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++/CLI

Java

Python

public bool EnableQuickPreRecognitionCheck { get; set; }

public boolean isEnabledQuickPreRecognitionCheck(); 
isEnabledQuickPreRecognitionCheck();

public:  
   property bool EnableQuickPreRecognitionCheck 
   { 
      bool get() 
      void set(bool value) 
   }

EnableQuickPreRecognitionCheck # get and set (AutoFormsEngine)

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.
