images.Brightness
Syntax
images.Brightness PERCENTAGE
Returns
images.filter
The percentage must be in the range [-100, 100] where 0 has no effect. A value of -100 produces a solid black image, and a value of 100 produces a solid white image.
Usage
Create the image filter:
{{ $filter := images.Brightness 12 }}
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 }}
