--- title: images.Process description: Returns an image filter that processes the given image using the given specification. categories: [] keywords: [] action: aliases: [] related: - functions/images/Filter - methods/resource/Filter - methods/resource/Process returnType: images.filter signatures: [images.Process SPEC] toc: true --- {{< new-in 0.119.0 >}} This filter has the same options as the [`Process`] method on a `Resource` object, but using it as a filter may be more effective if you need to apply multiple filters to an image. [`Process`]: /methods/resource/process The process specification is a space-delimited, case-insensitive list of one or more of the following in any sequence: action : Specify zero or one of `crop`, `fill`, `fit`, or `resize`. If you specify an action you must also provide dimensions. See [details](content-management/image-processing/#image-processing-methods). ```go-html-template {{ $filter := images.Process "resize 300x" }} ``` dimensions : Required if you specify an action. Provide width _or_ height when using `resize`, else provide both width _and_ height. See [details](/content-management/image-processing/#dimensions). ```go-html-template {{ $filter := images.Process "crop 200x200" }} ``` anchor : Use with the `crop` or `fill` action. Specify zero or one of `TopLeft`, `Top`, `TopRight`, `Left`, `Center`, `Right`, `BottomLeft`, `Bottom`, `BottomRight`, or `Smart`. Default is `Smart`. See [details](/content-management/image-processing/#anchor). ```go-html-template {{ $filter := images.Process "crop 200x200 center" }} ``` rotation : Typically specify zero or one of `r90`, `r180`, or `r270`. Also supports arbitrary rotation angles. See [details](/content-management/image-processing/#rotation). ```go-html-template {{ $filter := images.Process "r90" }} {{ $filter := images.Process "crop 200x200 center r90" }} ``` target format : Specify zero or one of `gif`, `jpeg`, `png`, `tiff`, or `webp`. See [details](/content-management/image-processing/#target-format). ```go-html-template {{ $filter := images.Process "webp" }} {{ $filter := images.Process "crop 200x200 center r90 webp" }} ``` quality : Applicable to JPEG and WebP images. Optionally specify `qN` where `N` is an integer in the range [0, 100]. Default is `75`. See [details](/content-management/image-processing/#quality). ```go-html-template {{ $filter := images.Process "q50" }} {{ $filter := images.Process "crop 200x200 center r90 webp q50" }} ``` hint : Applicable to WebP images and equivalent to the `-preset` flag for the [`cwebp`] encoder. Specify zero or one of `drawing`, `icon`, `photo`, `picture`, or `text`. Default is `photo`. See [details](/content-management/image-processing/#hint). [`cwebp`]: https://developers.google.com/speed/webp/docs/cwebp ```go-html-template {{ $filter := images.Process "webp" "icon" }} {{ $filter := images.Process "crop 200x200 center r90 webp q50 icon" }} ``` background color : When converting a PNG or WebP with transparency to a format that does not support transparency, optionally specify a background color using a 3-digit or a 6-digit hexadecimal color code. Default is `#ffffff` (white). See [details](/content-management/image-processing/#background-color). ```go-html-template {{ $filter := images.Process "jpeg #000" }} {{ $filter := images.Process "crop 200x200 center r90 q50 jpeg #000" }} ``` resampling filter : Typically specify zero or one of `Box`, `Lanczos`, `CatmullRom`, `MitchellNetravali`, `Linear`, or `NearestNeighbor`. Other resampling filters are available. See [details](/content-management/image-processing/#resampling-filter). ```go-html-template {{ $filter := images.Process "resize 300x lanczos" }} {{ $filter := images.Process "resize 300x r90 q50 jpeg #000 lanczos" }} ``` ## Usage Create a filter: ```go-html-template {{ $filter := images.Process "resize 256x q40 webp" }} ``` {{% include "functions/images/_common/apply-image-filter.md" %}} ## Example {{< img src="images/examples/zion-national-park.jpg" alt="Zion National Park" filter="Process" filterArgs="resize 256x q40 webp" example=true >}}
