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

Public Class ChannelMixerCommand  
   Inherits Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand 
   Implements Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

public sealed class ChannelMixerCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

@interface LTChannelMixerCommand : LTRasterCommand

public class ChannelMixerCommand extends RasterCommand

function Leadtools.ImageProcessing.Color.ChannelMixerCommand()

public ref class ChannelMixerCommand : public Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand, Leadtools.Imageprocessing.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-bit, 2-bit, 3-bit, 4-bit, 5-bit, 6-bit, 7-bit, 8-bit, 24-bit, 48-bit and 64-bit images and can support regions for 24-bit, 48-bit 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.
