/**

public static String scanQRImage(Bitmap bMap) {
String contents = null;

    if (bMap.getHeight() > 500 && bMap.getWidth() > 500)
        bMap = Bitmap.createScaledBitmap(bMap, bMap.getWidth() - 300, bMap.getHeight() - 300, false);

    int[] intArray = new int[bMap.getWidth() * bMap.getHeight()];

    //copy pixel data from the Bitmap into the 'intArray' array
    bMap.getPixels(intArray, 0, bMap.getWidth(), 0, 0, bMap.getWidth(), bMap.getHeight());

    LuminanceSource source = new RGBLuminanceSource(bMap.getWidth(), bMap.getHeight(), intArray);
    BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));

    Reader reader = new MultiFormatReader();
    Map<DecodeHintType, Object> tmpHintsMap = new EnumMap<>(
            DecodeHintType.class);
