ImageScience is a clean and happy Ruby library that generates thumbnails -- and kicks the living crap out of RMagick. Oh, and it doesn't leak memory like a sieve. :) This fork does not require RubyInline. For more information (on the original variant), see http://seattlerb.rubyforge.org/ImageScience.html
