image = imagepng($file,"../barcode/{$code}.png");
   return $code.'.png';
}

store the image using imgepng function.
it will store the bar code image in barcode folder.
