- 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.
-
-
- USAGE
- -----
-
- We have started documenting the libexif API using doxygen and are making
- the results available at http://libexif.sourceforge.net/api/
-
- Until someone writes some better documentation however, you need to refer
- to the header files.
-
- The short test-program test/test-mem illustrates how to create valid
- EXIF data from scratch, how to save EXIF data and how to load EXIF data
- from data in memory. Don't hesitate to contact us
- (<libexif-devel@lists.sourceforge.net>) if you've got any questions
- on how to use libexif.
-
- To link to libexif into your own package, we recommend using the
- pkgconfig utility (cf. http://pkg-config.freedesktop.org/wiki/). For
- your convenience, libexif both provides libexif-uninstalled.pc and
- installs libexif.pc.
-
-
- 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).
- - digicam:
- If you would like to migrate your program to use libexif or add EXIF support
- to it, don't hesitate to contact the authors.

-
- LIBRARIES
- ---------
-
- I know of the following libraries that use or have been inspired by libexif:
- - pel: PHP-Code (http://pel.sourceforge.net)
-
-
- AUTHORS
- -------
-
- libexif has originally been written by Curtis Galloway
- <curtisg@users.sourceforge.net>. Because of the original design not
- supporting editing and saving, Lutz Mⁿller <lutz@users.sourceforge.net>
- rewrote libexif from scratch.
