To use the PDFreactor Ruby API simply copy the PDFreactor.rb to a directory of your webserver where Ruby is enabled (by e.g. CGI or mod-ruby).

Then include the PDFreactor.rb with:

require 'PDFreactor.rb'

With just a few lines you can create and directly show PDFs inside your Ruby webapplication:

pdfreactor = PDFreactor.new()
pdfreactor.setAuthor("Myself")
pdfreactor.setAddLinks(true)
pdfreactor.setAddBookmarks(true)
result = pdfreactor.renderDocumentFromURL("http://www.realobjects.com")
if pdfreactor.getError() != nil
    print "Content-type: text/html\n\n"
    puts "Error during rendering: "+pdfreactor.getError()
else
    print "Content-type: application/pdf\n\n"
    print result
end
