|

#### v0.21.0 - TBD
|
||||
|
||||
* Deprecate the following resize-related functions:
|
||||
`crop`, `embed`, `ignoreAspectRatio`, `max`, `min` and `withoutEnlargement`.
|
||||
Access to these is now via options passed to the `resize` function.
|
||||
For example:
|
||||
`embed('north')` is now `resize(width, height, { fit: 'contain', position: 'north' })`,
|
||||
`crop('attention')` is now `resize(width, height, { fit: 'cover', position: 'attention' })`,
|
||||
`max().withoutEnlargement()` is now `resize(width, height, { fit: 'inside', withoutEnlargement: true })`.
|
||||
[#1135](https://github.com/lovell/sharp/issues/1135)
|
||||
|
||||
* Drop Node 4 support.

* Possible kernels are:
|

* When both a `width` and `height` are provided, the possible methods by which the image should **fit** these are:
|

* - `cover`: Crop to cover both provided dimensions (the default).
|
||||
* - `contain`: Embed within both provided dimensions.
|
||||
* - `fill`: Ignore the aspect ratio of the input and stretch to both provided dimensions.
|
||||
* - `inside`: Preserving aspect ratio, resize the image to be as large as possible while ensuring its dimensions are less than or equal to both those specified.
|
||||
* - `outside`: Preserving aspect ratio, resize the image to be as small as possible while ensuring its dimensions are greater than or equal to both those specified.
|
||||
* Some of these values are based on the [object-fit](https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit) CSS property.
|
||||
*
|
||||
* When using a `fit` of `cover` or `contain`, the default **position** is `centre`. Other options are:
|
||||
* - `sharp.position`: `top`, `right top`, `right`, `right bottom`, `bottom`, `left bottom`, `left`, `left top`.
|
||||
* - `sharp.gravity`: `north`, `northeast`, `east`, `southeast`, `south`, `southwest`, `west`, `northwest`, `center` or `centre`.
|
||||
* - `sharp.strategy`: `cover` only, dynamically crop using either the `entropy` or `attention` strategy.
|
||||
* Some of these values are based on the [object-position](https://developer.mozilla.org/en-US/docs/Web/CSS/object-position) CSS property.
|
||||
*
|
||||
* The experimental strategy-based approach resizes so one dimension is at its target length
|
||||
* then repeatedly ranks edge regions, discarding the edge with the lowest score based on the selected strategy.
|
||||
* - `entropy`: focus on the region with the highest [Shannon entropy](https://en.wikipedia.org/wiki/Entropy_%28information_theory%29).
|
||||
* - `attention`: focus on the region with the highest luminance frequency, colour saturation and presence of skin tones.
|
||||
*
|
||||
* Possible interpolation kernels are:
|
||||
* - `nearest`: Use [nearest neighbour interpolation](http://en.wikipedia.org/wiki/Nearest-neighbor_interpolation).
|
||||
* - `cubic`: Use a [Catmull-Rom spline](https://en.wikipedia.org/wiki/Centripetal_Catmull%E2%80%93Rom_spline).
|
||||
* - `lanczos2`: Use a [Lanczos kernel](https://en.wikipedia.org/wiki/Lanczos_resampling#Lanczos_kernel) with `a=2`.
|
||||
* - `lanczos3`: Use a Lanczos kernel with `a=3` (the default).
