Barcoder - Barcode Encoding Library

Lightweight Barcode Encoding Library for .NET Framework, .NET Standard and .NET Core. Additional packages are available for rendering the generated barcode to SVG or an image.

Please note that the image renderer (Barcoder.Renderer.Image) requires .NET6 or .NET8 because of the dependency on SixLabors.ImageSharp.Drawing and no longer works for .NET Framework. However, feel free to create your own renderer with another version or other image generation library.

Code ported from the GO project https://github.com/boombuler/barcode by Florian Sundermann.

var renderer = new SvgRenderer();

using (var stream = new MemoryStream())
using (var reader = new StreamReader(stream))
{

    stream.Position = 0;

    string svg = reader.ReadToEnd();
    Console.WriteLine(svg);
}

Usage - render to PNG, JPEG, GIF or BMP

Example for rendering to PNG:

var barcode = QrEncoder.Encode("Hello World!");
var renderer = new ImageRenderer(new ImageRendererOptions { ImageFormat = ImageFormat.Png });

{
    renderer.Render(barcode, stream);
}
