public class ContourFilterCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration

Public Class ContourFilterCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage

Dim instance As ContourFilterCommand

public sealed class ContourFilterCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.Effects.ContourFilterCommand()

public ref class ContourFilterCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

Remarks

The bits per pixel of the affected image will change according to the value of Type property, or the type parameter of the constructor as follows:

If the type is	Bits per pixel will be:
Thin	8 bits per pixel grayscale
LinkBlackWhite	1 bit per pixel
LinkGray	8 bits per pixel grayscale
LinkColor	8 bits per pixel color
ApproxColor	8 bits per pixel color

This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This command does not support 32-bit grayscale images.
