Hello, everyone!

Earlier this year, I added support for AVIF images
<https://github.com/libgd/libgd/pull/671> to libgd
<https://github.com/libgd/libgd>. My ultimate goal was to bring support for
this new image format to PHP, so that the world's top CMSs could let sites
serve AVIFs. Recently, @Christoph M. Becker <cmbecker69@gmx.de> and Nikita
have kindly been guiding me as I created a PR to propagate libgd's AVIF
support into PHP's bundled gd fork. This would create two new PHP functions
for systems with gd enabled: imagecreatefromavif() and imageavif().
Additionally it would add AVIF awareness to imagetypes().

This PR <https://github.com/php/php-src/pull/7026> now looks ready to go.
Christoph advised me to write to this list to ask folks to take a look, and
to see if there are any objections to merging it!

If the group approves the first PR, my plan is to finish another PR
<https://github.com/php/php-src/pull/7091> to add AVIF support to the
non-gd image function getimagesize() . In the same PR, I plan to add
support to PHP's internal _php_image_type() function, which is used in
imagecreatefromstring().

Thanks for your help with all of this!


All best,

Ben Morss
