RETURN TYPEOwned native handle

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Native object: release it with using or delete(). Factories can return null; check before calling methods.

QR code encoder.

Constructors and members

static create

QRCodeEncoder.create: Constructor

create(parameters: QRCodeEncoder_Params): QRCodeEncoder | null;

2 available overloads

create(): QRCodeEncoder | null;

create(parameters: QRCodeEncoder_Params): QRCodeEncoder | null;

parameters

QR code encoder parameters QRCodeEncoder::Params

Returns

The QRCodeEncoder | null result.

Upstream declaration ↗

clone

Create another handle to the same native object. This retains the object without copying its pixels or algorithm state; dispose both handles separately.

clone(): this;

Returns

The this result.

encode

Generates QR code from input string.

encode(encoded_info: EmbindString, qrcode: Mat): void;

encoded_info

Input string to encode.

qrcode

Output destination, filled by the native operation. Generated QR code.

Upstream declaration ↗

encodeStructuredAppend

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

encodeStructuredAppend(encoded_info: EmbindString, qrcodes: MatVector): void;

encoded_info

Input string to encode.

qrcodes

Output destination, filled by the native operation. Vector of generated QR codes.
