libexif
-------
DESCRIPTION
-----------
libexif is a library for parsing, editing, and saving EXIF data. It is
intended to replace lots of redundant implementations in command-line
utilities and programs with GUIs.
FEATURES
--------
libexif supports parsing, editing and saving of EXIF data. In addition, it
has gettext support. All EXIF tags described in EXIF standard 2.1
are supported.
REQUIREMENTS
------------
libexif is written in plain C and does not require any additional library.
LIMITATIONS
-----------
libexif can only handle some maker notes, and even those not very well. More
work needs to be done. Note that libmnote has been merged with libexif - it
is no longer needed.
FRONTENDS
---------
Right now, I know of the following frontends to libexif:
- exif: A small command-line utility to show EXIF information in JPEG
files (http://www.sourceforge.net/projects/libexif).
- gexif: A GTK+ frontend for editing EXIF data
(http://www.sourceforge.net/projects/libexif).
- gphoto2: A command-line frontend to libgphoto2, a library to access a
wide range of digital cameras (http://www.gphoto.org).
- gtkam: A GTK+ frontend to libgphoto2 (http://www.topfrose.de).
- thirdeye: Digital photos organizer and driver for eComStation
(http://ecomstation.ru/thirdeye).
If you would like to migrate your program to use libexif or add EXIF support
to it, don't hesitate to contact the authors.
BUGS
----
libexif includes a 'libjpeg' that is 'educational code to illustrate the
syntax of JPEG files'. Please ignore it. It is a bug that it is
distributed, but I think it may be useful for other people.
AUTHORS
-------
libexif has originally been written by Curtis Galloway
<curtisg@users.sourceforge.net>. Because of the original design not
supporting editing and saving, Lutz Mller <lutz@users.sourceforge.net>
rewrote libexif from scratch.
