Return Value

An array of String objects that contain the names of the additional languages supported by the IOcrEngine.


The additional languages are values that are supported by this IOcrEngine but could not be found on the system. You need to install additional language packs to be able to support these languages in your application. For more information, refer to Files to be Included with Your Application.

Use GetSupportedLanguages to get an array of the supported languages by the IOcrEngine.

Use the IsLanguageSupported method to check if an individual language is supported by the IOcrEngine.

The language values used throughout the LEADTOOLS OCR toolkit is a string value based on RFC 4646 (Windows Vista and later). The name could be an ISO 639 two-letter lowercase culture code associated with a language or a combination of ISO 630 and ISO 3166 two-letter uppercase subculture code associated with a country or region.

The language environment defines the character set(s) recognized by the OCR engine. For example, if you enable the English and German languages, the German characters (ä, Ä, é, ö, Ö, ü, Ü, ß) will be combined with the English characters to define the set recognized by the engine. The language environment does not perform spell checking however, for that, refer to IOcrSpellCheckManager.


For an example, refer to IOcrLanguageManager.
