SkiaSharp不会用StrokeAndFill填充三角形

Question

我试图绘制并填充一个三角形。我提到了一个android系统-问题如何在android画布上绘制实心三角形并执行以下操作。它绘制三角形，但不填充它。如何填充它？另外，是否可以用不同于线条颜色的颜色填充它？

Xamarin形式

private void OnPainting(object sender, SKPaintSurfaceEventArgs e)
{
        var surface = e.Surface;
        var canvas = surface.Canvas;
        canvas.Clear(SKColors.White);


        var pathStroke2 = new SKPaint
        {
            IsAntialias = true,
            Style = SKPaintStyle.StrokeAndFill,
            Color = new SKColor(244, 0, 110, 200),
            StrokeWidth = 5
        };

        var path2 = new SKPath { FillType = SKPathFillType.EvenOdd };
        path2.MoveTo(0, 0);
        path2.LineTo(0, 140);
        path2.MoveTo(0, 140);
        path2.LineTo(140, 140);
        path2.MoveTo(140, 140);
        path2.LineTo(0, 0);
        path2.Close();
        canvas.DrawPath(path2, pathStroke2);

    }

Answer 1

您不需要同时使用LineTo（）和MoveTo（）-我怀疑这样做会破坏填充算法。相反，只需使用

path2.MoveTo(0, 0);
path2.LineTo(0, 140);
path2.LineTo(140, 140);
path2.LineTo(0, 0);
path2.Close();
