AutoFormsProgressEventArgs Class

Summary
Reports the progress for specific AutoFormsEngine operations and offers the user an opportunity to cancel.

Syntax
C#
C++/CLI
Java
Python
public class AutoFormsProgressEventArgs : EventArgs 
public class AutoFormsProgressEvent 
    extends leadtools.LeadEvent 
public ref class AutoFormsProgressEventArgs : public System.EventArgs  
class AutoFormsProgressEventArgs(EventArgs): 
Remarks

This event is fired when recognizing and processing a form, or when generating form attributes. The Percentage Property is not meaningful during recognition operations since the engine does not necessarily need to compare the filled form with each master form in the repository. Once the engine finds a match, it will stop searching and return.

This event also allows the user to cancel engine operations using the Cancel property

Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Forms.Common; 
using Leadtools.Forms.Auto; 
using Leadtools.Document; 
using Leadtools.Ocr; 
using Leadtools.Forms.Recognition; 
using Leadtools.Forms.Processing; 
using Leadtools.Barcode; 
 
 
public void MyProgressEvent(object sender, AutoFormsProgressEventArgs e) 
{ 
   Console.WriteLine("Operation: {0}  {1}%", e.Operation, e.Percentage); 
} 
public void AutoFormRecognitionAndProcessing1() 
{ 
   string root = Path.Combine(LEAD_VARS.ImagesDir, @"Forms\FormsDemo\OCR_Test"); 
   RasterCodecs codecs = new RasterCodecs(); 
   //create repository 
   DiskMasterFormsRepository repository = new DiskMasterFormsRepository(codecs, root); 
 
   using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD)) 
   { 
      ocrEngine.Startup(null, null, null, LEAD_VARS.OcrLEADRuntimeDir); 
 
      BarcodeEngine barcodeEngine = new BarcodeEngine(); 
 
      AutoFormsEngine autoEngine = new AutoFormsEngine(repository, ocrEngine, barcodeEngine, 30, 80, true); 
      autoEngine.Progress += MyProgressEvent; 
 
      //Load the first page of the for, 
      RasterImage form = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"Forms\Forms to be Recognized\OCR\FCC-107_OCR_Filled.tif"), 
                                     1, CodecsLoadByteOrder.Bgr, 1, 1); 
      //recognize the form 
      AutoFormsRecognizeFormResult result = autoEngine.RecognizeForm(form, null); 
      if (result == null) 
         return; 
      //check if we have all pages 
      if (form.PageCount != result.Properties.Pages) 
      {//load the remaining pages of the form 
         form.AddPages(codecs.Load(FormFileName, 1, CodecsLoadByteOrder.Bgr, 2, -1), 1, -1); 
      } 
      //get form fields 
      FormPages formFields = result.MasterForm.ReadFields(); 
      FormRecognitionAttributes attributes = result.MasterForm.ReadAttributes(); 
      //process form 
      autoEngine.ProcessForm(form, null, null, attributes, formFields); 
   }
