title: How to generate thumbnails for images stored on the server using dropzone?
body: <p>I'm trying to display images already stored on the server. I display in dropzone, using the following code:</p>
  
  <pre><code>myDropzone.emit("addedfile", mockFile);
  myDropzone.emit("thumbnail", mockFile, "url/image");
  </code></pre>
  
  <p>But with a problem, the thumbnail generated only reduces the size to thumnail sizes as specified without crop.</p>
  
  <p>The problem is this is not done the crop image when I call the function thumbnail image is distorted.</p>
  
  <p>It would be possible to generate a temporary thumbnail using existing methods and sends it in the thumbnail function call?</p>
