Silex ImageStack

A PHP image serving framework.

The main goal is to provide a robust framework to create an "on the fly" image thumbnailer generator similar to imagecache / image style in Drupal.

Here is some Silex provider for ImageStack.

See SilexImageStackDemo for more infos.

Installation

composer require quazardous/silex-imagestack

Usage

Here is a Silex bootstrap:

<?php
date_default_timezone_set('Europe/Paris');

include __DIR__.'/../vendor/autoload.php';

use Silex\Application;
$app = new Application();
$app['debug'] = true;

use Sergiors\Silex\Provider\DoctrineCacheServiceProvider;
$app->register(new DoctrineCacheServiceProvider(), [
    // default cache
    'cache.options' => [
        'driver' => 'raw_file',
        'root' => __DIR__ . '/../var/cache/pexels',
    ]
]);

use ImageStack\Provider\ImageStackProvider;
$app->register(new ImageStackProvider(), [
    'image.backends.options' => [
        // http backend on pexels.com
        'web' => [
            'driver' => 'http',
            'root_url' => 'https://static.pexels.com/photos/',

                ['@^original/.*$@', true], // original image
                ['/.*/', false], // trigger a 404
            ],
        ],
        'watermark' => [
            'driver' => 'watermark',
            'watermark' => __DIR__ . '/resources/coffee.png',
            'anchor' => 'bottom right',
        ],
    ],
    'image.storages.options' => [
        // mount the image on the web bootstrap base folder
        'img' => [

            'root' => __DIR__ . '/../web/img/',
            'use_prefix' => true,
            'optimizers' => 'jpeg'
        ],
    ],
    // the stack
    'image.stacks.options' => [
        'pexels' => [
            'backend' => 'web_final',
            'manipulators' => ['thumbnails', 'watermark'],
            'storage' => 'img',
        ],
    ],
    'image.optimizers.options' => [
        'jpeg' => 'jpegtran',
    ],
]);

use ImageStack\Provider\ImagineProvider;
$app->register(new ImagineProvider());

$app['session.storage.handler'] = null; // no sessions

use Silex\Provider\ServiceControllerServiceProvider;
$app->register(new ServiceControllerServiceProvider());

use ImageStack\Provider\ImageControllerProvider;
