+The library doesn't take care of the quiet zones which are required by some barcode types.
+You use the following wrapper to create a quiet zone:
+
+```golang
+type QuietZone struct {
+	width   int
+	barcode barcode.Barcode
+}
+
+func (qz QuietZone) At(x, y int) color.Color {
+	bounds := qz.barcode.Bounds()
+	w := bounds.Dx()
+	h := bounds.Dy()
+	if x < qz.width || x >= w+qz.width || y < qz.width || y >= h+qz.width {
+		return color.White
+	}
+	return wb.barcode.At(x-qz.width, y-qz.width)
+}
+
+func (qz QuietZone) Bounds() image.Rectangle {
+	b := qz.barcode.Bounds()
+	return image.Rect(0, 0, b.Dx()+2*qz.width, b.Dy()+2*qz.width)
+}
+
+func (qz QuietZone) ColorModel() color.Model {
+	return qz.barcode.ColorModel()
+}
+
+func Main() {
+  bc, _ := qr.Encode("Foobar", qr.L, qr.Auto)
+
+  var img image.Image = QuietZone{10, bc}
+
+  png.Encode(file, img)
+}
+```
