Decode FNC Symbols

The GS1 association utilizes FNC symbols to manage decoding for Code 128 and some other barcode types. There are four types of FNC symbols (FNC1-4) among which FNC1 is the most widespread one and is used for GS1 Application Identifier (AI) marking. When the library detects that a barcode does not correspond to any of GS1 types (e.g. Code 128 or GS1 Code 128), the decoder outputs FNC symbols as “<FNC#>”. Such messages can be deleted from the recognition results by setting the StripFNC property to false.
