Problem/Motivation
Related to #2313075: Allow users to upload webp files in image fields
Since webp is becoming popular, it would be nice if contrib could change the supportedTypes of GDToolkit without needing the extend the class, or even better add support for WebP out of the box.
PS: PHP 5.5 has build in support for WebP and since PHP 5.4 will be abandoned somewhere in 2015, it might be easier to just add support for it.
Proposed resolution
Add usage of IMAGETYPE_WEBP constant support to GDToolkit plugin to allow create Images of WebP format
Detection of format support historically unsupported by core's GD integration so presence of real support (internals of PHP) is out of scope of the issue
Remaining tasks
- agree on feature addition
- commit
User interface changes
ability to create WebP images using image styles
API changes
no
Data model changes
no
Release notes snippet
The GD toolkit and, therefore Image styles, can manage WebP images. Please note that the PHP installation needs to be compiled with the WebP support in order to enable this format.
