See Also  Members   Example 



Separates an image by color plane to produce one grayscale image per plane. You can specify any of several color-space models, including CMYK.

Syntax

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

Example

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

Visual BasicCopy Code
Public Sub ColorSeperateCommandExample()
   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 command As ColorSeparateCommand = New ColorSeparateCommand
   command.Type = ColorSeparateCommandType.Rgb

   command.Run(leadImage)
   Dim i As Integer
   For i = 3 To 1 Step -1
      command.DestinationImage.Page = i
      leadImage.AddPage(command.DestinationImage)
   Next

   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)
   RasterCodecs.Shutdown()
End Sub
