BarCodeScanner Class
Inherits:Base

Description

BarCodeScanner is used for barcode recognition.

Currently only QR code is enabled. You need to call AttachCamera to attach a CameraDevice to BarCodeScanner first, then the images from the CameraDevice are used for the recognition. You can call Start/Stop to enable/disable the scan process. Start and Stop are very lightweight calls.

You can get a Frame by Augmenter.newFrame which contains current camera image and recognized code string.
