title: Pixel Compare excessive zoom
body: <p>I'm working with Pixel Compare extension. It works well with rvt files, and almost with pdfs.
  When comparing two pdf, the viewer will zoom in on a part of the file and i'm unable to unzoom it.
  Furthermore, it appears the original file is reduced to the zoomed part.</p>
  <p>Examples:</p>
  <p><a href="https://i.stack.imgur.com/fLW9q.png" rel="nofollow noreferrer">Heres the file before comparing :</a></p>
  <p><a href="https://i.stack.imgur.com/jbp8d.png" rel="nofollow noreferrer">And then after, it zooms on the left corner. I cannot access the rest of the file nor zoom out.</a></p>
  <p>I looked for zooming properties on the api docs, but found nothing.
  Ive honestly no idea what causes it and would welcome any pointer in the right direction.</p>
  <p>Thanks in advance.</p>
  <p>Edit:</p>
  <p>I load pdf this way , Autodesk.Viewing.Initializer not pictured:</p>
  <pre><code>viewer1.addEventListener(Autodesk.Viewing.LOADER_LOAD_FILE_EVENT, function (e) {
                          viewer1.loadExtension('Autodesk.PDF').then(() =&gt; {
                      
                          viewer1.loadExtension(&quot;Autodesk.Viewing.MarkupsCore&quot;);
                          viewer1.loadExtension(&quot;Autodesk.Viewing.MarkupsGui&quot;);
                          
                          
                      });
              });
  </code></pre>
