Gregwar's ImageBundle

GregwarImageBundle provides easy Image manipulation and API for Symfony2 and Twig

Installation

Step 1: Download the GregwarCaptchaBundle

Using the vendors script

Add the following lines to your deps file:

    [GregwarImageBundle]
        git=git://github.com/Gregwar/ImageBundle.git
        target=/bundles/Gregwar/ImageBundle

Now, run the vendors script to download the bundle:

$ php bin/vendors install

Using submodules

If you prefer instead to use git submodules, then run the following:

$ git submodule add git://github.com/Gregwar/ImageBundle.git vendor/bundles/Gregwar/ImageBundle
$ git submodule update --init

Step 2: Configure the Autoloader

Add it to your autoload.pp :

<?php
...
'Gregwar' => __DIR__.'/../vendor/bundles',

Step 3: Enable the bundle

Registers the bundle in your app/AppKernel.php:

<?php
...
public function registerBundles()
{
    $bundles = array(
        ...
        new Gregwar\ImageBundle\GregwarImageBundle(),
        ...
    );
...

Step 4: Configure the bundle and set up the directories

Adds the following configuration to your app/config/config.yml:

gregwar_image: ~

If you want to customize the cache directory name, you can specify it:

gregwar_image:
    cache_dir:  my_cache_dir

Creates the cache directory and change the permissions so the web server can write in it:

mkdir web/cache
chmod 777 web/cache

Usage

Basics

This bundle is based on the Gregwar's Image class and provides simple but powerful Twig extension. You can for instance use it this way:

<img src="{{ image('linux.jpg').resize(100,100).negate }}" />

And that's all ! The helper will automatically create the cached file on-the-fly if it doesn't exists yet.

The available methods are the same as the Gregwar's Image.

Using Image API

The image instance provides also a simple API, you can call some methods to get informations about the handled image:

Image width: {{ image('linux.jpg').width }}px

Manipulating Image in Controllers

The Image Handler is accessible via a service called image.handling. So you can do in your controllers:

<?php
...
$this->get('image.handling')->open('linux.jpg')
    ->grayscale()
    ->rotate(12)
    ->save('out.jpg')

Requirements

GregwarImageBundle needs GD and exif extension for PHP to be installed on the web server
