AdjustTintCommand Class

Summary

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

Syntax

Objective-C

C++

Java

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:

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.
