GeezerVison is showing libexif.github.io — The libexif C EXIF library
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).
Documentation

Download
Source
Download the source code archive by choosing the GitHub repository link for
the subproject you want (in the About
section below) and navigate to its releases page (here's a shortcut
for libexif).
Old releases are available from the historical archive.
Binaries
The libexif project supplies only source code packages. Helpful people
around the world compile the source code and provide binaries for a
number of platforms. Here is a list of some of the sites you can look.
Please report any problems with these binaries to their respective maintainers
and not to libexif project members, as we have nothing to do with
them. In particular, check the version as it may not be the latest and may
therefore suffer from known security issues.
