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

'Declaration

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

'Usage

Dim instance As ColorSeparateCommand

public sealed class ColorSeparateCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTColorSeparateCommand : LTRasterCommand

public class ColorSeparateCommand extends RasterCommand

function Leadtools.ImageProcessing.Color.ColorSeparateCommand()

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

The supported color-space models are Rgb, Cmyk, Cmy, Hsv, Hls, Xyz, Ycrcb, Yuv, Lab and Sct.
The pointers in the array should be in the appropriate order, which in most cases is the order of the letters in the name. For example, for CMY separation, the first pointer should be for the cyan plane, the second for magenta, and the third for yellow. The only exception is RGB, which should be in BGR (blue, green, red) order.
This class 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 class does not support signed data images.
This command does not support 32-bit grayscale images.

Run the ColorSeparateCommand on an image and separate the color planes.
