public Rect getBoundingBox ()

public Float getConfidence ()
The confidence of the recognized text.
The value is returned only for cloud recognizers that are configured with
DENSE_MODEL.
public Point[] getCornerPoints ()
Gets the four corner points in clockwise direction starting with top-left. Due to the possible perspective distortions, this is not necessarily a rectangle. Parts of the region could be outside of the image.
The value is only valid for on-device text recognition.
public synchronized List<FirebaseVisionText.Line> getLines ()
Gets an unmodifiable list of
FirebaseVisionText.Lines that make up this text block.
public List<RecognizedLanguage> getRecognizedLanguages ()
Gets a list of recognized languages together with confidence. (Cloud API only.)
public String getText ()
Gets the recognized text as a string. Returned in reading order for the language. For Latin, this is top to bottom within a TextBlock, and left-to-right within a Line.
Returns an empty string if nothing is found.
