'Declaration
 
Public Property Threshold As Integer

'Usage
 
Dim instance As OmrProcessor
Dim value As Integer
 
instance.Threshold = value
 
value = instance.Threshold

public int Threshold {get; set;}

public: __property int get_Threshold();
public: __property void set_Threshold( 
   int value
);

public:
property int Threshold {
   int get();
   void set (    int value);
}

This property specifies a threshold between 0 and 99 at which the bubble will be considered to be marked if the mark density of the bubble exceeds the threshold.

This property is used only when the RecognitionEngine property has a value of RecognitionEngine.SingleThreshold.

The value used for this property will depend on whether the field is an OMR bubble (which will be filled in completely) or a signature or checkbox (which will only be partially marked). The default value is appropriate for OMR bubbles. For signature or checkbox fields, use a lower value such as 10 or 5.

Default value: 25
