生成颜色渐变的C＃ [英] Generate Color Gradient in C#

问题描述

在这里我的问题是类似这里问题，但我使用C＃的工作。

My question here is similar to the question here, except that I am working with C#.

我有两个颜色，我有一个predefine步骤。如何检索颜色 s表示两者之间的渐变列表？

I have two colors, and I have a predefine steps. How to retrieve a list of Colors that are the gradients between the two?

这是我试过了，没有工作的方法：

This is an approach that I tried, which didn't work:

int argbMax = Color.Chocolate.ToArgb();
int argbMin = Color.Blue.ToArgb();
var colorList = new List<Color>();

for(int i=0; i<size; i++)
{
    var colorAverage= argbMin + (int)((argbMax - argbMin) *i/size);
    colorList.Add(Color.FromArgb(colorAverage));
}

如果您尝试了上面code，你会发现，在的argb 逐渐增加不对应的颜色视觉逐渐增加。

If you try the above code, you will find that a gradual increase in argb doesn't correspond to a visual gradual increase in the color.

在这个任何想法？

推荐答案

您必须提取R，G，B分量并分别对他们每个人执行相同的线性插值，然后重新组合。

You will have to extract the R, G, B components and perform the same linear interpolation on each of them individually, then recombine.

int rMax = Color.Chocolate.R;
int rMin = Color.Blue.R;
// ... and for B, G
var colorList = new List<Color>();
for(int i=0; i<size; i++)
{
    var rAverage = rMin + (int)((rMax - rMin) * i / size);
    // ... and for B, G
    colorList.Add(Color.FromArgb(rAverage, gAverage, bAverage));
}
