Public Methods

public Rect getBoundingBox ()

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

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.Line> getLines ()

Gets an unmodifiable list of Text.Lines that make up this text block.

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.TextBlock. It concatenates text strings from underlying Text.Lines separated by '\n'.

The recognized text is 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.
