Part of making it easier to use is to adopt an <a href="http://www.apple.com/aperture">Aperture</a>-based system of marking the metadata directly in the image itself, and figuring out how to render so many pictures more effectively in my <a href="http://anil.recoil.org/gallery/">gallery</a>.</p> <p>The best library I could find to do the job is <a href="http://www.exiv2.org">Exiv2</a> and its associated Python bindings <a href="http://tilloy.net/dev/pyexiv2/">pyexiv2</a>. They use the rather complex <a href="http://www.boost.org/doc/libs/1_35_0/libs/python/doc/index.html">Boost.Python</a> bindings, which are a total pain to compile on MacOS X Leopard.</p> <p>In order to get it to work:</p> <ul> <li>Use the latest <a href="http://www.finkproject.org">Fink</a> to install: <ul> <li><code>python25</code></li> <li><code>boost1.34.python25</code></li> <li><code>libexiv2</code></li> <li><code>scons</code></li> </ul></li> <li>Download the latest <a href="http://tilloy.net/dev/pyexiv2/download.htm">pyexiv2 distribution</a>, extract it, and drop in my <a href="http://anil.recoil.org/files/pyexiv2/Makefile">exiv2 Leopard Makefile</a> into the extracted directory.</li> <li>Type in: <ul> <li><code>make</code></li> <li><code>sudo make install</code>.</li> </ul></li> <li>Test it out by running python2.5 and experimenting with importing pyexiv2 (see the pyexiv2 <a href="http://tilloy.net/dev/pyexiv2/developers.htm">developer guide</a> for more information.</li> </ul> <p>I'll tidy this up into a fink package sometime, but for now I want to press on with finishing my <a href="http://www.djangoproject.org/">Django</a> experiments.</p> Thu, 17 Apr 2008 11:58:00 +0100 urn:uuid:1c1c8218-945d-4f62-a566-953d1b685766 anil@recoil.org (Anil Madhavapeddy) http://anil.recoil.org/blog/articles/2008/04/17/parsing-exif-iptc-photo-tags-using-pyexiv2-on-leopard hacking macosx
