Мне нужно вращать изображения, если это необходимо на стороне сервера. Я использовал пакет извлечения метаданных и Apache Commons-Imaging для этих целей, но для некоторых фотографий, сделанных на Android, я не могу получить значения полей ориентации с помощью Java, но любой сайт чтения метаданных EXIF может.
Например:
https://imgbbb.com/image/LVtrUD - изображение
И его метаданные извлекаются с помощью Apache Imaging.

Возможно ли этополучить правильное значение поля ориентации?
