我正在寻找一种工具或算法来将HSL颜色转换为RGB.在我看来,HSL并没有被广泛使用,所以我没有太多运气寻找转换器.
给定一个RGB值,比如168, 0, 255,如何创建颜色(使其更亮)和阴影(使其更暗)的颜色？
有没有办法随机更改原生Leaflet中的标记颜色？我正在使用可以设计风格的svg元素.我知道mapbox.js是可行的
编辑:澄清我打算做什么:如果您通过双击或其他东西添加标记,它应该有随机颜色.为了实现这一点,我想使用标记的svg图标来设置它们的样式.
这是我的代码:
myIcon = L.icon({
iconUrl: "icon_33997.svg",
iconAnchor: pinAnchor
});
newMarker = L.marker(lat, long], {
icon: myIcon
});
我需要准确地将HSB转换为RGB,但我不知道如何解决将小数转换为整数而不进行舍入的问题.这是我在colorpicker库中使用的当前函数:
HSBToRGB = function (hsb) {
var rgb = { };
var h = Math.round(hsb.h);
var s = Math.round(hsb.s * 255 / 100);
var v = Math.round(hsb.b * 255 / 100);
if (s == 0) {
rgb.r = rgb.g = rgb.b = v;
} else {
var t1 = v;
var t2 = (255 - s) * v / 255;
var t3 = (t1 - t2) * (h % 60) / 60;
if (h == 360) h = 0;
if …我正在将Color类作为c ++中非常基本的图形API的一部分.所以我决定看一下微软的.NET框架,发现他们的Color类有HSB的功能.
然后我开始研究,以确定我是否应该在课堂上提供HSB,HSL或HSV或所有这些.
所以,我有3个关于HSB,HSL,HSV的问题:
HSB与HSL相同吗？
如果没有,为什么没有HSBL甚至HSBLV？
我发现有很多不同的计算这些值的方法,有人能告诉我最快的吗？
我在http://www.mjijackson.com/2008/02/rgb-to-hsl-and-rgb-to-hsv-color-model-conversion-algorithms-in-javascript上找到了这个RGB到HSL脚本.我找不到任何其他小的体面的.问题是这段代码甚至不起作用.有谁知道为什么？(我不知道一点颜色数学,但也许它正在返回补充？)
function rgbToHsl(r, g, b){
r /= 255, g /= 255, b /= 255;
var max = Math.max(r, g, b), min = Math.min(r, g, b);
var h, s, l = (max + min) / 2;
if(max == min){
h = s = 0; // achromatic
}else{
var d = max - min;
s = l > 0.5 ? d / (2 - max - min) : d / (max + min);
switch(max){
case r: h = (g - …我可以将HSB颜色转换为HSL吗？
Photoshop在其颜色选择器中显示HSB颜色.HSL颜色可以在CSS中使用.
我试过这个JS:
function hsb2hsl(h, s, b) {
return {
h: h,
s: s,
l: b-s/2
}
}
而hsb2hsl(0, 100, 50).l == 0不是25
更新:如果不转换HSB→RGB→HSL,我可以这样做吗？
我需要一个颜色转换器从hsl转换为rgb和十六进制值.我会像这样做.我正在使用jquery和jquery ui range slider.这是我的代码:
$(function() {
$( "#hsl_hue_range" ).slider({
min: 0,
max: 100,
value: 0,
range: false,
animate:"slow",
orientation: "horizontal",
slide: function( event, ui ) {
var hsl_hue = ui.value;
}
});
});
$(function() {
$( "#hsl_saturation_range" ).slider({
min: 0,
max: 100,
value: 0,
range: false,
animate:"slow",
orientation: "horizontal",
slide: function( event, ui ) {
var hsl_saturation = ui.value;
}
});
});
$(function() {
$( "#hsl_light_range" ).slider({
min: 0,
max: 100,
value: 0,
range: false,
animate:"slow",
orientation: "horizontal", …我希望尽可能精确地对齐以下颜色数组.
搜索并尝试在Stackoverflow上建议的许多解决方案后,pusher.color库具有最佳解决方案,但是,它也远非完美.我想听听我们如何完美地对齐它们的解决方案.
