The opacity value must be in the range [0, 1]. A value of `0` produces a transparent image, and a value of `1` produces an opaque image (no transparency).
## Usage
Create the filter:
```go-html-template
{{ $filter := images.Opacity 0.65 }}
```
{{% include "functions/images/_common/apply-image-filter.md" %}}
The `images.Opacity` filter is most useful for target formats such as PNG and WebP that support transparency. If the source image does not support transparency, combine this filter with the `images.Process` filter:
```go-html-template
{{ with resources.Get "images/original.jpg" }}
{{ $filters := slice
(images.Opacity 0.65)
(images.Process "png")
}}
{{ with . | images.Filter $filters }}
<img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
{{ end }}
{{ end }}
```
## Example
{{< img
src="images/examples/zion-national-park.jpg"
alt="Zion National Park"
filter="Opacity"
filterArgs="0.65"
example=true
>}}
