Hi all, I'm relatively new to Ruby and RMagick. I want to extract IPTC information from JPEG files. Elements that I've already found are : >From RMagick, iptc_profile : http://www.simplesystems.org/RMagick/doc/imageattr... And This, but it doesn't seem to work for : http://studio.imagemagick.org/pipermail/magick-use... Anyone can give me some information ? Thank you all.

Send a JPEG with an IPTC profile in it to rmagick AT rubyforge DOT org and I'll take a look at it.

Before sending you an image, I want to try by myself :) Can you just give me some indications on how-to achieve such a process in Ruby with RMagick ? (if RMagick implements such features) What I want is extracting some of these information : caption, headline, copyright_string, etc. Thank you, Jérémy

RMagick simply provides an interface to the ImageMagick API. The doc for the iptc_profile attribute tells you everything I know about it. If you send me an example image I will try it myself and communicate with the ImageMagick developers if necessary.

It's Ok, I've just found it! RMagick can access IPTC values, via the method get_exif_by_entry([name]). That was too easy! :D Thank you for your proposale! Jérémy

Oups! I was wrong finally. get_exif_by_entry only returns EXIF information, eheh dumb! :D So, is there any way with RMagick to extract, keywords, city, province, country, etc. Jérémy

I'm currently working on it! Writing a class to format the binary IPTC string returned by RMagick.
