ZXing convert Bitmap to BinaryBitmap

by

Ok I got it. As Sean Owen said, PlanarYUVLuminaceSource would only be for the default android camera format, which I guess OpenCV does not use. So in short, here is how you would do it:

//(note, mTwod is the CV Mat that contains my datamatrix code)

Bitmap bMap = Bitmap.createBitmap(mTwod.width(), mTwod.height(), Bitmap.Config.ARGB_8888);
Utils.matToBitmap(mTwod, bMap);
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 DataMatrixReader();     
//....doing the actually reading
Result result = reader.decode(bitmap);

So thats it, not hard at all. Just had to convert the Android Bitmap to an integer array, and its a piece of cake.
