QR Code Generation

CodeGlyphX provides comprehensive QR code support including standard QR and Micro QR formats.

Basic Usage

using CodeGlyphX;

// Simple one-liner
QR.Save("https://example.com", "qr.png");

// With error correction level
QR.Save("https://example.com", "qr.png", QrErrorCorrection.H);

Error Correction Levels

Level	Recovery	Use Case
`L`	~7%	Maximum data capacity
`M`	~15%	Default, balanced
`Q`	~25%	Higher reliability
`H`	~30%	Maximum error correction

Styling Options

using CodeGlyphX;

var options = new QrEasyOptions
{
    ModuleShape = QrPngModuleShape.Rounded,
    ModuleCornerRadiusPx = 3,
    Eyes = new QrPngEyeOptions
    {
        UseFrame = true,
        OuterShape = QrPngModuleShape.Circle,
        InnerShape = QrPngModuleShape.Circle,
        OuterColor = new Rgba32(220, 20, 60),
        InnerColor = new Rgba32(220, 20, 60)
    }
};

QR.Save("https://example.com", "styled-qr.png", options);

Fluent Builder (logo + styling)

using CodeGlyphX;
using CodeGlyphX.Rendering;

var logo = LogoBuilder.CreateCirclePng(
    size: 96,
    color: new Rgba32(24, 24, 24),
    accent: new Rgba32(240, 240, 240),
    out _,
    out _);

var png = QR.Create("https://example.com")
    .WithLogoPng(logo)
    .WithLogoScale(0.22)
    .WithLogoPaddingPx(6)
    .WithStyle(QrRenderStyle.Fancy)
    .Png();

Style Board Presets (Homepage Gallery)

The homepage style board is generated from a curated set of presets. Each QR payload points back to this section and includes a ?style=slug hint for tracking or future deep-linking. All presets use error correction H, a 384px target size, and a quiet zone of 4 modules to keep them crisp while remaining web-friendly.

Full source code for these presets lives in QrStyleBoardExample.cs.
