DESCRIPTION
libiptcdata is a library for manipulating the International Press Telecommunications Council (IPTC) metadata stored within multimedia files such as images. The library provides routines for parsing, viewing, modifying, and saving this metadata. The library is licensed under the GNU Library General Public License (GNU LGPL).
The library implements the standard described at http://www.iptc.org/IIM
The code itself was inspired by the libexif library: http://sourceforge.net/projects/libexif, written by Lutz Müller. Together, libexif and libiptcdata provide a complete metadata solution for image files.
LIMITATIONS
The current implementation of libiptcdata only supports extracting IPTC data from JPEG files (although it can decode raw IPTC data from any source as long as your application provides the data directly). The format for storing IPTC in JPEG files is a de-facto standard developed by Adobe.
