using Leadtools.Forms.Recognition; 
using Leadtools.Codecs; 
 
///This method will pass  attributes to recognize form. 
public FormRecognitionResult CompareFormsWithMastersFast(RasterImage filledFormImage, List<FormRecognitionAttributes> mastersAttributes, FormRecognitionEngine engine) 
{ 
   FormRecognitionOptions formOptions = new FormRecognitionOptions(); 
   // We will use Simple (fast) method to create form to use it with CompareFormFast  method 
   formOptions.RecognitionMethod = FormsRecognitionMethod.Simple; 
   FormRecognitionAttributes filledAttribute = engine.CreateForm(formOptions); 
   PageRecognitionOptions pageOptions = new PageRecognitionOptions(); 
   pageOptions.AutoCleanUp = true; 
   pageOptions.UpdateImage = true; 
 
   engine.AddFormPage(filledAttribute, filledFormImage, pageOptions); 
   engine.CloseForm(filledAttribute); 
 
   filledAttribute.Image = filledFormImage; 
 
   return engine.CompareFormFast(mastersAttributes, filledAttribute, null); 
}

Imports Leadtools.Forms 
Imports Leadtools.Forms.Recognition 
Imports Leadtools.Codecs 
 
'''This method will pass  attributes to recognize form. 
Public Function CompareFormsWithMastersFast(filledFormImage As RasterImage, mastersAttributes As List(Of FormRecognitionAttributes), engine As FormRecognitionEngine) As FormRecognitionResult 
   Dim formOptions As New FormRecognitionOptions() 
   ' We will use Simple (fast) method to create form to use it with CompareFormFast  method 
   formOptions.RecognitionMethod = FormsRecognitionMethod.Simple 
   Dim filledAttribute As FormRecognitionAttributes = engine.CreateForm(formOptions) 
   Dim pageOptions As New PageRecognitionOptions() 
   pageOptions.AutoCleanUp = True 
   pageOptions.UpdateImage = True 
 
   engine.AddFormPage(filledAttribute, filledFormImage, pageOptions) 
   engine.CloseForm(filledAttribute) 
 
   filledAttribute.Image = filledFormImage 
 
   Return engine.CompareFormFast(mastersAttributes, filledAttribute, Nothing)
