title: Custom Xaml crop control for windows phone 8.1
body: <p>I am writing a <strong>Windows Phone 8.1</strong>  app that requires me to <strong>crop</strong> an image to produce another square image <strong>(250 by 250)</strong>. I need <strong>xaml and code behind sample code</strong> that I can be use to do the cropping. The examples found online are for the <strong>old</strong> WP8 and they are not very helpful.Any assistance will be appreciated. </p>
