PDF 417: General Information
A PDF417 symbol is organized into minimum of 3 to a maximum of 90 rows and a minimum
of 5 to a maximum of 34 columns of codewords.
Each codeword is 17 modules wide. There are 4 bars and 4 spaces per codeword.
Multiply the module width (in dots, p10) by 17 to get the codeword width.
Multiply the module height (in dots, p11) by the number of rows to get the symbol height.
Four of the codewords in each row are start, stop and two row indicators. The remaining
codewords are referred to as the data region and contain symbol overhead and compacted data.
There can be no more than 928 codewords in the data region. All combinations of rows and
columns are not legal; 90 rows times 30 columns would produce a data region of 2700
codewords which exceeds the 928 codeword maximum per symbol. See the following table
(on the next page) that shows the maximum number of rows and the resulting number of
codewords in the data region for each column count.

(o) = rotation Accepted Values:
0 = 0º
1 = 90º
2 = 180º
3 = 270º
Settings of 90° & 270° will cause the symbols maximum
height (
p
4
) andwidth (p
5
) values to transpose when
automatically calculating and generating the symbol, i.e.
the height would affect column dimensions and width
would affect row dimensions.
“DATA” = ASCII data or
binary data bytes
Represents a fixed data field.
The backslash (\) character designates the following character
is a literal and will encode into the data field.
