我需要一个进度条，它会在一些固定的时间间隔后显示点和图标。我正在研究相机模块，当拍摄快照时，我需要在进度条中显示点，这表明已拍摄快照。然后这个快照被传递给算法并返回布尔值，然后我需要显示图标。

如果持续时间为 1 分钟且间隔为 30 秒，那么在进度条控件中，我需要在进度条中显示两个点和两个图标。

请给我一些解决方案，下面是 XAMl

XAML 用于进度条

<Window.Resources>

    <Style x:Key="ProgressBarStyle" TargetType="ProgressBar">

        <Setter Property="Template">
            <Setter.Value>
