RasterHsvColor Structure

Summary

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

Syntax

Objective-C

C++/CLI

Java

Python

[SerializableAttribute()] 
public struct RasterHsvColor

@interface LTRasterHsvColor : NSObject<NSCopying>

public final class RasterHsvColor

[SerializableAttribute()] 
public value class RasterHsvColor : public System.ValueType

class RasterHsvColor:

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.

Java

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);

   Console.WriteLine("rgb2 = {0}, {1}, {2}", rgb2.R, rgb2.G, rgb2.B);
