v0.4.0

Added

• (Heif) - Numpy array interface support.
• (Heif) - add_from_bytes method and from_bytes function added. Allows to read 16-bit color images with OpenCV(or any other library) and save it as 10(12) bit HEIF.
• (Heif) - convert_to method to HeifImage to provide an easy way to open 10 or 12 bit images as 16 bit for OpenCV(or any other library)
• (Heif, HeifImagePlugin) - support for saving images from I, I;16, BGRA;16, BGR;16, BGRA, BGR modes.
• (Heif) - added save_to_12bit to options, default False. Determines to what bitness will be converted 16 bit images during saving.

Changed

• IMPORTANT!!! 10/12 bit images changed their byte order from Big Endian to Little Endian. Probably no one still use that API, but who knows...
• (Heif) - HeifFile.chroma and HeifFile.color properties was removed(they were not documented so probably no one will notice this), that info now stored in mode.
• (Heif, HeifImagePlugin) - mode for 10/12 bits was changed and accepts wider range of values, look here
• Docs were updated & rewritten to reflect all those changes.

Fixed

• Examples were fixed & rewritten(were broken from 0.3.1+ versions).
• exif loading in HEIF sequence for Pillow 9.2+ (python-pillow/Pillow#6335)

v0.3.2

Fixed

• Support of saving images with mode="1" in "L" mode.
• Images with mode="L" are now saved natively in Monochrome mode(increase speed & decreased required memory and a bit less size) #26
• Speed optimization for save append_images parameter
• Possible SEGFAULT during encoding with some stride values.

v0.3.1

Added

• (Heif) - HeifFile gets images: List[HeifImage] and alternative method of changing order of images by editing it.
• (HeifImagePlugin) - info image dictionary can be now edited in place and it will be saved for image sequences.

Changed

• Updated docs.

Fixed

• (HeifImagePlugin) Again fixing image order, for Pillow plugin it was not fixed fully in 0.3.0.
• Optimizing code.

v0.3.0

Added

• (HeifImagePlugin, Heif) - save now recognizes exif= and xmp= optional parameters. Works as in other Pillow plugins. #25
• (HeifImagePlugin, Heif) - save now recognizes primary_index optional parameter.
• (HeifImagePlugin, Heif) - info["primary"] value.
• (Heif) - primary_index method to HeifFile class.
• Docs: Encoding
• Docs: Changes in Order Of Images

Changed

• Changed image order when multiply images present, HeifFile points to primary image as it was before, but it can be not the first image in a list.
• When using as a Pillow's plugin the only way to know is an image Primary or not is to perform check of info["primary"] value.
• (Heif) - optimized code of HeifImageThumbnail, added get_original method.

Fixed

• (HeifImagePlugin) - save bug, when first frame was saved instead of current.
• Minor usage fixes and optimizations.

v0.2.5

Added

• (HeifImagePlugin) - support for PIL.ImageFile.LOAD_TRUNCATED_IMAGES flag.
• (Windows, encoder) - encoding of 10 and 12 bit images. #24

Changed

• (Windows) - replaced vcpkg build by MSYS2(MinGW) build, report of any possible bugs you see.

v0.2.1

Added

• (Windows) Build script by default assumes that libheif installed in C:\vcpkg\installed\x64-windows, if VCPKG_PREFIX environment is missing.
• (Heif) reader_add_thumbnail and reader_remove_image examples.
• (Heif) to_pillow method and adjusted examples to use it.

Changed

• (Heif) Removed HeifSaveMask, get_img_thumb_mask_for_save that was previously introduced, instead added __delitem__ to HeifFile.
• All thumbnails encoding features reworked, to simplify api. See add_thumbnails methods in HeifFile and HeifImage classes.

Fixed

• (HeifImagePlugin) Fixed palette images with bytes transparency conversion. #21 (@Jarikf)
• (Heif) Raises ValueError when trying to save empty(no images) file.
• (HeifImagePlugin) Skips images with sizes = 0 during save, if there is no images, raise ValueError.
• (HeifImagePlugin) Memory optimizations, when there is only one image in file.
• Added licenses for libraries in binary wheels.
• (Windows) Fix docs for building and developing.
• (Heif) add_from_pillow method, now adds thumbnails from Pillow if it is HeifImageFile(ImageFile.ImageFile) class.

v0.1.7

Added

• Added manylinux2014_i686 wheels.
• Integration of PEP 517 in progress, added new instructions for building from source.

Changed

• Making code cleaner, renamed cffi module from pillow_heif.libheif to _pillow_heif_cffi.
• libaom bumped from 3.2.0 to 3.3.0

Fixed

• Fixed AttributeError when calling Image.verify. Thanks @zijian-hu for reporting.

v0.1.4

First normal working release.

Added

• Python 3.10 wheels.
• Added libaom library to linux build.
• More tests.

Changed

• Code refactoring, readme update.

Fixed

• Bug with header check when used as plugin for Pillow with as_opener function. Thanks for this to @DimonLavron
