"github.com/boombuler/barcode/qr"
)
func main() {
// Create the barcode
qrCode, _ := qr.Encode("Hello World", qr.M, qr.Auto)
// Scale the barcode to 200x200 pixels
qrCode, _ = barcode.Scale(qrCode, 200, 200)
// create the output file
file, _ := os.Create("qrcode.png")
defer file.Close()
// encode the barcode as png
png.Encode(file, qrCode)
}
```
