Lyo.QRCode.QRCoder 3.0.0

Lyo.QRCode.QRCoder

IQRCodeService from Lyo.QRCode implemented with QRCoder. Pick this for JPEG / Bitmap on Windows or for QRCoder's renderers. BuiltInQRCodeService is the in-library ISO encoder with no extra NuGet.

Examples

Generate with QRCoder

using Lyo.QRCode;
using Lyo.QRCode.Models;
using Lyo.QRCode.QRCoder;
using Microsoft.Extensions.DependencyInjection;

var services = new ServiceCollection();
services.AddQRCoderQrCodeService(o => {
    o.DefaultSize = 16; // pixels per module
    o.DefaultFormat = QRCodeFormat.Png; // Jpeg / Bmp also supported via QRCoder
    o.DefaultErrorCorrectionLevel = QRCodeErrorCorrectionLevel.Medium;
});

var qr = services.BuildServiceProvider().GetRequiredService<IQRCodeService>();
var result = await qr.GenerateAsync("https://example.com");

Bind options from configuration

services.AddQRCoderQrCodeServiceFromConfiguration(builder.Configuration);

appsettings sample

{
  "QRCodeService": {
    "DefaultSize": 16,
    "DefaultFormat": "Png",
    "DefaultErrorCorrectionLevel": "Medium",
    "MinSize": 1,
    "MaxSize": 2000,
    "EnableMetrics": false
  }
}

Types

Platform and decoration

• JPEG / Bitmap go through System.Drawing and run on Windows. PNG/SVG paths are cross-platform.
• ReadFromImageAsync decoding uses QRCodeZxingRead in this package (ZXing.Net + ImageSharp), matching the built-in service.
• Decoration is out of scope. Center logos and frames are no longer applied by the QRCoder service. Send the returned bytes through Lyo.Images.IImageDecorationService.Pipeline(...) and call Overlay / AddFrame / AddCaption / AddOuterPadding as needed (see the Lyo.Images README).
