Feature: #102353 - AVIF support for images generated by GIFBUILDER

Description

GIFBUILDER, the image manipulation library for TypoScript based on GDlib, a PHP extension bundled into PHP, now also supports generating resulting files of type "avif".

AVIF is an image format, that is supported by most modern browsers, and usually has a better compression (= smaller file size) than jpg files.

Important

Before using this feature, please check whether the used operating system actually supports de/encoding AVIF files. Especially Debian 11 (Bullseye) and older or systems forked from that may lack AVIF support.

Impact

If defined via format=avif within a GifBuilder setup, the generated files are now AVIF files instead of png (the default).

It is possible to define the quality of a AVIF image similar to jpg images globally via $TYPO3_CONF_VARS['GFX']['avif_quality'] or via TypoScript's "quality" property on a per-image basis. Via TypoScript it is also possible to use the new property "speed" - see https://www.php.net/manual/en/function.imageavif.php for more details.

Example

page.10 = IMAGE
page.10 {
  file = GIFBUILDER
  file {
    backColor = yellow
    XY = 1024,199
    format = avif
    quality = 44
    speed = 1

    10 = IMAGE
    10.offset = 10,10
    10.file = 1:/my-image.jpg
  }
}

A new test in the Environment module / Install Tool can be used to check if the bundled GDlib extension of your PHP version supports the AVIF image format.
