Member Function Documentation

create()

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

static

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

Constructor.

Parameters

parameters

QR code encoder parameters QRCodeEncoder::Params

encode()

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

pure virtual

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()

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

pure virtual

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
