XF 2.2 WebP Conversion Issue in XenForo 2.2.15

[Freelancer_Titon]

Hello,

I'm trying to develop an add-on for XenForo 2.2.15 that automatically converts uploaded images to WebP format. I've used some code, but it's not working properly.

Here's what I've tried:

1. Added code to the Attachment.php file in the add-on.
2. Attempted to use the Imagick library.
3. Tried reducing the size of the uploaded images.

Problem:

The images are still being uploaded in PNG format and are not being converted to WebP.

Could someone please help me with this? Are there any specific settings or libraries required for WebP conversion in XenForo 2.2.15?

<?php

namespace YourAddonNamespace\XF\Entity;

class Attachment extends XFCP_Attachment
{
    protected function _postSave()
    {
        parent::_postSave();

        if ($this->isInsert() && $this->isImage() && $this->isWebpSupported()) {
            $this->convertToWebp();
        }
    }

    protected function isWebpSupported()
    {
        return function_exists('imagewebp');
    }

    protected function convertToWebp()
    {
        $imagePath = $this->getFilePath();
        $webpPath = $imagePath . '.webp';

        try {
            $image = imagecreatefromstring(file_get_contents($imagePath));
            if (!$image) {
                return;
            }

            ob_start();
            imagewebp($image, null, 80);
            $webpData = ob_get_contents();
            ob_end_clean();
            imagedestroy($image);

            file_put_contents($webpPath, $webpData);

            $this->Data['file_path'] = $webpPath;
            $this->save();

            unlink($imagePath);

        } catch (\Exception $e) {
            \XF::logException($e, false, 'WebP conversion failed: ');
        }
    }
}

Thank you.

Isn't the easier solution here just upgrade to xf2.3.x that has webp support built in?
There is an existing addon that does this already for xf2.2.x.

Indeed, perhaps he doesn't know this is now built in.

Image optimization with WebP support​

Arguably, we could have talked about this in our bumper Boosting performance entry but it wasn't quite ready to be shown at that point. (I started working on it this week and I haven't yet mastered the art of time travel).

Initially the scope of our WebP support in XenForo 2.3 was to merely allow users to upload WebP files and have them correctly displayed inline. This would have been a positive change on its own as the format becomes more prevalent across the web, but it doesn't really do much on its own to solve the issue of disk usage...
