Public Methods
public Rect getBoundingBox ()
Returns the axis-aligned bounding rectangle of the detected text.
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.
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.
