Install

npm install xyz-utils

..then require xyz-utils:

var xyzUtils = require('xyz-utils');

Basic Usage

var xyzUtils = require('xyz-utils');

var rgbColor = [1.2, 22.5, 1.9];

var xyzColor = xyzUtils.fromRGB(rgbColor);

xyzUtils.toRGB(xyzColor); //=> [1.2, 22.5, 1.9]

API

All functions are of the format: outputArray = function (inputColorArray[, outputArray]). All "from*" functions return XYZ and all "to*" functions expect XYZ.

Current functions are:

• toRGB
• fromRGB
• toxyY
• fromxyY
• toLuv
• fromLuv

Versions

• v0.5.2 Added Luv support
• v0.5.1 Allows an optional second argument for an array to fill to avoid allocating tons of little arrays in hot loops
• v0.5.0 Initial public release
