Identicon

PHP aplication that generates identicons. It is built with Silex and Imagine, and is inspired by Github's Identicons project.

What is an identicon? (from wikipedia)

It is a visual representation of a hash value [...] that serves to identify a user of a computer system as a form of avatar while protecting the users' privacy.

How to use

If you want to get username's avatar, you only have to use the next URL:

http://your-identicon-server/username.png

The response of the app will be the next image:

You can check the online demo.

Installation

Get the source code of the project from GitHub. You have two options:

A. Clone it:

git clone git@github.com:rmhdev/identicon.git /MY/FOLDER
cd /MY/FOLDER
git checkout v2.0.0

B. Download it:

Check the latest release and copy it to your installation folder.

Project dependencies

Retrieve all the dependencies using Composer. Install it and then run the next command:

php ./composer.phar install --no-dev

Server configuration

This project is built using Silex. The official docs will give you more information about how to configure your server. Some tips:

• the document root must point to the identicon/web/ directory.
• folders in identicon/var/ must be writable by the web server.

Play with Identicon

If you are using PHP 5.4+, its built-in web server will help you to play with this project:

cd identicon/
php -S localhost:8080 -t web web/index.php

Easy, right? Just open a browser and enter http://localhost:8080

Customize the identicon generator

In the config folder, copy the file parameters.dist.json and paste it with the name parameters.json. The default values are:

{
    "identicon.config": {
        "blocks": 5,
        "block-size": 70,
        "margin": 35,
        "background-color": "f0f0f0"
    },
    "identicon.type": {
        "default": "plain",
        "extra": ["circle", "pyramid", "rhombus"]
    }
}

Default Identicon types

Plain, pyramid, circle and rhombus

Create your own Identicons

Take a look at src/Identicon/Type/. If you want to create a new Identicon type, extend the AbstractIdenticon class. For example:

<?php

namespace Identicon\Type\MyType;

use Identicon\AbstractIdenticon;
use Imagine\Image\Point;

class Identicon extends AbstractIdenticon implements IdenticonInterface
{
    protected function drawBlock($x, $y)
    {
        //parent::drawBlock($x, $y);
        $this->getImage()->draw()->dot(
            $this->getCell($x, $y)->getCenter(),
            $this->getColor()
        );
    }
}

Unit tests

Check the Travis page to see the build status. If you want to run the tests by yourself, run the next command:

php ./vendor/bin/phpunit

If you don't have phpunit installed, run:

php ./composer.phar install
