Remarks
Proper language settings may often improve the recognition results in OCR operations. The language settings affect the character set and the basic vocabulary used in recognition.
Any language code from MFOCRLanguage enumeration (except MFOCRLanguageNone) can be used as a primary language hint. The valid set of secondary language hints depends on the group of the selected primary language hint. The following combination rules apply:
- Languages in group 0 can be combined with any other language.
- Languages in groups 1..6 can be combined with any other language from the same group.
- Languages in groups 1..6 can be combined with any language from the group 0.
- MFOCRLanguageNone can be selected as a secondary language hint, effectively meaning that only the primary language hint is to be used.
The language codes are grouped based on their character sets as follows:
- Group 0
- MFOCRLanguageNeutral
