An array of recognized languages in the text line. On-device text recognizers only detect
Latin-based languages, while cloud text recognizers can detect multiple languages. If no
languages are recognized, the array is empty.
The four corner points of the text line in clockwise order starting with the top left point
relative to the image in the default coordinate space. The NSValue objects are CGPoints. For
cloud text recognizers, the array is nil.
The confidence of the recognized text line. The value is nil for all text recognizers except
for cloud text recognizers with model type VisionCloudTextModelType.dense.
