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

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

'Usage
 
Dim instance As ChannelMixerCommand

public sealed class ChannelMixerCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.Color.ChannelMixerCommand()

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

Remarks

This command is used to rebalance the colors in an image. It can be used to make color adjustments and corrections.
This command supports 1-, 2-, 3-, 4-, 5-, 6-, 7-, 8-, 24-, 48- and 64-bit images and can support regions for 24-, 48- and 64-bit images. If the image has a region, the effect will be applied on the region only.
This command does not support signed data images.
This command does not support 32-bit grayscale images.
