QrCodeGenerator

Cross plafrom C# Qr code image generator

Simple wrapper around:

https://github.com/manuelbl/QrCodeGenerator

Advantages

• Select Driver even on runtime
• Robustness in case on some platforms, some drawing libraries are having problems
• Modern Fluent API initialization (surely improvable)
• Added ready to use Payloads (allows generation of specific QrCodes)
• You can expand easily to support more advanced features exposed by original Library
• Added usage sample in Blazor

Example Syntax

var qr = new QrDrawerFactory().GetDriver(DrawDriverType.SkiaSharp)
                .SetQr("Hello World")
                .SetImageFormat(CommonImageFormat.Png)
                .GetBytes();

//------------------------------------------------------------------------------------

var msg = new PayloadGenerator.ContactData(
                PayloadGenerator.ContactData.ContactOutputType.VCard4,
                "Name",
                "Surname",
                "EvilMax"
                ).ToString();

var qr2 = new QrDrawerFactory().GetDriver(DrawDriverType.ImageSharp)
                .SetQr(msg)
                .SetImageFormat(CommonImageFormat.Png)
                .Save("./Test.png");
