DesaturateCommand Class
See Also  Members   Example 




Converts the image to a grayscale level by reducing the saturation of each color to zero. The conversion will not change the color resolution.

Syntax

Visual Basic (Declaration) 
Public Class DesaturateCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage)Copy Code
Dim instance As DesaturateCommand
C# 
public class DesaturateCommand : RasterCommand, IRasterCommand 
Managed Extensions for C++

Example

Visual BasicCopy Code
ImageProcessing.Color.DesaturateCommand
   Public Sub DesaturateCommandExample()
      RasterCodecs.Startup()
      Dim codecs As New RasterCodecs()
      codecs.ThrowExceptionsOnInvalidImages = True

      Dim leadImage As RasterImage = codecs.Load("C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Master.jpg")

      ' Prepare the command
      ' Apply deSaturate effect on the image.
      Dim command As DesaturateCommand = New DesaturateCommand
      command.Run(leadImage)
      codecs.Save(leadImage, "C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Result.jpg", RasterImageFormat.Jpeg, 24)

  • The image is converted to a grayscale level by reducing the saturation of each color to zero.
  • This class supports only RGB images. It does not support grayscale images.
  • Support for 48-bit and 64-bit colored images are available only in the Document/Medical toolkits.
  • This class does not support signed data images.
  • This command does not support 32-bit grayscale images.
