(TBarcode1D_Code128, TBarcode1D_EAN128)
Specifies whether direct encoding of GS1 barcode text is allowed.
property AllowGS1: Boolean;
The Code-128 and EAN-128 barcode symbology can be used to encode a GS1 barcode text. If the property is set to True, you can use the GS1 barcode text directly as the value for the Barcode or Data property, and as the value for the Barcode or Data parameter in the DrawTo, DrawToSize, Print, and PrintSize methods.
Note, in GS1 barcode text, parentheses "()" should be used to enclose Application Identifiers (AIs), and '((' should be used to insert a '(' character; the FNC1 is inserted automatically, there is no need to insert it manually. for example: '(01)00625251888886(18)110201(10)456((D)CB(21)9876543210'.
