Methods

decode(InputArray img, {VecPoint? points, Mat? straightCode}) → (String, VecPoint?, Mat?)
Decode decodes QR code in image once it's found by the detect() method. Returns UTF8-encoded output string or empty string if the code cannot be decoded.
decodeCurved(InputArray img, VecPoint points, {OutputArray? straightQRcode}) → (String, Mat)
Decodes QR code on a curved surface in image once it's found by the detect() method.
detect(InputArray input, {VecPoint? points}) → (bool, VecPoint)
Detect detects QR code in image and returns the quadrangle containing the code.
detectAndDecode(InputArray img, {VecPoint? points, OutputArray? straightCode}) → (String, VecPoint, Mat)
DetectAndDecode Both detects and decodes QR code.
detectAndDecodeCurved(InputArray img, {VecPoint? points, Mat? straightQRcode}) → (String, VecPoint, Mat)
Both detects and decodes QR code on a curved surface.
detectAndDecodeMulti(InputArray img) → (bool, List<String>, VecPoint, VecMat)
Detects QR codes in image, finds the quadrangles containing the codes, and decodes the QRCodes to strings.
detectMulti(InputArray img, {VecPoint? points}) → (bool, VecPoint)
Detects QR codes in image and finds of the quadrangles containing the codes.
dispose() → void
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
