PDF417: General
Information
A PDF417 sym bol is or ga nized into min i mum
of 3 to a max i mum of 90 rows and a min i mum
of 5 to a max i mum of 34 col umns of
codewords.
Each code word is 17 mod ules wide. There are 4
bars and 4 spaces per code word.
Mul ti ply the mod ule width (in dots, p
10
) by 17
to get the code word width.
Mul ti ple the mod ule height (in dots, p
11
) by the
num ber of rows to get the sym bol height.
Four of the codewords in each row are start,
stop and two row in di ca tors. The re main ing
codewords are re ferred to as the data re gion
and con tain sym bol over head and com pacted
data.
There can be no more than 928 codewords in
the data re gion. All com bi na tions of rows
and col umns are not le gal; 90 rows times 30
col umns would pro duce a data re gion of 2700
codewords which ex ceeds the 928 code word
max i mum per sym bol. See the fol low ing ta ble
(on the next page) that shows the max i mum
num ber of rows and the re sult ing num ber of
