Supported Languages and Language Dictionaries

Show in webframe

Languages can be recognized if the OCR engine supports that language's character set. LEADTOOLS recognizes dozens of languages, enumerated in LANGIDS.

In addition, many recognized languages also have spelling dictionaries, enabling spell-checking after character recognition is complete. Languages for which spell-checking is supported are listed below, along with their associated dictionary file.

OCR Plus

All languages to be recognized can be selected using L_DocSelectLanguages.

The language dictionary to use for spell-checking should be specified in the SpellLangId member of the pRecogOpts parameter passed to the L_DocRecognize function.

For more information on options for the recognition process, refer to RECOGNIZEOPTS.

OCR Professional

All languages to be recognized can be selected using L_Doc2SelectLanguages.

The language dictionary to use for spell-checking should be specified in the SpellLangId member of the pRecogOpts parameter passed to the L_Doc2Recognize function.
