The gamma value must be positive. A value greater than 1 lightens the image, while a value less than 1 darkens the image. The filter has no effect when the gamma value is 1.
|
|
|
|
## Usage
|
|
|
|
Create the filter:
|
|
|
|
```go-html-template
|
|
{{ $filter := images.Gamma 1.667 }}
|
|
```
|
|
|
|
{{% include "functions/images/_common/apply-image-filter.md" %}}
|
|
|
|
## Example
|
|
|
|
{{< img
|
|
src="images/examples/zion-national-park.jpg"
|
|
alt="Zion National Park"
|
|
filter="Gamma"
|
|
filterArgs="1.667"
|
|
example=true
|
|
>}}
