Deprecations
|
|
============
|
|
|
|
ExifTags.IFD.Makernote
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
``ExifTags.IFD.Makernote`` has been deprecated. Instead, use
|
|
``ExifTags.IFD.MakerNote``.
|
|
|
|
API Changes
|
|
===========
|
|
|
|
Writing XMP bytes to JPEG and MPO
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Pillow 11.0.0 added writing XMP data to JPEG and MPO images::
|
|
|
|
im.info["xmp"] = b"test"
|
|
im.save("out.jpg")
|
|
|
|
However, this meant that XMP data was automatically kept from an opened image,
|
|
which is inconsistent with the rest of Pillow's behaviour. This functionality
|
|
has been removed. To write XMP data, the ``xmp`` argument can still be used for
|
|
JPEG files::
|
|
|
|
im.save("out.jpg", xmp=b"test")
|
|
|
|
To save XMP data to the second frame of an MPO image, ``encoderinfo`` can now
|
|
be used::
|
|
|
|
second_im.encoderinfo = {"xmp": b"test"}
|
|
im.save("out.mpo", save_all=True, append_images=[second_im])
|
|
|
|
API Additions
|
|
=============
|
|
|
|
Check for zlib-ng
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
You can check if Pillow has been built against the zlib-ng version of the
|
|
zlib library, and what version of zlib-ng is being used::
|
|
|
|
from PIL import features
|
|
features.check_feature("zlib_ng") # True or False
|
|
features.version_feature("zlib_ng") # "2.2.2" for example, or None
|
|
|
|
Saving TIFF as BigTIFF
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
TIFF images can now be saved as BigTIFF using a ``big_tiff`` argument::
|
|
|
|
im.save("out.tiff", big_tiff=True)
|
|
|
|
Other Changes
|
|
=============
|
|
|
|
Reading JPEG 2000 comments
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
When opening a JPEG 2000 image, the comment may now be read into
|
|
:py:attr:`~PIL.Image.Image.info` for J2K images, not just JP2 images.
|
|
|
|
Saving JPEG 2000 CMYK images
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
With OpenJPEG 2.5.3 or later, Pillow can now save CMYK images as JPEG 2000 files.
|
|
|
|
Minimum C version
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
C99 is now the minimum version of C required to compile Pillow from source.
|
|
|
|
zlib-ng in wheels
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
Wheels are now built against zlib-ng for improved speed. In tests, saving a PNG
|
|
was found to be more than twice as fast at higher compression levels.
