Imagick not available on FrankenPHP

[SebastianSchoeps]

Just for Google to find this:

I use conversion from PDF to image. This fails on Forge / FrankenPHP because it seems like FrankenPHP doesn't have access to Imagick without a custom build (see dunglas/frankenphp#623).
The conversion fails at src/Conversions/ImageGenerators/Pdf.php:

public function requirementsAreInstalled(): bool
    {
        if (! class_exists(Imagick::class)) {
            return false;
        }

        // ...
    }

I had to go back to Roadrunner.
