ColorMergeCommand Class
See Also  Members   Example 



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

Visual Basic (Declaration) 
Public Class ColorMergeCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage)Copy Code
Dim instance As ColorMergeCommand
C# 
public class ColorMergeCommand : RasterCommand, IRasterCommand 
C++/CLI 
public ref class ColorMergeCommand : public RasterCommand, IRasterCommand 

Example

Run the ColorMergeCommand on an image.

Visual BasicCopy Code
Public Sub ColorMergeCommandExample()
   RasterCodecs.Startup()
   Dim codecs As New RasterCodecs()
   codecs.ThrowExceptionsOnInvalidImages = True

   Dim leadImage As RasterImage = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg")

   ' Prepare the command
   Dim colorseparatecommand As ColorSeparateCommand = New ColorSeparateCommand
   colorseparatecommand.Type = ColorSeparateCommandType.Rgb
   colorseparatecommand.Run(leadImage)

   ' Prepare the command
   Dim command As ColorMergeCommand = New ColorMergeCommand(ColorMergeCommandType.Rgb)
   command.Run(colorseparatecommand.DestinationImage)
   codecs.Save(command.DestinationImage, LeadtoolsExamples.Common.ImagesPath.Path + "ColorMergeCommandResult.Bmp", RasterImageFormat.Bmp, 24)

   RasterCodecs.Shutdown()
End Sub

   // Load an image 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg");

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