You have sent the same query four times to the mailing list... Stop hitting
that button :)
PDF417 with alphanumeric content (which base64 hopefully is) has a max of 1800
bytes. Either you find a way to compact your text (before or after encoding)
Or you use a different 2D barcode.
QR has > 4000 alphanum chars
Aztech 3000 chars
Codablock F 2725 chars
Datamatrix 2300 chars
I think at least QR is supported by iText, but check yourself.

Betreff: [iText-questions] Encoding base64 in Barcode
I'm trying to generate a PDF with digital signature. After getting it, I wanted
to add the signature information in base64 to a barcode, but i don't know what
code type have to use. I tested with BarcodePDF417 but I get this error:
Exception in thread "main" java.lang.IndexOutOfBoundsException: The text is too
big.
at com.lowagie.text.pdf.BarcodePDF417.textCompaction (BarcodePDF417.java: 359)
at com.lowagie.text.pdf.BarcodePDF417.assemble (BarcodePDF417.java: 604)
at com.lowagie.text.pdf.BarcodePDF417.paintCode (BarcodePDF417.java: 675)
at com.lowagie.text.pdf.BarcodePDF417.getImage (BarcodePDF417.java: 772)
at firmaPDF.insertaBarCode (firmaPDF.java: 169)
at firmaPDF.main (firmaPDF.java: 61)
The sign has between 1800 and 3000 characters, minimum and maximum. This is the
code I have:
......
PdfReader reader = null;
PdfStamper stamper = null;
try {
reader = new PdfReader (rutaEntrada);
stamper = new PdfStamper (reader, new FileOutputStream
(rutaSalida));
int maxPagina = reader.getNumberOfPages();
PdfContentByte underContent = stamper.getUnderContent (maxPagina);
/ / Insert barcode
BarcodePDF417 BarcodePDF417 codePDF417 = new ();
codePDF417.setText (deskSign.getString ());
Image imageEAN codePDF417.getImage = ();
imageEAN.setAbsolutePosition (100f, 10f);
underContent.addImage (imageEAN);
} Catch .....
Do i have to define something more? Or should I use other encodings?
thanks
