Question

我必须显示一些带有缩放功能的圆圈，但我需要strokethickness保持不变。我怎样才能做到这一点？感谢。

<Grid x:Name="SelectedPanel"
    HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
    RenderTransformOrigin="0.5,0.5" IsHitTestVisible="False">
    <Grid.RenderTransform>
        <ScaleTransform
            ScaleX="{Binding some binding}"
            ScaleY="{Binding some binding}"/>
    </Grid.RenderTransform>
    <Ellipse
        Stroke="#09C900"
        StrokeThickness="3"
        StrokeDashArray="5 2"
        StrokeDashOffset="6"
        RenderTransformOrigin="0.5,0.5"/>
</Grid>

好吧，如果将ScaleTransform应用于Ellipse，则StrokeThickness将随元素的其余部分一起增长。我建议你操纵椭圆的宽度和高度。像这样......

<Ellipse
    Stroke="#09C900"
    StrokeThickness="3"
    StrokeDashArray="5 2"
    StrokeDashOffset="6"
    Width="{some binding}"
    Height="{some binding}"/>
