Range of d is 0 to F (0 to 15 dots).

When defining a variable width bar code, first choose a bar code type that matches the desired bar code. Then specify the width of the bars and spaces to achieve the desired bar code density and wide:narrow ratios.
Example:
Bar code type “a” defines a rather dense Code 39 bar code with 1:1:2:2 ratio.
