Adding a .NET MAUI SignaturePad reference

Syncfusion .NET MAUI controls are available in Nuget.org. To add .NET MAUI SignaturePad control to your project, open the NuGet package manager in Visual Studio, search for Syncfusion.Maui.SignaturePad and then install it.

Step 1: Create a .NET MAUI application project in Visual Studio 2022.

Step 2: Add the Syncfusion.Maui.Core Nuget to the project from nuget.org.

Step 3: In the MauiProgram.cs file, register the Syncfusion.Maui.Core handler as follows.

C#

using Syncfusion.Maui.Core.Hosting;
namespace SignaturePad;
public static class MauiProgram
{
    public static MauiApp CreateMauiApp()
    {
        var builder = MauiApp.CreateBuilder();
        builder
            .UseMauiApp<App>()
            .ConfigureSyncfusionCore()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
            });
        return builder.Build();
    }
}

Features and Benefits

Customization

The appearance of the .NET Maui SignaturePad is highly customizable.

Realistic, handwritten signature look and feel

The unique stroke rendering algorithm draws a signature based on the speed of the gesture drawing along with minimum and maximum stroke thicknesses, which gives a realistic handwritten look and feel to the signature.

Save signatures as images

Save the drawn signature as an image. This converted image can be embedded in documents, PDFs, and anything else that supports using images to denote a signature.

Events

Events occur whenever you start and finish drawing in the SignaturePad.
