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

'Declaration

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

'Usage

Dim instance As MinimumCommand

public sealed class MinimumCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTMinimumCommand : LTRasterCommand

public class MinimumCommand extends RasterCommand

function Leadtools.ImageProcessing.Core.MinimumCommand()

public ref class MinimumCommand : 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 the Dimension property to 8 or pass 8 for the dimension parameter of the Constructor. Each pixel is replaced with the minimum 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.
This command supports signed/unsigned data images.

For more information, refer to Removing Noise.

Run the MinimumCommand on an image with a neighborhood Dimensions = 3x3 pixels.
