images.Gamma GAMMA
戻り値
images.filter
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:
{{ $filter := images.Gamma 1.667 }}
Apply the filter using the images.Filter function:
{{ with resources.Get "images/original.jpg" }}
{{ with . | images.Filter $filter }}
<img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
{{ end }}
{{ end }}
You can also apply the filter using the Filter method on a Resource object:
{{ with resources.Get "images/original.jpg" }}
{{ with .Filter $filter }}
<img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
{{ end }}
{{ end }}
