Meziantou.Framework.QRCode.Imaging

Renders the QR codes and barcodes of Meziantou.Framework.QRCode as Meziantou.Framework.Imaging images. The resulting Image<Rgba32> can be saved in any format the library supports (PNG, WebP, JPEG, GIF, AVIF, ...), resized, or drawn onto another image.

Meziantou.Framework.QRCode already writes PNG files on its own (ToPng), with no dependency. Use this package when you need another format or want to process the image further.

Usage

using Meziantou.Framework;
using Meziantou.Framework.Imaging;
using Meziantou.Framework.Imaging.Formats;

var qrCode = QRCode.Create("https://www.meziantou.net", ErrorCorrectionLevel.M);

// Default options: 10 pixels per module, a 4-module quiet zone, black on white
using var image = qrCode.ToImage();
image.Save("qrcode.webp", new WebPEncoder());

// Custom options
using var customImage = qrCode.ToImage(new QRCodeImageOptions
{
    ModuleSize = 4,
    QuietZoneModules = 2,
    DarkColor = new Rgba32(0x00, 0x33, 0x66),
    LightColor = Colors.Transparent,
});

// An indexed PNG stores the two colors in a palette, as ToPng does
customImage.Save("qrcode.png", new PngEncoder { PixelLayout = PngPixelLayout.Indexed });

Barcodes work the same way:

var barcode = Barcode.CreateEan13("5901234123457");
using var image = barcode.ToImage(new BarcodeImageOptions { ModuleWidth = 3, ModuleHeight = 100 });

Drawing a QR code onto an existing image:

using var ticket = Image.Load<Rgba32>("ticket.png");
using var qrCodeImage = QRCode.Create("TICKET-0042").ToImage(new QRCodeImageOptions { ModuleSize = 4 });
ticket.Draw(canvas => canvas.DrawImage(qrCodeImage.Frames[0], new PointD(16, 16)));
ticket.Save("ticket-with-qrcode.png");

Options

QRCodeImageOptions Default Description
ModuleSize 10 Size of each module, in pixels
QuietZoneModules 4 Number of quiet zone modules around the QR code
DarkColor Colors.Black Color of dark modules
LightColor Colors.White Color of light modules and of the quiet zone
BarcodeImageOptions Default Description
ModuleWidth 2 Width of each module, in pixels
ModuleHeight 80 Height of each module, in pixels
QuietZoneModules 10 Number of quiet zone modules on the left and right sides
DarkColor Colors.Black Color of dark modules
LightColor Colors.White Color of light modules and of the quiet zone
