i am using mpdf library, it works perfect individuall in an folder on server, but if i include mpdf library in my application, then it output a blank page. if i see the HTML via firebug then display

<html>
       <head></head>
       <body></body>
</html>

below is my page code 

session_start();
error_reporting(-1);    
//include files and mpdf library

$id=(int)$_GET['id'];
//some mysql query and and

$html = "<div id=\"print_target_box\" style=\"display:block;\">";
// some php mysql manipulations
$html .="<b>..</b>
<strong>...</strong><br/>";
// many div and block concatenate by  $html.="";

$html .="</div>";  
$mpdf = new mPDF(); 
$mpdf->debug = true;
$mpdf->WriteHTML($html);
$mpdf->Output();
exit;

    one image `go.gif was missing on server and this does not displaying error
    bcoz error_reporting was set to 0 in below included php page..

    If you edit file mpdf.php and find the line with that error message in it:

    if (!$im) { return $this->_imageError($file, $firsttime, 
    'Error parsing image file - image type not recognised,
      and not supported by GD imagecreate'); }

    change this to:

    if (!$im) { echo $data; exit; }

    it may show what is going wrong.
