title: WPF ellipse path
body: <p>I am trying to move an image in wpf. 
  The image should follow an ellipse as a path.
  When the animation is complete, it should start again immediately.
  (for example a planet makes a revolution)</p>
  
  <p>If I am right i should use DoubleAnimation.</p>
  
  <p>The question is what should I write to the DoubleAnimation tag.</p>
  
  <p>Here is the code I wrote so far:</p>
  
  <pre><code>    &lt;Image Source="t:\\moon.jpg" Width="50" Height="50"&gt;
          &lt;Image.Triggers&gt;
              &lt;EventTrigger&gt;
                  &lt;BeginStoryboard&gt;
                      &lt;Storyboard&gt;
                          &lt;DoubleAnimation&gt;
  
                          &lt;/DoubleAnimation&gt;
                      &lt;/Storyboard&gt;
                  &lt;/BeginStoryboard&gt;
              &lt;/EventTrigger&gt;
          &lt;/Image.Triggers&gt;
      &lt;/Image&gt;
  </code></pre>
