See Also  Example
Leadtools.ImageProcessing.Core Namespace > CorrelationCommand Class : NumberOfPoints Property



This property is updated with the number of areas in the image actually found to be correlated to the correlation image.

Syntax

Visual Basic (Declaration) 
Public ReadOnly Property NumberOfPoints As Integer
Visual Basic (Usage)Copy Code
Dim instance As CorrelationCommand
Dim value As Integer
 
value = instance.NumberOfPoints
C# 
public int NumberOfPoints {get;}
C++/CLI 
public:
property int NumberOfPoints {
   int get();
}

Return 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.

Example

Run the CorrelationCommand on an image.
