Android Question Problems about scan area with ZbarBarcodeScanner lib


Licensed User
I'working with Johan Schoeman ZbarBarcodeScanner library and I think he did a great job.
I read all forum posts about that library, but I didn't understand the way to modify the area to pick the barcode.
I'm using the ZbarBarcodeScanner lib version 1.03.
I tried in some ways but the area don't change its dimensions.
Can someone help me?
