API Changes
|
|
===========
|
|
|
|
Changed WebP default "method" value when saving
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Previously, it was 0, for the best speed. The default has now been changed to 4, to
|
|
match WebP's default, for higher quality with still some speed optimisation.
|
|
|
|
Default resampling filter for special image modes
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Pillow 7.0 changed the default resampling filter to ``Image.BICUBIC``. However, as this
|
|
is not supported yet for images with a custom number of bits, the default filter for
|
|
those modes has been reverted to ``Image.NEAREST``.
|
|
|
|
ImageMorph incorrect mode errors
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
For ``apply()``, ``match()`` and ``get_on_pixels()``, if the image mode is not L, an
|
|
:py:exc:`Exception` was thrown. This has now been changed to a :py:exc:`ValueError`.
|
|
|
|
API Additions
|
|
=============
|
|
|
|
ImageOps.contain
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
Returns a resized version of the image, set to the maximum width and height within
|
|
``size``, while maintaining the original aspect ratio.
|
|
|
|
To compare it to other ImageOps methods:
|
|
|
|
- :py:meth:`~PIL.ImageOps.fit` expands an image until is fills ``size``, cropping the
|
|
parts of the image that do not fit.
|
|
- :py:meth:`~PIL.ImageOps.pad` expands an image to fill ``size``, without cropping, but
|
|
instead filling the extra space with ``color``.
|
|
- :py:meth:`~PIL.ImageOps.contain` is similar to :py:meth:`~PIL.ImageOps.pad`, but it
|
|
does not fill the extra space. Instead, the original aspect ratio is maintained. So
|
|
unlike the other two methods, it is not guaranteed to return an image of ``size``.
