python生成417条形码（PDF417）详解编程语言

#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
