Replaced TiffImagePlugin DEBUG with logging ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TiffImagePlugin.DEBUG = True has been a way to print various debugging
information when interacting with TIFF images. This has now been removed
in favour of Python's logging module, already used in other places in the
Pillow source code.
Corrected default offset when writing EXIF data ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Previously, the default offset argument for
:py:meth:~PIL.Image.Exif.tobytes was 0, which did not include the magic
header. It is now 8.
Moved to ImageFileDirectory_v2 in Image.Exif ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Moved from the legacy :py:class:PIL.TiffImagePlugin.ImageFileDirectory_v1 to
:py:class:PIL.TiffImagePlugin.ImageFileDirectory_v2 in
:py:class:PIL.Image.Exif. This means that Exif RATIONALs and SIGNED_RATIONALs
are now read as :py:class:PIL.TiffImagePlugin.IFDRational, instead of as a
tuple with a numerator and a denominator.
TIFF BYTE tags format ^^^^^^^^^^^^^^^^^^^^^
TIFF BYTE tags were previously read as a tuple containing a bytestring. They are now read as just a single bytestring.
Deprecations ^^^^^^^^^^^^
Image.show command parameter
The ``command`` parameter was deprecated and will be removed in a future release.
Use a subclass of :py:class:`PIL.ImageShow.Viewer` instead.
Image._showxv
~~~~~~~~~~~~~
``Image._showxv`` has been deprecated. Use :py:meth:`~PIL.Image.Image.show`
instead. If custom behaviour is required, use :py:meth:`~PIL.ImageShow.register` to add
a custom :py:class:`~PIL.ImageShow.Viewer` class.
ImageFile.raise_ioerror
~~~~~~~~~~~~~~~~~~~~~~~
:py:exc:`IOError` was merged into :py:exc:`OSError` in Python 3.3. So, ``ImageFile.raise_ioerror``
is now deprecated and will be removed in a future release. Use
``ImageFile.raise_oserror`` instead.
