A simple command-line tool that exports exif information as json. The json is a flat map of key / values and is pretty-printed and dumped into stdout.
exif-json <image-file>
The json will be dumped into stdout.
The code in this package is a simple wrapper. The code is rust, so you'll need rust setup to compile it. kamadak-exif is used to parse out the exif data, and serde_json is used to generate the json.
