ImageCms constants and versions() function

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
A number of constants and a function in :py:mod:`.ImageCms` have been deprecated.
|
|
This includes a table of flags based on LittleCMS version 1 which has been replaced
|
|
with a new class :py:class:`.ImageCms.Flags` based on LittleCMS 2 flags.

API Changes
|
|
===========
|
|
|
|
Added alpha_quality argument when saving WebP images
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
When saving WebP images, an ``alpha_quality`` argument can be passed to the encoder. It
|
|
is an integer value between 0 to 100, where values other than 100 will provide lossy
|
|
compression.
|
|
|
|
Negative kmeans error
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
When calling :py:meth:`~PIL.Image.Image.quantize`, a negative ``kmeans`` will now
|
|
raise a :py:exc:`ValueError`, unless a palette is supplied to make the value redundant.
|
|
|
|
Negative P1-P3 PPM value error
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
If a P1-P3 PPM image contains a negative value, a :py:exc:`ValueError` will now be
|
|
raised.
|
|
|
|
API Additions
|
|
=============
|
|
|
|
Added PerspectiveTransform
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
:py:class:`~PIL.ImageTransform.PerspectiveTransform` has been added, meaning
|
|
that all of the :py:data:`~PIL.Image.Transform` values now have a corresponding
|
|
subclass of :py:class:`~PIL.ImageTransform.Transform`.
|
|
|
|
Other Changes
|
|
=============
|
|
|
|
Portable FloatMap (PFM) images
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Support has been added for reading and writing grayscale (Pf format)
|
|
Portable FloatMap (PFM) files containing ``F`` data.
|
|
|
|
Release GIL when fetching WebP frames
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Python's Global Interpreter Lock is now released when fetching WebP frames from
|
|
the libwebp decoder.
