API Additions
=============
Text stroking
^^^^^^^^^^^^^
``stroke_width`` and ``stroke_fill`` arguments have been added to text drawing
operations. They allow text to be outlined, setting the width of the stroke and
and the color respectively. If not provided, ``stroke_fill`` will default to
the ``fill`` parameter.
.. code-block:: python
from PIL import Image, ImageDraw, ImageFont
font = ImageFont.truetype("Tests/fonts/FreeMono.ttf", 40)
font.getsize_multiline("A", stroke_width=2)
font.getsize("ABC\nAaaa", stroke_width=2)
im = Image.new("RGB", (100, 100))
draw = ImageDraw.Draw(im)
draw.textsize("A", font, stroke_width=2)
draw.multiline_textsize("ABC\nAaaa", font, stroke_width=2)
draw.text((10, 10), "A", "#f00", font, stroke_width=2, stroke_fill="#0f0")
draw.multiline_text((10, 10), "A\nB", "#f00", font,
stroke_width=2, stroke_fill="#0f0")
For example,
.. code-block:: python
from PIL import Image, ImageDraw, ImageFont
im = Image.new("RGB", (120, 130))
draw = ImageDraw.Draw(im)
font = ImageFont.truetype("Tests/fonts/FreeMono.ttf", 120)
draw.text((10, 10), "A", "#f00", font, stroke_width=2, stroke_fill="#0f0")
creates the following image:
.. image:: ../../Tests/images/imagedraw_stroke_different.png
API Changes
===========
Image.getexif
^^^^^^^^^^^^^
To allow for lazy loading of Exif data, ``Image.getexif()`` now returns a
shared instance of ``Image.Exif``.
Deprecations
^^^^^^^^^^^^
Python 2.7
~~~~~~~~~~
Python 2.7 reaches end-of-life on 2020-01-01.
Pillow 7.0.0 will be released on 2020-01-01 and will drop support for Python
2.7, making Pillow 6.2.x the last release series to support Python 2.
Image.frombuffer
~~~~~~~~~~~~~~~~
There has been a longstanding warning that the defaults of ``Image.frombuffer``
may change in the future for the "raw" decoder. The change will now take place
in Pillow 7.0.
Other Changes
=============
Removed bdist_wininst .exe installers
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.exe installers fell out of favour with PEP 527, and will be deprecated in
Python 3.8. Pillow will no longer be distributing them. Wheels should be used
instead.
Flags for libwebp in wheels
^^^^^^^^^^^^^^^^^^^^^^^^^^^
When building libwebp for inclusion in wheels, Pillow now adds the -O3 and
-DNDEBUG CFLAGS. These flags would be used by default if building libwebp
without debugging, and using them fixes a significant decrease in speed when
a wheel-installed copy of Pillow performs libwebp operations.

This function loads a font object from the given file or file-like
object, and creates a font object for a font of the given size.
Pillow uses FreeType to open font files. If you are opening many fonts
simultaneously on Windows, be aware that Windows limits the number of files
that can be open in C at once to 512. If you approach that limit, an
``OSError`` may be thrown, reporting that FreeType "cannot open resource".
This function requires the _imagingft service.
:param font: A filename or file-like object containing a TrueType font.
Under Windows, if the file is not found in this filename,
the loader also looks in Windows :file:`fonts/` directory.
If the file is not found in this filename, the loader may also
search in other directories, such as the :file:`fonts/`
directory on Windows or :file:`/Library/Fonts/`,
:file:`/System/Library/Fonts/` and :file:`~/Library/Fonts/` on
macOS.
:param size: The requested size, in points.
:param index: Which font face to load (default is first available face).
:param encoding: Which font encoding to use (default is Unicode). Common
encodings are "unic" (Unicode), "symb" (Microsoft
Symbol), "ADOB" (Adobe Standard), "ADBE" (Adobe Expert),
and "armn" (Apple Roman). See the FreeType documentation
for more information.
:param encoding: Which font encoding to use (default is Unicode). Possible
encodings include (see the FreeType documentation for more
information):
* "unic" (Unicode)
* "symb" (Microsoft Symbol)
* "ADOB" (Adobe Standard)
* "ADBE" (Adobe Expert)
* "ADBC" (Adobe Custom)
* "armn" (Apple Roman)
* "sjis" (Shift JIS)
* "gb " (PRC)
* "big5"
* "wans" (Extended Wansung)
* "joha" (Johab)
* "lat1" (Latin-1)
This specifies the character set to use. It does not alter the
encoding of any text provided in subsequent operations.
:param layout_engine: Which layout engine to use, if available:
`ImageFont.LAYOUT_BASIC` or `ImageFont.LAYOUT_RAQM`.
:return: A font object.
