6.2.0

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

ImageGrab on multi-monitor Windows
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

An ``all_screens`` argument has been added to ``ImageGrab.grab``. If ``True``,
all monitors will be included in the created image.

API Changes
===========

Image.getexif
^^^^^^^^^^^^^

To allow for lazy loading of Exif data, ``Image.getexif()`` now returns a
shared instance of ``Image.Exif``.

Deprecations
^^^^^^^^^^^^

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.
