使用TextOptions.TextFormattingMode與FormattedText

Question

隨着WPF4您可以通過添加TextOptions.TextFormattingMode =「顯示」和TextOptions.TextRenderingMode =「別名」到你的XAML具有不模糊的文字：

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

這工作正常我除了當我用DrawingContext.DrawText繪製文本像這樣：

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繪製非模糊文本？即我想TextOptions.TextFormattingMode =「顯示」和TextOptions.TextRenderingMode =「別名」使用。

Answer 1

按照例如這裏Advanced Text Formatting和創建的TextFormatter對象，並使用TextLine.Draw（）

Answer 2

有用於FormattedText一個重載的構造函數，允許指定一個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)); 
}
