Entry point for performing optical character recognition(OCR) on an input image to detect latin-based characters.

A TextRecognizer is created via getClient(TextRecognizerOptionsInterface). See the code example below.

 TextRecognizer textRecognizer = TextRecognition.getClient(TextRecognizerOptionsInterface);
 

To perform OCR on an image, you first need to create an instance of InputImage from a ByteBuffer, Bitmap, etc. See InputImage documentation for more details. For example, the code below creates an InputImage from a Bitmap.

 InputImage image = InputImage.fromBitmap(bitmap, rotationDegrees); 

Then the code below can detect texts in the supplied InputImage.

 Task<Text> task = textRecognizer.process(image);
 task.addOnSuccessListener(...).addOnFailureListener(...);
