8.0.0¶
Backwards Incompatible Changes¶
Python 3.5¶
Pillow has dropped support for Python 3.5, which reached end-of-life on 2020-09-13.
PyPy 7.1.x¶
Pillow has dropped support for PyPy3 7.1.1. PyPy3 7.2.0, released on 2019-10-14, is now the minimum compatible version.
im.offset¶
im.offset()
has been removed, call ImageChops.offset()
instead.
Image.fromstring, im.fromstring and im.tostring¶
Image.fromstring()
has been removed, callImage.frombytes()
instead.im.fromstring()
has been removed, callfrombytes()
instead.im.tostring()
has been removed, calltobytes()
instead.
ImageCms.CmsProfile attributes¶
Some attributes in PIL.ImageCms.CmsProfile
have been removed:

API Changes¶
ImageDraw.text: stroke_width¶
Fixed issue where passing stroke_width
with a non-zero value
to ImageDraw.text()
would cause the text to be offset by that amount.
ImageDraw.text: anchor¶
The anchor
parameter of ImageDraw.text()
has been implemented.
Use this parameter to change the position of text relative to the
specified xy
point. See Text anchors for details.
Add MIME type to PsdImagePlugin¶
“image/vnd.adobe.photoshop” is now registered as the
PsdImagePlugin.PsdImageFile
MIME type.
API Additions¶
Image.open: add formats parameter¶
Added a new formats
parameter to Image.open()
:
A list or tuple of formats to attempt to load the file in. This can be used to restrict the set of formats checked. Pass
None
to try all supported formats. You can print the set of available formats by runningpython3 -m PIL
or using thePIL.features.pilinfo()
function.
ImageOps.autocontrast: add mask parameter¶
ImageOps.autocontrast()
can now take a mask
parameter:
Histogram used in contrast operation is computed using pixels within the mask. If no mask is given the entire image is used for histogram computation.
ImageOps.autocontrast cutoffs¶
Previously, the cutoff
parameter of ImageOps.autocontrast()
could only
be a single number, used as the percent to cut off from the histogram on the low and
high ends.
Now, it can also be a tuple (low, high)
.
ImageDraw.regular_polygon¶
A new method ImageDraw.regular_polygon()
, draws a regular polygon of n_sides
, inscribed in a bounding_circle
.
For example draw.regular_polygon(((100, 100), 50), 5)
draws a pentagon centered at the point (100, 100)
with a polygon radius of 50
.
ImageDraw.text: embedded_color¶
The methods ImageDraw.text()
and ImageDraw.multiline_text()
now support fonts with embedded color data.
To render text with embedded color data, use the parameter embedded_color=True
.
Support for CBDT fonts requires FreeType 2.5 compiled with libpng. Support for SBIX fonts requires FreeType 2.5.1 compiled with libpng. Support for COLR fonts requires FreeType 2.10. SVG fonts are not yet supported.
ImageDraw.textlength¶
Two new methods ImageDraw.textlength()
and FreeTypeFont.getlength()
were added, returning the exact advance length of text with 1/64 pixel precision.
These can be used for word-wrapping or rendering text in parts.
ImageDraw.textbbox¶
Three new methods ImageDraw.textbbox()
, ImageDraw.multiline_textbbox()
,
and FreeTypeFont.getbbox()
return the bounding box of rendered text.
These functions accept an anchor
parameter, see Text anchors for details.
Other Changes¶
Improved ellipse-drawing algorithm¶
The ellipse-drawing algorithm has been changed from drawing a 360-sided polygon to one which resembles Bresenham’s algorithm for circles. It should be faster and produce smoother curves, especially for smaller ellipses.
ImageDraw.text and ImageDraw.multiline_text¶
Fixed multiple issues in methods ImageDraw.text()
and ImageDraw.multiline_text()
sometimes causing unexpected text alignment issues.
The align
parameter of ImageDraw.multiline_text()
now gives better results in some cases.
TrueType fonts with embedded bitmaps are now supported.
Added writing of subIFDs¶
When saving EXIF data, Pillow is now able to write subIFDs, such as the GPS IFD. This
should happen automatically when saving an image using the EXIF data that it was opened
with, such as in exif_transpose()
.
Previously, the code of the first tag of the subIFD was incorrectly written as the offset.
Error for large BMP files¶
Previously, if a BMP file was too large, an OSError
would be raised. Now,
DecompressionBombError
is used instead, as Pillow already uses for other formats.
Dark theme for docs¶
The https://pillow.readthedocs.io documentation will use a dark theme if the user has requested the system use one. Uses the prefers-color-scheme
CSS media query.
