GS1 Encoding

dBarcode 2D SDK only

If the string member of the BARCODE2D structure begins with an FNC1 character - ASCII 232 (è) - or the DL_DM_GS1 Flag  bit is set, or the AztecMenu property of the Active-X control is set, the string is scanned for GS1 Application Identifiers and encoded according to the GS1 Datamatrix specification.

GS1 encoding requires the Application Identifiers to be provided within brackets, eg. (80)12345678(10)123456 so that the AIs can be identified.

Variable length AIs will have FNC1 characters inserted to terminate the AI and all brackets are removed from the encoded data.

During scanning FNC1 characters are replaced by ASCII values of 29.
