我有这样的文本块
<TextBlock Text="BETA"
FontSize="28"
HorizontalAlignment="Right"
VerticalAlignment="Center"
Margin="0,17,420,271"
FontFamily="Georgia">
<TextBlock.RenderTransform>
<RotateTransform Angle="20" />
</TextBlock.RenderTransform>
<TextBlock.Foreground>
<LinearGradientBrush StartPoint="0,0"
EndPoint="0,24"
MappingMode="Absolute">
<GradientStopCollection>
<GradientStop Color="White"
Offset="0" />
<GradientStop Color="Orange"
Offset=".2" />
<GradientStop Color="DarkOrange"
Offset=".85" />
<GradientStop Color="White"
Offset="1" />
</GradientStopCollection>
</LinearGradientBrush>
</TextBlock.Foreground>
</TextBlock>
它不会呈现任何文本。如果我删除变换或画笔,那么它工作正常,但两者一起不会渲染任何东西。
