source.url = file.c_str();
std::vector<AsposeOCRInput> content = { source };
// Set recognition language
RecognitionSettings settings;
settings.language_alphabet = language::eng;
// Extract text from the image
auto result = asposeocr_recognize_passport(content.data(), content.size(), settings);
// Output the recognized text
wchar_t* buffer = asposeocr_serialize_result(result, buffer_size, export_format::text);
std::wcout << std::wstring(buffer) << std::endl;
// Release the resources
asposeocr_free_result(result);
Vehicle registration plate recognition

RecognitionSettings settings;
settings.language_alphabet = language::eng;
// Extract text from the image
