Backend Library: `Pillow `_
Plugin that wraps the the Pillow library. Pillow is a friendly fork of PIL
(Python Image Library) and supports reading and writing of common formats (jpg,
png, gif, tiff, ...). For, the complete list of features and supported formats
please refer to pillows official docs (see the Backend Library link).

Parses the given URI and creates a ndarray from it.
Parameters
----------
index : int
If the ImageResource contains multiple ndimages, and index is an
integer, select the index-th ndimage from among them and return it.
If index is an ellipsis (...), read all ndimages in the file and
stack them along a new batch dimension and return them. If index is
None, this plugin reads the first image of the file (index=0) unless
the image is a GIF or APNG, in which case all images are read
(index=...).
mode : str
Convert the image to the given mode before returning it. If None,
the mode will be left unchanged. Possible modes can be found at:
https://pillow.readthedocs.io/en/stable/handbook/concepts.html#modes
rotate : bool
If True and the image contains an EXIF orientation tag,
apply the orientation before returning the ndimage.
apply_gamma : bool
If True and the image contains metadata about gamma, apply gamma
correction to the image.
writable_output : bool
If True, ensure that the image is writable before returning it to
the user. This incurs a full copy of the pixel data if the data
served by pillow is read-only. Consequentially, setting this flag to
False improves performance for some images.
pilmode : str
Deprecated, use `mode` instead.
exifrotate : bool
Deprecated, use `rotate` instead.
as_gray : bool
Deprecated. Exists to raise a constructive error message.
Returns
-------
ndimage : ndarray
A numpy array containing the loaded image data
Notes
-----
If you read a paletted image (e.g. GIF) then the plugin will apply the
palette by default. Should you wish to read the palette indices of each
pixel use ``mode="P"``. The coresponding color pallete can be found in
the image's metadata using the ``palette`` key when metadata is
extracted using the ``exclude_applied=False`` kwarg. The latter is
needed, as palettes are applied by default and hence excluded by default
to keep metadata and pixel data consistent.
Nz,`pilmode` is deprecated. Use `mode` instead.z1`exifrotate` is deprecated. Use `rotate` instead.zThe keyword `as_gray` is no longer supported.Use `mode='F'` for a backward-compatible result, or `mode='L'` for an integer-valued result.GIF

Parameters
----------
mode : {str, None}
Convert the image to the given mode before returning it. If None,
the mode will be left unchanged. Possible modes can be found at:
https://pillow.readthedocs.io/en/stable/handbook/concepts.html#modes
rotate : {bool}
If set to ``True`` and the image contains an EXIF orientation tag,
apply the orientation before returning the ndimage.
apply_gamma : {bool}
If ``True`` and the image contains metadata about gamma, apply gamma
correction to the image.
writable_output : bool
If True, ensure that the image is writable before returning it to
the user. This incurs a full copy of the pixel data if the data
served by pillow is read-only. Consequentially, setting this flag to
False improves performance for some images.

Notes
-----
When writing batches of very narrow (2-4 pixels wide) gray images set
the ``mode`` explicitly to avoid the batch being identified as a colored
image.

Parameters
----------
index : {integer, None}
If the ImageResource contains multiple ndimages, and index is an
integer, select the index-th ndimage from among them and return its
metadata. If index is an ellipsis (...), read and return global
metadata. If index is None, this plugin reads metadata from the
first image of the file (index=0) unless the image is a GIF or APNG,
in which case global metadata is read (index=...).
exclude_applied : bool
If True, exclude metadata fields that are applied to the image while
reading. For example, if the binary data contains a rotation flag,
the image is rotated by default and the rotation flag is excluded
from the metadata to avoid confusion.
Returns
-------
metadata : dict
A dictionary of format-specific metadata.

Parameters
----------
index : int
If the ImageResource contains multiple ndimages, and index is an
integer, select the index-th ndimage from among them and return its
properties. If index is an ellipsis (...), read and return the
properties of all ndimages in the file stacked along a new batch
dimension. If index is None, this plugin reads and returns the
properties of the first image (index=0) unless the image is a GIF or
APNG, in which case it reads and returns the properties all images
(index=...).
Returns
-------
properties : ImageProperties
A dataclass filled with standardized image metadata.
Notes
-----
This does not decode pixel data and is fast for large images.
