    XYZ-UTILS

    A simple set of functions to convert between XYZ and other color spaces (currently, supports RGB, xyY, and Luv). All pixels are floating point to support high dynamic range imaging.

    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
