PDF417: 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, p
10
)by17
to get the codeword width.
Multiple the module height (in dots, p
11
) 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.
