Perfect Layout

Medium Article

DEMO

given an array of images in the form

{   data: WATHEVER_YOU_WANT,   src: "path/to/image.jpg",   ratio: 1.5 } 

returns an array of images in the form

{   data: WATHEVER_YOU_WANT,   src: "path/to/image.jpg",   width: WIDTH,   height: HEIGHT } 

where WIDTH and HEIGHT are the dimensions that image must have to fit the layout.

Usage

on node

$ npm install --save perfect-layout 

and

var perfectLayout = require('perfect-layout') 

while on the browser you can just

<script src="perfectLayout.min.js"></script> 

then

var perfectRows = perfectLayout(photos, width, height, {   // default options   margin: 0 }); 

Options

  • margin: [number] If you are going to use a css margin for your images you need to specify it here as well, so that the layout will adapt to scale down the images accordingly.

Motivations

This was inspired by chromatic.io galleries and I want to credit the @crispymtn team for the original implementation.

This version aim to be more lightweight using a greedy algorithm instead of the optimal one and also leave to the user the responsability to choose how to manipulate the DOM accordingly to the returned array.

Example jQuery plugin

for convenience a jquery plugin is included for a basic usage.

assuming that a global window.photos array exists as specified above

<div id="gallery"></div>  <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.4/jquery.js"></script> <script src="jquery.perfectLayout.min.js"></script>  <script> $(document).ready(function() {   $('#gallery').perfectGallery(photos);    $(window).resize(function() {     $('#gallery').perfectGallery(photos);   }); });  </script> 

N.B. Please note that this is only an example on how to use the perfectLayout function. The jQuery plugin is not to be used in production as it do not provide any crossbrowser optimization, at the time of writing it should however correctly work on the latest chrome and firefox browsers on linux.

For custom behaviour give a look at the jqueryPlugin.js and use it as a starting point to generate the desired DOM nodes.

the data field can be used to populate the images with any needed metadata you may need and is probably a good idea to provide it from your backend.
