8.3.1

Other Changes

Fixed regression converting to NumPy arrays

This fixes a regression introduced in 8.3.0 when converting an image to a NumPy array with a dtype argument.

>>> from PIL import Image
>>> import numpy
>>> im = Image.new("RGB", (100, 100))
>>> numpy.array(im, dtype=numpy.float64)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: __array__() takes 1 positional argument but 2 were given
>>>

Catch OSError when checking if destination is sys.stdout

In 8.3.0, a check to see if the destination was sys.stdout when saving an image was updated. This lead to an :pyOSError being raised if the environment restricted access.

The :pyOSError is now silently caught.

Fixed removing orientation in ImageOps.exif_transpose

In 8.3.0, :py~PIL.ImageOps.exif_transpose was changed to ensure that the original image EXIF data was not modified, and the orientation was only removed from the modified copy.

However, for certain images the orientation was already missing from the modified image, leading to a :pyKeyError.

This error has been resolved, and the copying of metadata to the modified image improved.
