API Changes
|
|
===========
|
|
|
|
Setting image mode
|
|
^^^^^^^^^^^^^^^^^^
|
|
|
|
If you attempt to set the mode of an image directly, e.g.
|
|
``im.mode = "RGBA"``, you will now receive an :py:exc:`AttributeError`. This is
|
|
not about removing existing functionality, but instead about raising an
|
|
explicit error to prevent later consequences. The ``convert`` method is the
|
|
correct way to change an image's mode.
|
|
|
|
Accept a list in getpixel()
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
:py:meth:`~PIL.Image.Image.getpixel` now accepts a list of coordinates, as well
|
|
as a tuple. ::
|
|
|
|
from PIL import Image
|
|
im = Image.new("RGB", (1, 1))
|
|
im.getpixel((0, 0))
|
|
im.getpixel([0, 0])
|
|
|
|
BoxBlur and GaussianBlur allow for different x and y radii
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
:py:class:`~PIL.ImageFilter.BoxBlur` and
|
|
:py:class:`~PIL.ImageFilter.GaussianBlur` now allow a sequence of x and y radii
|
|
to be specified, rather than a single number for both dimensions. ::
|
|
|
|
from PIL import ImageFilter
|
|
ImageFilter.BoxBlur((2, 5))
|
|
ImageFilter.GaussianBlur((2, 5))
|
|
|
|
API Additions
|
|
=============
|
|
|
|
EpsImagePlugin.gs_binary
|
|
^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
``EpsImagePlugin.gs_windows_binary`` stores the name of the Ghostscript
|
|
executable on Windows. ``EpsImagePlugin.gs_binary`` has now been added for all
|
|
platforms, and can be used to customise the name of the executable, or disable
|
|
use entirely through ``EpsImagePlugin.gs_binary = False``.
|
|
|
|
has_transparency_data
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Images now have :py:attr:`~PIL.Image.Image.has_transparency_data` to indicate
|
|
whether the image has transparency data, whether in the form of an alpha
|
|
channel, a palette with an alpha channel, or a "transparency" key in the
|
|
:py:attr:`~PIL.Image.Image.info` dictionary.
|
|
|
|
Even if this attribute is true, the image might still appear solid, if all of
|
|
the values shown within are opaque.
|
|
|
|
ImageOps.cover
|
|
^^^^^^^^^^^^^^
|
|
|
|
Returns a resized version of the image, so that the requested size is covered,
|
|
while maintaining the original aspect ratio.
|
|
|
|
See :ref:`relative-resize` for a comparison between this and similar ``ImageOps``
|
|
methods.
|
|
|
|
size and font_size arguments when using default font
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Pillow has had a "better than nothing" default font, which can only be drawn at
|
|
one font size. Now, if FreeType support is available, a version of
|
|
`Aileron Regular <https://dotcolon.net/font/aileron>`_ is loaded, which can be
|
|
drawn at chosen font sizes.
|
|
|
|
The following ``size`` and ``font_size`` arguments can now be used to specify a
|
|
font size for this new builtin font::
|
|
|
|
ImageFont.load_default(size=24)
|
|
draw.text((0, 0), "test", font_size=24)
|
|
draw.textlength((0, 0), "test", font_size=24)
|
|
draw.textbbox((0, 0), "test", font_size=24)
|
|
draw.multiline_text((0, 0), "test", font_size=24)
|
|
draw.multiline_textbbox((0, 0), "test", font_size=24)
|
|
|
|
Other Changes
|
|
=============
|
|
|
|
Python 3.12
|
|
^^^^^^^^^^^
|
|
|
|
Pillow 10.0.0 had wheels built against Python 3.12 beta, available as a preview to help
|
|
others prepare for 3.12, and to ensure Pillow could be used immediately at the release
|
|
of 3.12.0 final (2023-10-02, :pep:`693`).
|
|
|
|
Pillow 10.1.0 now officially supports Python 3.12.
|
|
|
|
Added support for DDS BC5U and 8-bit color indexed images
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Support has been added to read BC5U DDS files as RGB images, and
|
|
PALETTEINDEXED8 DDS files as P mode images.
|
|
|
|
Support reading signed 8-bit YCbCr TIFF images
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
TIFF images with unsigned integer data, 8 bits per sample and a photometric
|
|
interpretation of YCbCr can now be read.
|
