specifying a box, horizontal whitespace is usually required in order to create a
quiet zone between the barcode and the sides of the box.
For linear symbols, horizontal boundary bars appear tight against the barcode,
inside any vertical whitespace (or text). For matrix symbols, however, where
they are decorative rather than functional, boundary bars appear outside any
whitespace.
