Steps To Recognize a Form:

1. Create the Master Forms Repository that points to the storage location of the Master Forms.

   			
   RasterCodecs.Startup();
   string root = @"C:\Forms\FormsDemo\OCR_Test";
   RasterCodecs codecs = new RasterCodecs();
   DiskMasterFormsRepository repository = new DiskMasterFormsRepository(codecs, root);
   

2. Create the OCR and Barcode engines to be used in Auto-Forms Engine.

   			
   List<IOcrEngine> ocrEngines = new List<IOcrEngine>();
   IOcrEngine ocrEngine;
   //to use four threads
   int numberOfThreads = 4;
   for(int i = 0; i < numberOfThreads; i++)
   {
       ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Professional, true);
       ocrEngine.Startup(null, null, null, null);
       ocrEngines.Add(ocrEngine);
   }
   BarcodeEngine.Startup(BarcodeMajorTypeFlags.Barcodes1d | 
   BarcodeMajorTypeFlags.Barcodes2dRead | BarcodeMajorTypeFlags.BarcodesDatamatrixRead | 
   BarcodeMajorTypeFlags.BarcodesPdfRead | BarcodeMajorTypeFlags.BarcodesQrRead);
   BarcodeEngine barcodeEngine = new BarcodeEngine();
   

3. Create the Auto-Forms Engine using AutoFormsEngine Class.

   			
   AutoFormsEngine autoEngine = new AutoFormsEngine(repository,ocrEngines,barcodeEngine,30,80, 
   true);
   

4. Recognize the form only.

   			
   AutoFormsRecognizeFormResult result = autoEngine.RecognizeForm(image, null);
