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

'Declaration
 
Public Class MaximumCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As MaximumCommand

public sealed class MaximumCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.Core.MaximumCommand()

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

This command can process the whole image or a region of the image.
The effect can be controlled by specifying the size of the neighborhood that is used for calculating each pixel value. For example, for 8x8, set Dimension property (or the dimension parameter of the Constructor) to 8. Each pixel is replaced with the maximum value of its neighborhood.
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.
