gnikyt/backlight

A pointless PHP library for getting the mean and glow background colors of an image or icon.

Backlight

Backlight is a pointless script inspired by the Ubuntu Unity Launcher. It will take an image/icon, and find it's mean background color as well as it's glow color. It will return an object with values in both RGB and HEX format for use.

Fetch

The recommended way to install Backlight is through composer.

Just create a composer.json file for your project:

{
    "minimum-stability" : "dev",
    "require": {
        "tyler-king/backlight": "dev-master"
    }
}

And run these two commands to install it:

$ curl -s http://getcomposer.org/installer | php
$ php composer.phar install

Now you can add the autoloader, and you will have access to the library:

<?php
require 'vendor/autoload.php';

Usage

The usage is pretty stright forward, very chainable (see the source). This is a basic example below.

<?php

use TylerKing\Backlight\Backlight;

$backlight = new Backlight('chrome-icon.png');
print_r($backlight->getBackground()); // Returns the RGB and HEX of the background to use.
print_r($backlight->getMean()); // Returns the RGB and HEX of the outter glow to use.

By running print_r or var_dump you will receieve an output containing the mean background-color and the glow color for the icon or image.

stdClass Object
(
    [background] => stdClass Object
        (
            [rgb] => Array
                (
                    [0] => 192
                    [1] => 123
                    [2] => 18
                )

            [hex] => #c07b12
        )

    [glow] => stdClass Object
        (
            [rgb] => Array
                (
                    [0] => 229
                    [1] => 146
                    [2] => 22
                )

            [hex] => #e59216
        )

)

You can also pointlessly convert the image to pure HTML/CSS.

<?php

use TylerKing\Backlight\Backlight;

$backlight = new Backlight('chrome-icon.png');
file_put_contents('image.html', $backlight->toHTML());

By opening image.html in your browser you will now see the image in HTML/CSS format.
