我认为理想情况下您要寻找的要么是两个TextBlocks
,要么OpacityMask
应用于顶部的一个;
<Grid MaxWidth="100">
<TextBlock Text="Hey check it out we can change object gradients! yay!" Foreground="Red"
TextWrapping="Wrap" HorizontalAlignment="Center" VerticalAlignment="Center"/>
<TextBlock Text="Hey check it out we can change object gradients! yay!" Foreground="Blue"
TextWrapping="Wrap" HorizontalAlignment="Center" VerticalAlignment="Center">
<TextBlock.OpacityMask>
<LinearGradientBrush StartPoint="0.1,0.1" EndPoint="0.75,0.75">
<LinearGradientBrush.GradientStops>
<GradientStop Offset="0.322" Color="Black"/>
<GradientStop Offset="0.739" Color="Transparent"/>
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
</TextBlock.OpacityMask>
</TextBlock>
</Grid>
或者您可以直接将 a 应用于LinearGradientBrush
(Foreground
或Background
其他元素)本身,例如;
<Border Width="100" Height="50">
<Border.Background>
<LinearGradientBrush StartPoint="0.062,0.552" EndPoint="0.835,0.548">
<LinearGradientBrush.GradientStops>
<GradientStop Offset="0.5" Color="White"/>
<GradientStop Offset="0.5" Color="Black"/>
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
</Border.Background>
<TextBlock Text="Hello World!" HorizontalAlignment="Center" VerticalAlignment="Center">
<TextBlock.Foreground>
<LinearGradientBrush StartPoint="0.1,0.1" EndPoint="0.75,0.75">
<LinearGradientBrush.GradientStops>
<GradientStop Offset="0.5" Color="Black"/>
<GradientStop Offset="0.5" Color="White"/>
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
</TextBlock.Foreground>
</TextBlock>
</Border>
或开始 80 年代风格的幻想;
<Border Width="100" Height="50">
<Border.Background>
<LinearGradientBrush StartPoint="0.472,0.047" EndPoint="0.47,0.942">
<LinearGradientBrush.GradientStops>
<GradientStop Offset="0.541" Color="White"/>
<GradientStop Offset="0.548" Color="Black"/>
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
</Border.Background>
<TextBlock Text="Hello World!" HorizontalAlignment="Center" VerticalAlignment="Center">
<TextBlock.Foreground>
<LinearGradientBrush StartPoint="0.472,0.047" EndPoint="0.47,0.942">
<LinearGradientBrush.GradientStops>
<GradientStop Offset="0.631" Color="Black"/>
<GradientStop Offset="0.635" Color="White"/>
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
</TextBlock.Foreground>
</TextBlock>
</Border>
试一试,希望这会有所帮助。
