title: How to add graphics on top of a multiscaleimage?
body: <p>I want to add graphics to a multiscaleimage. I use the project that Deep Zoom Composer auto generated when creating a multiscaleimage. Displaying the multiscaleimage from VS2008 works.</p>
  
  <p>I've tried this and added the graphics to the maincanvas, without any results:</p>
  
  <pre><code>&lt;Grid&gt;
   &lt;Canvas Name="maincanvas"/&gt;
   &lt;MultiScaleImage/&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p>Edit: When the user zooms in on the multiscaleimage, the user can place geometrically figures on the image. E.g. place a rectangle next to a person in the image, which will act as a speech balloon. I know this can be done on the image before the image is scaled, but I would like to do it dynamically.</p>
