This library is wrapper for the Exiftool command-line application (www.sno.phy.queensu.ca/~phil/exiftool) written by Phil Harvey. Read and write access is done in a clean OO manner.

Ruby 1.9 or higher and an installation of the Exiftool command-line application at least version 7.65. If you run on Ruby 1.8 or with a prior exiftool version install mini_exiftool version 1.x.x. Instructions for installation you can find under www.sno.phy.queensu.ca/~phil/exiftool/install.html .

Alternatively Wil Gieseler has bundled a meta-gem that eliminates the need for a separate Exiftool installation. Have a look at github.com/wilg/mini_exiftool_vendored or rubygems.org/gems/mini_exiftool_vendored .

First you need Exiftool (see under Requirements above). Then you can simply install the gem with

gem install mini_exiftool

If you need to support older versions of Ruby or exiftool (see Requirements above)

gem install --version "< 2.0.0" mini_exiftool

In general MiniExiftool is very intuitive to use as the following examples show:

# Reading meta data
photo = MiniExiftool.new 'photo.jpg'
puts photo.title

# Writing meta data
photo = MiniExiftool.new 'photo.jpg'
photo.title = 'This is the new title'
photo.save

# Copying meta data
photo = MiniExiftool.new('photo.jpg')
photo.copy_tags_from('another_photo.jpg', :author)

For further information about using MiniExiftool read the Tutorial.rdoc in the project root folder and have a look at the examples in directory examples.

The code is hosted in a git repository on Gitorious at gitorious.org/mini_exiftool and github at github.com/janfri/mini_exiftool feel free to contribute!
