I am developing an application for scanning code on a scratch card, I do not know how to create a view like this and only scan the scratch card code in that view. I tried it but it scanned all over the screen and I just wanted to scan in a small framecard scan image

    add dark overlay on everything except the part you want to be totally transparent. What exactly is a problem? – Vladyslav Matviienko Aug 27 '18 at 04:53
  • Not only that, I want the camera to scan only in bright areas – Doan Bui Aug 27 '18 at 07:19
  • then you will have to cut that area from the view, and pass the images to your scanning code – Vladyslav Matviienko Aug 27 '18 at 07:20
  • Thanks for your enthusiasm, this problem is very difficult to describe, I have a list of similar tags, I scanned the number on the card, but when scanned it scanned the cards around it, so I Just want to do the view of the camera only scanning one card at a time – Doan Bui Aug 27 '18 at 07:31
