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"
|
