Other changes

|
=============
|
|
|
|
Saving multipage images
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
There is now support for saving multipage images in the ``GIF`` and
|
|
``PDF`` formats. To enable this functionality, pass in ``save_all=True``
|
|
as a keyword argument to the save::
|
|
|
|
im.save('test.pdf', save_all=True)
|
|
|
|
TIFF ImageFileDirectory rewrite
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The TIFF ImageFileDirectory metadata code has been rewritten. Where
|
|
previously it returned a somewhat arbitrary set of values and tuples,
|
|
it now returns bare values where appropriate and tuples when the
|
|
metadata item is a sequence or collection.
|
|
|
|
The original metadata is still available in the TiffImage.tags, the
|
|
new values are available in the TiffImage.tags_v2 member. The old
|
|
structures will be deprecated at some point in the future. When
|
|
saving TIFF metadata, new code should use the
|
|
TiffImagePlugin.ImageFileDirectory_v2 class.
|
|
|
|
LibJpeg and Zlib are required by default
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The external dependencies on libjpeg and zlib are now required by default.
|
|
If the headers or libraries are not found, then installation will abort
|
|
with an error. This behaviour can be disabled with the ``--disable-libjpeg``
|
|
and ``--disable-zlib`` flags.
