Genocs QRCode Library

Genocs QRCode Library Banner

Encode QR codes as SkiaSharp images, SVG, PNG bytes, and related formats. Optional image decode is included. Supports net10.0, net9.0, and net8.0.

Installation

dotnet add package Genocs.QRCodeLibrary

Getting Started

Use this package to build a QR module matrix with QRCodeGenerator, then render it with a format-specific class (QRCode, SvgQRCode, PngByteQRCode, and others). Payload helpers under PayloadGenerator produce structured strings (Wi-Fi, vCard, Girocode, and more) that you pass into CreateQrCode.

Rendering uses SkiaSharp and does not depend on System.Drawing.Common.

using Genocs.QRCodeLibrary.Encoder;
using SkiaSharp;

using var generator = new QRCodeGenerator();
using QRCodeData data = generator.CreateQrCode("Hello, World!", QRCodeGenerator.ECCLevel.M);
using var qrCode = new QRCode(data);
using SKImage image = qrCode.GetGraphic(20, SKColors.Black, SKColors.White, drawQuietZones: true);

using var stream = File.OpenWrite("qrcode.png");
image.Encode(SKEncodedImageFormat.Png, 100).SaveTo(stream);

To read a QR image, use QRDecoder.ImageDecoder(SKImage). Decode is experimental: crisp generated PNGs are covered by tests; camera-style JPEGs are not a supported path yet.

Avoid the GetGraphic overload that takes an icon or logo overlay.

Main Entry Points

  • QRCodeGenerator
  • QRCode / QRCode.GetGraphic
  • SvgQRCode
  • PngByteQRCode / BitmapByteQRCode / Base64QRCode
  • PayloadGenerator
  • QRDecoder.ImageDecoder

Warning Policy

This package follows the quality gate in build-and-test.yml:

  • Libraries must build for net10.0, net9.0, and net8.0.
  • Unit tests must pass before merging QR encode or decode changes.
