|
|||
|
|

|
|||
|
|
* - `northwest` (string): Crop from Northwest (top left), may also be just "nw".
|
|||

|
|
*
|
|||
|
|
* **Note about "quality" and "upscaling" options**
|
|||
|
|
*
|
|||
|
|
* ProcessWire doesn't keep separate copies of images with different "quality" or "upscaling" values.
|
|||
|
|
* If you change these and a variation image at the existing dimensions already exists, then you'll still get the old version.
