Process an image with the given specification. The specification can contain an optional action, one of `crop`, `fill`, `fit`, or `resize`. This means that you can use this method instead of [`Crop`], [`Fill`], [`Fit`], or [`Resize`].
|
||
|
|
|
||
|
|
```go-html-template
|
||
|
|
{{ with resources.Get "images/original.jpg" }}
|
||
|
|
{{ with .Process "crop 200x200" }}
|
||
|
|
<img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
|
||
|
|
{{ end }}
|
||
|
|
{{ end }}
|
||
|
|
```
|
||
|
|
|
||
|
|
You can also use this method to apply simple transformations such as rotation and conversion:
|
||
|
|
|
||
|
|
```go-html-template
|
||
|
|
{{/* Rotate 90 degrees counter-clockwise. */}}
|
||
|
|
{{ $image := $image.Process "r90" }}
|
||
|
|
|
||
|
|
{{/* Convert to WebP. */}}
|
||
|
|
{{ $image := $image.Process "webp" }}
|
||
|
|
```
|
||
|
|
|
||
|
|
The `Process` method is also available as a filter, which is more effective if you need to apply multiple filters to an image. See [`images.Process`].

||

|
{{% include "methods/resource/_common/global-page-remote-resources.md" %}}
