Members

Value	Member	Description
0	Unknown	Unknown symbology type. This has a special meaning in some of the methods that use BarcodeSymbology. For example, you can pass Unknown as the symbology parameter for the BarcodeReader.ReadBarcode method to indicate that the barcode type is unknown. It will also instruct the engine to read the first barcode found in the image using the other parameters.
1	EAN13	EAN-13 (International Article Number with 13 digits) symbology. Used internationally with consumer products.
2	EAN8	EAN-8. Derived from the longer European Article Number (EAN-13) code. It was introduced for use on small packages where an EAN-13 barcode would be too large.
3	UPCA	UPC-A (Universal Product Code). Used with consumer products in the United States.
4	UPCE	UPC-E. The short version of UPC-A.
5	Code3Of9	Code 3 of 9 (Code 39) type. Used especially in non-retail environments.
6	Code128	Code 128 type. Very dense code, used extensively worldwide.
7	CodeInterleaved2Of5	Interleaved 2 of 5 type. Used in warehouse, industrial applications.
8	Codabar	CODABAR (Ames Code/USD-4/NW-7/2 of 7 Code) type. Used in libraries and blood banks.
9	UCCEAN128	UCCEAND 128 type
10	Code93	Code 93 type. Compressed form of Code 39
11	EANEXT5	5-digit supplemental type. May be used with UPCA, UPCE, EAN13 and EAN8 on books to indicate a suggested retail price.
12	EANEXT2	2-digit supplemental type. May be used with UPCA, UPCE, EAN13 and EAN8 to indicate magazines and newspaper issue numbers.
13	MSI	MSI (Modified Plessey) type. Used to mark retail shelves for inventory control.
14	Code11	Code 11 (USD-8) type. Used in labeling telecommunications equipment.
15	CodeStandard2Of5	Standard 2 of 5 (Industrial 2 of 5) type. Used in the photofinishing, warehouse sorting industries and sequentially numbering airline tickets.
16	GS1Databar	GS1 Databar (formerly RSS14) type. Used in grocery industry, healthcare, and where items are too small to allow for older barcode symbologies.
17	GS1DatabarLimited	GS1 Databar (formerly RSS14) Limited type. It is a short version of GS1 Databar (formerly RSS14).
18	GS1DatabarExpanded	GS1 Databar (formerly RSS14) Expanded type. It encodes item identification plus supplementary strings such as weight and date. Used in grocery industry and healthcare.
19	PatchCode	Patch Code type. Used only for batch separation and scanner control, primarily with Kodak scanners.
20	PostNet	POSTNET (Postal Numeric Encoding Technique). Used by the United States Postal Service to assist in directing mail.
21	Planet	PLANET (Postal Alpha Numeric Encoding Technique). Used by the United States Postal Service to identify and track pieces of mail during delivery.
22	AustralianPost4State	Australian Post 4-State type.
23	RoyalMail4State	Royal Mail (RM4SCC) 4-State type.
24	USPS4State	USPS OneCode 4-State Barcode (4BC) type.
25	GS1DatabarStacked	GS1 Databar (formerly RSS14) Stacked / GS1 Databar Stacked Omni-Directional types. Used as GS1 Databar when the available space is too narrow for the standard GS1 Databar.
26	GS1DatabarExpandedStacked	GS1 Databar (formerly RSS14) Expanded Stacked barcode type. Used as GS1 Databar Expanded when the available space is too narrow to fit in one line.
27	PDF417	PDF417 (Portable Data File). 2D symbol used in a variety of applications, primarily transport, identification cards, and inventory management. Note, the PDF417 barcode symbology does not have any relation to Adobe PDF (Portable Document Format).
28	MicroPDF417	MicroPDF417 (Portable Data File). Version of PDF417 that can hold up to 150 bytes of data. Note, the MicroPDF417 barcode symbology does not have any relation to Adobe PDF (Portable Document Format).
29	Datamatrix	Datamatrix. 2D symbol code used for marking small items.
30	QR	QR (short for Quick Response). 2D symbol used by dedicated QR barcode readers and camera phones.
31	Aztec	Aztec. 2D symbol used for train tickets, airline tickets and government documents. This barcode is able to reduce the required space over other matrix barcode as it does not require a surrounding quiet zone.
32	Maxi	MaxiCode. 2D symbol developed and used by the United Parcel Service to identify and track pieces of mail during delivery.
33	MicroQR	Micro QR. 2D symbol used where symbol size is limited. There are four sizes; the largest is capable of encoding 35 characters. Some sizes support more than one error correction level.
34	PharmaCode	PharmaCode type. Used in the pharmaceutical industry as a packing control system.

Remarks

To get a list of all the barcode symbologies supported by LEADTOOLS, use BarcodeEngine.GetSupportedSymbologies, to get a list of the read or write symbologies currently available (support has been unlocked and the backend runtime assembly exists), use BarcodeReader.GetAvailableSymbologies and BarcodeWriter.GetAvailableSymbologies.

For description and visual samples of the barcode symbologies supported by LEADTOOLS, refer to Supported Barcode Symbologies.

The BarcodeEngine.GetSymbologyFriendlyName method can be used to return a string that contains a friendly name for any BarcodeSymbology enumeration member.
