Python3批量生成带logo的二维码方法

def create_qrcode(url, filename):
  qr = qrcode.QRCode(
    version=1,
    #设置容错率为最高
    error_correction=qrcode.ERROR_CORRECT_H,
    box_size=10,
    border=4,
  )
  qr.add_data(url)
  qr.make(fit=True)
 
  img = qr.make_image()
  #设置二维码为彩色
  img = img.convert("RGBA")
  icon = Image.open('/Users/Jason/Desktop/qrcode/logo.png')
  w, h = img.size
  factor = 4
  size_w = int(w / factor)
  size_h = int(h / factor)
  icon_w, icon_h = icon.size
  if icon_w > size_w:
    icon_w = size_w
  if icon_h > size_h:
    icon_h = size_h
  icon = icon.resize((icon_w, icon_h), Image.ANTIALIAS)
  w = int((w - icon_w) / 2)
  h = int((h - icon_h) / 2)
  icon = icon.convert("RGBA")
  newimg = Image.new("RGBA", (icon_w + 8, icon_h + 8), (255, 255, 255))
  img.paste(newimg, (w-4, h-4), newimg)
 
  img.paste(icon, (w, h), icon)
  img.save('/Users/Jason/Desktop/qrcode/' + filename + '.png', quality=100)
