想了解C#实现HSL颜色值转换为RGB的方法的相关内容吗,小卒过河在本文为您仔细讲解C#实现HSL颜色值转换为RGB的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:C#,HSL,颜色值,转换,RGB,下面大家一起来学习吧。

本文实例讲述了C#实现HSL颜色值转换为RGB的方法。分享给大家供大家参考。具体实现方法如下:

//This method converts the values to RGB
public RgbColor HslToRgb(int Hue, int Saturation, int Lightness)
{
 double num4 = 0.0;
 double num5 = 0.0;
 double num6 = 0.0;
 double num = ((double)Hue) % 360.0;
 double num2 = ((double)Saturation) / 100.0;
 double num3 = ((double)Lightness) / 100.0;
 if (num2 == 0.0)
 {
  num4 = num3;
  num5 = num3;
  num6 = num3;
 }
 else
 {
  double d = num / 60.0;
  int num11 = (int)Math.Floor(d);
  double num10 = d - num11;
  double num7 = num3 * (1.0 - num2);
  double num8 = num3 * (1.0 - (num2 * num10));
  double num9 = num3 * (1.0 - (num2 * (1.0 - num10)));
  switch (num11)
  {
   case 0:
    num4 = num3;
    num5 = num9;
    num6 = num7;
    break;
   case 1:
    num4 = num8;
    num5 = num3;
    num6 = num7;
    break;
   case 2:
    num4 = num7;
    num5 = num3;
    num6 = num9;
    break;
   case 3:
    num4 = num7;
    num5 = num8;
    num6 = num3;
    break;
   case 4:
    num4 = num9;
    num5 = num7;
    num6 = num3;
    break;
   case 5:
    num4 = num3;
    num5 = num7;
    num6 = num8;
    break;
  }
 }
 return new RgbColor((int)(num4 * 255.0), (int)(num5 * 255.0), (int)(num6 * 255.0));
}
//The structure that will hold the RGB Values
public struct RgbColor
{
 public RgbColor(int r, int g, int b)
 {
  red = r;
  green = g;
  blue = b;
 }
 public int red;
 public int green;
 public int blue;
}
