cykooz.heif
***********
``cykooz.heif`` is simple python wrapper for the library `libheif-rs <https://crates.io/crates/libheif-rs>`_.
``RawHeifImage`` is a simple wrapper around low level HEIF-decoder.
`CHANGELOG <https://github.com/Cykooz/cykooz.heif/blob/master/CHANGES.rst>`_
Usage Examples
==============
Read HEIF-image from file:
.. code-block:: python
from cykooz.heif.image import RawHeifImage
img = RawHeifImage.from_path('data/test.heif')
assert img.width == 3024
assert img.height == 4032
assert img.mode == 'RGB'
assert len(img.data) == 36578304
assert img.stride == 9072
assert len(img.exif) == 2026
Read HEIF-image from file-like object:
.. code-block:: python
from cykooz.heif.image import RawHeifImage
with open('data/test.heif') as fp
img = RawHeifImage.from_stream(fp)
assert img.width == 3024
assert img.height == 4032
Also package provides an opener plugin for ``PIL`` (``Pillow``):
.. code-block:: python
from PIL import Image
from cykooz.heif.pil import register_heif_opener
register_heif_opener()
img = Image.open('data/test.heif')
assert isinstance(img, Image.Image)
assert img.size == (3024, 4032)
assert img.mode == 'RGB'
assert img.getpixel((100, 100)) == (73, 74, 69)
img.save('test.jpg', 'JPEG')
