EXAMPLE:

webkit = GTK::Webkit.new(string_data, format, options) #creates the webkit object where "format" => 1 . 0(zero) - means you are giving the html string to the first parameter(that is string_data). 2 . 1(one) - future usage. 3 . 2(two) - means you are giving the URI to the first parameter(that is string_data).

printer = webkit.gtk_printer #which returns the printer object, using this printer object you get the pdf content like below printer.pdf_content #returns pdf contenht as a string, then you can save this pdf content to a file or you can render using "send_data"(in the case of download). You can also export to a file using the following printer.export(base_url, filename) #base_url => base directory(like /home/mohanraj/), filename => name of the file, you want to export
