It's only useful if the caller has an IMAGING_CODEC_* error code, which are only produced by codec decode() methods and are automatically translated by ImageFile. Co-authored-by: Andrew Murray <radarhere@users.noreply.github.com>

Deprecations
|
|
============
|
|
|
|
ImageFile.raise_oserror
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
``ImageFile.raise_oserror()`` has been deprecated and will be removed in Pillow
|
|
12.0.0 (2025-10-15). The function is undocumented and is only useful for translating
|
|
error codes returned by a codec's ``decode()`` method, which ImageFile already does
|
|
automatically.

API Changes
|
|
===========
|
|
|
|
Zero or negative font size error
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
When creating a :py:class:`~PIL.ImageFont.FreeTypeFont` instance, either directly or
|
|
through :py:func:`~PIL.ImageFont.truetype`, if the font size is zero or less, a
|
|
:py:exc:`ValueError` will now be raised.
|
|
|
|
API Additions
|
|
=============
|
|
|
|
Added DdsImagePlugin enums
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
:py:class:`~PIL.DdsImagePlugin.DDSD`, :py:class:`~PIL.DdsImagePlugin.DDSCAPS`,
|
|
:py:class:`~PIL.DdsImagePlugin.DDSCAPS2`, :py:class:`~PIL.DdsImagePlugin.DDPF`,
|
|
:py:class:`~PIL.DdsImagePlugin.DXGI_FORMAT` and :py:class:`~PIL.DdsImagePlugin.D3DFMT`
|
|
enums have been added to :py:class:`PIL.DdsImagePlugin`.
|
|
|
|
JPEG restart marker interval
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
When saving JPEG files, ``restart_marker_blocks`` and ``restart_marker_rows`` can now
|
|
be used to emit restart markers whenever the specified number of MCU blocks or rows
|
|
have been produced.
|
|
|
|
JPEG tables-only streamtype
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
When saving JPEG files, ``streamtype`` can now be set to 1, for tables-only. This will
|
|
output only the quantization and Huffman tables for the image.
|
|
|
|
Security

Other Changes
|
|
=============
|
|
|
|
Added DDS BC4U and DX10 BC1 and BC4 reading
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Support has been added to read the BC4U format of DDS images.
|
|
|
|
Support has also been added to read DX10 BC1 and BC4, whether UNORM or
|
|
TYPELESS.
|
|
|
|
Optimized ImageStat.Stat count and extrema
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Calculating the :py:attr:`~PIL.ImageStat.Stat.count` and
|
|
:py:attr:`~PIL.ImageStat.Stat.extrema` statistics is now faster. After the
|
|
histogram is created in ``st = ImageStat.Stat(im)``, ``st.count`` is 3x as fast
|
|
on average and ``st.extrema`` is 12x as fast on average.
|
|
|
|
Encoder errors now report error detail as string
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
:py:exc:`OSError` exceptions from image encoders now include a textual description of
|
|
the error instead of a numeric error code.
