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 Until someone writes some documentation, you need to refer to the header
34 files. The short test-program test/test-mem illustrates how to create valid
35 EXIF data from scratch, how to save EXIF data and how to load EXIF data
36 from data in memory. Don't hesitate to contact us
37 (<libexif-devel@lists.sourceforge.net>) if you've got any questions
38 on how to use libexif.
43 Right now, I know of the following frontends to libexif:
44 - exif: A small command-line utility to show EXIF information in JPEG
45 files (http://www.sourceforge.net/projects/libexif).
46 - gexif: A GTK+ frontend for editing EXIF data
47 (http://www.sourceforge.net/projects/libexif).
48 - gphoto2: A command-line frontend to libgphoto2, a library to access a
49 wide range of digital cameras (http://www.gphoto.org).
50 - gtkam: A GTK+ frontend to libgphoto2 (http://www.topfrose.de).
51 - thirdeye: Digital photos organizer and driver for eComStation
52 (http://ecomstation.ru/thirdeye).
54 If you would like to migrate your program to use libexif or add EXIF support
55 to it, don't hesitate to contact the authors.
60 I know of the following libraries that use or have been inspired by libexif:
61 - pel: PHP-Code (http://pel.sourceforge.net)
66 libexif has originally been written by Curtis Galloway
67 <curtisg@users.sourceforge.net>. Because of the original design not
68 supporting editing and saving, Lutz Müller <lutz@users.sourceforge.net>
69 rewrote libexif from scratch.
