Recognition languages

Aspose.OCR for C++ can recognize a text in a large number of languages and all popular writing scripts, including texts with mixed languages.

To specify a language for recognition, provide one of the following values in language_alphabet property in recognition settings:

Value	Language
language::none	Extended Latin characters, including diacritics
language::bel	Belorussian
language::bul	Bulgarian
language::chi	Chinese (more than 6,000 characters)
language::cze	Czech
language::dan	Danish
language::deu	German
language::dum	Dutch
language::eng	English
language::est	Estonian
language::fin	Finnish
language::fra	French
language::hin	Hindi
language::ita	Italian
language::kaz	Kazakh
language::lav	Latvian
language::lit	Lithuanian
language::nor	Norwegian
language::pol	Polish
language::por	Portuguese
language::rum	Romanian
language::rus	Russian
language::slk	Slovak
language::slv	Slovene
language::spa	Spanish
language::srp	Serbian
language::srp_hrv	Serbo-Croatian
language::swe	Swedish
language::ukr	Ukrainian

If this parameter is omitted, the OCR engine will assume that the text is written in extended Latin.

Make sure you specify the correct language for the image. If you try to recognize Cyrillic text using language::Eng, only the characters that look the same in both languages (for example, с and c) will be correctly recognized. Other characters will be replaced with similar-looking alternatives.

Example

The following code sample demonstrates how to specify the recognition language:

std::string image_path = "source.png";
const size_t len = 4096;
wchar_t buffer[len] = { 0 };
RecognitionSettings settings;
settings.language_alphabet = language::ukr;
size_t res_len = aspose::ocr::page_settings(image_path.c_str(), buffer, len, settings);
std::wcout << buffer;
