Struct heif_decoding_options: wrong total size

[hamzabidi]

In a fastapi project, i have this method:

   @staticmethod
    def ios_image_converter(file: UploadFile) -> Tuple[UploadFile, str]:
        # source
        source_extension = 'heic'
        source_content_type = 'image/heif'

       # target
        target_extension = 'jpg'
        target_format = 'JPEG'
        target_content_type = 'image/jpeg'

        # source type checking
        if file.content_type != source_content_type:
            raise Exception(f"expected file type 'image/heif', got {file.content_type}")

        # converting
        heif_file = pyheif.read(file.file.read())
        image = Image.frombytes(
            heif_file.mode,
            heif_file.size,
            heif_file.data,
            "raw",
            heif_file.mode,
            heif_file.stride
        )

        io = BytesIO()
        image.save(io, format=target_format)
        io.seek(0)

        # saving
        upload_file = UploadFile(io)
        upload_file.filename = file.filename.lower().replace(f'.{source_extension}', f'.{target_extension}')

        return upload_file, target_content_type

When I run it locally (ubuntu 22 LTS), I get no errors. But when I deploy it on a container based on the python:3.8-alpine image, I get this error:

File '/home/python/app/src/api/api_v1/endpoints/dossier.py', line 195, in dossier_piece_post file, content_type = FileService.ios_image_converter(file) File '/home/python/app/src/api/api_v1/services/FileService.py', line 57, in ios_image_converter heif_file = pyheif.read(file.file.read()) File '/usr/local/lib/python3.8/site-packages/pyheif/reader.py', line 103, in read return heif_file.load() File '/usr/local/lib/python3.8/site-packages/pyheif/reader.py', line 47, in load self.data, self.stride = _read_heif_image(self._heif_handle, self) File '/usr/local/lib/python3.8/site-packages/pyheif/reader.py', line 402, in _read_heif_image p_options.ignore_transformations = int(not heif_file.apply_transformations) ffi.error: struct heif_decoding_options: wrong total size (cdef says 48, but C compiler says 72). fix it or use '...;' as the last field in the cdef for struct heif_decoding_options to make it flexible

installed libs on my alpine pods:

libheif-1.16.2-r0
libheif-dev-1.16.2-r0

Any help please !

I'm having the same issue running this on macOS py3.11.5

I'm having same problem as CyberFit.

Same error on slightly older Python. The file in question is a recent HEIC from an iPhone running iOS 16.6.1.

This is probably a duplicate of #84 -- installing from master as directed in that issue resolves the problem.

when installing from master on M1 old error has returned fatal error: 'libheif/heif.h' file not foun i can install it through pip install pyheif but then Struct heif_decoding_options: wrong total size occurs

[derSoerrn95]

I have the same problem as @davidcz95

For anyone still on this thread, I found at least a temporary workaround using the pillow_heif module.

from pillow_heif import register_heif_opener
from PIL import Image

register_heif_opener()

def load_heic_image(heic_file_path):
    # obtain the image data
    image = Image.open(heic_file_path)
    return image

# Replace with your HEIC file path
heic_file_path = 'foo.heic'
image = load_heic_image(heic_file_path)

Hope this helps.

Another workaround (installing from this repo didn't work for me because it would try to build against an incompatible version of libheif) is to downgrade to Python 3.11. I had upgraded to Python 3.12 but there is no pyheif wheel for it.

I finally found another way to do it !

` from io import BytesIO from typing import Final

from PIL import Image from fastapi import UploadFile, File from pillow_heif import register_heif_opener from starlette.datastructures import Headers

from src.utils.mimes_type_enum import MimeTypeEnum

SOURCE_EXTENSION: Final[str] = 'heic' SOURCE_CONTENT_TYPE: Final[MimeTypeEnum] = MimeTypeEnum.HEIC TARGET_EXTENSION: Final[str] = 'png' TARGET_FORMAT: Final[str] = 'PNG' TARGET_CONTENT_TYPE: Final[MimeTypeEnum] = MimeTypeEnum.PNG

async def convert_to_png(file: UploadFile) -> UploadFile:

source type checking

if file.content_type != SOURCE_CONTENT_TYPE.value:
    raise Exception(f"expected file type {SOURCE_CONTENT_TYPE.value}, got {file.content_type}")

register_heif_opener()

with Image.open(file.file) as image:
    io = BytesIO()
    image.save(io, format=TARGET_FORMAT)
    io.seek(0)

# saving
upload_file = UploadFile(
    io,
    filename=file.filename.lower().replace(f'.{SOURCE_EXTENSION}', f'.{TARGET_EXTENSION}'),
    headers=Headers({'Content-Type': TARGET_CONTENT_TYPE.value})
)

return upload_file

`

I use the register_heif_opener() function to registers a Pillow plugin for HEIF format. To get it, you will need to install the pillow-heif lib pip install pillow-heif.

Thank you @malekinho8 for the idea ;)
