Instantiation QRCode class.
:params version: an integer value from 1 to 40 that controls the size of QRCode.
:params error_correction: L About 7% or less errors can be corrected, M(default) 15%, H 25%.
:params box_size: control how many pixels each "box" of the QRCode is.
:params border: control how many boxes thick the border should be(default 4).
'''
qr = QRCode(version=1, error_correction=qrcode.constants.ERROR_CORRECT_L,

)
'''Code infomation.'''
data = "https://blog.csdn.net/Xin_101"
'''Add information to Code.'''
qr.add_data(data=data)
'''Enable cololr setting.'''
qr.make(fit=True)
'''Generate image.'''
image = qr.make_image(fill_color="black", back_color="yellow")

3 二维码信息识别
import zxing
'''Instantiation BarCodeReader class.'''
readapi = zxing.BarCodeReader()
code_info = readapi.decode("./images/qrcode.png")
print("QRCode inofs: {}".format(code_info))
print("QRCode info: {}".format(code_info.parsed))
- Result
QRCode inofs: BarCode('https://blog.csdn.net/Xin_101', 'https://blog.csdn.net/Xin_101', 'QR_CODE', 'URI', [(75.0, 255.0), (75.0, 75.0), (255.0, 75.0), (225.0, 225.0)])
