title: usetemplate function in mpdf doesn't working for watermark
body: <p>I tried to add watermark text for everypage of external pdf file. But useTemplate function which doesn't work properly. Here my code:</p>
  
  <pre><code>include('mpdf/mpdf.php');
  $mpdf=new mPDF(''); 
  $mpdf-&gt;SetImportUse(); 
  $pagecount = $mpdf-&gt;SetSourceFile(Yii::app()-&gt;basePath. '/../pdf/'.$model-&gt;file);
  for($i = 1; $i &lt;= $pagecount; $i++){
      $tplId = $mpdf-&gt;ImportPage($i);
      $size = $mpdf-&gt;getTemplateSize($tplId);
  
      $orientation = $size['h'] &gt; $size['w'] ? 'P':'L';
      $mpdf-&gt;AddPage($orientation);
      $mpdf-&gt;useTemplate($tplId, null, null, $size['w'], $size['h'], flase);
      $mpdf-&gt;SetWatermarkText('http://www.bps.go.id','0.07');
      $mpdf-&gt;watermark_font='Arial Black';
      $mpdf-&gt;showWatermarkText = true;
  
  }
  $mpdf-&gt;Output();
  </code></pre>
