use of com.google.mlkit.vision.text.TextRecognizer in project react-native-camera by lwansbrough.

the class TextRecognizerAsyncTask method doInBackground.

@Override

    if (isCancelled() || mDelegate == null) {
        return null;
    }
    TextRecognizer detector = TextRecognition.getClient(TextRecognizerOptions.DEFAULT_OPTIONS);
    InputImage image = InputImage.fromByteArray(mImageData, mWidth, mHeight, getFirebaseRotation(), InputImage.IMAGE_FORMAT_YV12);
    detector.process(image).addOnSuccessListener(new OnSuccessListener<Text>() {

        @Override

            WritableArray serializedData = serializeEventData(textBlocks);
            mDelegate.onTextRecognized(serializedData);
            mDelegate.onTextRecognizerTaskCompleted();
        }
    }).addOnFailureListener(new OnFailureListener() {
