RasterHsvColor Structure

Summary

Describes a color consisting of relative intensities of hue, saturation, value.

Syntax
C#
VB
Java
Objective-C
C++
[SerializableAttribute()] 
public struct RasterHsvColor 
<SerializableAttribute()> 
Public Structure RasterHsvColor  
   Inherits System.ValueType 
@interface LTRasterHsvColor : NSObject<NSCopying> 
public final class RasterHsvColor 
[SerializableAttribute()] 
public value class RasterHsvColor : public System.ValueType  

Remarks

For more information on how to use this structure, refer to the AddColorHsvRangeToRegion method.

This structure does not support signed images.

Example

This example converts between HSV and RGB colors and back.
