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.

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,

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:


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


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


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.


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.
