Use the
#b1, #b2
parameters to specify the desired number of rows and columns. You can also use the
#s1,
#s2
parameters to specify the aspect ratio that you want. Use only one technique. If both types of parameters
appear in a bar code selection escape sequence, then use the type appearing last in the sequence to select the
symbol size.
† Aspect ratio values are used if the
#b
parameter is not used to set rows and columns manually.
‡ The default value
0
sets the symbol to the necessary size to capture the encoding data. The optional value
1
uses
the values in parameters
#1
and
#2
to set a mandatory symbol size, while holding a fewer amount of data. The
symbol size is larger than necessary for the encoding data.
In printing PDF417 symbols, the parameter values sent using this technique follow the same rules for parameter
values sent when using the Transfer Bar Code Descriptor.
In relation to the fields of the Lexmark bar code descriptor for PDF417, the following correspondences exist
when using this technique:
