SKCanvas.DrawCircle() 正在绘制正方形

Question

我使用 OpenGL 在 .NetCore 中设置 SkiaSharp。如果我调用 DrawCircle() 函数，它会呈现正方形，这看起来很奇怪。我的代码如下所示：

using (SKPaint paint = new SKPaint {
    Style = SKPaintStyle.Stroke,
    Color = SKColors.Red,
    StrokeWidth = 25,
}) {
    canvas.RotateDegrees( 2 );
    canvas.DrawCircle( info.Width / 2, info.Height / 2, 100, paint );
    paint.Style = SKPaintStyle.Fill;
    paint.Color = SKColors.Blue;
    canvas.DrawCircle( info.Width / 2, info.Height / 2, 75, paint );

    canvas.RotateDegrees( 20 );
    canvas.DrawCircle( info.Width / 2, info.Height / 2, 50, paint );
    paint.Style = SKPaintStyle.Fill;
    paint.Color = SKColors.Yellow;
    canvas.DrawCircle( info.Width / 2, info.Height / 2, 25, paint );

}

然后屏幕看起来像这样：

为什么会有正方形？

Answer 1

所以我不小心通过添加抗锯齿解决了这个问题。

using (SKPaint paint = new SKPaint {
     ...,
     ...,
     IsAntialias = true
}) {
     ...
}
