试图将rgb从.net颜色转换为字符串，如“红色”或“蓝色” [英] trying to convert rgb from a .net Color to a string such as "red" or "blue"

问题描述

我的所有方法都以各种方式使我失望。

有任何人都试图返回一个名称给一个rgb值？ 红色，绿色，蓝色将足以满足我今天的需要。

我有来自我的网络摄像头的图像的不安全的字节处理。

解决方案

如果你有一个已知的颜色名称列表，你可以看到那些已知的颜色，使用沿（F＃代码）行的'closeeness'函数：

 让Diff（c1：Color） ：Color）= 
 let dr =（c1.R-c2.R）|> int 
 let dg =（c1.G-c2.G）|> int 
 let db =（c1.B-c2.B）|> int 
 dr * dr + dg * dg + db * db 
  

颜色与要命名的目标颜色的差异最小，请使用该名称。

All of my methods are failing me in various ways. different lighting can mess it all up too.

has anyone every trying to return a name given a rgb value? "red" "green" "blue" would be enough to satisfy my needs for today.

i have unsafe byte processing of images from my web cam.

解决方案

If you have a list of known colors with names, you can see which of those known colors a given target color is 'closest' to, using a 'closeness' function along the lines of (F# code):

let Diff (c1:Color) (c2:Color) =
    let dr = (c1.R - c2.R) |> int
    let dg = (c1.G - c2.G) |> int
    let db = (c1.B - c2.B) |> int
    dr*dr + dg*dg + db*db

Whichever one of the known colors has the smallest diff to the target color you want to name, use that name.
