I need to store 1772 bytes of data into a PDF417 codebar, but when I
try to generate the pdf I get the error:
java.lang.IndexOutOfBoundsException: The text is too big.
at com.lowagie.text.pdf.BarcodePDF417.textCompaction(Unknown
Source)
at com.lowagie.text.pdf.BarcodePDF417.assemble(Unknown Source)

at pdf417.PDF417iText.main(PDF417iText.java:77)
In http://www.pdf417.com is written that the maximum capacity is one
kilobyte of data per label, but doing tests I succeeded storing up to
1197 bytes. I also read in the same page that using text compaction mode
you can go up to 1850 caracters, but I don't know how to select
compaction mode. I read on this list that you don't need to set it, that
it's automatic. My data is codified in b64, so I understand that you can
use text compaction mode.
I also read that the number of columns can be from 1 to 30, but I can
only get 18 columns generating a 1197 bytes data PDF. How can I generate
a bigger barcode?
How much is the maximum capacity that you can store in a label? What
can I do if I need to store more than the maximum? (for example 5Kb)
Using more than one label?
Thanx in advance,
Jorge Cambra
