7 libexif is a library for parsing, editing, and saving EXIF data. It is
8 intended to replace lots of redundant implementations in command-line
9 utilities and programs with GUIs.
14 libexif supports parsing, editing and saving of EXIF data. In addition, it
15 has gettext support. All EXIF tags described in EXIF standard 2.1
21 libexif is written in plain C and does not require any additional library.
26 libexif can only handle some maker notes, and even those not very well. More
27 work needs to be done. Note that libmnote has been merged with libexif - it
33 Right now, I know of the following frontends to libexif:
34 - exif: A small command-line utility to show EXIF information in JPEG
35 files (http://www.sourceforge.net/projects/libexif).
36 - gexif: A GTK+ frontend for editing EXIF data
37 (http://www.sourceforge.net/projects/libexif).
38 - gphoto2: A command-line frontend to libgphoto2, a library to access a
39 wide range of digital cameras (http://www.gphoto.org).
40 - gtkam: A GTK+ frontend to libgphoto2 (http://www.topfrose.de).
41 - thirdeye: Digital photos organizer and driver for eComStation
42 (http://ecomstation.ru/thirdeye).
43 If you would like to migrate your program to use libexif or add EXIF support
44 to it, don't hesitate to contact the authors.
49 I know of the following libraries that use or have been inspired by libexif:
50 - pel: PHP-Code (http://pel.sourceforge.net)
55 libexif includes a 'libjpeg' that is 'educational code to illustrate the
56 syntax of JPEG files'. Please ignore it. It is a bug that it is
57 distributed, but I think it may be useful for other people.
62 libexif has originally been written by Curtis Galloway
63 <curtisg@users.sourceforge.net>. Because of the original design not
64 supporting editing and saving, Lutz Müller <lutz@users.sourceforge.net>
65 rewrote libexif from scratch.
