ResponsiveImageBundle

Overview:

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.

Features

• 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
