求js颜色转换算法

Posted 2023-03-24

求灰度转换16进制或者转换成rgb的算法，多谢
因为用于illustrator，所以不能使用jquery等，只能用纯js

参考技术A (function(d)function h(a,b,e)var c="rgb"+(d.support.rgba?"a":"")+"("+parseInt(a[0]+e*(b[0]-a[0]),10)+","+parseInt(a[1]+e*(b[1]-a[1]),10)+","+parseInt(a[2]+e*(b[2]-a[2]),10);d.support.rgba&&(c+=","+(a&&b?parseFloat(a[3]+e*(b[3]-a[3])):1));return c+")"function f(a)var b;return(b=/#([0-9a-fA-F]2)([0-9a-fA-F]2)([0-9a-fA-F]2)/.exec(a))?[parseInt(b[1],16),parseInt(b[2],16),parseInt(b[3],16),1]:(b=/#([0-9a-fA-F])([0-9a-fA-F])([0-9a-fA-F])/.exec(a))?[17*parseInt(b[1],16),17*parseInt(b[2],
16),17*parseInt(b[3],16),1]:(b=/rgb\(\s*([0-9]1,3)\s*,\s*([0-9]1,3)\s*,\s*([0-9]1,3)\s*\)/.exec(a))?[parseInt(b[1]),parseInt(b[2]),parseInt(b[3]),1]:(b=/rgba\(\s*([0-9]1,3)\s*,\s*([0-9]1,3)\s*,\s*([0-9]1,3)\s*,\s*([0-9\.]*)\s*\)/.exec(a))?[parseInt(b[1],10),parseInt(b[2],10),parseInt(b[3],10),parseFloat(b[4])]:l[a]d.extend(!0,d,support:rgba:function()var a=d("script:first"),b=a.css("color"),e=!1;if(/^rgba/.test(b))e=!0;else trye=b!=a.css("color","rgba(0, 0, 0, 0.5)").css("color"),
a.css("color",b)catch(c)return e());var k="color backgroundColor borderBottomColor borderLeftColor borderRightColor borderTopColor outlineColor".split(" ");d.each(k,function(a,b)d.Tween.propHooks[b]=get:function(a)return d(a.elem).css(b),set:function(a)var c=a.elem.style,g=f(d(a.elem).css(b)),m=f(a.end);a.run=function(a)c[b]=h(g,m,a));d.Tween.propHooks.borderColor=set:function(a)var b=a.elem.style,e=[],c=k.slice(2,6);d.each(c,function(b,c)e[c]=f(d(a.elem).css(c)));var g=f(a.end);

#fff rgb(10,10,10) hsl(100,40%,50%) 对应的？？追问

不是hsl
gray=0时 是白色
