'Usage
 
Dim instance As FeretsDiameterCommand

public sealed class FeretsDiameterCommand

function Leadtools.ImageProcessing.Effects.FeretsDiameterCommand()

public ref class FeretsDiameterCommand

This command calculates the Feret's Diameter (caliper length), the longest distance between any two points along the boundary. This is equivalent to the minimum diameter of a tube through which this object can pass.
This command does not support signed data images.
