image-layout

NPM version

A collection of deterministic image layout algorithms written in pure javascript that work just as well on a server as in a browser. None of them are tied to the DOM in any way.

$ npm install image-layout --save

Sample Usage

var layout = require('image-layout/layouts/fixed-partition');
var elements = [
	{width: 400, height: 300},
	{width: 200, height: 100}
];

var result = layout(elements);
// container_width = result.width
// container_height = result.height
for (var i = 0, n = elements.length; i < n; i++) {
	// result.positions[i].x
	// result.positions[i].y
	// result.positions[i].width
	// result.positions[i].height
}

Layouts

fixed-columns

Simply balances photos into multiple columns.

var layout = require('image-layout/layouts/fixed-columns');
var result = layout(elements, {
    containerWidth: 800,
    columnCount: 3,
    spacing: 0
});

fixed-partition

Uses a partitioning scheme outlined by Johannes Treitz in "The algorithm for a perfectly balanced photo gallery". It's not the most-efficient option, but it leaves no ragged edges.

var layout = require('image-layout/layouts/fixed-partition');
var result = layout(elements, {
    align: 'center', // optional
    containerWidth: 800,
    idealElementHeight: 300,
    spacing: 0
});

single

Constrains a single image to a given area.

var layout = require('image-layout/layouts/single');
var result = layout(elements, {
    align: 'center', // optional
    containerWidth: 800,
    maxHeight: 800
});
