cykooz-heif

cykooz.heif is simple python wrapper for the library libheif-rs.

RawHeifImage is a simple wrapper around low level HEIF-decoder.

Usage Examples

Read HEIF-image from file:

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:

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):

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')
