had to add a typestub for PIL due to https://github.com/microsoft/pyright/issues/7832 We should remove it if that is either fixed or, if I fail to convince Eric, after the relevant type information is added to Pillow [no changelog]

Returns a converted copy of this image. For the "P" mode, this

This supports all possible conversions between "L", "RGB" and "CMYK". The

``matrix`` argument only supports "L" and "RGB".

L = R * 299/1000 + G * 587/1000 + B * 114/1000

|
|
The default method of converting a grayscale ("L") or "RGB"

image into a bilevel (mode "1") image uses Floyd-Steinberg
|
|
dither to approximate the original image luminosity levels. If
|
|
dither is ``None``, all values larger than 127 are set to 255 (white),
|
|
all other values to 0 (black). To use other thresholds, use the
|
|
:py:meth:`~PIL.Image.Image.point` method.
|
|
|
|
When converting from "RGBA" to "P" without a ``matrix`` argument,
|
|
this passes the operation to :py:meth:`~PIL.Image.Image.quantize`,
|
|
and ``dither`` and ``palette`` are ignored.
|

When converting from "PA", if an "RGBA" palette is present, the alpha

channel from the image will be used instead of the values from the palette.

|
Instead of an image, the source can be a integer or tuple
|
|
containing pixel values. The method then fills the region
|
|
with the given color. When creating RGB images, you can
|
|
also use color strings as supported by the ImageColor module.
|
|
|
|
If a mask is given, this method updates only the regions
|
|
indicated by the mask. You can use either "1", "L", "LA", "RGBA"
|
|
or "RGBa" images (if present, the alpha band is used as mask).
|
|
Where the mask is 255, the given image is copied as is. Where
|
|
the mask is 0, the current value is preserved. Intermediate
|
|
values will mix the two images together, including their alpha
|
|
channels if they have them.
|
|
|
|
See :py:meth:`~PIL.Image.Image.alpha_composite` if you want to
|
|
combine images with respect to their alpha channels.

If a 2-tuple is used instead, it's treated as the upper left
|
|
corner. If omitted or None, the source is pasted into the
|
|
upper left corner.
|
|
|
|
If an image is given as the second argument and there is no
|
|
third, the box defaults to (0, 0), and the second argument
|
|
is interpreted as a mask image.

|

Creates an image memory referencing pixel data in a byte buffer.
|
|
|
|
This function is similar to :py:func:`~PIL.Image.frombytes`, but uses data
|
|
in the byte buffer, where possible. This means that changes to the
|
|
original buffer object are reflected in this image). Not all modes can

share memory; supported modes include "L", "RGBX", "RGBA", and "CMYK".

The default parameters used for the "raw" decoder differs from that used for

:py:func:`~PIL.Image.frombytes`. This is a bug, and will probably be fixed in a

future release. The current release issues a warning if you do this; to disable
|

the warning, you should provide the full set of parameters. See below for details.

Creates an image memory from an object exporting the array interface

|
|
a = np.zeros((5, 5))

If ``obj`` is not contiguous, then the ``tobytes`` method is called

and :py:func:`~PIL.Image.frombuffer` is used.
|
|
|
|
In the case of NumPy, be aware that Pillow modes do not always correspond
|

to NumPy dtypes. Pillow modes only offer 1-bit pixels, 8-bit pixels,
|
|
32-bit signed integer pixels, and 32-bit floating point pixels.
|
|

Pillow images can also be converted to arrays::
|

from PIL import Image
|
|
import numpy as np
|
|
im = Image.open("hopper.jpg")
|
|
a = np.asarray(im)
|

|
When converting Pillow images to arrays however, only pixel values are

|
transferred. This means that P and PA mode images will lose their palette.

|
:param mode: Optional mode to use when reading ``obj``. Will be determined from

change how the data is read::
