问题描述
我在这里的问题类似于这里的问题,除了我使用的是 C#.
My question here is similar to the question here, except that I am working with C#.
我有两种颜色,我有一个预定义的步骤.如何检索作为两者之间渐变的 Color
列表?
I have two colors, and I have a predefine steps. How to retrieve a list of Color
s that are the gradients between the two?
这是我尝试过的一种方法,但没有奏效:
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));
}
如果你尝试上面的代码,你会发现argb
的逐渐增加并不对应于颜色的视觉逐渐增加.
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.
对此有什么想法吗?
推荐答案
您必须提取 R、G、B 分量并对它们中的每一个单独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);
var gAverage = gMin + (int)((gMax - gMin) * i / size);
var bAverage = bMin + (int)((bMax - bMin) * i / size);
colorList.Add(Color.FromArgb(rAverage, gAverage, bAverage));
}
