WebP support missing

[KennethJoris]

webp image format is supported by most main browsers now. Caniuse

Will Grav add support any soon?

Related to an old request from 2016 #1168

We currently have the same issue as #1168 - we are locked into a specific image library in Grav 1.x, and it doesn't support WebP. With Grav 2.x we plan on revisiting this and updating to a more flexible library.

For future reference:
In your .htaccess file you can check for WebP support and switch to this format if supported :)

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTP_ACCEPT} image/webp
    RewriteCond %{DOCUMENT_ROOT}/$1.webp -f
    RewriteRule ^(path/to/your/images.+)\.(jpe?g|png)$ $1.webp [T=image/webp,E=accept:1]
</IfModule>

<IfModule mod_headers.c>
    Header append Vary Accept env=REDIRECT_accept
</IfModule>

AddType image/webp .webp

@rhukster With this post does this mean GD supports what we need here?
https://www.php.net/manual/en/function.imagewebp.php

If not, I found another post mentioning install libwebp-devel will work in GD.

php -r 'var_dump(gd_info());'
array(12) {
  ["GD Version"]=>
  string(26) "bundled (2.1.0 compatible)"
  ["FreeType Support"]=>
  bool(true)
  ["FreeType Linkage"]=>
  string(13) "with freetype"
  ["GIF Read Support"]=>
  bool(true)
  ["GIF Create Support"]=>
  bool(true)
  ["JPEG Support"]=>
  bool(true)
  ["PNG Support"]=>
  bool(true)
  ["WBMP Support"]=>
  bool(true)
  ["XPM Support"]=>
  bool(false)
  ["XBM Support"]=>
  bool(true)
  ["WebP Support"]=>
  bool(true)
  ["JIS-mapped Japanese Font Support"]=>
  bool(false)
}

Does this provide enough hope that we can start looking at trying to get WebP to work in GD? I'd be willing to provide a little company time towards this, but I want to spend that time wisely
