+
+The typical use case for this high speed Node.js module
+is to convert large images in common formats to
+smaller, web-friendly JPEG, PNG, WebP, GIF and AVIF 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).
+
+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 running Node.js >= 14.15.0
+do not require any additional install or runtime dependencies.

+ * Rotate the output image by either an explicit angle
+ * or auto-orient based on the EXIF `Orientation` tag.
+ *
+ * If an angle is provided, it 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.
+ *
+ * If no angle is provided, it is determined from the EXIF data.
+ * Mirroring is supported and may infer the use of a flip operation.
+ *
+ * The use of `rotate` without an angle will remove the EXIF `Orientation` tag, if any.
+ *
+ * Only one rotation can occur per pipeline.
+ * Previous calls to `rotate` in the same pipeline will be ignored.
+ *
+ * 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)`.

+ * const pipeline = sharp()

+ *     // auto-rotated using EXIF Orientation tag
+ *     // info.width and info.height contain the dimensions of the resized image
+ *   });

+ * 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="https://cdn.jsdelivr.net/gh/lovell/sharp@main/docs/image/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 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).
+ * - `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).
+ *
+ * Only one resize can occur per pipeline.
+ * Previous calls to `resize` in the same pipeline will be ignored.

+///////////////////////////////////////////////////////////////////////////////
+// Internal implementation details
+///////////////////////////////////////////////////////////////////////////////
+//
+// There are two levels of interfaces used to access the AOM codec: the
+// aom_codec_iface and the aom_codec_ctx.
+//
+// 1. aom_codec_iface_t
+//    (Related files: aom/aom_codec.h, aom/src/aom_codec.c,
+//    aom/internal/aom_codec_internal.h, av1/av1_cx_iface.c,
+//    av1/av1_dx_iface.c)
+//
+// Used to initialize the codec context, which contains the configuration for
+// for modifying the encoder/decoder during run-time. See the other
+// documentation in this header file for more details. For the most part,
+// users will call helper functions, such as aom_codec_iface_name,
+// aom_codec_get_caps, etc., to interact with it.
+//
+// The main purpose of the aom_codec_iface_t is to provide a way to generate
+// a default codec config, find out what capabilities the implementation has,
+// and create an aom_codec_ctx_t (which is actually used to interact with the
+// codec).
+//
+// Note that the implementations for the AV1 algorithm are located in
+// av1/av1_cx_iface.c and av1/av1_dx_iface.c
+//
+//
+// 2. aom_codec_ctx_t
+//  (Related files: aom/aom_codec.h, av1/av1_cx_iface.c, av1/av1_dx_iface.c,
+//   aom/aomcx.h, aom/aomdx.h, aom/src/aom_encoder.c, aom/src/aom_decoder.c)
+//
+// The actual interface between user code and the codec. It stores the name
+// of the codec, a pointer back to the aom_codec_iface_t that initialized it,
+// initialization flags, a config for either encoder or the decoder, and a
+// pointer to internal data.
+//
+// The codec is configured / queried through calls to aom_codec_control,
+// which takes a control ID (listed in aomcx.h and aomdx.h) and a parameter.
+// In the case of "getter" control IDs, the parameter is modified to have
+// the requested value; in the case of "setter" control IDs, the codec's
+// configuration is changed based on the parameter. Note that a aom_codec_err_t
+// is returned, which indicates if the operation was successful or not.
+//
+// Note that for the encoder, the aom_codec_alg_priv_t points to the
+// the aom_codec_alg_priv structure in av1/av1_cx_iface.c, and for the decoder,
+// the struct in av1/av1_dx_iface.c. Variables such as AV1_COMP cpi are stored
+// here and also used in the core algorithm.
+//
+// At the end, aom_codec_destroy should be called for each initialized
+// aom_codec_ctx_t.

+ * This file describes the interface between an application and a

+ * algorithm's interface structure:
+ *     <pre>

+ *           aom_codec_dec_cfg_t cfg = { threads, 0, 0, 1 };
+ *           res = aom_codec_dec_init(&algo, &my_codec, &cfg, 0);
+ *       }
+ *     </pre>
+ *
+ * Once initialized, the instance is managed using other functions from
+ * the aom_codec_* family.

+ * Utility to match up hardlinks.
+ *
+ * The 'struct archive_entry_linkresolver' is a cache of archive entries
+ * for files with multiple links.  Here's how to use it:
+ *   1. Create a lookup object with archive_entry_linkresolver_new()
+ *   2. Tell it the archive format you're using.
+ *   3. Hand each archive_entry to archive_entry_linkify().
+ *      That function will return 0, 1, or 2 entries that should
+ *      be written.
+ *   4. Call archive_entry_linkify(resolver, NULL) until
+ *      no more entries are returned.
+ *   5. Call archive_entry_linkresolver_free(resolver) to free resources.
+ *
+ * The entries returned have their hardlink and size fields updated
+ * appropriately.  If an entry is passed in that does not refer to
+ * a file with multiple links, it is returned unchanged.  The intention
+ * is that you should be able to simply filter all entries through
+ * this machine.
+ *
+ * To make things more efficient, be sure that each entry has a valid
+ * nlinks value.  The hardlink cache uses this to track when all links
+ * have been found.  If the nlinks value is zero, it will keep every
+ * name in the cache indefinitely, which can use a lot of memory.
+ *
+ * Note that archive_entry_size() is reset to zero if the file
+ * body should not be written to the archive.  Pay attention!
+ */
+struct archive_entry_linkresolver;
+
+/*
+ * There are three different strategies for marking hardlinks.
+ * The descriptions below name them after the best-known
+ * formats that rely on each strategy:
+ *
+ * "Old cpio" is the simplest, it always returns any entry unmodified.
+ *    As far as I know, only cpio formats use this.  Old cpio archives
+ *    store every link with the full body; the onus is on the dearchiver
+ *    to detect and properly link the files as they are restored.
+ * "tar" is also pretty simple; it caches a copy the first time it sees
+ *    any link.  Subsequent appearances are modified to be hardlink
+ *    references to the first one without any body.  Used by all tar
+ *    formats, although the newest tar formats permit the "old cpio" strategy
+ *    as well.  This strategy is very simple for the dearchiver,
+ *    and reasonably straightforward for the archiver.
+ * "new cpio" is trickier.  It stores the body only with the last
+ *    occurrence.  The complication is that we might not
+ *    see every link to a particular file in a single session, so
+ *    there's no easy way to know when we've seen the last occurrence.
+ *    The solution here is to queue one link until we see the next.
+ *    At the end of the session, you can enumerate any remaining
+ *    entries by calling archive_entry_linkify(NULL) and store those
+ *    bodies.  If you have a file with three links l1, l2, and l3,
+ *    you'll get the following behavior if you see all three links:
+ *           linkify(l1) => NULL   (the resolver stores l1 internally)
+ *           linkify(l2) => l1     (resolver stores l2, you write l1)
+ *           linkify(l3) => l2, l3 (all links seen, you can write both).
+ *    If you only see l1 and l2, you'll get this behavior:
+ *           linkify(l1) => NULL
+ *           linkify(l2) => l1
+ *           linkify(NULL) => l2   (at end, you retrieve remaining links)
+ *    As the name suggests, this strategy is used by newer cpio variants.
+ *    It's noticeably more complex for the archiver, slightly more complex
+ *    for the dearchiver than the tar strategy, but makes it straightforward
+ *    to restore a file using any link by simply continuing to scan until
+ *    you see a link that is stored with a body.  In contrast, the tar
+ *    strategy requires you to rescan the archive from the beginning to
+ *    correctly extract an arbitrary link.

+   *   ```

+   *     #include FT_MULTIPLE_MASTERS_H
+   *     #include FT_GLYPH_H
+   *   ```
+   *

+   *
+   * @title:
+   *   Error Enumerations
+   *
+   * @abstract:
+   *   How to handle errors and error strings.
+   *
+   * @description:
+   *   The header file `fterrors.h` (which is automatically included by
+   *   `freetype.h`) defines the handling of FreeType's enumeration
+   *   constants.  It can also be used to generate error message strings
+   *   with a small macro trick explained below.
+   *
+   *   **Error Formats**
+   *
+   *   The configuration macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` can be
+   *   defined in `ftoption.h` in order to make the higher byte indicate the
+   *   module where the error has happened (this is not compatible with
+   *   standard builds of FreeType~2, however).  See the file `ftmoderr.h`
+   *   for more details.
+   *
+   *   **Error Message Strings**
+   *
+   *   Error definitions are set up with special macros that allow client
+   *   applications to build a table of error message strings.  The strings
+   *   are not included in a normal build of FreeType~2 to save space (most
+   *   client applications do not use them).
+   *
+   *   To do so, you have to define the following macros before including
+   *   this file.
+   *
+   *   ```
+   *     FT_ERROR_START_LIST
+   *   ```
+   *
+   *   This macro is called before anything else to define the start of the
+   *   error list.  It is followed by several `FT_ERROR_DEF` calls.
+   *
+   *   ```
+   *     FT_ERROR_DEF( e, v, s )
+   *   ```
+   *
+   *   This macro is called to define one single error.  'e' is the error
+   *   code identifier (e.g., `Invalid_Argument`), 'v' is the error's
+   *   numerical value, and 's' is the corresponding error string.
+   *
+   *   ```
+   *     FT_ERROR_END_LIST
+   *   ```
+   *
+   *   This macro ends the list.
+   *
+   *   Additionally, you have to undefine `FTERRORS_H_` before #including
+   *   this file.
+   *
+   *   Here is a simple example.
+   *
+   *   ```
+   *     #undef FTERRORS_H_
+   *     #define FT_ERRORDEF( e, v, s )  { e, s },
+   *     #define FT_ERROR_START_LIST     {
+   *     #define FT_ERROR_END_LIST       { 0, NULL } };
+   *
+   *     const struct
+   *     {
+   *       int          err_code;
+   *       const char*  err_msg;
+   *     } ft_errors[] =
+   *
+   *     #include <freetype/fterrors.h>
+   *   ```
+   *
+   *   An alternative to using an array is a switch statement.
+   *
+   *   ```
+   *     #undef FTERRORS_H_
+   *     #define FT_ERROR_START_LIST     switch ( error_code ) {
+   *     #define FT_ERRORDEF( e, v, s )    case v: return s;
+   *     #define FT_ERROR_END_LIST       }
+   *   ```
+   *
+   *   If you use `FT_CONFIG_OPTION_USE_MODULE_ERRORS`, `error_code` should
+   *   be replaced with `FT_ERROR_BASE(error_code)` in the last example.
+   */

+   *   @FT_LOAD_NO_SCALE, the resulting CBox is meaningless.  To get
+   *   reasonable values for the CBox it is necessary to load the glyph at a
+   *   large ppem value (so that the hinting instructions can properly shift
+   *   and scale the subglyphs), then extracting the CBox, which can be
+   *   eventually converted back to font units.
+   *
+   *   Note that the maximum coordinates are exclusive, which means that one
+   *   can compute the width and height of the glyph image (be it in integer
+   *   or 26.6 pixels) as:
+   *
+   *   ```
+   *     width  = bbox.xMax - bbox.xMin;
+   *     height = bbox.yMax - bbox.yMin;
+   *   ```
+   *
+   *   Note also that for 26.6 coordinates, if `bbox_mode` is set to
+   *   @FT_GLYPH_BBOX_GRIDFIT, the coordinates will also be grid-fitted,
+   *   which corresponds to:
+   *
+   *   ```
+   *     bbox.xMin = FLOOR(bbox.xMin);
+   *     bbox.yMin = FLOOR(bbox.yMin);
+   *     bbox.xMax = CEILING(bbox.xMax);
+   *     bbox.yMax = CEILING(bbox.yMax);
+   *   ```
+   *
+   *   To get the bbox in pixel coordinates, set `bbox_mode` to
+   *   @FT_GLYPH_BBOX_TRUNCATE.
+   *
+   *   To get the bbox in grid-fitted pixel coordinates, set `bbox_mode` to
+   *   @FT_GLYPH_BBOX_PIXELS.

+   *
+   *   destroy ::
+   *     A boolean that indicates that the original glyph image should be
