The ResponsiveImageBundle adds the ability to easily create styled and responsive images (scaled, cropped, greyscale) in Symfony3. Responsive images are generated as <picture> tags or as <mg> tags with sizes and scrset attributes.
A crop and focus area widget is also provided to ensure that cropped images always include the most important part of the image.
The bundle uses FlySystem filesystem abstraction layer giving you control over where images are stored. Events are used to drive the system, giving more flexibiltiy and the ability to implement queuing of intensive image processing.
- Image objects are stored via Doctrine ORM
- Handles uploading images to a "FlySystem" filesystem
- Images styles are defined in configuration.
- Breakpoints and pictures sets are defined in configuration
- Handles creation of styled images on the fly (as they are viewed) if using a local filesystem
- Includes a widget to define an image's crop and focus areas giving art direction to styled images
Out of the box, ResponsiveImage bundle should work with minimal configuration.
Download with composer
composer require irishdan/responsive-image-bundle
Enable the bundle and OneupFlysystem in the kernel
// app/AppKernel.php
public function registerBundles()
{
$bundles = array(
// ...
new IrishDan\ResponsiveImageBundle\ResponsiveImageBundle(),
new Oneup\FlysystemBundle\OneupFlysystemBundle(),
);
}Import responsive image services, default and filesystem configuration.
imports:
- { resource: "@ResponsiveImageBundle/Resources/config/services.yml" }
- { resource: "@ResponsiveImageBundle/Resources/config/config.responsive_image_defaults.yml" }
- { resource: "@ResponsiveImageBundle/Resources/config/config.responsive_image_filesystem.yml" }
Import the routing for local on the fly image generation.
responsive_image:
resource: "@ResponsiveImageBundle/Resources/config/routing.yml"
prefix: /Step 3: Install the bundle and generate a ResponsiveImage entity and it's CRUD.
php bin/console responsive_image:generate:entity
php bin/console responsive_image:generate:crudWith the generated image entity and CRUD you can now, create and upload images, apply 'art direction' to images.
Step 4: Define some image styles in your configuration file. (Usually config.yml)
responsive_image:
image_styles:
groovy_thumbnail_style:
effect: crop
width: 180
height: 180
groovy_thumbnail_style_base:
effect: scale
width: 240
groovy_thumbnail_style_mobile:
effect: scale
height:480
groovy_thumbnail_style_mobile:
effect: crop
width: 200
height: 300
greyscale: true
You can now render a styled in your twig template like so:
{{ styled_image(image, 'groovy_thumbnail_style') }}
breakpoints:
base:
media_query: 'min-width: 0px'
mobile:
media_query: 'min-width: 300px'
desktop:
media_query: 'min-width: 1100px'
groovey_picture_set:
fallback: 'groovy_thumbnail_style'
sources:
base: groovy_thumbnail_style_base
mobile: groovy_thumbnail_style_mobile
desktop: groovy_thumbnail_style_desktop
You can now render <picture> responsive images or render responsive background image css in twig templates
<head>
{{ background_responsive_image(image, 'picture_set_name', '#header') }}
</head>
<body>
{{ picture_image(image, 'groovey_picture_set') }}
</body>
responsive_image:
size_sets:
blog_sizes:
fallback: 'groovy_thumbnail_style_base'
sizes:
10vw:
breakpoint: 'mobile'
srcsets: [ 'groovy_thumbnail_style_mobile', 'groovy_thumbnail_style_desktop' ]
You can now render <img> responsive images width srcset and sizes attributes in twig templates.
{{ sizes_image(image, 'blog_sizes') }}
