如何在 Xamarin 应用程序中构建斜虚线

How can I build slanted dashed line in Xamarin application

我想在我的应用程序中显示一条斜虚线,看起来像 this。在 xamarin 中使用 Line API 我能够创建虚线,但我没有任何运气使每个破折号倾斜。我还查看了 Xamarin 的 skiasharp 库,但没有找到任何可以帮助倾斜的东西。

@jason 感谢您的回复,我非常专注于获得您建议的“倾斜虚线”,但我从来没有想过。虽然现在我的问题有了解决方案。

public partial class SlantedDashedView : ContentView
{
    private readonly SKPaint paint = new SKPaint
    {
        Style = SKPaintStyle.Fill,
        Color = Color.Red.ToSKColor()
    };

    private readonly SKRect rect = new SKRect
    {
        Location = new SKPoint(0, 0),
        Size = new SKSize(25, 30)
    };

    public SlantedDashedView()
    {
        InitializeComponent();
        mainCanvas.InvalidateSurface();
    }

    private void MainCanvas_PaintSurface(object sender, SKPaintSurfaceEventArgs e)
    {
        SKImageInfo info = e.Info;
        SKSurface surface = e.Surface;
        SKCanvas canvas = surface.Canvas;

        int currentY = 0;
        canvas.Skew(0, -1);
        while (currentY < info.Height)
        {
            canvas.DrawRect(rect, paint);
            currentY += 45;
            canvas.Translate(0, 45);
        }
    }
}

Here是结果
