The "take_barcode" feature using Barcode.take_barcode on an Android invokes a continuous picture scan using the camera (probably it's using the ZXing library behind). The capture area (the rectangle) is however too small. As such the part of the image which is getting processed for barcode is small and of a lower resolution.
Q1. Can it be made configurable or dynamic such that on devices with better camera and display the capture area is larger in width, thereby resulting in a higher resolution image capture and hence quick barcode processing?
Q2. Is there a possibility of configuring the buttons in the UI?
