Gregwar's ImageBundle

paypal

GregwarImageBundle provides easy Image manipulation and API for Symfony and Twig

If you use older version than Symfony 4, please use the 2.* version, else you can use 3.*.

Installation

Step 1: Download the GregwarImageBundle

Run the following composer command:

    composer req gregwar/image-bundle

Step 2: 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

You can also enable the exception thrown if the given file does not exist:

gregwar_image:
    throw_exception: true

If you don't throw an exception, you can set the fallback_image, to set the image that should be rendered in this case:

gregwar_image:
    fallback_image: /path/to/your/fallback.jpg

If you have to change directories hierarchy or Web's name (e.g. web => public_html), you can set the web_dir to your new Web path:

gregwar_image:
    web_dir: %kernel.root_dir%/../../public_html

With Symfony Flex

With Symfony Flex architecture, you can create the config/packages/gregwar_image.yaml file with the following contents:

gregwar_image:
    web_dir: %kernel.root_dir%/../public

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.

You can also use the logical file names for bundle resources :

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

If you use web_image() helper, the image file path will be prefixed by the web/ absolute directory of your application:

<!-- The image some/image.jpg will be prefixed by web directory prefix -->
<img src="{{ web_image('some/image.jpg').resize('10%') }}" />

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')

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