title: com.google.zxing.NotFoundException for all possibility to decode image containing barcode
body: <p>i'm using zxing core and integrated with my android app which takes picture. I'm giving bitmap picture input to RGBLuminanceSource. But every time i'm getting NOTFoundException. I do not want to integrate with zxing barcode scanner via intents or CaptureActivity. Here is the code.</p>
