title: ZXingScannerView in the ZXing.Net.Mobile library
body: <p>I'm trying to have a custom view in ZXingScannerView of my Xamarin project. The goal is to have to a Target Area (A red Square) so that the end user can focus on the QR Code and a cancel button within the ZXingScannerView, to end the scanning activity.</p>
  
  <p>Any ideas?</p>
