title: How to display original image size in openseadragon?
body: <p>I am trying to implement openseadragon zoom plugin in my angular4 application.</p>
  
  <p>Everything is working but i can't able to show the original image size,openseadragon is restricting image size and setting image in center if i use like below,</p>
  
  <pre><code>const viewer = OpenSeadragon({
              id                 : 'seadragon-viewer',
              prefixUrl          : '//openseadragon.github.io/openseadragon/images/',
              tileSources        : this.primaryPicture.hiResInformation,
              showFullPageControl: false,
              showNavigator      : true,
              homeFillsViewer    : false,
          });
  </code></pre>
  
  <p>If i use <code>homeFillsViewer    : true</code> then image is fitting into the div but image is not proper like cropped image.</p>
  
  <p>I want to display original size of image.</p>
  
  <p>Any solutions will be helpful, thank you in advance.</p>
