title: convert html file to pdf using dompdf
body: <p>How do I properly use dompdf to convert html files into pdf. I'm doing something like this:</p>
  
  <pre><code>&lt;?php
  require_once("lib/dompdf/dompdf_config.inc.php");
  
  $file = "checkout.html"; 
  
  $dompdf = new DOMPDF();
  $dompdf-&gt;load_html_file($file);
  $dompdf-&gt;render();
  $dompdf-&gt;stream("sample.pdf");
  
  ?&gt;
  </code></pre>
  
  <p>But I get this error:</p>
  
  <pre><code>Fatal error: Call to undefined method Inline_Frame_Decorator::normalise() in C:\wamp\www\pos\php\lib\dompdf\include\table_frame_decorator.cls.php on line 252
  </code></pre>
  
  <p>How do I solve this, please enlighten me. Thanks.</p>
