Wpf 内椭圆不在中心位置

我需要用动画定制RadioButton，我修改了一个动画的内椭圆。但是内椭圆没有加载到中心位置，对此有什么解决方案吗

我已经使用了这个样式，下面给出了示例代码。我刚刚对内部椭圆使用了DoubleAnimation

        <Style x:Key="RadioButtonStyle" TargetType="RadioButton">
        <Setter Property="Background" Value="White"/>
        <Setter Property="BorderBrush" Value="LightGray"/>
        <Setter Property="Foreground" Value="#333333"/>
        <Setter Property="FontSize" Value="12"/>
        <Setter Property="FontFamily" Value="Segoe UI"/>
        <Setter Property="Padding" Value="10 0"/>
        <Setter Property="BorderThickness" Value="1"/>

提前感谢。

您的父级网格容器是13，您的椭圆大小是8

由于13/8=1.625，因此当它通过measure（）/arrange（）将其设置为水平中心时，间距不能等于内椭圆的中心，因此预计会出现偏移

因此，您的答案只是简单的数学问题，如果您希望它正确居中，请将您的

网格

父容器大小更改为可分割的大小，如

Height=“12”Width=“12”

，然后它将根据您的需要居中

希望这有帮助，干杯

谢谢chris，您的解决方案不起作用了，在更改网格为14，椭圆为8后，效果很好。但我还是不明白确切的原因。

谢谢克里斯，在网格改为14，椭圆改为8后，它的工作状态很好。
