I like HEIF(HEIC) images because they are very lightweight and efficiently compressed.However sometimes thier rotation is not recognized.For example,- photos taken by iPhone : OK- Rotation info is included in both EXIF and IROT boxes (which are defined HEIF container format).- photos generated by Android Phones : NG- Rotation info is included only in IROT boxes.It seems that iOS checks only rotation info in EXIF, not in IROT boxes.Is it a bug of iOS framework? or are there any workarounds to avoid this phenomenon?
