pi-heif 0.7.0

Python 3.6+ interface to libheif library

pi-heif

This is a light version of Pillow-Heif with more permissive license for binary wheels.

It includes only HEIF decoder and does not support save operations.

All codebase are the same, refer to pillow-heif docs.

The only difference is the name of the imported project.

Install

python3 -m pip install -U pip
python3 -m pip install pi-heif

Example of use as a Pillow plugin

from PIL import Image
from pi_heif import register_heif_opener

register_heif_opener()

im = Image.open("images/input.heic")  # do whatever need with a Pillow image
im.show()

8/10/12 bit HEIF to 16 bit PNG using OpenCV

import numpy as np
import cv2
import pi_heif

heif_file = pi_heif.open_heif("images/rgb12.heif", convert_hdr_to_8bit=False)
heif_file.convert_to("BGRA;16" if heif_file.has_alpha else "BGR;16")
np_array = np.asarray(heif_file)
cv2.imwrite("rgb16.png", np_array)

Get decoded image data as a Numpy array

import numpy as np
import pi_heif

if pi_heif.is_supported("input.heic"):
    heif_file = pi_heif.open_heif("input.heic")
    np_array = np.asarray(heif_file)
