title: ZXing.Net.Mobile customising scannable area in xamarin.forms
body: <p>There is an overlay feature available in the library. The overlay feature is nice but functionality wise it is just there to mask the UI.</p>
  
  <p>Is there a way to customize the scannable area, I mean reduce the area that is scannable on the screen? When this can't be done there is no point in having the overlay right? The overlay does not really do anything.</p>
  
  <p>This android app which uses the core Zxing library developed in java by the Zxing team <a href="https://play.google.com/store/apps/details?id=com.google.zxing.client.android" rel="nofollow noreferrer">https://play.google.com/store/apps/details?id=com.google.zxing.client.android</a> you can see that - if the barcode/qr code lies outside the scanning area, it does not process it. That is what I am looking for. Is this possible?</p>
