NumberOfPoints Property (CorrelationCommand)

Example 





This property is updated with the number of areas in the image actually found to be correlated to the correlation image. .NET support WinRT support Silverlight support
Syntax
public int NumberOfPoints {get;}
'Declaration
 
Public ReadOnly Property NumberOfPoints As Integer
'Usage
 
Dim instance As CorrelationCommand
Dim value As Integer
 
value = instance.NumberOfPoints
public int NumberOfPoints {get;}
 get_NumberOfPoints(); 
public:
property int NumberOfPoints {
   int get();
}

Property Value

Value that indicates the number of areas in the image actually found to be correlated to the correlation image. Its maximum value is the length of the Points array.
