Hi,

when running this with a single heic image with the static image generation (sigal) which uses pillow then i get:

Is this familiar ? Any tip ?

Hi!

Want to share with you my recent issue, that I created for another pyheif library, just don't want to copy it, but want to inform you about bug that I found. I believe that one day you will fix it.

bigcat88/pillow_heif#8

Thank you for your attention!

Good Day,

I'm getting the following when trying to install on Windows 10 with python 3.6 with library [email protected] and [email protected]

build\temp.win-amd64-3.6\Release\_libheif_cffi.c(570): fatal error C1083: Cannot open include file: 'libheif/heif.h': No such file or directory error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community\\VC\\Tools\\MSVC\\14.16.27023\\bin\\HostX86\\x64\\cl.exe' failed with exit status 2

Do I need to have another library installed before installing this one?

Hi, I want to use pyheif 0.6.1 but pyheif-pillow-opener pin the pyheif version to 0.5.1.

Expect change to version>=0.5.1 here:

Hi,

Thanks for developing this extension to Pillow. I had a question regarding performance converting a .heic to a .jpg file. Running heif-convert is about twice as fast as doing:

import pillow_heif.HeifImagePlugin

img = Image.open(path_heic)
img.save(path_jpg)

Is this expected? For 100 images, heif-convert took 42 seconds, pillow_heif took 75 seconds (threaded), and 208 seconds using one thread.

Thanks,

Hi, @ciotto!

I'm one of the Pillow developers and I created a fork of this plugin with many bug fixes. It called heif-image-plugin. Also I working on many changes in Pyheif and even some changes in libheif to ensure first-class HEIF images support in Pillow.

I understand that at one time pyheif-pillow-opener was necessary step and appreciate it. However since I don't see any activity in the repository I assume that there are no people who interested in further development (please, correct me if I wrong).

I propose to add a description that the project is not on actively developed and optionally add a link to heif-image-plugin.

With respect to your work, Alex.

Hello,

when passing a Flask's FileStorage as fp to the open method of Pillow's Image this plugin does not set the size property which results in image being rejected because of this check in ImageFile..

Given that _open in the plugin sets _size correctly, a little workaround I used in my code - is to just set size to _size and re-register open for heif with my wrapper. However it would be better to have it not require modification on my side.

I tried to use pyheif_pillow_opener, but can't get it to work.

>>> from PIL import Image
>>> from pyheif_pillow_opener import register_heif_opener
>>> register_heif_opener()
>>> img = Image.open(".../heif.heic")
...
PIL.UnidentifiedImageError: cannot identify image file

The test file is available here.
I'm using a Ubuntu 20.04 derivative, pyheif 0.5.1, libheif1 1.11.0, and libde265-0 1.0.8.
