Barcode generation library with SVG and PNG renderers. Implements the Barcode specification from scratch with support for Code 39 / Code 128 linear barcodes.

Supported Barcode Types

Type	Method	Description
Code 39	Barcode.CreateCode39(...)	Supports standard Code 39 alphabet, optional Mod 43 checksum
Code 93	Barcode.CreateCode93(...)	Supports standard and extended Code 93 character encoding
Code 128	Barcode.CreateCode128(...)	Supports Code Set B and automatic switching to Code Set C for numeric runs
EAN-8	Barcode.CreateEan8(...)	Supports 7/8-digit payloads and optional 2/5-digit add-on extension
EAN-13	Barcode.CreateEan13(...)	Supports 12/13-digit payloads and optional 2/5-digit add-on extension
UPC-A	Barcode.CreateUpcA(...)	Supports 11/12-digit payloads and optional 2/5-digit add-on extension
Codabar	Barcode.CreateCodabar(...)	Supports standard Codabar payload characters and configurable start/stop guards
ITF	Barcode.CreateItf(...)	Supports numeric payloads with an even number of digits

Usage

Generate barcodes (Code 39, Code 93, Code 128, EAN/UPC, Codabar, ITF)

var code39 = Barcode.CreateCode39("ABC-123", includeChecksum: true);
var code93 = Barcode.CreateCode93("ABC123");
var code128 = Barcode.CreateCode128("SKU-123456");
var ean8 = Barcode.CreateEan8("5512345");
var ean13 = Barcode.CreateEan13("400638133393");
var upcA = Barcode.CreateUpcA("03600029145", extension: "12");
var codabar = Barcode.CreateCodabar("40156", startCharacter: 'A', stopCharacter: 'B');
var itf = Barcode.CreateItf("12345678");

Console.WriteLine($"{code39.Type} {code39.Width}x{code39.Height}");
Console.WriteLine($"{code93.Type} {code93.Width}x{code93.Height}");
Console.WriteLine($"{code128.Type} {code128.Width}x{code128.Height}");
Console.WriteLine($"{ean8.Type} {ean8.Width}x{ean8.Height}");
Console.WriteLine($"{ean13.Type} {ean13.Width}x{ean13.Height}");
Console.WriteLine($"{upcA.Type} {upcA.Width}x{upcA.Height}");
Console.WriteLine($"{codabar.Type} {codabar.Width}x{codabar.Height}");
Console.WriteLine($"{itf.Type} {itf.Width}x{itf.Height}");

Render as SVG

var barcodeSvg = code128.ToSvg(new BarcodeSvgOptions
{
    ModuleWidth = 2,
    ModuleHeight = 80,
    QuietZoneModules = 10,
});

Logo images are currently supported in the SVG renderer only.

Render as PNG

var barcodePng = code39.ToPng(new BarcodePngOptions
{
    ModuleWidth = 2,
    ModuleHeight = 80,
    DarkColor = Color.FromRgb(0x0f, 0x76, 0x6e),
    LightColor = Color.FromRgb(0xec, 0xfe, 0xff),
});
File.WriteAllBytes("barcode.png", barcodePng);
