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:, (*17)
<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., (*18)
The available methods are the same as the Gregwar's Image., (*19)
You can also use the logical file names for bundle resources :, (*20)
<img src="{{ image('@AcmeDemoBundle/Resources/images/linux.jpg').resize(100,100).negate }}" />
Using Image API
The image instance provides also a simple API, you can call some methods to get informations
about the handled image:, (*21)
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:, (*22)
<?php
...
$this->get('image.handling')->open('linux.jpg')
->grayscale()
->rotate(12)
->save('out.jpg')
