Remarks

This is a class for reading and writing Exif tags in various image file formats.

<b>Note:</b> This class has known issues on some versions of Android. It is recommended to use the AndroidXExifInterface Library since it offers a superset of the functionality of this class and is more easily updateable. In addition to the functionality of this class, it supports parsing extra metadata such as exposure and data compression information as well as setting extra metadata such as GPS and datetime information.

Supported for reading: JPEG, PNG, WebP, HEIF, DNG, CR2, NEF, NRW, ARW, RW2, ORF, PEF, SRW, RAF, AVIF.

Supported for writing: JPEG, PNG, WebP.

Note: JPEG and HEIF files may contain XMP data either inside the Exif data chunk or outside of it. This class will search both locations for XMP data, but if XMP data exist both inside and outside Exif, will favor the XMP data inside Exif over the one outside.
