Question

如何展示形象,因此,它应当始终能够看一看(因为图像色谱好坏参半,难以预测)?

我想到两个选择:

Making the text border in white while the text itself will be black
Having the text displayed negatively to the picture

The 1st option would be preferred since it looks more solid.

删除案文简单:

<Grid>
  <Image Source="{Binding ImageLink}" Width="110" />
  <TextBlock Text="{Binding Description}" 
    HorizontalAlignment="Center" 
    VerticalAlignment="Center" />
</Grid>

Update on answer:

就像一个伟大的想法一样,但并不奏效。

我研究了你的法典,这里是结果:

左面图像是:我设定了<代码>Color Property to White和ShadowDepth至10。

我这样做,帮助:

<Style x:Key="AnnotationStyle" TargetType="TextBlock">
  <Setter Property="Background" Value="#70FFFFFF" />
  <Setter Property="FontWeight" Value="Bold" />
  <Setter Property="HorizontalAlignment" Value="Center"/>
  <Setter Property="VerticalAlignment" Value="Center"/>
  <Setter Property="TextAlignment" Value="Center"/>
  <Setter Property="TextWrapping" Value="Wrap"/>
  <Style.Triggers>
    <Trigger Property="IsMouseOver" Value="True">
      <Setter Property="Background" Value="#CCFFFFFF" />
    </Trigger>
  </Style.Triggers>
</Style>

....

<TextBlock ... Style="{StaticResource AnnotationStyle}"/>

Here is what it looks like:

Answer 2

The best way to make the text more highlighted or contrasted is by using any effect, particularly the shader effects. Microsoft is also make bitmap effect obsoleted since .NET 3.5 SP1, therefore your best bet is using any shader effect or create your own.

例如(, 您可使用DopShadowEffect to “outline” You text,但将影印到0:

<Grid>
     <Image Source="{Binding ImageLink}" Width="110" />   
     <TextBlock Text="{Binding Description}" 
         HorizontalAlignment="Center" 
         VerticalAlignment="Center">
         <TextBlock.Effect>
             <DropShadowEffect ShadowDepth="0" Color="Blue" BlurRadius="10" />
         </TextBlock.Effect>
     </TextBlock> 
</Grid>

就更多的抽样而言,你可以探讨世界森林论坛的影响。

<><>UPDATE: 您也可通过使用TextOptions.TextRenderingMode所附财产,将其改为“Aliased”,或也可使用TextOptions.TextFormattingMode,并规定“Display”。

2. 进行这方面的比较,看看它是否适合你的需要:

<StackPanel>
    <TextBlock>
        Hello World ...  Ideal text formatting
    </TextBlock>
    <TextBlock TextOptions.TextFormattingMode="Display">
        Hello World ... Display text formatting
    </TextBlock>
</StackPanel>

希望这一帮助。
