The `Fill` method returns a new resource from a [processable image](g) according to the given [processing specification][].
> [!note]
> Use the [`reflect.IsImageResourceProcessable`][] function to verify that an image can be processed.
## Usage
When filling, you must provide both width and height (such as `500x200`) within the specification. `Fill` maintains the original aspect ratio by resizing the image to cover the target area and cropping any overflowing pixels based on the [anchor](#anchor) provided.
```go-html-template
{{ with resources.Get "images/original.jpg" }}
{{ with .Fill "500x200 TopRight" }}
<img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
{{ end }}
{{ end }}
```
In the example above, `"500x200 TopRight"` is the _processing specification.

## Example
```go-html-template
{{ with resources.Get "images/original.jpg" }}
{{ with .Fill "500x200 TopRight" }}
<img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
{{ end }}
{{ end }}
```
{{< img
src="images/examples/zion-national-park.jpg"
alt="Zion National Park"
filter="Process"
filterArgs="fill 500x200 TopRight"
