c# - SciChart FastLineRenderableSeries 抗锯齿不起作用

Question

我已尝试在折线图(实时 FIFO)上将 AntiAliasing 设置为 true，但它似乎不起作用。还有什么我需要做的吗？

这是 XAML...

<s:SciChartSurface x:Name="sciChart" Grid.Column="1" GridLinesPanelStyle="{StaticResource GridLinesPanelStyle}" RenderTransformOrigin="0.498,0.48" RenderableSeries="{Binding ChartSeries}">

以及背后的代码......

    private void AddCurveToChart(XyDataSeries<double, double> curveSeries)
    {

        FastLineRenderableSeries renderableCurve = new FastLineRenderableSeries
        {
            DataSeries = curveSeries,
            Stroke = (Color)ColorConverter.ConvertFromString(Strokes[ChartSeries.Count < Strokes.Length ? ChartSeries.Count : Strokes.Length - 1]),
            StrokeThickness = 2,
            AntiAliasing = true,

        };

        ChartSeries.Add(renderableCurve);

        RaisePropertiesChanged("ChartSeries");
    }

但是，正如您从屏幕截图中看到的那样，我仍然遇到“锯齿”......

根据 SciChart您需要使用高质量、DirectX 或矢量渲染器插件之一才能获得抗锯齿线。他们将您引导至此 article有关插件的更多信息。

• The HighSpeedRenderSurface An integer coordinate, fast, software renderer (CPU Based). Produces jagged lines but it's very quick.

• The HighQualityRenderSurface (Available in the Pro and Source Editions) A floating point coordinate software renderer (CPU Based).
  Produces the best quality image, but uses more CPU resources than
  HighSpeed.

• The Direct3D10RenderSurface (Available in the Source Edition) A floating point, DirectX10 hardware renderer (GPU Based). Utilizes
  pixel shaders to offload as much computation to the GPU as possible.

HighSpeedRenderSurface 默认使用，它会产生锯齿状的线条。

要启用 HighQualityRenderSurface(仅在专业版中可用):

<s:SciChartSurface>
   <s:SciChartSurface.RenderSurface>
      <s:HighQualityRenderSurface/>
   </s:SciChartSurface.RenderSurface>
</s:SciChartSurface>

Direct3D10RenderSurface 可以这样使用(仅在“源代码版”中可用):

<s:SciChartSurface.RenderSurface>
    <s3D:Direct3D10RenderSurface InitializationFailed="OnDirectXInitializationFailed"
                                 RenderingFailed="OnDirectXRenderingFailed"/>
</s:SciChartSurface.RenderSurface>
