EAN13
Calculates the European Article Number (EAN) barcoding standard to the supplied variable parameter.
SpecName (constant) The variable containing the input to be converted. Proper EAN13 font must be applied in the template.
ErrorMessage (multiple | optional) The error message to return when any error occurs.
This method follows the specifications of the European Article Number (EAN), which is a subset of the original 12-digit UPC system developed in North America. The EAN-13 barcode is defined by the standards organization GS1.
