|
|
||
|
|
action
|
||
|
|
: Applicable to the [`Process`](/methods/resource/process) method only. Specify zero or one of `crop`, `fill`, `fit`, or `resize`. If you specify an action you must also provide dimensions.
|
||
|
|
|
||
|
|
dimensions
|
||
|
|
: Provide width _or_ height when using the [`Resize`](/methods/resource/resize) method, else provide both width _and_ height. See [details](/content-management/image-processing/#dimensions).
|
||
|
|
|
||
|
|
anchor
|
||
|
|
: Use with the [`Crop`](/methods/resource/crop) and [`Fill`](/methods/resource/fill) methods. 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).
|

rotation
|
||
|
|

|
||
|
|
|
||
|
|

|
||
|
