Documentation

Color Thief

Build Status

A script for grabbing the color palette from an image. This is a fork of the original color-thief library, modified to work in node as well as in the browser.

Further changes have been made to code structure as well as tests and general organisation.

A demo may be found on the original projects site: lokeshdhakar.com

How to use

In node simply require:

var ColorThief = require('@paulavery/color-thief')

In a browser simply reference the main file, which will provide window.ColorThief.

<!-- installed via bower -->
<script src="bower_components/color-thief/lib/browser.min.js"></script>

<!-- installed via npm -->
<script src="node_modules/color-thief/lib/browser.min.js"></script>

Get the dominant color from an image

var colorThief = new ColorThief();
colorThief.getColor(sourceImage);
getColor(sourceImage[, quality])
returns {r: num, g: num, b: num}

Build a color palette from an image

In this example, we build an 8 color palette.

var colorThief = new ColorThief();
colorThief.getPalette(sourceImage, 8);
getPalette(sourceImage[, colorCount, quality])
returns [ [num, num, num], [num, num, num], ... ]

Tests

To run the tests, simply call make test. Tests may be found in the test directory and utilize mocha as well as phantomjs for testing in the browser as well as node.
