github.com/dsoprea/go-exif/v2 (go): Package exif parses raw EXIF information given a block of raw EXIF data. It can also construct new EXIF information, and provides tools for doing so. This package is not involved with the parsing of particular file-formats.  The EXIF data must first be extracted and then provided to us. Conversely, when constructing new EXIF data, the caller is responsible for packaging this in whichever format they require.
