EnableQuickPreRecognitionCheck Property

Summary

Indicates whether to use the quick-check process to identify the form. If it fails, it will perform the recognition process.

Syntax
C#
VB
C++
Java
public bool EnableQuickPreRecognitionCheck { get; set; } 
public boolean isEnabledQuickPreRecognitionCheck(); 
isEnabledQuickPreRecognitionCheck(); 
Public Property EnableQuickPreRecognitionCheck() As Boolean 
   Get 
   Set 
public:  
   property bool EnableQuickPreRecognitionCheck 
   { 
      bool get() 
      void set(bool value) 
   } 

Property Value

true to use the quick-check process to identify the form.

Remarks

The quick-check process tries to identify the form before performing the recognition process. This is useful to speed up the recognition process when the scanned forms have the same resolution as the master form.
