body: <p>I'm using Snappy Bundle along with Symfony 2.1.</p>
  
  <p>I have some question I did not find in the documentation of this bundle :</p>
  
  <ul>
  <li>How to set the orientation ?</li>
  <li>Is there a way to display page numbers ?</li>
  </ul>
  
  <p>Here is my config.yml for the bundle :</p>
  
  <pre><code>knp_snappy:
      pdf:
          enabled:    true
          binary:     /home/wkhtmltopdf-i386
          options:    []
  </code></pre>
  
  <p>Here is one of my Controller to generate a pdf :</p>
  
  <pre><code>public function exampleAction() {
      $html = $this-&gt;renderView('MyBundle:Example:test.pdf.twig', $this-&gt;param);  
      return new Response($this-&gt;get('knp_snappy.pdf')-&gt;getOutputFromHtml($html),200, array(
      'Content-Type'          =&gt; 'application/pdf',
      'Content-Disposition'   =&gt; 'attachment; filename="Test.pdf"'));
  
  } 
  </code></pre>
  
  <p>Thanks a lot for your help!</p>
