Adjusts the image tint by changing the colors in an image by using two separate color wheel rotations. Supported in Silverlight, Windows Phone 7

Object Model

AdjustTintCommand Class

Syntax

Visual Basic (Declaration) 
Public Class AdjustTintCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage)Copy Code
Dim instance As AdjustTintCommand
C# 
public class AdjustTintCommand : Leadtools.ImageProcessing.RasterCommand, IRasterCommand

Remarks

  • This command changes the colors in an image by using two separate color wheel rotations. For the AdjustTintCommand.AngleA parameter, a positive rotation takes blue toward green and red, as shown in the following figure:

    Negative rotation has the opposite effect. For the AdjustTintCommand.AngleB parameter, a positive rotation takes red toward green. Negative rotation has the opposite effect.
  • This command supports only colored images.
  • This command supports 48 and 64-bit color images. Support for 48 and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support signed data images.
  • Use the Leadtools.ImageProcessing.Color.ChangeHueCommand to rotate the color wheel in either direction using one angle change that changes each color in the image. A 180-degree rotation in either direction changes each color to its complement. Positive rotation takes red toward green, green toward blue, and blue toward red. Negative rotation has the opposite effect.
  • This command does not support 32-bit grayscale images.
