===================================================================================================
   def make_pdf
        # prepare DPF file on local file system in User folder
        #
        # for generate PDF we use open source pure Ruby library PDF-Writer
        # Homepage::  http://rubyforge.org/projects/ruby-pdf/
        # Copyright:: 2003-2005, Austin Ziegler
        #
        # PDF-Writer also require few additional Ruby libs:
        #   color
        #   transaction-simple
        #   thread
        #
        # You can see their Ruby code in rodes platform extension folder:
        #  [Rhodes root]/lib/extensions
        #
        # for include that libs to your application you should add next extsnions to your application extension list in your application build.yml :
        # "pdf-writer", "thread"
        #

         pdf = PDF::Writer.new
       ### i have used all the three method for adding imgae in pdf   
      pdf.image "#{Rho::RhoApplication.get_base_app_path()}public/images/loading_1.JPEG", :resize => 0.75
    
      pdf.add_image("#{Rho::RhoApplication.get_base_app_path()}public/images/Jellyfish.jpg", 0,0)
     
      pdf.add_image_from_file("#{Rho::RhoApplication.get_base_app_path()}public/images/Jellyfish.jpg",  100,100)
