API Changes
|
|
===========
|
|
|
|
Deprecations
|
|
^^^^^^^^^^^^
|
|
|
|
These version constants have been deprecated. ``VERSION`` will be removed in
|
|
Pillow 6.0.0, and ``PILLOW_VERSION`` will be removed after that.
|
|
|
|
* ``PIL.VERSION`` (old PIL version 1.1.7)
|
|
* ``PIL.PILLOW_VERSION``
|
|
* ``PIL.Image.VERSION``
|
|
* ``PIL.Image.PILLOW_VERSION``
|
|
|
|
Use ``PIL.__version__`` instead.
|
|
|
|
API Additions
|
|
=============
|
|
|
|
3D color lookup tables
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Support for 3D color lookup table transformations has been added.
|
|
|
|
* https://en.wikipedia.org/wiki/3D_lookup_table
|
|
|
|
``Color3DLUT.generate`` transforms 3-channel pixels using the values of the
|
|
channels as coordinates in the 3D lookup table and interpolating the nearest
|
|
elements.
|
|
|
|
It allows you to apply almost any color transformation in constant time by
|
|
using pre-calculated decimated tables.
|
|
|
|
``Color3DLUT.transform()`` allows altering table values with a callback.
|
|
|
|
If NumPy is installed, the performance of argument conversion is dramatically
|
|
improved when a source table supports buffer interface (NumPy && arrays in
|
|
Python >= 3).
|
|
|
|
ImageColor.getrgb
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
Previously ``Image.rotate`` only supported HSL color strings. Now HSB and HSV
|
|
strings are also supported, as well as float values. For example,
|
|
``ImageColor.getrgb("hsv(180,100%,99.5%)")``.
|
|
|
|
ImageFile.get_format_mimetype
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
``ImageFile.get_format_mimetype`` has been added to return the MIME type of an
|
|
image file, where available. For example,
|
|
``Image.open("hopper.jpg").get_format_mimetype()`` returns ``"image/jpeg"``.
|
|
|
|
ImageFont.getsize_multiline
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
A new method to return the size of multiline text, for example
|
|
``font.getsize_multiline("ABC\nAaaa")``
|
|
|
|
Image.rotate
|
|
^^^^^^^^^^^^
|
|
|
|
A new named parameter, ``fillcolor``, has been added to ``Image.rotate``. This
|
|
color specifies the background color to use in the area outside the rotated
|
|
image. This parameter takes the same color specifications as used in
|
|
``Image.new``.
|
|
|
|
|
|
TGA file format
|
|
^^^^^^^^^^^^^^^
|
|
|
|
Pillow can now read and write LA data (in addition to L, P, RGB and RGBA), and
|
|
write RLE data (in addition to uncompressed).
|
|
|
|
Other Changes
|
|
=============
|
|
|
|
Support added for Python 3.7
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Pillow 5.2 supports Python 3.7.
|
|
|
|
Build macOS wheels with Xcode 6.4, supporting older macOS versions
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The macOS wheels for Pillow 5.1.0 were built with Xcode 9.2, meaning 10.12
|
|
Sierra was the lowest supported version.
|
|
|
|
Prior to Pillow 5.1.0, Xcode 8 was used, supporting El Capitan 10.11.
|
|
|
|
Instead, Pillow 5.2.0 is built with the oldest available Xcode 6.4 to support
|
|
at least 10.10 Yosemite.
|
|
|
|
Fix _i2f compilation with some GCC versions
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
For example, this allows compilation with GCC 4.8 on NetBSD.
|
|
|
|
Resolve confusion getting PIL / Pillow version string
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Re: "version constants deprecated" listed above, as user gnbl notes in #3082:
|
|
|
|
- it's confusing that PIL.VERSION returns the version string of the former PIL instead of Pillow's
|
|
- ReadTheDocs documentation is missing for some version branches (why is this, will it ever change, ...)
|
|
- it's confusing that PIL.version is a module and does not return the version information directly or hints on how to get it
|
|
- the package information header is essentially useless (placeholder, does not even mention Pillow, nor the version)
|
|
- PIL._version module documentation comment could explain how to access the version information
|
|
|
|
We have attempted to resolve these issues in #3083, #3090 and #3218.
