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;}

@property (nonatomic, assign, readonly) NSUInteger numberOfPoints

public int getNumberOfPoints()

 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.

Run the CorrelationCommand on an image.
