Added Complex Text Rendering
|
|
============================
|
|
|
|
Pillow now supports complex text rendering for scripts requiring glyph
|
|
composition and bidirectional flow. This optional feature adds three
|
|
dependencies: harfbuzz, fribidi, and raqm. See the `install
|
|
documentation <../installation.html>`_ for further details. This feature is
|
|
tested and works on Unix and Mac, but has not yet been built on Windows
|
|
platforms.
|
|
|
|
New Optional Parameters
|
|
=======================
|
|
|
|
* :py:meth:`PIL.ImageDraw.floodfill` has a new optional parameter:
|
|
threshold. This specifies a tolerance for the color to replace with
|
|
the flood fill.
|
|
|
|
* The TIFF and PDF image writers now support the ``append_images``
|
|
optional parameter for specifying additional images to create
|
|
multipage outputs.
|
|
|
|
New DecompressionBomb Warning
|
|
=============================
|
|
|
|
:py:meth:`PIL.Image.Image.crop` now may raise a DecompressionBomb
|
|
warning if the crop region enlarges the image over the threshold
|
|
specified by :py:data:`PIL.Image.MAX_PIXELS`.
|
|
|
|
Removed Deprecated Items
|
|
========================
|
|
|
|
Several deprecated items have been removed.
|
|
|
|
* The methods :py:meth:`PIL.ImageWin.Dib.fromstring`,
|
|
:py:meth:`PIL.ImageWin.Dib.tostring` and
|
|
:py:meth:`PIL.TiffImagePlugin.ImageFileDirectory_v2.as_dict` have
|
|
been removed.
|
|
|
|
* Before Pillow 4.2.0, attempting to save an RGBA image as JPEG would
|
|
discard the alpha channel. From Pillow 3.4.0, a deprecation warning
|
|
was shown. From Pillow 4.2.0, the deprecation warning is removed and
|
|
an :py:exc:`IOError` is raised.
|
|
|
|
Removed Core Image Function
|
|
===========================
|
|
|
|
The unused function ``Image.core.new_array`` was removed. This is an
|
|
internal function that should not have been used by user code, but it
|
|
was accessible from the python layer.
