6.0.0

Backwards Incompatible Changes

Python 3.4 dropped

Python 3.4 is EOL since 2019-03-16 and no longer supported. We will not be creating binaries, testing, or retaining compatibility with this version. The final version of Pillow for Python 3.4 is 5.4.1.

Removed deprecated PIL.OleFileIO

PIL.OleFileIO was removed as a vendored file and in Pillow 4.0.0 (2017-01) in favour of the upstream olefile Python package, and replaced with an ImportError. The deprecated file has now been removed from Pillow. If needed, install from PyPI (eg. pip install olefile).

Removed deprecated ImageOps functions

Several undocumented functions in ImageOps were deprecated in Pillow 4.3.0 (2017-10) and have now been removed: gaussian_blur, gblur, unsharp_mask, usm and box_blur. Use the equivalent operations in ImageFilter instead.

Removed deprecated VERSION

VERSION (the old PIL version, always 1.1.7) has been removed. Use __version__ instead.

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.x the last series to support Python 2.

PyQt4 and PySide

Qt 4 reached end-of-life on 2015-12-19. Its Python bindings are also EOL: PyQt4 since 2018-08-31 and PySide since 2015-10-14.

Support for PyQt4 and PySide has been deprecated from ImageQt and will be removed in a future version. Please upgrade to PyQt5 or PySide2.

API Additions

DIB file format

Pillow now supports reading and writing the Device Independent Bitmap file format.

Image.quantize

The dither option is now a customisable parameter (was previously hardcoded to 1). This parameter takes the same values used in Image.convert.

New language parameter

These text-rendering functions now accept a language parameter to request language-specific glyphs and ligatures from the font:

  • ImageDraw.ImageDraw.multiline_text()
  • ImageDraw.ImageDraw.multiline_textsize()
  • ImageDraw.ImageDraw.text()
  • ImageDraw.ImageDraw.textsize()
  • ImageFont.ImageFont.getmask()
  • ImageFont.ImageFont.getsize_multiline()
  • ImageFont.ImageFont.getsize()

PNG EXIF data

EXIF data can now be read from and saved to PNG images. However, unlike other image formats, EXIF data is not guaranteed to have been read until load() has been called.

Other Changes

Reading new DDS image format

Pillow can now read uncompressed RGB data from DDS images.

Reading TIFF with old-style JPEG compression

Added support reading TIFF files with old-style JPEG compression through LibTIFF. All YCbCr TIFF images are now always read as RGB.
