ReceiptRecognitionSettings()

public ReceiptRecognitionSettings()

Default constructor: set autoSkew true.

setLanguage(Language language)

public void setLanguage(Language language)

Parameters:

Parameter	Type	Description
language	Language	Sets the language used for OCR. Multi-language (none) by default.
