Aprillz.MewUI.Skia

Skia (SkiaSharp) rendering integration for MewUI. Provides a SkiaCanvasView control so you can draw with SkiaSharp inside a MewUI window, plus the ISkiaInteropProvider registry.

  • Ships a CPU upload fallback that works on any MewUI backend out of the box.
  • Install a matching Aprillz.MewUI.Skia.Interop.* package for a zero-copy GPU path on your backend.

Install

dotnet add package Aprillz.MewUI.Skia

Then add the interop package for the backend you run on (optional - without it, the CPU fallback is used):

Interop package Backend Activate at startup
Aprillz.MewUI.Skia.Interop.Direct2D Direct2D (Windows) SkiaDirect2DInterop.Use()
Aprillz.MewUI.Skia.Interop.Gdi GDI (Windows) SkiaGdiInterop.Register()
Aprillz.MewUI.Skia.Interop.MewVG.Win32 MewVG / Win32 SkiaMewVGWin32Interop.Use()
Aprillz.MewUI.Skia.Interop.MewVG.X11 MewVG / X11 (Linux) SkiaMewVGX11Interop.Use()
Aprillz.MewUI.Skia.Interop.MewVG.MacOS MewVG / macOS SkiaMewVGMacOSInterop.Use()

Each interop bridges Skia and that backend so the Skia surface is consumed without a per-frame copy. Register it once at startup, after the backend is registered; if no interop is registered, SkiaCanvasView falls back to a CPU upload (correct, just not zero-copy).

Usage

// startup: register your backend, then (optionally) the matching Skia interop
Direct2DBackend.Register();
SkiaDirect2DInterop.Use();

// draw with SkiaSharp inside MewUI
var canvas = new SkiaCanvasView();
canvas.PaintSurface += (s, e) =>
{
    var c = e.Surface.Canvas;
    c.Clear(SKColors.Transparent);
    using var paint = new SKPaint { Color = SKColors.MediumPurple, IsAntialias = true };
    c.DrawCircle(e.Info.Width / 2f, e.Info.Height / 2f, 40, paint);
};

Packages in this family

  • Aprillz.MewUI.Skia (this package) - SkiaCanvasView, the interop registry, and the CPU fallback.
  • Aprillz.MewUI.Skia.Interop.* - per-backend zero-copy GPU bridges (table above).
  • Aprillz.MewUI.Skia.{Windows,Linux,MacOS,All} - metapackages bundling the core + the interops for a platform.
