The OCR Advantage engine supports spell checking through language dictionaries. Multiple dictionaries can be used at the same time.
Before calling L_OcrPage_Recognize, set which spell check engine to use by calling L_OcrSpellCheckManager_SetSpellCheckEngine.
To get a list of the dictionaries supported by the LEADTOOLS OCR Advantage engine, call L_OcrSpellCheckManager_GetSupportedLanguages.
