title: WP7 equivalent of Android 9-patch or iOS UIImage rightCapWidth?
body: <p>I'm working on a WP7 app and can't find any way to stretch an image only at a specific point (repeating that row of pixels). For example, if I have a box with rounded corners I want to stretch it to fill a specific area only I want to stretch just a few pixels in the center (horizontally and vertically) so that the corners are unmodified. </p>
  
  <p>In Android you can do this with a 9 Patch image and in iOS UIImage provides methods such as rightCapWidth.</p>
  
  <p>What's the equivalent for WP7?</p>
  
  <p>Thanks.</p>
