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rgb
export 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)"}
}
