ChannelMixerCommand Class

Summary

Redistributes the RGB values of a specific image, using the values in the ChannelMixerCommandFactor classes.

Syntax

Objective-C

C++

Java

public class ChannelMixerCommand : RasterCommand

Public Class ChannelMixerCommand  
   Inherits RasterCommand

@interface LTChannelMixerCommand : LTRasterCommand

public class ChannelMixerCommand extends RasterCommand

public ref class ChannelMixerCommand : public RasterCommand

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.

Example

Run the ChannelMixerCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
public void ChannelMixerCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\Image1.jpg")); 
 
   // Prepare the command 
   ChannelMixerCommandFactor RedFactor = new ChannelMixerCommandFactor(); 
   RedFactor.Red = 50; 
   RedFactor.Green = 0; 
   RedFactor.Blue = 0; 
   RedFactor.Constant = 0; 
   ChannelMixerCommandFactor GreenFactor = new ChannelMixerCommandFactor(); 
   GreenFactor.Red = 100; 
   GreenFactor.Green = 100; 
   GreenFactor.Blue = 0; 
   GreenFactor.Constant = 0; 
   ChannelMixerCommandFactor BlueFactor = new ChannelMixerCommandFactor(); 
   BlueFactor.Red = 0; 
   BlueFactor.Green = 0; 
   BlueFactor.Blue = 100; 
   BlueFactor.Constant = 0; 
   ChannelMixerCommand command = new ChannelMixerCommand(RedFactor, GreenFactor, BlueFactor); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
