Problem/Motivation
AVIF image file format is getting traction in browsers' support.
This issue is proposing to implement support to this image format in Drupal core's GD Toolkit.
Done:
- libgd should support the AVIF format - DONE, first release supporting is 2.3.2, released on: March 6, 2021
- a PHP version supporting an IMAGETYPE_AVIF constant - upstream PR https://github.com/php/php-src/pull/5127 - supported with PHP 8.1
- a DrupalCI testbot container should be available for testing.
- #3239935: Refactor ToolkitGdTest
- a bot with a PHP 8.1. instance compiled with
libavifsupport - a PHP 8.2 bot to test getimagesize() on AVIF
- #3116611: Add a requirements check for GD support of allowed image types
- Bots having PHP instances that can fully support AVIF files - currently the bots' PHP, 8.1 and 8.2, cannot save files via
imageavif(), the (bundled?) GD library is missing an appropriate codec supporting the write. (Also see https://bugs.php.net/bug.php?id=81217 , https://github.com/php/php-src/pull/7526 )
Proposed resolution
Extend the GD toolkit to support AVIF too.
Remaining tasks
User interface changes
API changes
Data model changes
