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

Objective-C

C++/CLI

Java

Python

public class ColorMergeCommand : RasterCommand

@interface LTColorMergeCommand : LTRasterCommand

public class ColorMergeCommand 
    extends RasterCommand

public ref class ColorMergeCommand : public RasterCommand

class ColorMergeCommand(RasterCommand):

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.

Example

Run the ColorMergeCommand on an image.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void ColorMergeCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   ColorSeparateCommand colorseparatecommand = new ColorSeparateCommand(); 
   colorseparatecommand.Type = ColorSeparateCommandType.Rgb;

   // Prepare the command 
   ColorMergeCommand command = new ColorMergeCommand(ColorMergeCommandType.Rgb); 
   command.Run(colorseparatecommand.DestinationImage);
