import (

	"image/png"

	"os"

	"github.com/boombuler/barcode"

	"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)

}

```
