title: Get imagery for a rectangle in Google Static Maps API
body: <p>I have two LatLong points: the upper left and bottom right points of a rectangle and I would like, using the Google Maps API, to retrieve satellite imagery for this rectangle.</p>
  
  <p>I understand that since the zoom level is an integer I might not be able to get this exact rectangle but there's no problem if I get a bigger pixmap as long as I am able to calculate the bounding box for the pixmap in latlong coordinates.</p>
  
  <p>Since the pixmap size is fixed (let's say 640x640) and I have it's center, how to find the appropriate zoom level and calculate the bounding box for the pixmap? </p>
