I am looking a way to define a scan area when user start scanning a sticker(containing QRcode) but getting a difficulty to understand a library.
Actually i want that when scanning done successfully i need to share the image of scanned sticker but problem is that users can scan a QR code by placing a sticker either in middle or any other part of the camera which missed to grab a full sticker image at the end. I want to restrict a user and want to define an area where QR code only start detect for example in bottom right corner of a video. How i can do this ?
