AdjustTintCommand Class

Summary

Adjusts the image tint by changing the colors in an image by using two separate color wheel rotations.

Syntax
C#
VB
Java
Objective-C
C++
public class AdjustTintCommand : RasterCommand 
Public Class AdjustTintCommand  
   Inherits RasterCommand 
@interface LTAdjustTintCommand : LTRasterCommand 
public class AdjustTintCommand extends RasterCommand 
public ref class AdjustTintCommand : public RasterCommand   

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: adjusttint.jpg 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 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.

Example

Run the AdjustTintCommand on an image and apply the Adjust Tint filter.
