I need to create a language selector for OCR processing of documents. I can list all available languages getting them from engine.PredefinedLanguages and i can narrow the list by showing only a specific subset with a specific FREngine.LanguageCategoryEnum (like core languages).
However this list is not relative to current license available languages. In current license there is a bitmapped field named AvailableLanguageSetsFlags which defines the subsets available but I haven't understood how (and if) I can use this information to filter only available languages.
Is there a way to show only languages available with currently loaded license?
