title: Drawing basic shapes on an image in a Windows Phone 8 app
body: <p>How can I draw basic shapes on an image in a WP8 app depending on where the user touches the image</p>
  
  <p>Example:</p>
  
  <p>User takes a photo using the camera, it appears in the app (currently using an image control for this), then the user touches a point on the image and a fixed size circle or rectangle appears there. I should be able to store the location of the rectangle and display the rectangle.</p>
