System Dependencies

• libpuzzle
• libgd

Installation

$ npm install puzzle

then...

var puzzle = require('puzzle');
var context = puzzle.context();	// create a context
var distance = context.compare('./test/img/1.jpg', './test/img/2.jpg');	// compare two images

distance will be 0 if the images are equal, the larger the number, the more "different" the images are. Generally, a number below .6 means they are considered similar. See the official libpuzzle docs for details.

Build and Test

node-gyp clean configure build && node test/test.js
