ImageMagick number of supported formats: 0

I hope this is the right place, I discovered this issue in the linuxserver letsencrypt docker image (https://github.com/linuxserver/docker-letsencrypt/issues/445) and they suggested I post it to you.

Expected Behavior The ImageMagick module is not working, in phpinfo I can see that it says "ImageMagick number of supported formats: 0" this is preventing some functions needing this library from working. If I disable the ImageMagick.ini file the system falls back to GD and works fine. Nothing is logged in the docker or NGINX/php log for this error either. I have deleted and recreated the container and image and tried on 2 different docker installs and issue remains on both.

Current Behavior Images do not load generating a 500 error.

Steps to Reproduce Setup new image Use ImageMagick module (webtress uses this) See 500 error/no image (webtress logs Cannot create thumbnail NoDecodeDelegateForThisImageFormat `PNG'"

they have advised the following:

"We have this php module installed: https://pkgs.alpinelinux.org/package/v3.11/community/x86_64/php7-pecl-imagick It pulls in the imagemagick-libs: https://pkgs.alpinelinux.org/package/v3.11/community/x86_64/imagemagick-libs That's why php is listing the imagemagick library version. But no idea why it's not finding any supported formats."

Any ideas?
