ChangeHueSaturationIntensityCommand Class

Summary

Changes the hue, saturation and brightness of all colors or specific colors in the image.

Syntax

Objective-C

C++

Java

public class ChangeHueSaturationIntensityCommand : RasterCommand

Public Class ChangeHueSaturationIntensityCommand  
   Inherits RasterCommand

@interface LTChangeHueSaturationIntensityCommand : LTRasterCommand

public class ChangeHueSaturationIntensityCommand extends RasterCommand

public ref class ChangeHueSaturationIntensityCommand : public RasterCommand

Remarks

This command combines the basic functionality found in the ChangeHueCommand, ChangeSaturationCommand, and ChangeIntensityCommand commands. In addition, special options can be specified in the ChangeHueSaturationIntensityCommandData class.
To change the overall hue, saturation and intensity all at one time, set the Data property to null. To adjust the parameters separately, or to make adjustments in successive passes, use the ChangeHueSaturationIntensityCommandData classes and pass 0 for the Hue, Saturation, and Intensity properties in the this class.
For detailed information about using the ranges refer to ChangeHueSaturationIntensityCommandData class.
This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This command does not support signed data images.
This command does not support 32-bit grayscale images.

For more information, refer to Changing Brightness and Contrast. For more information, refer to Correcting Colors.

Example

Run the ChangeHueSaturationIntensityCommand on an image to change its hue, saturation, and brightness and change the red color to green.
