945 (dec) Optional.
or Sets the X dimension of the
module (white or black rectangle)
03 1 (hex)
in 100th of an inch.
Note: Values that go beyond the
defined range will be appropriately
clipped and set to the minimum
and maximum values.
To set the X dimension to default
at 600 dpi requires a value of 9.45,
which is specified as 945 (dec) or
03 B1 (hex).
The Units enumeration would be
set to 02 (hex) (or 00 (hex)), and
these two bytes would be 03 (hex)
and B1 (hex).
1890 (dec) Optional.
or Note: The range of values of the
Ydimension is between 2 to 5
07 62 (hex)
times the values of the
X-dimension. Any value beyond
that range will be clipped
appropriately and set to the
minimum and maximum values.
Sets the Y dimension of the
module (white or black rectangle)
in 100th of an inch.
The default width of this element
from the bar code engine is twice
that of the X-dimension. To set the
Y-dimension to default at 600 dpi
requires a value of 18.9, which is
specified as 1890 (dec) or 07 62
(hex).
The Units enumeration would be
set to 02 (hex) (or 00 (hex)), and
these two bytes would be 07 (hex)
and 62 (hex). If not specified, the Y
dimension will become double that
of the X-dimension.
0 (dec) Optional.
