I can generate a UPC code with no problem when I supply the check digit with
the barcode string.
Does iTextSharp supply a check digit if requested? I can see the
GenerateCheckDigit property, but it seems to have no effect when I put it
either before or after like this:
Dim upc As BarcodeEAN = New BarcodeEAN
upc.CodeType = Barcode.UPCA
upc.GenerateChecksum = true
upc.Code = "05117800093"
' or here upc.GenerateChecksum = true
Dim imgUPC = upc.CreateImageWithBarcode(writer.DirectContent,
Color.BLACK, Color.BLACK)
para.Add(New Phrase(New Chunk(imgUPC, 0, 0)))
Also when the checksum is supplied AND it is incorrect, the barcode is
generated anyway. It would probably be better to throw an error in this
case.
Thanks,
Rick
