Process an image according to the given [processing specification][]. This versatile method supports the full range of image transformations, including resizing, cropping, rotation, and format conversion, all within a single specification string.
|
|
|
|
```go-html-template
|
|
{{ with resources.Get "images/original.jpg" }}
|
|
{{ with .Process "crop 200x200 TopRight webp q50" }}
|
|
<img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
|
|
{{ end }}
|
|
{{ end }}
|
|
```
|
|
|
|
In the example above, `"crop 200x200 TopRight webp q50"` is the _processing specification_.
|
|
|
|
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`].
