java - Android 照片上的 EXIF 方向字段为空

Question

如果服务器端需要，我需要旋转图像。为此，我使用了metadata-extractor包和apache commons-imaging，但是对于在Android上拍摄的一些照片，我无法使用java获取任何方向字段值，但任何exif元数据阅读器网站都可以。

例如:

https://imgbbb.com/image/LVtrUD -- 图片

它是使用 Apache Imaging 提取的元数据。

是否可以获得正确的方向字段值？

终于使用 ExifTool ( https://www.sno.phy.queensu.ca/~phil/exiftool/ ) 和 Java Wrapper ( https://github.com/rkalla/exiftool ) 解决了我的问题
