In some cases you want to use the `file://` as base_url when you are for example generating pdf and want to avoid network requests to improve the pdf generation performance:

```yaml
framework:
    assets:
        packages:
            pdf:
                base_url: "file://%kernel.project_dir%/public"
```

usage:

```twig
{{ asset('image.jpg', 'pdf' }}
```
