type
Represents the bar code type. Enter T for standard
EAN 13; enter m for EAN 13 plus a 2-digit add-on
data field; enter n for EAN 13 plus a 5-digit add-on
data field.

ratio
Optional parameter (used in conjunction with 9 or :
above) representing the ratios for variable ratio bar
codes. Default ratios are overridden by the variable
ratio feature. However, unique variable ratios for
EAN 13 bar codes easily generate large, out-of-
spec bar codes. Ratio data must be hexadecimal
numbers from 0 through 9 or A through F; VGL
automatically checks the input for validity. If an
invalid character is found in the ratio, an error
message is generated.

EAN 13 bar codes use eight-digit ratios. The ratios
are interpreted from left to right, measuring the size
of each bar or space, in dot width, in the following
pattern:
