Public Methods

public float getAngle ()

Gets the angle(in degrees, clockwise is positive, range is [-180, 180]) of the rotation of the recognized line.

public Rect getBoundingBox ()

Returns the axis-aligned bounding rectangle of the detected text. If nothing found, it returns null.

public float getConfidence ()

Gets the confidence of the recognized line.

It is in range [0.0f, 1.0f].

Note that this information will be unavailable (i.e. returns 0) if you're using the unbundled version of Text Recognition library with an older version of Google Play services (lower than 22.30.XX).

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. If nothing found, it returns null.

public synchronized List<Text.Element> getElements ()

Gets a unmodifiable list of Text.Elements that make up this text line.

Returns an empty list if nothing is found.

public String getRecognizedLanguage ()

Gets prevailing language in the text, if any. The format is in BCP47 (e.g. "en" or "sr-Latn-BA") or "und" if the language could not be determined.

public String getText ()

Gets the recognized text in the Text.Line. It concatenates text strings from underlying Text.Elements separated by white spaces.

The recognized text is in reading order for the language. For Latin, it is left-to-right within a Line.

Returns an empty string if nothing is found.
