DRIT.Barcode

Pure-Managed .NET Barcode Generation and Recognition Library

Generate and Recognize 60+ Barcode Symbologies with Vector SVG/EMF Output

DRIT.Barcode is a pure-managed .NET library for generating and recognizing barcodes across 60+ symbologies — 1D linear, 2D matrix, GS1 DataBar, postal, and complex barcodes — with all encoding and decoding algorithms implemented from scratch. Rendering is powered by DRIT.Drawing, so any barcode can be emitted as raster (PNG, JPEG, BMP, GIF, TIFF) or true vector (SVG, EMF) output, with no embedded rasters.

Key Benefits

• Zero external barcode dependencies – all symbology engines and the recognition pipeline are implemented in source
• 60+ symbologies – 1D, 2D, GS1 DataBar, postal, and complex barcodes (Swiss QR Bill, HIBC, Mailmark)
• Generation and recognition – BarcodeGenerator produces images; BarCodeReader decodes from images with quality presets
• True vector output – SVG and EMF with vector bar geometry, not embedded rasters
• GS1-first – Application Identifier parsing, GS1-128, GS1 DataMatrix, GS1 QR, and GS1 Composite Bar
• Familiar API – follows established .NET barcode library conventions, easy to pick up

Cross-Platform Barcode Library

DRIT.Barcode targets .NET 8.0, so it runs on:

• Operating Systems: Windows, Linux, macOS
• Frameworks: .NET 8.0+
• Dependencies: DRIT.Drawing (rendering + codecs), DRIT.Pdf (PDF output)

• Inverted-image recognition – detect white-on-black barcodes
• Checksum validation and GS1/HIBC text formatting on decoded results

GS1 Support

Full GS1 Application Identifier handling on both generation and recognition:

• Parse parentheses/bracket notation into FNC1-separated raw codetext
• Format decoded GS1 data back to human-readable parentheses notation
• GS1-128, GS1 DataMatrix, GS1 QR, and GS1 Composite Bar symbologies

Visual Customization

Control every aspect of barcode appearance:

• Bar and background colors
• Code text font, size, placement (above/below/none), and alignment
• Captions above and below the barcode
• Borders with dash styles, width, and color
• Padding, rotation angle, resolution (DPI)
• X-dimension, bar height, bar width reduction
• Auto-sizing modes (Nearest, Interpolation)

Output Formats

Code Examples

Generate a Barcode

using DRIT.Barcode;
using DRIT.Barcode.Generation;

// Create a barcode generator for Code 128
using var gen = new BarcodeGenerator(EncodeTypes.Code128, "DRIT.Barcode");

// Configure bar dimensions
gen.Parameters.Barcode.XDimension.Pixels = 2f;
gen.Parameters.Barcode.BarHeight.Pixels = 80f;

// Save as PNG
gen.Save("barcode.png", BarCodeImageFormat.Png);

Recognize Barcodes

using DRIT.Barcode;
using DRIT.Barcode.Recognition;

// Create a reader for Code 128
using var reader = new BarCodeReader("barcode.png", DecodeType.Code128);

// Read all barcodes in the image
BarCodeResult[] results = reader.ReadBarCodes();

foreach (BarCodeResult result in results)
{
    Console.WriteLine("Type:   {0}", result.CodeTypeName);
    Console.WriteLine("Text:   {0}", result.CodeText);
}

Generate to Vector SVG and EMF

using DRIT.Barcode;
using DRIT.Barcode.Generation;

// Any barcode can be emitted as true vector output
using var gen = new BarcodeGenerator(EncodeTypes.QR, "https://github.com/dritsoftware/DRIT.Barcode");
gen.Parameters.Barcode.XDimension.Pixels = 4f;

// True vector — bars are drawn as vector rectangles, not embedded rasters
gen.Save("qr.svg", BarCodeImageFormat.Svg);
gen.Save("qr.emf", BarCodeImageFormat.Emf);

GS1 Barcodes

using DRIT.Barcode;
using DRIT.Barcode.Generation;

// GS1-128 with Application Identifiers in parentheses notation
using var gen = new BarcodeGenerator(
    EncodeTypes.GS1Code128, "(01)12345678901231(10)LOT123(17)251231");
gen.Save("gs1-128.png", BarCodeImageFormat.Png);

// GS1 DataMatrix
using var dm = new BarcodeGenerator(
    EncodeTypes.GS1DataMatrix, "(01)04212345678905(11)250101");
dm.Save("gs1-dm.png", BarCodeImageFormat.Png);
