static

Constructor.

Parameters

parameters

QR code encoder parameters QRCodeEncoder::Params

encode()

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

pure virtual

Generates QR code from input string.

Parameters

encoded_info	Input string to encode.
qrcode	Generated QR code.

encodeStructuredAppend()
