@ -35,11 +35,12 @@ Image.fromarray mode parameter
.. deprecated:: 11.3.0
Using the ``mode`` parameter in :py:meth:`~PIL.Image.fromarray()` to change data types
has been deprecated. Since pixel values do not contain information about palettes or
color spaces, the parameter can still be used to place grayscale L mode data within a
P mode image, or read RGB data as YCbCr for example. If omitted, the mode will be
automatically determined from the object's shape and type.
Using the ``mode`` parameter in :py:meth:`~PIL.Image.fromarray()` was deprecated in
Pillow 11.3.0. In Pillow 12.0.0, this was partially reverted, and it is now only
deprecated when changing data types. Since pixel values do not contain information
about palettes or color spaces, the parameter can still be used to place grayscale L
mode data within a P mode image, or read RGB data as YCbCr for example. If omitted, the
mode will be automatically determined from the object's shape and type.
