title: In dompdf what is the "setBasePath" function relative to?
body: <p>I am rendering some html pages in <a href="https://github.com/dompdf/dompdf" rel="nofollow">dompdf</a>. But It doesn't seem to be able to include my images or external css files. If I simply print the page to the screen everything works fine. But dompdf can't find them.</p>
  
  <p>I found a function called: <code>setBasePath</code> where the documentation states "Sets the base path used for external stylesheets and images." Sound like what I want but what is this base path relative too? I tried entering relative to root but it still doesn't find anything.</p>
  
  <pre><code>$dompdf = new Dompdf();
  $dompdf-&gt;loadHtml($template);
  $dompdf-&gt;setBasePath(realpath('./'));
  $dompdf-&gt;render();
  $dompdf-&gt;stream('note');
  </code></pre>
