Summary

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

Syntax

Objective-C

C++/CLI

Java

Python

[SerializableAttribute()]

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.

using Leadtools; 
 
 
public void RasterHsvColorExample() 
{ 
	const int R = 50; 
	const int G = 100; 
	const int B = 200; 
	// Expected HSV values based on RGB(50,100,200) 
	const int H = 149; 
	const int S = 191; 
	const int V = 200; 
 
	RasterColor rgb1 = new RasterColor(R, G, B); 
	Assert.IsTrue(rgb1.R == R && rgb1.G == G && rgb1.B == B); 
	Console.WriteLine("rgb1 = {0}, {1}, {2}", rgb1.R, rgb1.G, rgb1.B); 
 
	RasterHsvColor hsv1 = RasterHsvColor.FromRasterColor(rgb1); 
	Assert.IsTrue(hsv1.H == H && hsv1.S == S && hsv1.V == V); 
	Console.WriteLine("hsv1 = {0}, {1}, {2}", hsv1.H, hsv1.S, hsv1.V); 
 
	RasterHsvColor hsv2 = new RasterHsvColor(hsv1.H, hsv1.S, hsv1.V); 
	Assert.IsTrue(hsv2.H == H && hsv2.S == S && hsv2.V == V); 
	Console.WriteLine("hsv2 = {0}, {1}, {2}", hsv2.H, hsv2.S, hsv2.V); 
 
	RasterColor rgb2 = hsv2.ToRasterColor(); 
	Assert.IsTrue(rgb2.R == R && rgb2.G == G && rgb2.B == B); //rgb2.G = 102 ?? 
	Console.WriteLine("rgb2 = {0}, {1}, {2}", rgb2.R, rgb2.G, rgb2.B); 
}
