  img=img.convert('RGBA') #返回一个转换后的图像的副本 
  datas=img.getdata()

      newData.append((255,255,255,0)) 
    else: 
      newData.append(item) 
  img.putdata(newData)  #赋给图片新的像素数据 
  return img

  p1_name="E:\\code\\python\\test\\day01\\001.jpg"

  #打开两张png图片，注意为当前路径 
  p1_image=Image.open(p1_name)

  draw=ImageDraw.Draw(p1_image) #在p1_image上绘制文字，图像 
  draw.text((152,8),u'12',font=usr_font) 
  p1_image.save("final.png","PNG")
