title: mpdf watermark - inclined to vertical
body: <p>I am using mpdf to generate a report in my project. In the report i have to place a watermark. I have placed it using some codes. But the watermark i have got it aligned as 45 degree (do know exactly how much inclined). I want it aligned vertical (90 degree).</p>
  
  <pre><code>$mpdf-&gt;SetWatermarkText('DUMMY');
  $mpdf-&gt;watermark_font = 'DejaVuSansCondensed';
  $mpdf-&gt;showWatermarkText = true;
  $mpdf-&gt;watermarkTextAlpha = 0.15;
  </code></pre>
  
  <p>the above code is what i used.</p>
  
  <p>Does anybody know how to make it vertical?</p>
