The libexif C EXIF library

is a library written in pure portable C.
reads and writes EXIF metainformation from and to image files.
is licensed under the GNU LESSER GENERAL PUBLIC LICENSE Version 2.1 (LGPL).
runs under POSIX systems (e.g. GNU/Linux, xBSD, MacOS X, Windows, etc.).

Digital cameras store a surprising amount of information inside each picture they take, in a normally invisible format known as EXIF. Everything from photo basics like the camera shutter speed and aperture to the GPS location and even the name of the camera owner can be hidden inside each photograph. libexif is a library that lets you access that data from within a computer program. Some simple applications called exif and gexif are also supplied alongside libexif that use it to view EXIF data from the command-line or GUI (respectively).
