Silverlight-字体作为图标渲染太失真/像素化

Question

我目前将FontAwesome集成到了我的silverlight应用程序中。但是我注意到，在运行时实际上是像素化

<!-- RadButton (via custom Button) -->
<Style TargetType="controls:Button" x:Key="DefaultRadButtonStyle">
    <Setter Property="Background" Value="Transparent" />
    <Setter Property="Foreground" Value="{StaticResource DefaultColorBrush}" />
    <Setter Property="MouseOverStyle" Value="{StaticResource DefaultButtonMouseOverBorder}" />
    <Setter Property="FocusStyle" Value="{StaticResource DefaultButtonFocusBorder}" />
    <Setter Property="BorderBrush" Value="{StaticResource LineColorBrush}" />
    <Setter Property="BorderThickness" Value="0" />
    <Setter Property="FontFamily" Value="{StaticResource OpenSans-Regular}" />
    <Setter Property="Height" Value="{StaticResource CaptureGridRowHeightNumber}" />
    <Setter Property="Padding" Value="8, 0, 8, 1" />
    <Setter Property="FontSize" Value="13" />
    <Setter Property="Template">

用法：

<controls:Button
    Style="{StaticResource IconButtonStyle}"
    Command="{Binding RefreshCommand}">    
    <TextBlock Text="{StaticResource RefreshIcon}" Style="{StaticResource FontAwesomeTextBlockStyle}"/>
</controls:Button>

Answer 1

显然这是一个黑客

<Style x:Key="BaseFontAwesomeTextBlockStyle" TargetType="TextBlock">
    <Setter Property="FontSize" Value="16"/>
    <Setter Property="Foreground" Value="{StaticResource DefaultColorBrush}"/>
    <Setter Property="RenderTransform">
        <Setter.Value>
            <RotateTransform Angle="0.001"/>
        </Setter.Value>
    </Setter>
</Style>

我建议您使用Path而不是图像（如果您使用的是任何图像）。由于它是矢量路径，因此应基于父容器缩放，并且不会出现像素化问题（它比图像更快，并且使用的资源更少）。示例刷新图像，

<Path Stretch="Fill" Fill="#FF000000" Data="F1 M 38,20.5833C 42.9908,20.5833 47.4912,22.6825 50.6667,
