ZXingCpp 0.5.3

ZXingCpp

ZXingCpp is a high-performance .NET barcode reader and writer powered by zxing-cpp, with a modern API. It supports all major linear and matrix barcode formats like QRCode, DataMatrix, PDF417, EAN/UPC, Code128, etc. It is 5x-50x faster than ZXing.NET, supports more barcode formats (symbologies) and has a higher detection rate on difficult images.

Install

dotnet add package ZXingCpp
dotnet add package SkiaSharp

Read barcodes

SkiaSharp is used here because it works consistently across Windows, Linux, and macOS.

using SkiaSharp;
using ZXingCpp;

var img = SKBitmap.Decode(args[0]).Copy(SKColorType.Gray8);
var iv = new ImageView(img.GetPixels(), img.Info.Width, img.Info.Height, ImageFormat.Lum);

var readBarcodes = new BarcodeReader {
    Formats = args.Length > 1 ? BarcodeFormats.Parse(args[1]) : BarcodeFormat.All,
    TryInvert = false,
    // see the ReaderOptions for more available options
};

foreach (var b in readBarcodes.From(iv))
    Console.WriteLine($"{b.Format}: {b.Text}");

Executing this sample code from the command line would look like this:

dotnet run -- <image-file-name> [barcode-format-list]

Write barcodes

using ZXingCpp;

var barcode = new Barcode(args[1], BarcodeFormat.Parse(args[0]));
File.WriteAllText(args[2], barcode.ToSVG());

Executing this sample code from the command line would look like this:

dotnet run -- <barcode-format> <text> <out-svg-file-name>

Why ZXingCpp

• Fast native-core decoding and encoding (5x-50x faster than ZXing.Net).
• Strong real-world detection performance, especially for QRCode.
• Broad format support (QRCode, DataMatrix, PDF417, EAN/UPC, Code128, and more).
• Standards-compliant binary and ECI handling (bytesECI()).
• Apache-2.0 licensed and free for commercial use (Commercial Support available).

Platform support

The NuGet package includes native libraries for x64 and arm64 on Windows, Linux, and macOS. Version 0.5.3 includes zxing-cpp-v3.1.1

If you need to override native loading, ensure .NET can find [lib]ZXing[.dll|.so|.dylib] (for example via PATH on Windows or LD_LIBRARY_PATH on Linux).
