title: How to calculate the coordinates of the 4 corners (edge) of the map with BingMap?
body: <p>I work with bing from some days. I can display an image with my bing map coordinates lontitude and latitude.</p>
  
  <p>But <strong>I would like to calculate the coordinates</strong> of location in <strong>the 4 edges of my image</strong>.
  For now the only thing I know is the central point of origin.
  The problem is that I'm limited to API. I work for a games xna c # and unfortunately <strong>can not use the Class Map</strong> from microsoft :-(. <a href="http://msdn.microsoft.com/en-us/library/hh846504.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/hh846504.aspx</a></p>
  
  <p><strong>I know the following values:</strong> (sample value)</p>
  
  <p>LevelZoom: 17</p>
  
  <p>ImageWidth: 800 px</p>
  
  <p>Imageheight: 800 px</p>
  
  <p>Lat: 46.6023</p>
  
  <p>Longitude: 7.0964</p>
  
  <p>Is it possible to calculate the coordinates of the 4 corners of my image with these 5 values ​​known? Here is a drawing explaining what I want.
