The LEADTOOLS CloudServices RecognitionEngine interface provides a high-level method to extract License information from a file. Note, that this method currently only supports United States and EU licenses. The method will return an IDCardResult corresponding to the information extracted from the file.

Code:


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

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

         var licenseInformation = recognitionEngine.ExtractLicense(inputStream, loadOptions, engine, null);
         Console.WriteLine("License ID Number: " + licenseInformation.IDNumber);
         Console.WriteLine("Expiration Date: " + licenseInformation.ExpireDate);
         Console.WriteLine("LIssue Date: " + licenseInformation.IssueDate;
         Console.WriteLine("Country: " + licenseInformation.Country);
         Console.WriteLine("DOB: " + licenseInformation.BirthDate);
