How to use

Just import once before opening an image.

from PIL import Image, ImageOps
import HeifImagePlugin

ImageOps.exif_transpose(image, in_place=True)
# requires `heif-enc` binary with installed codecs or plugins
image.save('test.avif')

0.4.0

  • Bypass some decoding errors when ImageFile.LOAD_TRUNCATED_IMAGES is True.

0.3.2

  • Depends on latest pyheif.

0.3.1

! This version requires pyheif with pyheif.open API. As of 2021.11.25 this API isn't released and is in pyheif's master. See install-pyheif-master-pillow-latest target in the Makefile to install it.

  • Fixed potential vulnerability with arbitrary data in exif metadata.

0.3.0

! This version requires pyheif with pyheif.open API. As of 2021.11.25 this API isn't released and is in pyheif's master. See install-pyheif-master-pillow-latest target in the Makefile to install it.

  • pyheif.open API is used for lazy images loading.
  • Fixed an error when the plugin tries to load any ISOBMFF files.
  • AVIF files should work before, but now this is official.
  • Patched versions of pyheif and libheif with exposed transformations is supported. In this case opened image isn't transformed on loading and orientation is stored in EXIF Orientation tag like for all other image formats. This is faster and consumes less memory.

0.2.0

  • No need to register, works after import.
  • Fill info['icc_profile'] on loading.
  • Close and release file pointer after loading.
  • Deconding without custom HeifDecoder(ImageFile.PyDecoder).
