Libimagequant support
|
|
=====================
|
|
|
|
There is now support for using libimagequant as a higher quality
|
|
quantization option in ``Image.quantize()`` on Unix-like
|
|
platforms. This support requires building Pillow from source against
|
|
libimagequant. We cannot distribute binaries due to licensing
|
|
differences.
|
|
|
|
New Setup.py options
|
|
====================
|
|
|
|
There are two new options to control the ``build_ext`` task in ``setup.py``:
|
|
|
|
* ``--debug`` dumps all of the directories and files that are
|
|
checked when searching for libraries or headers when building the
|
|
extensions.
|
|
* ``--disable-platform-guessing`` removes many of the directories
|
|
that are checked for libraries and headers for build systems or
|
|
cross compilers that specify that information in via environment
|
|
variables.
|
|
|
|
|
|
Image Metadata
|
|
==============
|
|
|
|
The return type for binary data in version 2 Exif and Tiff metadata
|
|
has been changed from a tuple of integers to bytes. This is a change
|
|
from the behavior since ``3.0.0``.
