UpcESymbology Class
Represents a barcode symbology implementation for UPC-E.
public class UpcESymbology : EanUpcSymbologyBase- Inheritance:
- object ObservableObjectBase BarcodeSymbologyBase LinearBarcodeSymbologyBase EanUpcSymbologyBase object
Remarks
UPC-E is a compressed (zero-suppressed) version of UPC-A designed for use on small packages. It encodes an 8-digit number (including the number system digit and check digit) that can be expanded back to a full 12-digit UPC-A code.
The value provided should be either a 6-digit compressed code (number system and check digit are determined
automatically), a 7-digit code (with number system prefix; check digit is auto-calculated),
or an 8-digit code (with number system prefix and check digit, which is validated).
Only digits 0-9 are supported.
The number system digit must be 0 or 1.
UPC-E encoding uses 6 digits with variable parity (based on the check digit) between two guard patterns. There is no center guard pattern in UPC-E.
This symbology supports optional 2-digit and 5-digit add-on supplements via a supplement value in the encoding request.
