SkiaSharp

SkiaSharp is a cross‑platform 2D graphics API for .NET based on the Skia graphics library. It provides a powerful, hardware‑accelerated rendering engine that integrates seamlessly with game loops, UI frameworks, and custom drawing pipelines.

Introduction

Setup

Drawing Basics

Code Samples

Key features:

High‑performance raster and GPU rendering
Full support for paths, shaders, masks, text layout, and image filters
Works on Windows, macOS, Linux, Android, iOS, and WebAssembly
Open source under the MIT license

Install the NuGet package:

dotnet add package SkiaSharp

For GPU acceleration on Windows, add:

dotnet add package SkiaSharp.NativeAssets.Win32

Initialize in your game loop:

using SkiaSharp;

public class GameRenderer
{
    private SKSurface _surface;
    private SKCanvas Canvas => _surface.Canvas;

    public void Initialize(int width, int height)
    {
        var info = new SKImageInfo(width, height, SKColorType.Rgba8888);
        _surface = SKSurface.Create(info);
    }

    public SKBitmap GetBitmap() => SKBitmap.FromImage(_surface.Snapshot());
}

Basic drawing example:

public void DrawScene(SKCanvas canvas)
{
    canvas.Clear(SKColors.CornflowerBlue);

    using var paint = new SKPaint
    {
        Color = SKColors.OrangeRed,
        IsAntialias = true,
        StrokeWidth = 4,
        Style = SKPaintStyle.Stroke
    };

    // Draw a circle
    canvas.DrawCircle(200, 150, 100, paint);

    // Draw text
    paint.Style = SKPaintStyle.Fill;
    paint.TextSize = 48;
    canvas.DrawText("Hello SkiaSharp!", 100, 300, paint);
}
