|
The percentage must be in the range [-100, 100] where 0 has no effect. A value of `-100` produces a solid grey image, and a value of `100` produces an over-contrasted image.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Create the filter:
|
||
|
|
|
||
|
|
```go-html-template
|
||
|
|
{{ $filter := images.Contrast -20 }}
|
||
|
|
```
|
||
|
|
|
||
|
|
{{% include "functions/images/_common/apply-image-filter.md" %}}
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
{{< img
|
||
|
|
src="images/examples/zion-national-park.jpg"
|
||
|
|
alt="Zion National Park"
|
||
|
|
filter="Contrast"
|
||
