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.
15 libexif supports parsing, editing and saving of EXIF data. In addition, it
16 has gettext support. All EXIF tags described in EXIF standard 2.1
23 libexif is written in plain C and does not require any additional library.
29 libexif can only handle some maker notes, and even those not very well. More
30 work needs to be done. Note that libmnote has been merged with libexif - it
37 We have started documenting the libexif API using doxygen and are making
38 the results available at http://libexif.sourceforge.net/api/
40 Until someone writes some better documentation however, you need to refer
43 The short test-program test/test-mem illustrates how to create valid
44 EXIF data from scratch, how to save EXIF data and how to load EXIF data
45 from data in memory. Don't hesitate to contact us
46 (<libexif-devel@lists.sourceforge.net>) if you've got any questions
47 on how to use libexif.
49 To link to libexif into your own package, we recommend using the
50 pkgconfig utility (cf. http://pkg-config.freedesktop.org/wiki/). For
51 your convenience, libexif both provides libexif-uninstalled.pc and
58 Right now, I know of the following frontends to libexif:
59 - exif: A small command-line utility to show EXIF information in JPEG
60 files (http://www.sourceforge.net/projects/libexif).
61 - gexif: A GTK+ frontend for editing EXIF data
62 (http://www.sourceforge.net/projects/libexif).
63 - gphoto2: A command-line frontend to libgphoto2, a library to access a
64 wide range of digital cameras (http://www.gphoto.org).
65 - gtkam: A GTK+ frontend to libgphoto2 (http://www.topfrose.de).
66 - thirdeye: Digital photos organizer and driver for eComStation
67 (http://ecomstation.ru/thirdeye).
69 If you would like to migrate your program to use libexif or add EXIF support
70 to it, don't hesitate to contact the authors.
76 I know of the following libraries that use or have been inspired by libexif:
77 - pel: PHP-Code (http://pel.sourceforge.net)
83 libexif has originally been written by Curtis Galloway
84 <curtisg@users.sourceforge.net>. Because of the original design not
85 supporting editing and saving, Lutz Müller <lutz@users.sourceforge.net>
86 rewrote libexif from scratch.
