The LEADTOOLS CloudServices RecognitionEngine interface provides a high-level method to extract passport information from a file. The ExtractPassport method returns a dictionary containing all of the information that was extracted from the input stream.


         var inputStream = File.Open(@"leadtools.pdf", FileMode.Open);
         var loadOptions = new LoadDocumentOptions()
            FirstPageNumber = 1,
            LastPageNumber = 1

         var recognitionEngine = new RecognitionEngine();
         IOcrEngine engine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD, false);
         engine.Startup(null, null, null, @"path/to/OCR Bin Directory");

         var passportInformation = recognitionEngine.ExtractPassport(inputStream, loadOptions, engine, null);
         foreach(var info in passportInformation)
            Console.WriteLine("Key:" + info.Key);
            Console.WriteLine("Value:" + info.Value);
