wpf - 将 TextOptions.TextFormattingMode 与 FormattedText 结合使用

Question

使用 WPF4，您可以通过将 TextOptions.TextFormattingMode="Display"和 TextOptions.TextRenderingMode="Aliased"添加到 xaml 来获得非模糊文本:

<Window
   TextOptions.TextFormattingMode="Display"
   TextOptions.TextRenderingMode="Aliased">

这对我来说效果很好，除了当我使用 DrawingContext.DrawText 绘制文本时，如下所示:

void DrawText(DrawingContext dc)
{
  FormattedText ft = new FormattedText("Hello World",
    System.Globalization.CultureInfo.CurrentCulture,
    System.Windows.FlowDirection.LeftToRight,
    new Typeface(FontFamily, FontStyle, FontWeight, FontStretch),
    FontSize,
    brush);
  dc.DrawText(ft, new Point(rect.Left, rect.Top));
}

如何使用 FormattedText 绘制非模糊文本？即我希望使用 TextOptions.TextFormattingMode="Display"和 TextOptions.TextRenderingMode="Aliased"。

FormattedText 有一个重载的构造函数，允许指定 TextFormattingMode:http://msdn.microsoft.com/en-us/library/ee474866.aspx

void DrawText(DrawingContext dc)
{
  FormattedText ft = new FormattedText("Hello World",
    System.Globalization.CultureInfo.CurrentCulture,
    System.Windows.FlowDirection.LeftToRight,
    new Typeface(FontFamily, FontStyle, FontWeight, FontStretch),
    FontSize,
    brush,
    null,
    TextFormattingMode.Display);
  dc.DrawText(ft, new Point(rect.Left, rect.Top));
}
