`height` is the Number of pixels high the resultant image should be. Use `null` or `undefined` to auto-scale the height to match the width.
#### crop()
#### crop([gravity])
Crop the resized image to the exact size specified, the default behaviour.
`gravity`, if present, is an attribute of the `sharp.gravity` Object e.g. `sharp.gravity.north`.
Possible values are `north`, `east`, `south`, `west`, `center` and `centre`. The default gravity is `center`/`centre`.
#### max()
Preserving aspect ratio, resize the image to the maximum width or height specified.
