C#实现颜色空间转换

实验一颜色空间转换

下载链接：/share/link?shareid=139708&uk=521254270 一、实验目的

理解颜色空间的原理,并实现各颜色空间的转换算法.

二、实验内容和步骤

请编程实现以下转换算法:

1.RGB ←→CMY

2.RGB ←→ HSL

3.RGB ←→ HSV

三、实验要求

1. 实现语言不做要求, C, C++, Java, Matlab均可

2. 要求按照课本上的算法实现

3. 请关键语句都加上注释

四、实验结果（本次实验采用C#语言）

1．实验界面截图：

（1）初始截图

（2）操作后截图

2.实验代码
