API Changes
|
|
===========
|
|
|
|
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.
|
