Question
How to set several recognition languages in FineReader Engine?
Answer
Call the SetPredefinedTextLanguage method of the RecognizerParams object with names separated with commas, for example:
// C#
DocumentProcessingParams documentProcessingParams = Engine.CreateDocumentProcessingParams();
PageProcessingParams pageProcessingParams = documentProcessingParams.PageProcessingParams();
RecognizerParams recognizerParams = pageProcessingParams.RecognizerParams();
recognizerParams.SetPredefinedTextLanguage("English, French, German");
