A beta tester reported an issue with incorrectly rotated .heic images (taken with an iPhone XS Max).
If you find any other mis-rotated .heic images, and they don’t have any private content, please send an example to support@photostructure.com so we can make sure the bugfix works on your files too.
Update: the next version of PhotoStructure will switch from in-process HEIC conversions (which requires a compilation) to using an external tool (much like how ffmpeg or VLC are utilized for transcoding jobs).
As long as heif-convert is in your PATH, HEIF images will be imported and viewed.
This method turns out handle these orientations correctly, be faster (!), and much easier to support from all of PhotoStructure’s various editions.
