Equivalent to `enc_params=[("chroma", "4xx")]` in old versions. ### Changed - `enc_params` for `save` changed type from `List[Tuple[str, str]]` to `Dict`. Old code will still work, but marked as deprecated. - `libheif_info` now returns also bundled versions of `x265` and `aom`. - `options().avif` marked as deprecated.

Determines what bitness will have 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 uses 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](https://pillow-heif.readthedocs.io/en/latest/image-modes.html) - 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+` (https://github.com/python-pillow/Pillow/pull/6335) ## [0.3.2 - 2022-06-25] ### 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) - Speed optimization for `save` `append_images` parameter - Possible `SEGFAULT` during encoding with some `stride` values. ## [0.3.1 - 2022-06-17] ### 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. ## [0.3.0 - 2022-06-11] ### Added - (HeifImagePlugin, Heif) - `save` now recognizes `exif=` and `xmp=` optional parameters.

Use `class HeifFiletype(IntEnum)`. - IMPORTANT! `heif_brand_*` constants will be deprecated in the future. Use `class HeifBrand(IntEnum)`. - Added `cfg_options` function, to change config when used not as `opener`. Look at `_options.py` for more info. - OPTIONS: `strict` and `avif` - look at `reader.is_supported` function description. - `class HeifErrorCode(IntEnum)` to use in custom exception handler. - `class HeifColorspace(IntEnum)` instead of `heif_colorspace_*` constants. - `class HeifChannel(IntEnum)` instead of `heif_channel_*` constants. - `class HeifChroma(IntEnum)` instead of `heif_chroma_*` constants. - A few examples of how to use. ### Changed - `register_heif_opener` optionally accepts `**kwargs` as parameter, for overwriting values in config, when used as `opener`. - `check_heif_magic` marked as deprecated. Use `is_supported` function instead. - `check_heif` always return `HeifFiletype.NO` when there are less 12 bytes in input. - Warning(`Unssuported HEIF... trying anyway`) was removed. - `(Undecoded)HeifFile` and `HeifImageFile` classes was slightly changed(more consistent now). See the new description in README.md. - Many other improvements and optimizations. - When used as reader, functions `open_heif` and `read_heif` raise `HeifError` exception if file is not valid or broken. ### Fixed - If `color_profile` is `prof` or `rICC` and data empty, `color_profile` will contain `data`=`None` instead of `color_profile`=`None`. - `check_heif`, `is_supported`, `open_heif` and `read_heif` now preserves the file pointer, if input was a file handle. ## [0.1.8 - 2022-03-05] ### Added - Ability to build from source on alpine with arm 7. Thanks to @aptalca ### Changed - `HeifFile` `close` method now frees image decoded data. - Code optimization. ## [0.1.7 - 2022-02-27] ### 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. ## [0.1.6 - 2022-02-10] ### Added - Windows binary wheels. - More tests to `as_opener` module. - Code coverage. ### Changed - Using code formatting: black. - Started changing build algorithms to support PEP 517. - Speed optimizations and adjustments to `as_opener` module. - Added `info[icc_profile]` to `HeifImageFile` when use it as `as_opener`. - Adjustments to `reader` module: - `pillow_heif.open` is in process of deprecation, still available, but you should use `open_heif` instead. - `pillow_heif.check` is in process of deprecation, still available, but you should use `check_heif` instead. - `pillow_heif.read` is in process of deprecation, still available, but you should use `read_heif` instead. ### Fixed - Apple M1 binary wheels now build on Monterey 12.01 instead of 12.2. - HeifError exception class now calls `super` to init all values. ## [0.1.5 - 2022-02-01] ### Added - Apple M1 binary wheels. - Alpine Linux binary wheels. - More auto tests before publishing. ### Changed - libaom bumped from 2.0.0 to 3.2.0 ## [0.1.4 - 2021-11-05] 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.
