PDF417: General
Information
A PDF417 symbol is organized into minimum
of 3 to a max imum of 90 rows and a minimum
of 5 to a max imum of 34 col umns of
codewords.
Each code word is 17 mod ules wide. There are 4
bars and 4 spaces per code word.
Multiply the module width (in dots,
p
10
) by 17
to get the codeword width.
Multiple the mod ule 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 in dicators. The re maining
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
columns would pro duce a data re gion of 2700
codewords which ex ceeds the 928 code word
maximum per sym bol. See the fol lowing table
(on the next page) that shows the maximum
number of rows and the resulting num ber of
codewords in the data re gion for each col umn
count.
