This package contains the following known limitations:
- Accessing SLONG tags is not supported (since no IFD tags in the EXIF specification are SLONG type).
- EXIF IFDs cannot be added to images that only contain IFD 0 (and/or IFD 1). However, GPS IFDs can be inserted if there’s a subsequent IFD 1 segment. When adding metadata to a previously non-APP1 image, this is not a concern since the package adds empty 0, EXIF, and GPS IFDs.
- Modifying Windows XP tags is not supported.
