The sigma value must be positive, and indicates how much the image will be blurred. The blur-affected radius is approximately 3 times the sigma value.
## Usage
Create the filter:
```go-html-template
{{ $filter := images.GaussianBlur 5 }}
```
{{% include "functions/images/_common/apply-image-filter.md" %}}
## Example
{{< img
src="images/examples/zion-national-park.jpg"
alt="Zion National Park"
filter="GaussianBlur"
filterArgs="5"
example=true
>}}
