在Xamarin.Forms上用SkiaSharp库绘制样条曲线(平滑路径)？

<skia:SKCanvasView x:Name="canvasView" PaintSurface="OnCanvasViewPaintSurface" />

private void OnCanvasViewPaintSurface(object sender, SKPaintSurfaceEventArgs e)
{
    SKSurface surface = e.Surface;
    SKCanvas canvas = surface.Canvas;

    // 清空画布
    canvas.Clear(SKColors.White);

    // 创建路径对象
    SKPath path = new SKPath();

    // 添加曲线点
    path.MoveTo(100, 100);
    path.CubicTo(150, 50, 250, 150, 300, 100);

    // 创建画笔对象
    SKPaint paint = new SKPaint
    {
        Style = SKPaintStyle.Stroke,
        Color = SKColors.Black,
        StrokeWidth = 2
    };

    // 绘制曲线
    canvas.DrawPath(path, paint);
}
