自定义进度栏模板剪切WPF

Question

我正在尝试为我的wpf项目创建自定义进度条控件。我无法以正确的方式剪辑动画和指示器部分。我尝试过使用Rectangle.Clip，但它没有用。

我也想知道是否有办法将“CornerRadius”属性绑定到“height / 2”。

<Style x:Key="VProgressBar" TargetType="{x:Type ProgressBar}">
        <Setter Property="Foreground" Value="#01D328"/>
        <Setter Property="Background" Value="{StaticResource ProgressBarBackground}"/>
        <Setter Property="BorderBrush" Value="{StaticResource ProgressBarBorderBrush}"/>
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ProgressBar}">
                    <Grid x:Name="TemplateRoot" SnapsToDevicePixels="true">

                        <Rectangle x:Name="PART_Track" Margin="1"/>
