-# Contributing to sharp
-
-Hello, thank you for your interest in helping!
-
-## Submit a new bug report
-
-Please create a [new issue](https://github.com/lovell/sharp/issues/new) containing the steps to reproduce the problem.
-
-If you're having installation problems, please include the output of running `npm install --verbose sharp`.
-
-New bugs are assigned a `triage` label whilst under investigation.
-
-## Submit a new feature request
-
-If a [similar request](https://github.com/lovell/sharp/labels/enhancement) exists,
-it's probably fastest to add a comment to it about your requirement.
-
-Implementation is usually straightforward if libvips
-[already supports](https://www.libvips.org/API/current/func-list.html)
-the feature you need.
-
-## Submit a Pull Request to fix a bug
-
-Thank you! To prevent the problem occurring again, please add unit tests that would have failed.
-
-Please select the `main` branch as the destination for your Pull Request so your fix can be included in the next minor release.
-
-Please squash your changes into a single commit using a command like `git rebase -i upstream/main`.
-
-To test C++ changes, you can compile the module using `npm install --build-from-source` and then run the tests using `npm test`.
-
-## Submit a Pull Request with a new feature
-
-Please add JavaScript [unit tests](https://github.com/lovell/sharp/tree/main/test/unit) to cover your new feature.
-A test coverage report for the JavaScript code is generated in the `coverage/lcov-report` directory.
-Please also update the [TypeScript definitions](https://github.com/lovell/sharp/tree/main/lib/index.d.ts), along with the [type definition tests](https://github.com/lovell/sharp/tree/main/test/types/sharp.test-d.ts).
-
-Where possible, the functional tests use gradient-based perceptual hashes
-based on [dHash](http://www.hackerfactor.com/blog/index.php?/archives/529-Kind-of-Like-That.html)
-to compare expected vs actual images.
-
-You deserve to add your details to the [list of contributors](https://github.com/lovell/sharp/blob/main/package.json#L5).
-
-Any change that modifies the existing public API should be added to the relevant work-in-progress branch for inclusion in the next major release.
-
-Please squash your changes into a single commit using a command like `git rebase -i upstream/<wip-branch>`.
-
-### Add a new public method
-
-The API tries to be as fluent as possible.
-Image processing concepts follow the naming conventions from libvips and, to a lesser extent, ImageMagick.
-
-Most methods have optional parameters and assume sensible defaults.
-Please ensure backwards compatibility where possible.
-
-Feel free to create a [new issue](https://github.com/lovell/sharp/issues/new) to gather feedback on a potential API change.
-
-### Remove an existing public method
-
-A method to be removed should be deprecated in the next major version then removed in the following major version.
-
-By way of example, the `background()` method present in v0.20.0 was deprecated in v0.21.0 and removed in v0.22.0.
-
-## Documentation
-
-The public API is documented with [JSDoc](https://jsdoc.app/) annotated comments.
-
-These can be converted to Markdown by running:
-```sh
-npm run docs-build
-```
-
-Please include documentation updates in any Pull Request that modifies the public API.
-
-## Run the tests
-
-### Functional tests and static code analysis
-
-```sh
-npm test
-```
-
-### Memory leak tests
-
-Requires [Valgrind](http://valgrind.org/).
-
-```sh
-npm run test-leak
-```
-
-## Finally
-
-Please feel free to ask any questions via a
-[new issue](https://github.com/lovell/sharp/issues/new).
-
-If you're unable to post details publicly, please
-[e-mail](https://github.com/lovell/sharp/blob/main/package.json#L5)
-for private, paid consulting.

-
-<!-- Please try to answer as many of these questions as possible. -->
-
-## Possible install-time or require-time problem
-
-<!-- Please place an [x] in the box to confirm. -->
-
- [ ] I have read and understood all of the [documentation relating to installation](https://sharp.pixelplumbing.com/install).
- [ ] I have searched for known bugs relating to this problem in my choice of package manager.
-
-You must confirm both of these before continuing.
-
-### Are you using the latest version of sharp?
-
-<!-- Please place an [x] in the box to confirm. -->
-
- [ ] I am using the latest version of `sharp` as reported by `npm view sharp dist-tags.latest`.
-
-If you cannot confirm this, please upgrade to the latest version and try again before opening an issue.
-
-If you are using another package which depends on a version of `sharp` that is not the latest,
-please open an issue against that package instead.
-
-### Are you using a supported runtime?
-
-<!-- Please place an [x] in the relevant box to confirm. -->
-
- [ ] I am using Node.js with a version that satisfies `^18.17.0 || ^20.3.0 || >=21.0.0`
- [ ] I am using Deno
- [ ] I am using Bun
-
-If you cannot confirm any of these,
-please upgrade to the latest version
-and try again before opening an issue.
-
-### Are you using a supported package manager and installing optional dependencies?
-
-<!-- Please place an [x] in the relevant box to confirm. -->
-
- [ ] I am using npm >= 10.1.0 with `--include=optional`
- [ ] I am using yarn >= 3.2.0
- [ ] I am using pnpm >= 7.1.0 with `--no-optional=false`
- [ ] I am using Deno
- [ ] I am using Bun
-
-If you cannot confirm any of these, please upgrade to the latest version of your chosen package manager
-and ensure you are allowing the installation of optional or multi-platform dependencies before opening an issue.
-
-### What is the complete error message, including the full stack trace?
-
-<!-- Please provide the error message and stack trace here. -->

-
-<!-- If this issue relates to installation, please use https://github.com/lovell/sharp/issues/new?labels=installation&template=installation.md instead. -->
-
-## Possible bug
-
-### Is this a possible bug in a feature of sharp, unrelated to installation?
-
-<!-- Please place an [x] in the box to confirm. -->
-
- [ ] Running `npm install sharp` completes without error.
- [ ] Running `node -e "require('sharp')"` completes without error.
-
-If you cannot confirm both of these, please open an [installation issue](https://github.com/lovell/sharp/issues/new?labels=installation&template=installation.md) instead.
-
-### Are you using the latest version of sharp?
-
-<!-- Please place an [x] in the box to confirm. -->
-
- [ ] I am using the latest version of `sharp` as reported by `npm view sharp dist-tags.latest`.
-
-If you cannot confirm this, please upgrade to the latest version and try again before opening an issue.
-
-If you are using another package which depends on a version of `sharp` that is not the latest, please open an issue against that package instead.
-
-### What is the output of running `npx envinfo --binaries --system --npmPackages=sharp --npmGlobalPackages=sharp`?
-
-<!-- Please provide output of the above command here. -->
-
-### Does this problem relate to file caching?
-
-The default behaviour of libvips is to cache input files, which can lead to `EBUSY` or `EPERM` errors on Windows.
-Use [`sharp.cache(false)`](https://sharp.pixelplumbing.com/api-utility#cache) to switch this feature off.
-
- [ ] Adding `sharp.cache(false)` does not fix this problem.
-
-### Does this problem relate to images appearing to have been rotated by 90 degrees?
-
-Images that contain EXIF Orientation metadata are not auto-oriented. By default, EXIF metadata is removed.
-
- To auto-orient pixel values use the parameter-less [`rotate()`](https://sharp.pixelplumbing.com/api-operation#rotate) operation.
- To retain EXIF Orientation use [`keepExif()`](https://sharp.pixelplumbing.com/api-output#keepexif).
-
- [ ] Using `rotate()` or `keepExif()` does not fix this problem.
-
-### What are the steps to reproduce?
-
-<!-- Please enter steps to reproduce here. -->
-
-### What is the expected behaviour?
-
-<!-- Please enter the expected behaviour here. -->
-
-### Please provide a minimal, standalone code sample, without other dependencies, that demonstrates this problem

+_adj_

-The typical use case for this high speed Node-API module
-is to convert large images in common formats to
-smaller, web-friendly JPEG, PNG, WebP, GIF and AVIF images of varying dimensions.
+1. clearly defined; distinct: a sharp photographic image. 
+2. quick, brisk, or spirited. 
+3. shrewd or astute: a sharp bargainer. 
+4. (Informal.) very stylish: a sharp dresser; a sharp jacket. 

-It can be used with all JavaScript runtimes
-that provide support for Node-API v9, including
-Node.js (^18.17.0 or >= 20.3.0), Deno and Bun.
+The typical use case for this high performance Node.js module is to convert a large JPEG image to smaller JPEG images of varying dimensions.

-Resizing an image is typically 4x-5x faster than using the
-quickest ImageMagick and GraphicsMagick settings
-due to its use of [libvips](https://github.com/libvips/libvips).
+It is somewhat opinionated in that it only deals with JPEG images, always obeys the requested dimensions by either cropping or embedding and insists on a mild sharpen of the resulting image.

-Colour spaces, embedded ICC profiles and alpha transparency channels are all handled correctly.
-Lanczos resampling ensures quality is not sacrificed for speed.
+Under the hood you'll find the blazingly fast [libvips](https://github.com/jcupitt/libvips) image processing library, originally created in 1989 at Birkbeck College and currently maintained by the University of Southampton.

-As well as image resizing, operations such as
-rotation, extraction, compositing and gamma correction are available.
+Speed is typically 4x faster than the imagemagick equivalent.

-Most modern macOS, Windows and Linux systems
-do not require any additional install or runtime dependencies.
+## Prerequisites

-## Documentation
+Requires node-gyp and libvips-dev to build.

-Visit [sharp.pixelplumbing.com](https://sharp.pixelplumbing.com/) for complete
-[installation instructions](https://sharp.pixelplumbing.com/install),
-[API documentation](https://sharp.pixelplumbing.com/api-constructor),
-[benchmark tests](https://sharp.pixelplumbing.com/performance) and
-[changelog](https://sharp.pixelplumbing.com/changelog).
+	sudo npm install -g node-gyp
+	sudo apt-get install libvips-dev

-## Examples
+Requires vips-7.xx.pc (installed with libvips-dev) to be symlinked as /usr/lib/pkgconfig/vips.pc
+
+Ubuntu 12.04 LTS:
+
+	sudo ln -s /usr/lib/pkgconfig/vips-7.26.pc /usr/lib/pkgconfig/vips.pc
+
+Ubuntu 13.04 (64-bit):
+
+	sudo ln -s /usr/lib/x86_64-linux-gnu/pkgconfig/vips-7.28.pc /usr/lib/pkgconfig/vips.pc
+
+## Install

-```sh
 	npm install sharp
-```
+
+## Usage
+
+  var sharp = require("sharp");
+
+### crop(inputPath, outputPath, width, height, callback)
+
+Scale and crop JPEG `inputPath` to `width` x `height` and write JPEG to `outputPath` calling `callback` when complete.
+
+Example:

 ```javascript
-const sharp = require('sharp');
-```
-
-### Callback
-
-```javascript
-sharp(inputBuffer)
-  .resize(320, 240)
-  .toFile('output.webp', (err, info) => { ... });
-```
-
-### Promise
-
-```javascript
-sharp('input.jpg')
-  .rotate()
-  .resize(200)
-  .jpeg({ mozjpeg: true })
-  .toBuffer()
-  .then( data => { ... })
-  .catch( err => { ... });
-```
-
-### Async/await
-
-```javascript
-const semiTransparentRedPng = await sharp({
-  create: {
-    width: 48,
-    height: 48,
-    channels: 4,
-    background: { r: 255, g: 0, b: 0, alpha: 0.5 }
+sharp.crop("input.jpg", "output.jpg", 300, 200, function(err) {
+  if (err) {
+    throw err;
  }
-})
-  .png()
-  .toBuffer();
+  // output.jpg is a 300 pixels wide and 200 pixels high image
+  // containing a scaled and cropped version of input.jpg
+});
 ```

-### Stream
+### embedWhite(inputPath, outputPath, width, height, callback)
+
+Scale and embed JPEG `inputPath` to `width` x `height` using a white canvas and write JPEG to `outputPath` calling `callback` when complete.

 ```javascript
-const roundedCorners = Buffer.from(
-  '<svg><rect x="0" y="0" width="200" height="200" rx="50" ry="50"/></svg>'
-);
-
-const roundedCornerResizer =
-  sharp()
-    .resize(200, 200)
-    .composite([{
-      input: roundedCorners,
-      blend: 'dest-in'
-    }])
-    .png();
-
-readableStream

-
-## removeAlpha
-> removeAlpha() ⇒ <code>Sharp</code>
-
-Remove alpha channels, if any. This is a no-op if the image does not have an alpha channel.
-
-See also [flatten](/api-operation#flatten).
-
-
-**Example**  
-```js
-sharp('rgba.png')
-  .removeAlpha()
-  .toFile('rgb.png', function(err, info) {
-    // rgb.png is a 3 channel image without an alpha channel
-  });
-```
-
-
-## ensureAlpha
-> ensureAlpha([alpha]) ⇒ <code>Sharp</code>
-
-Ensure the output image has an alpha transparency channel.
-If missing, the added alpha channel will have the specified
-transparency level, defaulting to fully-opaque (1).
-This is a no-op if the image already has an alpha channel.
-
-
-**Throws**:
-
- <code>Error</code> Invalid alpha transparency level
-
-**Since**: 0.21.2  
-
-| Param | Type | Default | Description |
-| --- | --- | --- | --- |
-| [alpha] | <code>number</code> | <code>1</code> | alpha transparency level (0=fully-transparent, 1=fully-opaque) |
-
-**Example**  
-```js
-// rgba.png will be a 4 channel image with a fully-opaque alpha channel
-await sharp('rgb.jpg')
-  .ensureAlpha()
-  .toFile('rgba.png')
-```
-**Example**  
-```js
-// rgba is a 4 channel image with a fully-transparent alpha channel
-const rgba = await sharp(rgb)
-  .ensureAlpha(0)
-  .toBuffer();
-```
-
-
-## extractChannel
-> extractChannel(channel) ⇒ <code>Sharp</code>
-
-Extract a single channel from a multi-channel image.
-
-
-**Throws**:
-
- <code>Error</code> Invalid channel
-
-
-| Param | Type | Description |
-| --- | --- | --- |
-| channel | <code>number</code> \| <code>string</code> | zero-indexed channel/band number to extract, or `red`, `green`, `blue` or `alpha`. |
-
-**Example**  
-```js
-// green.jpg is a greyscale image containing the green channel of the input
-await sharp(input)
-  .extractChannel('green')
-  .toFile('green.jpg');
-```
-**Example**  
-```js
-// red1 is the red value of the first pixel, red2 the second pixel etc.
-const [red1, red2, ...] = await sharp(input)
-  .extractChannel(0)
-  .raw()
-  .toBuffer();
-```
-
-
-## joinChannel
-> joinChannel(images, options) ⇒ <code>Sharp</code>
-
-Join one or more channels to the image.
-The meaning of the added channels depends on the output colourspace, set with `toColourspace()`.
-By default the output image will be web-friendly sRGB, with additional channels interpreted as alpha channels.
-Channel ordering follows vips convention:
- sRGB: 0: Red, 1: Green, 2: Blue, 3: Alpha.
- CMYK: 0: Magenta, 1: Cyan, 2: Yellow, 3: Black, 4: Alpha.
-
-Buffers may be any of the image formats supported by sharp.
-For raw pixel input, the `options` object should contain a `raw` attribute, which follows the format of the attribute of the same name in the `sharp()` constructor.
-
-
-**Throws**:
-
- <code>Error</code> Invalid parameters
-
-
-| Param | Type | Description |
-| --- | --- | --- |
-| images | <code>Array.&lt;(string\|Buffer)&gt;</code> \| <code>string</code> \| <code>Buffer</code> | one or more images (file paths, Buffers). |
-| options | <code>Object</code> | image options, see `sharp()` constructor. |
-
-
-
-## bandbool
-> bandbool(boolOp) ⇒ <code>Sharp</code>
-
-Perform a bitwise boolean operation on all input image channels (bands) to produce a single channel output image.
-
-
-**Throws**:
-
- <code>Error</code> Invalid parameters
-
-
-| Param | Type | Description |
-| --- | --- | --- |
-| boolOp | <code>string</code> | one of `and`, `or` or `eor` to perform that bitwise operation, like the C logic operators `&`, `|` and `^` respectively. |
-
-**Example**  
-```js
-sharp('3-channel-rgb-input.png')
-  .bandbool(sharp.bool.and)
-  .toFile('1-channel-output.png', function (err, info) {
-    // The output will be a single channel image where each pixel `P = R & G & B`.
-    // If `I(1,1) = [247, 170, 14] = [0b11110111, 0b10101010, 0b00001111]`
-    // then `O(1,1) = 0b11110111 & 0b10101010 & 0b00001111 = 0b00000010 = 2`.
-  });

-
-## greyscale
-> greyscale([greyscale]) ⇒ <code>Sharp</code>
-
-Convert to 8-bit greyscale; 256 shades of grey.
-This is a linear operation. If the input image is in a non-linear colour space such as sRGB, use `gamma()` with `greyscale()` for the best results.
-By default the output image will be web-friendly sRGB and contain three (identical) colour channels.
-This may be overridden by other sharp operations such as `toColourspace('b-w')`,
-which will produce an output image containing one colour channel.
-An alpha channel may be present, and will be unchanged by the operation.

-## composite
-> composite(images) ⇒ <code>Sharp</code>
-
-Composite image(s) over the processed (resized, extracted etc.) image.
-
-The images to composite must be the same size or smaller than the processed image.

-
-Other operations in the same processing pipeline (e.g. resize, rotate, flip,
-flop, extract) will always be applied to the input image before composition.
-
-The `blend` option can be one of `clear`, `source`, `over`, `in`, `out`, `atop`,
-`dest`, `dest-over`, `dest-in`, `dest-out`, `dest-atop`,
-`xor`, `add`, `saturate`, `multiply`, `screen`, `overlay`, `darken`, `lighten`,
-`colour-dodge`, `color-dodge`, `colour-burn`,`color-burn`,
-`hard-light`, `soft-light`, `difference`, `exclusion`.

-## clone
-> clone() ⇒ [<code>Sharp</code>](#Sharp)
-
-Take a "snapshot" of the Sharp instance, returning a new instance.
-Cloned instances inherit the input of their parent instance.
-This allows multiple output Streams and therefore multiple processing pipelines to share a single input Stream.
-
-
-**Example**  
-```js
-const pipeline = sharp().rotate();
-pipeline.clone().resize(800, 600).pipe(firstWritableStream);
-pipeline.clone().extract({ left: 20, top: 20, width: 100, height: 100 }).pipe(secondWritableStream);
-readableStream.pipe(pipeline);
-// firstWritableStream receives auto-rotated, resized readableStream
-// secondWritableStream receives auto-rotated, extracted region of readableStream
-```
-**Example**  
-```js
-// Create a pipeline that will download an image, resize it and format it to different files
-// Using Promises to know when the pipeline is complete
-const fs = require("fs");
-const got = require("got");
-const sharpStream = sharp({ failOn: 'none' });
-
-const promises = [];

-## rotate
-> rotate([angle], [options]) ⇒ <code>Sharp</code>
-
-Rotate the output image.
-
-The provided angle is converted to a valid positive degree rotation.
-For example, `-450` will produce a 270 degree rotation.
-
-When rotating by an angle other than a multiple of 90,
-the background colour can be provided with the `background` option.
-
-For backwards compatibility, if no angle is provided, `.autoOrient()` will be called.
-
-Only one rotation can occur per pipeline (aside from an initial call without
-arguments to orient via EXIF data). Previous calls to `rotate` in the same
-pipeline will be ignored.
-
-Multi-page images can only be rotated by 180 degrees.
-
-Method order is important when rotating, resizing and/or extracting regions,
-for example `.rotate(x).extract(y)` will produce a different result to `.extract(y).rotate(x)`.
-
-
-**Throws**:
-
- <code>Error</code> Invalid parameters
-
-
-| Param | Type | Default | Description |
-| --- | --- | --- | --- |
-| [angle] | <code>number</code> | <code>auto</code> | angle of rotation. |
-| [options] | <code>Object</code> |  | if present, is an Object with optional attributes. |
-| [options.background] | <code>string</code> \| <code>Object</code> | <code>&quot;\&quot;#000000\&quot;&quot;</code> | parsed by the [color](https://www.npmjs.org/package/color) module to extract values for red, green, blue and alpha. |
-
-**Example**  
-```js
-const rotateThenResize = await sharp(input)
-  .rotate(90)
-  .resize({ width: 16, height: 8, fit: 'fill' })
-  .toBuffer();
-const resizeThenRotate = await sharp(input)
-  .resize({ width: 16, height: 8, fit: 'fill' })
-  .rotate(90)
-  .toBuffer();
-```
-
-
-## autoOrient
-> autoOrient() ⇒ <code>Sharp</code>
-
-Auto-orient based on the EXIF `Orientation` tag, then remove the tag.
-Mirroring is supported and may infer the use of a flip operation.
-
-Previous or subsequent use of `rotate(angle)` and either `flip()` or `flop()`
-will logically occur after auto-orientation, regardless of call order.
-
-
-**Example**  
-```js
-const output = await sharp(input).autoOrient().toBuffer();
-```
-**Example**  
-```js
-const pipeline = sharp()
-  .autoOrient()
-  .resize(null, 200)
-  .toBuffer(function (err, outputBuffer, info) {
-    // outputBuffer contains 200px high JPEG image data,
-    // auto-oriented using EXIF Orientation tag
-    // info.width and info.height contain the dimensions of the resized image
-  });
-readableStream.pipe(pipeline);
-```
-
-
-## flip
-> flip([flip]) ⇒ <code>Sharp</code>
-
-Mirror the image vertically (up-down) about the x-axis.
-This always occurs before rotation, if any.
-
-This operation does not work correctly with multi-page images.
-
-
-
-| Param | Type | Default |
-| --- | --- | --- |
-| [flip] | <code>Boolean</code> | <code>true</code> | 
-
-**Example**  
-```js
-const output = await sharp(input).flip().toBuffer();
-```
-
-
-## flop
-> flop([flop]) ⇒ <code>Sharp</code>
-
-Mirror the image horizontally (left-right) about the y-axis.
-This always occurs before rotation, if any.
-
-
-
-| Param | Type | Default |
-| --- | --- | --- |
-| [flop] | <code>Boolean</code> | <code>true</code> | 
-
-**Example**  
-```js
-const output = await sharp(input).flop().toBuffer();
-```
-
-
-## affine
-> affine(matrix, [options]) ⇒ <code>Sharp</code>
-
-Perform an affine transform on an image. This operation will always occur after resizing, extraction and rotation, if any.
-
-You must provide an array of length 4 or a 2x2 affine transformation matrix.

-title: Resizing images
---
-
-## resize
-> resize([width], [height], [options]) ⇒ <code>Sharp</code>
-
-Resize image to `width`, `height` or `width x height`.
-
-When both a `width` and `height` are provided, the possible methods by which the image should **fit** these are:
- `cover`: (default) Preserving aspect ratio, attempt to ensure the image covers both provided dimensions by cropping/clipping to fit.
- `contain`: Preserving aspect ratio, contain within both provided dimensions using "letterboxing" where necessary.
- `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.
-
-<img alt="Examples of various values for the fit property when resizing" width="100%" style="aspect-ratio: 998/243" src="/api-resize-fit.svg">
-
-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 strategy-based approach initially 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 downsizing kernels are:
- `nearest`: Use [nearest neighbour interpolation](http://en.wikipedia.org/wiki/Nearest-neighbor_interpolation).
- `linear`: Use a [triangle filter](https://en.wikipedia.org/wiki/Triangular_function).
- `cubic`: Use a [Catmull-Rom spline](https://en.wikipedia.org/wiki/Centripetal_Catmull%E2%80%93Rom_spline).
- `mitchell`: Use a [Mitchell-Netravali spline](https://www.cs.utexas.edu/~fussell/courses/cs384g-fall2013/lectures/mitchell/Mitchell.pdf).
- `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).
- `mks2013`: Use a [Magic Kernel Sharp](https://johncostella.com/magic/mks.pdf) 2013 kernel, as adopted by Facebook.
- `mks2021`: Use a Magic Kernel Sharp 2021 kernel, with more accurate (reduced) sharpening than the 2013 version.
-
-When upsampling, these kernels map to `nearest`, `linear` and `cubic` interpolators.
-Downsampling kernels without a matching upsampling interpolator map to `cubic`.
-
-Only one resize can occur per pipeline.
-Previous calls to `resize` in the same pipeline will be ignored.

-| [height] | <code>number</code> |  | How many pixels high the resultant image should be. Use `null` or `undefined` to auto-scale the height to match the width. |
-| [options] | <code>Object</code> |  |  |
-| [options.width] | <code>number</code> |  | An alternative means of specifying `width`. If both are present this takes priority. |
-| [options.height] | <code>number</code> |  | An alternative means of specifying `height`. If both are present this takes priority. |
-| [options.fit] | <code>String</code> | <code>&#x27;cover&#x27;</code> | How the image should be resized/cropped to fit the target dimension(s), one of `cover`, `contain`, `fill`, `inside` or `outside`. |

-| [options.kernel] | <code>String</code> | <code>&#x27;lanczos3&#x27;</code> | The kernel to use for image reduction and the inferred interpolator to use for upsampling. Use the `fastShrinkOnLoad` option to control kernel vs shrink-on-load. |
-| [options.withoutEnlargement] | <code>Boolean</code> | <code>false</code> | Do not scale up if the width *or* height are already less than the target dimensions, equivalent to GraphicsMagick's `>` geometry option. This may result in output dimensions smaller than the target dimensions. |
-| [options.withoutReduction] | <code>Boolean</code> | <code>false</code> | Do not scale down if the width *or* height are already greater than the target dimensions, equivalent to GraphicsMagick's `<` geometry option. This may still result in a crop to reach the target dimensions. |
-| [options.fastShrinkOnLoad] | <code>Boolean</code> | <code>true</code> | Take greater advantage of the JPEG and WebP shrink-on-load feature, which can lead to a slight moiré pattern or round-down of an auto-scaled dimension. |

-## concurrency
-> concurrency([concurrency]) ⇒ <code>number</code>
-
-Gets or, when a concurrency is provided, sets
-the maximum number of threads _libvips_ should use to process _each image_.
-These are from a thread pool managed by glib,
-which helps avoid the overhead of creating new threads.
-
-This method always returns the current concurrency.
-
-The default value is the number of CPU cores,
-except when using glibc-based Linux without jemalloc,
-where the default is `1` to help reduce memory fragmentation.
-
-A value of `0` will reset this to the number of CPU cores.
-
-Some image format libraries spawn additional threads,
-e.g. libaom manages its own 4 threads when encoding AVIF images,
-and these are independent of the value set here.

-title: "High performance Node.js image processing"
---
-
-<img src="/sharp-logo.svg" width="160" height="160" alt="sharp logo" align="right">
-
-The typical use case for this high speed Node-API module
-is to convert large images in common formats to
-smaller, web-friendly JPEG, PNG, WebP, GIF and AVIF images of varying dimensions.
-
-It can be used with all JavaScript runtimes
-that provide support for Node-API v9, including
-Node.js >= 18.17.0, Deno and Bun.
-
-Resizing an image is typically 4x-5x faster than using the
-quickest ImageMagick and GraphicsMagick settings
-due to its use of [libvips](https://github.com/libvips/libvips).
-
-Colour spaces, embedded ICC profiles and alpha transparency channels are all handled correctly.
-Lanczos resampling ensures quality is not sacrificed for speed.
-
-As well as image resizing, operations such as
-rotation, extraction, compositing and gamma correction are available.
-
-Most modern macOS, Windows and Linux systems
-do not require any additional install or runtime dependencies.
-
-```sh
-npm install sharp
-```
-
-## Formats
-
-This module supports reading JPEG, PNG, WebP, GIF, AVIF, TIFF and SVG images.
-
-Output images can be in JPEG, PNG, WebP, GIF, AVIF and TIFF formats as well as uncompressed raw pixel data.
-
-Streams, Buffer objects and the filesystem can be used for input and output.
-
-A single input Stream can be split into multiple processing pipelines and output Streams.
-
-Deep Zoom image pyramids can be generated,
-suitable for use with "slippy map" tile viewers like
-[OpenSeadragon](https://github.com/openseadragon/openseadragon).
-
-## Fast
-
-This module is powered by the blazingly fast
-[libvips](https://github.com/libvips/libvips) image processing library,
-originally created in 1989 at Birkbeck College
-and currently maintained by a small team led by
-[John Cupitt](https://github.com/jcupitt).
-
-Only small regions of uncompressed image data
-are held in memory and processed at a time,
-taking full advantage of multiple CPU cores and L1/L2/L3 cache.
-
-Everything remains non-blocking thanks to _libuv_,
-no child processes are spawned and Promises/async/await are supported.
-
-## Optimal
-
-The features of `mozjpeg` and `pngquant` can be used
-to optimise the file size of JPEG and PNG images respectively,
-without having to invoke separate `imagemin` processes.
-
-Huffman tables are optimised when generating JPEG output images
-without having to use separate command line tools like
-[jpegoptim](https://github.com/tjko/jpegoptim) and
-[jpegtran](http://jpegclub.org/jpegtran/).
-
-PNG filtering is disabled by default,
-which for diagrams and line art often produces the same result
-as [pngcrush](https://pmt.sourceforge.io/pngcrush/).
-
-The file size of animated GIF output is optimised
-without having to use separate command line tools such as
-[gifsicle](https://www.lcdf.org/gifsicle/).

-title: Installation
---
-
-Works with your choice of JavaScript package manager.
-
-:::caution
-Please ensure your package manager is configured to install optional dependencies
-:::
-
-If a package manager lockfile must support multiple platforms,
-please see the [cross-platform](#cross-platform) section
-to help decide which package manager is appropriate.
-
-```sh
-npm install sharp
-```
-
-```sh
-pnpm add sharp
-```
-
-When using `pnpm`, you may need to add `sharp` to
-[ignoredBuiltDependencies](https://pnpm.io/settings#ignoredbuiltdependencies)
-to silence warnings.
-
-```sh
-yarn add sharp
-```
-
-```sh
-bun add sharp
-```
-
-```sh
-deno run --allow-ffi ...
-```
-
-## Prerequisites
-
-* Node-API v9 compatible runtime e.g. Node.js ^18.17.0 or >=20.3.0.
-
-## Prebuilt binaries
-
-Ready-compiled sharp and libvips binaries are provided for use on the most common platforms:
-
-* macOS x64 (>= 10.15)
-* macOS ARM64
-* Linux ARM (glibc >= 2.31)
-* Linux ARM64 (glibc >= 2.26, musl >= 1.2.2)
-* Linux ppc64 (glibc >= 2.31)
-* Linux s390x (glibc >= 2.31)
-* Linux x64 (glibc >= 2.26, musl >= 1.2.2, CPU with SSE4.2)
-* Windows x64
-* Windows x86
-* Windows ARM64 (experimental, CPU with ARMv8.4 required for all features)
-
-This provides support for the
-JPEG, PNG, WebP, AVIF (limited to 8-bit depth), TIFF, GIF and SVG (input) image formats.
-
-## Cross-platform
-
-At install time, package managers will automatically select prebuilt binaries
-for the current OS platform and CPU architecture, where available.
-
-Some package managers support multiple platforms and architectures
-within the same installation tree and/or using the same lockfile.
-
-### npm v10+
-
-:::caution
-npm `package-lock.json` files shared by multiple platforms can cause installation problems due to [npm bug #4828](https://github.com/npm/cli/issues/4828)
-:::
-
-Provides limited support via `--os`, `--cpu` and `--libc` flags.
-
-To support macOS with Intel x64 and ARM64 CPUs:
-```sh
-npm install --cpu=x64 --os=darwin sharp
-npm install --cpu=arm64 --os=darwin sharp
-```
-
-When the cross-target is Linux, the C standard library must be specified.
-
-To support glibc (e.g. Debian) and musl (e.g. Alpine) Linux with Intel x64 CPUs:
-```sh
-npm install --cpu=x64 --os=linux --libc=glibc sharp
-npm install --cpu=x64 --os=linux --libc=musl sharp
-```
-
-### yarn v3+
-
-Use the [supportedArchitectures](https://yarnpkg.com/configuration/yarnrc#supportedArchitectures) configuration.
-
-### pnpm v8+
-
-Use the [supportedArchitectures](https://pnpm.io/settings#supportedarchitectures) configuration.
-
-## Custom libvips
-
-To use a custom, globally-installed version of libvips instead of the provided binaries,
-make sure it is at least the version listed under `config.libvips` in the `package.json` file
-and that it can be located using `pkg-config --modversion vips-cpp`.
-
-For help compiling libvips and its dependencies, please see
-[building libvips from source](https://www.libvips.org/install.html#building-libvips-from-source).
-
-The use of a globally-installed libvips is unsupported on Windows
-and on macOS when running Node.js under Rosetta.
-
-## Building from source
-
-This module will be compiled from source at `npm install` time when:
-
-* a globally-installed libvips is detected, or
-* when the `npm install --build-from-source` flag is used.
-
-The logic to detect a globally-installed libvips can be skipped by setting the
-`SHARP_IGNORE_GLOBAL_LIBVIPS` (never try to use it) or
-`SHARP_FORCE_GLOBAL_LIBVIPS` (always try to use it, even when missing or outdated)
-environment variables.
-
-Building from source requires:
-
-* C++17 compiler
-* [node-addon-api](https://www.npmjs.com/package/node-addon-api) version 7+
-* [node-gyp](https://github.com/nodejs/node-gyp#installation) version 9+ and its dependencies
-
-There is an install-time check for these dependencies.
-If `node-addon-api` or `node-gyp` cannot be found, try adding them via:
-
-```sh
-npm install --save node-addon-api node-gyp
-```
-
-When using `pnpm`, you may need to add `sharp` to
-[onlyBuiltDependencies](https://pnpm.io/settings#onlybuiltdependencies)
-to ensure the installation script can be run.
-
-For cross-compiling, the `--platform`, `--arch` and `--libc` npm flags
-(or the `npm_config_platform`, `npm_config_arch` and `npm_config_libc` environment variables)
-can be used to configure the target environment.
-
-## WebAssembly
-
-Experimental support is provided for runtime environments that provide
-multi-threaded Wasm via Workers.
-
-Use in web browsers is unsupported.
-
-Native text rendering is unsupported.
-
-[Tile-based output](/api-output#tile) is unsupported.
-
-```sh
-npm install --cpu=wasm32 sharp
-```
-
-## FreeBSD
-
-The `vips` package must be installed before `npm install` is run.
-
-```sh
-pkg install -y pkgconf vips
-```
-
-```sh
-cd /usr/ports/graphics/vips/ && make install clean
-```
-
-## Linux memory allocator
-
-The default memory allocator on most glibc-based Linux systems
-(e.g. Debian, Red Hat) is unsuitable for long-running, multi-threaded
-processes that involve lots of small memory allocations.
-
-For this reason, by default, sharp will limit the use of thread-based
-[concurrency](/api-utility#concurrency) when the glibc allocator is
-detected at runtime.
-
-To help avoid fragmentation and improve performance on these systems,
-the use of an alternative memory allocator such as
-[jemalloc](https://github.com/jemalloc/jemalloc) is recommended.
-
-Those using musl-based Linux (e.g. Alpine) and non-Linux systems are
-unaffected.
-
-## AWS Lambda
-
-The `node_modules` directory of the
-[deployment package](https://docs.aws.amazon.com/lambda/latest/dg/nodejs-package.html)
-must include binaries for either the linux-x64 or linux-arm64 platforms
-depending on the chosen architecture.
-
-When building your deployment package on a machine that differs from the target architecture,
-see the [cross-platform](#cross-platform) section to help decide which package manager is appropriate
-and how to configure it.
-
-Some package managers use symbolic links
-but AWS Lambda does not support these within deployment packages.
-
-To get the best performance select the largest memory available.
-A 1536 MB function provides ~12x more CPU time than a 128 MB function.
-
-When integrating with AWS API Gateway, ensure it is configured with the relevant
-[binary media types](https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-payload-encodings.html).
-
-## Bundlers
-
-### webpack
-
-Ensure sharp is excluded from bundling via the
-[externals](https://webpack.js.org/configuration/externals/)
-configuration.
-
-```js
-externals: {
-  'sharp': 'commonjs sharp'
-}
-```
-
-### esbuild
-
-Ensure sharp is excluded from bundling via the
-[external](https://esbuild.github.io/api/#external)
-configuration.
-
-```js
-buildSync({
-  entryPoints: ['app.js'],
-  bundle: true,
-  platform: 'node',
-  external: ['sharp'],
-})
-```
-
-```sh
-esbuild app.js --bundle --platform=node --external:sharp
-```
-
-For `serverless-esbuild`, ensure platform-specific binaries are installed
-via the `serverless.yml` configuration.
-
-```yaml
-custom:
-  esbuild:
-    external:
-      - sharp
-    packagerOptions:
-      scripts:
-        - npm install --os=linux --cpu=x64 sharp
-```
-
-### electron
-
-#### electron-builder
-
-Ensure `sharp` is unpacked from the ASAR archive file using the
-[asarUnpack](https://www.electron.build/app-builder-lib.interface.platformspecificbuildoptions#asarunpack)
-option.
-
-```json
-{
-  "build": {
-    "asar": true,
-    "asarUnpack": [
-      "**/node_modules/sharp/**/*",
-      "**/node_modules/@img/**/*"
-    ]
-  }
-}
-```
-
-#### electron-forge
-
-Ensure `sharp` is unpacked from the ASAR archive file using the
-[unpack](https://js.electronforge.io/interfaces/_electron_forge_maker_squirrel.InternalOptions.Options.html#asar)
-option.
-
-```json
-{
-  "packagerConfig": {
-    "asar": {
-      "unpack": "**/node_modules/{sharp,@img}/**/*"
-    }
-  }
-}
-```
-
-When using `electron-forge` with [Webpack](#webpack),
-you may also need to add
-[forge-externals-plugin](https://www.npmjs.com/package/@timfish/forge-externals-plugin).
-
-### vite
-
-Ensure `sharp` is excluded from bundling via the
-[build.rollupOptions](https://vitejs.dev/config/build-options.html)
-configuration.
-
-```js
-import { defineConfig } from 'vite';
-
-export default defineConfig({
-  build: {
-    rollupOptions: {
-      external: [
-        "sharp"
-      ]
-    }
-  }
-});
-```
-
-## TypeScript
-
-TypeScript definitions are published as part of
-the `sharp` package from v0.32.0.
-
-Previously these were available via the `@types/sharp` package,
-which is now deprecated.
-
-When using Typescript, please ensure `devDependencies` includes
-the `@types/node` package.
-
-## Fonts
-
-When creating text images or rendering SVG images that contain text elements,
-`fontconfig` is used to find the relevant fonts.
-
-On Windows and macOS systems, all system fonts are available for use.
-
-On macOS systems using Homebrew, you may need to set the
-`PANGOCAIRO_BACKEND` environment variable to a value of `fontconfig`
-to ensure it is used for font discovery instead of Core Text.
-
-On Linux systems, fonts that include the relevant
-[`fontconfig` configuration](https://www.freedesktop.org/software/fontconfig/fontconfig-user.html)
-when installed via package manager are available for use.
-
-If `fontconfig` configuration is not found, the following error will occur:
-```
-Fontconfig error: Cannot load default config file
-```
-
-In serverless environments where there is no control over font packages,
-use the `FONTCONFIG_PATH` environment variable to point to a custom location.
-
-Embedded SVG fonts are unsupported.
-
-## Known conflicts
-
-### Canvas and Windows
-
-If both `canvas` and `sharp` modules are used in the same Windows process, the following error may occur:
-```
-The specified procedure could not be found.

-title: Performance
---
-
-## Parallelism and concurrency
-
-Node.js uses a libuv-managed thread pool when processing asynchronous calls to native modules such as sharp.
-
-The maximum number of images that sharp can process in parallel is controlled by libuv's
-[`UV_THREADPOOL_SIZE`](https://nodejs.org/api/cli.html#uv_threadpool_sizesize)
-environment variable, which defaults to 4.
-
-When using more than 4 physical CPU cores, set this environment variable
-before the Node.js process starts to increase the thread pool size.
-
-```sh
-export UV_THREADPOOL_SIZE="$(lscpu -p | egrep -v "^#" | sort -u -t, -k 2,4 | wc -l)"
-```
-
-libvips uses a glib-managed thread pool to avoid the overhead of spawning new threads.
-
-The default number of threads used to concurrently process each image is the same as the number of CPU cores,
-except when using glibc-based Linux without jemalloc, where the default is `1` to help reduce memory fragmentation.
-
-Use [`sharp.concurrency()`](/api-utility/#concurrency) to manage the number of threads per image.
-
-To reduce memory fragmentation when using the default Linux glibc memory allocator, set the
-[`MALLOC_ARENA_MAX`](https://www.gnu.org/software/libc/manual/html_node/Memory-Allocation-Tunables.html)
-environment variable before the Node.js process starts to reduce the number of memory pools.
-
-```sh
-export MALLOC_ARENA_MAX="2"
-```
-
-## Benchmark
-
-A test to benchmark the performance of this module relative to alternatives.
-
-Greater libvips performance can be expected with caching enabled (default)
-and using 8+ core machines, especially those with larger L1/L2 CPU caches.
-
-The I/O limits of the relevant (de)compression library will generally determine maximum throughput.
-
-### Contenders
-
- [jimp](https://www.npmjs.com/package/jimp) v1.6.0 - Image processing in pure JavaScript.
- [imagemagick](https://www.npmjs.com/package/imagemagick) v0.1.3 - Supports filesystem only and "_has been unmaintained for a long time_".
- [gm](https://www.npmjs.com/package/gm) v1.25.1 - Fully featured wrapper around GraphicsMagick's `gm` command line utility, but "_has been sunset_".
- sharp v0.34.3 / libvips v8.17.0 - Caching within libvips disabled to ensure a fair comparison.
-

-/**
- * Constructor factory to create an instance of `sharp`, to which further methods are chained.
- *
- * JPEG, PNG, WebP, GIF, AVIF or TIFF format image data can be streamed out from this object.
- * When using Stream based output, derived attributes are available from the `info` event.
- *
- * Non-critical problems encountered during processing are emitted as `warning` events.
- *
- * Implements the [stream.Duplex](http://nodejs.org/api/stream.html#stream_class_stream_duplex) class.
- *
- * When loading more than one page/frame of an animated image,
- * these are combined as a vertically-stacked "toilet roll" image
- * where the overall height is the `pageHeight` multiplied by the number of `pages`.
- *
- * @constructs Sharp
- *
- * @emits Sharp#info
- * @emits Sharp#warning
- *
- * @example
- * sharp('input.jpg')
- *   .resize(300, 200)
- *   .toFile('output.jpg', function(err) {
- *     // output.jpg is a 300 pixels wide and 200 pixels high image
- *     // containing a scaled and cropped version of input.jpg
- *   });
- *
- * @example
- * // Read image data from remote URL,
- * // resize to 300 pixels wide,
- * // emit an 'info' event with calculated dimensions
- * // and finally write image data to writableStream
- * const { body } = fetch('https://...');
- * const readableStream = Readable.fromWeb(body);
- * const transformer = sharp()
- *   .resize(300)
- *   .on('info', ({ height }) => {
- *     console.log(`Image height is ${height}`);
- *   });
- * readableStream.pipe(transformer).pipe(writableStream);
- *
- * @example
- * // Create a blank 300x200 PNG image of semi-translucent red pixels
- * sharp({
- *   create: {
- *     width: 300,
- *     height: 200,
- *     channels: 4,
- *     background: { r: 255, g: 0, b: 0, alpha: 0.5 }
- *   }
- * })
- * .png()
- * .toBuffer()
- * .then( ... );
- *
- * @example
- * // Convert an animated GIF to an animated WebP
- * await sharp('in.gif', { animated: true }).toFile('out.webp');
- *
- * @example
- * // Read a raw array of pixels and save it to a png
- * const input = Uint8Array.from([255, 255, 255, 0, 0, 0]); // or Uint8ClampedArray
- * const image = sharp(input, {
- *   // because the input does not contain its dimensions or how many channels it has
- *   // we need to specify it in the constructor options
- *   raw: {
- *     width: 2,
- *     height: 1,
- *     channels: 3
- *   }
- * });
- * await image.toFile('my-two-pixels.png');
- *
- * @example
- * // Generate RGB Gaussian noise
- * await sharp({
- *   create: {
- *     width: 300,
- *     height: 200,
- *     channels: 3,
- *     noise: {
- *       type: 'gaussian',
- *       mean: 128,
- *       sigma: 30
- *     }
- *  }
- * }).toFile('noise.png');
- *
- * @example
- * // Generate an image from text
- * await sharp({
- *   text: {
- *     text: 'Hello, world!',
- *     width: 400, // max width
- *     height: 300 // max height
- *   }
- * }).toFile('text_bw.png');
- *
- * @example
- * // Generate an rgba image from text using pango markup and font
- * await sharp({
- *   text: {
- *     text: '<span foreground="red">Red!</span><span background="cyan">blue</span>',
- *     font: 'sans',
- *     rgba: true,
- *     dpi: 300
- *   }
- * }).toFile('text_rgba.png');
- *
- * @example
- * // Join four input images as a 2x2 grid with a 4 pixel gutter
- * const data = await sharp(
- *  [image1, image2, image3, image4],
- *  { join: { across: 2, shim: 4 } }
- * ).toBuffer();
- *
- * @example
- * // Generate a two-frame animated image from emoji
- * const images = ['😀', '😛'].map(text => ({
- *   text: { text, width: 64, height: 64, channels: 4, rgba: true }
- * }));
- * await sharp(images, { join: { animated: true } }).toFile('out.gif');
- *

-/**
- * Resize image to `width`, `height` or `width x height`.
- *
- * When both a `width` and `height` are provided, the possible methods by which the image should **fit** these are:
- * - `cover`: (default) Preserving aspect ratio, attempt to ensure the image covers both provided dimensions by cropping/clipping to fit.
- * - `contain`: Preserving aspect ratio, contain within both provided dimensions using "letterboxing" where necessary.
- * - `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.
- *
- * <img alt="Examples of various values for the fit property when resizing" width="100%" style="aspect-ratio: 998/243" src="/api-resize-fit.svg">
- *
- * 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 strategy-based approach initially 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 downsizing kernels are:
- * - `nearest`: Use [nearest neighbour interpolation](http://en.wikipedia.org/wiki/Nearest-neighbor_interpolation).
- * - `linear`: Use a [triangle filter](https://en.wikipedia.org/wiki/Triangular_function).
- * - `cubic`: Use a [Catmull-Rom spline](https://en.wikipedia.org/wiki/Centripetal_Catmull%E2%80%93Rom_spline).
- * - `mitchell`: Use a [Mitchell-Netravali spline](https://www.cs.utexas.edu/~fussell/courses/cs384g-fall2013/lectures/mitchell/Mitchell.pdf).
- * - `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).
- * - `mks2013`: Use a [Magic Kernel Sharp](https://johncostella.com/magic/mks.pdf) 2013 kernel, as adopted by Facebook.
- * - `mks2021`: Use a Magic Kernel Sharp 2021 kernel, with more accurate (reduced) sharpening than the 2013 version.
- *
- * When upsampling, these kernels map to `nearest`, `linear` and `cubic` interpolators.
- * Downsampling kernels without a matching upsampling interpolator map to `cubic`.
- *
- * Only one resize can occur per pipeline.
- * Previous calls to `resize` in the same pipeline will be ignored.
- *
- * @example
- * sharp(input)
- *   .resize({ width: 100 })
- *   .toBuffer()
- *   .then(data => {
- *     // 100 pixels wide, auto-scaled height
- *   });
- *
- * @example
- * sharp(input)
- *   .resize({ height: 100 })
- *   .toBuffer()
- *   .then(data => {
- *     // 100 pixels high, auto-scaled width
- *   });
- *
- * @example
- * sharp(input)
- *   .resize(200, 300, {
- *     kernel: sharp.kernel.nearest,
- *     fit: 'contain',
- *     position: 'right top',
- *     background: { r: 255, g: 255, b: 255, alpha: 0.5 }
- *   })
- *   .toFile('output.png')
- *   .then(() => {
- *     // output.png is a 200 pixels wide and 300 pixels high image
- *     // containing a nearest-neighbour scaled version
- *     // contained within the north-east corner of a semi-transparent white canvas
- *   });
- *
- * @example
- * const transformer = sharp()
- *   .resize({
- *     width: 200,
- *     height: 200,
- *     fit: sharp.fit.cover,
- *     position: sharp.strategy.entropy
- *   });
- * // Read image data from readableStream
- * // Write 200px square auto-cropped image data to writableStream
- * readableStream
- *   .pipe(transformer)
- *   .pipe(writableStream);
- *
- * @example
- * sharp(input)
- *   .resize(200, 200, {
- *     fit: sharp.fit.inside,
- *     withoutEnlargement: true
- *   })
- *   .toFormat('jpeg')
- *   .toBuffer()
- *   .then(function(outputBuffer) {
- *     // outputBuffer contains JPEG image data
- *     // no wider and no higher than 200 pixels
- *     // and no larger than the input image
- *   });
- *
- * @example
- * sharp(input)
- *   .resize(200, 200, {
- *     fit: sharp.fit.outside,
- *     withoutReduction: true
- *   })
- *   .toFormat('jpeg')
- *   .toBuffer()
- *   .then(function(outputBuffer) {
- *     // outputBuffer contains JPEG image data
- *     // of at least 200 pixels wide and 200 pixels high while maintaining aspect ratio
- *     // and no smaller than the input image
- *   });
- *
- * @example
- * const scaleByHalf = await sharp(input)
- *   .metadata()
- *   .then(({ width }) => sharp(input)
- *     .resize(Math.round(width * 0.5))
- *     .toBuffer()
