PDF::Writer：#polygon

まんま

require 'pdf/writer'

pdf = PDF::Writer.new

points = [ [ 10, 10 ],          # starting point
           [ 20, 20, :curve ],  # first control point
           [ 30, 30 ],          # second control point
           [ 40, 40 ],          # ending point of the curve.
         ]
pdf.polygon(points)
pdf.stroke

File.open("2008020100.pdf", "wb") { |f| f.write pdf.render }

や

require 'pdf/writer'
