python生成417条形码（PDF417）

#1 生成PDF147的条码图片
bc = Pdf417()
#print bc.render_ps_code('PDF417')
text = '068080835AD000D10701014111'.upper()
img = bc.render(text, options=dict(columns=1,rows=10,eclevel=1,rowmult=1), scale=3)
#img.save(text+'.png', 'png')

#2 生成描述性文字图片
#3 合成为一个新的图片，即最终包含说明的，符合菲亚特规范PDF147的条码图片
