Blockies

A tiny library for generating blocky identicons.

Demo page

Use

var icon = blockies.create({ // All options are optional
    seed: 'randstring', // seed used to generate icon data, default: random
    color: '#dfe', // to manually specify the icon color, default: random
    bgcolor: '#aaa', // choose a different background color, default: random
    size: 15, // width/height of the icon in blocks, default: 8
    scale: 3, // width/height of each block in pixels, default: 4
    spotcolor: '#000' // each pixel has a 13% chance of being of a third color, 
    // default: random. Set to -1 to disable it. These "spots" create structures
    // that look like eyes, mouths and noses. 
});

document.body.appendChild(icon); // icon is a canvas element

In the above example the icon will be 15x15 blocks, and each block will be 3x3 pixels. The icon canvas will be 45x45 pixels.

Notes

The defaults of size 8 and scale 4 generate 32x32 pixel icons. Below are some standard sizes that work well. A size larger than 10 will start generating more noisy icons that don't ressemble much.

• 24x24 {size: 8, scale: 3}
• 50x50 {size: 5, scale: 10}

Build

node build

All this does is minify blockies.js to blockies.min.js.
