十六进制颜色值和rgb颜色值转换

// 将rgb颜色转成hex , 列如 输入(24,12,255)

export function colorRGB2Hex(r, g, b) {let hex = "#" + ((1 << 24) + (r << 16) + (g << 8) + b).toString(16).slice(1);return hex;}//返回结果：#180cff

// 将hex颜色转成rgb, 输入（“#3ba272”）

// 将hex颜色转成rgbexport function hexToRgba(hex, opacity) {//hex："#3ba272"； opacity：透明度let RGBA = "rgba(" + parseInt("0x" + hex.slice(1, 3)) + "," + parseInt("0x" + hex.slice(3, 5)) + "," + parseInt("0x" + hex.slice(5, 7)) + "," + opacity + ")";return {//返回值对象red: parseInt("0x" + hex.slice(1, 3)),green: parseInt("0x" + hex.slice(3, 5)),blue: parseInt("0x" + hex.slice(5, 7)),rgba: RGBA};//返回结果：{blue: 114， green: 162 ，red: 59 ，rgba: "rgba(59,162,114,1)"}}
