QRCode used to create 2D QR Code barcodes. Please see Example_20. @author Kazuhiko Arase

func NewQRCode

func NewQRCode(str string, errorCorrectLevel int) *QRCode

NewQRCode is used to create 2D QR Code barcodes. @param str the string to encode. @param errorCorrectLevel the desired error correction level.

func (*QRCode) DrawOn

func (qrcode *QRCode) DrawOn(page *pdfjet.Page) []float32

DrawOn draws this barcode on the specified page. @param page the specified page. @return x and y coordinates of the bottom right corner of this component.

func (*QRCode) SetColor

func (qrcode *QRCode) SetColor(color int32)

SetColor sets the color of the barcode.

func (*QRCode) SetLocation
