php-image-optim

The purpose of this library is to help automate the optimisation of images via the command line in PHP,

Installation:

The library is PSR-0 compliant and the simplest way to install it is via composer, simply add:

{
    "require": {
        "bensquire/php-image-optim": "dev-master"
    }
}

into your composer.json, then run 'composer install' or 'composer update' as required.

Example:

This example demonstrates the optimisation of a PNG file, by chaining several commands together.

<?php
include('./vendor/autoload.php');

$advPng = new \PHPImageOptim\Tools\Png\AdvPng();
$advPng->setBinaryPath('/usr/local/bin/advpng');

$optiPng = new \PHPImageOptim\Tools\Png\OptiPng();
$optiPng->setBinaryPath('/usr/local/bin/optipng');

$pngOut = new \PHPImageOptim\Tools\Png\PngOut();
$pngOut->setBinaryPath('/usr/bin/pngout');

$pngCrush = new \PHPImageOptim\Tools\Png\PngCrush();
$pngCrush->setBinaryPath('/usr/local/bin/pngcrush');

$pngQuant = new \PHPImageOptim\Tools\Png\PngQuant();
$pngQuant->setBinaryPath('/usr/local/bin/pngquant');

$optim = new \PHPImageOptim();
$optim->setImage('/tests/image/lenna.png');
$optim->chainCommand($pngQuant)
    ->chainCommand($advPng)
    ->chainCommand($optiPng)
    ->chainCommand($pngCrush)
    ->chainCommand($pngOut);
$optim->optimise();
