ColorMergeCommand Class

Summary

Creates a color image by merging grayscale images that were created as color separations. You can use this to recombine the images that the ColorSeparateCommand class creates.

Syntax

Java

Objective-C

WinRT C#

C++

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

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

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

@interface LTColorMergeCommand : LTRasterCommand

public class ColorMergeCommand extends RasterCommand

function Leadtools.ImageProcessing.Color.ColorMergeCommand()

public ref class ColorMergeCommand : public Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand, Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

Remarks

The supported color-space models are ColorMergeCommandType.Rgb, ColorMergeCommandType.Cmyk, ColorMergeCommandType.Cmy, ColorMergeCommandType.Hsv, ColorMergeCommandType.Hls, ColorMergeCommandType.Xyz, ColorMergeCommandType.Ycrcb, ColorMergeCommandType.Yuv, ColorMergeCommandType.Lab, and ColorMergeCommandType.Sct.
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 signed data images.
This command does not support 32-bit grayscale images.
