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. python3 -m 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.

API Changes

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.

MIME type improvements

Previously, all JPEG2000 images had the MIME type “image/jpx”. This has now been corrected. After the file format drivers have been loaded, Image.MIME["JPEG2000"] will return “image/jp2”. ImageFile.get_format_mimetype will return “image/jpx” if a JPX profile is present, or “image/jp2” otherwise.

Previously, all SGI images had the MIME type “image/rgb”. This has now been corrected. After the file format drivers have been loaded, Image.MIME["SGI"] will return “image/sgi”. ImageFile.get_format_mimetype will return “image/rgb” if RGB image data is present, or “image/sgi” otherwise.

MIME types have been added to the PPM format. After the file format drivers have been loaded, Image.MIME["PPM"] will now return the generic “image/x-portable-anymap”. ImageFile.get_format_mimetype will return a MIME type specific to the color type.

The TGA, PCX and ICO formats also now have MIME types: “image/x-tga”, “image/x-pcx” and “image/x-icon” respectively.

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 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()

Added EXIF class

getexif() has been added, which returns an Exif instance. Values can be retrieved and set like a dictionary. When saving JPEG, PNG or WEBP, the instance can be passed as an exif argument to include any changes in the output image.

Added ImageOps.exif_transpose

exif_transpose() returns a copy of an image, transposed according to its EXIF Orientation tag.

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 be present in info 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.

TIFF compression codecs

Support has been added for the LZMA, Zstd and WebP TIFF compression codecs.

Improved support for transposing I;16 images

I;16, I;16L and I;16B are now supported image modes for all transpose() operations.
