Constructor Detail

EAN13Barcode

public EAN13Barcode(java.lang.String data)
             throws BarcodeException

Constructs a basic mode EAN13 barcode with the specified data and an optional checksum. The length of the barcode is 11, 12 with a checksum. If the length passed is only 11, then a checksum will be automaticaly added. If the length is not 11 or 12 then a barcode exception will be thrown.

Parameters:

data - The data to encode

Throws:

BarcodeException - If the data to be encoded is invalid
