Member Function Documentation#

encode()#

void cv::QRCodeEncoder::encode(
const String & encoded_info,
OutputArray qrcode )

Python:

cv.QRCodeEncoder.encode(encoded_info[, qrcode]) -> qrcode

Generates QR code from input string.

Parameters

  • encoded_info — Input string to encode.

  • qrcode — Generated QR code.

encodeStructuredAppend()#

void cv::QRCodeEncoder::encodeStructuredAppend(
const String & encoded_info,
OutputArrayOfArrays qrcodes )

Python:

cv.QRCodeEncoder.encodeStructuredAppend(encoded_info[, qrcodes]) -> qrcodes

Generates QR code from input string in Structured Append mode. The encoded message is splitting over a number of QR codes.

Parameters

  • encoded_info — Input string to encode.

  • qrcodes — Vector of generated QR codes.

create()#

static Ptr< QRCodeEncoder > cv::QRCodeEncoder::create(const QRCodeEncoder::Params & parameters = QRCodeEncoder::Params())

Python:

cv.QRCodeEncoder.create([, parameters]) -> retval

cv.QRCodeEncoder_create([, parameters]) -> retval

Constructor.
