[digiKam-users] Errors in showing HEIF/HEIC images from Apple devices

[Thomas]

Hi Maik,


I would be happy to share a  HEIF image in portrait mode with you and 
Gilles. However, I do not like to post it here in the list as it 
contains sensitive information such as GPS location data, etc.


May I send one to both your e-mail addresses directly?
