public class ChangeHueSaturationIntensityCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration
 
Public Class ChangeHueSaturationIntensityCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As ChangeHueSaturationIntensityCommand

public sealed class ChangeHueSaturationIntensityCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.Color.ChangeHueSaturationIntensityCommand()

public ref class ChangeHueSaturationIntensityCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

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.
