C# 如何在文本块上添加不模糊的dropshadow

问题说明了一切。我想不出来。我曾尝试添加一个镜像文本元素，但我有一个触发器，当鼠标位于该元素上时，它会更改字体大小，但由于主元素位于顶部，因此不会触发该触发器。如果要删除阴影的是文本本身，则通常的模糊解决方法不起作用

我正在考虑对此进行破解，并添加两个切换可见性的阴影文本块。但是，我不知道如何切换可见性，因为我不能使用

TargetName

或

DataTrigger

，因为它基于另一个元素，所以永远不会触发

每个请求（阴影被放大以便可以看到）：

我想出来了！我必须使用

标签

，这样我就可以使用

控制模板

，这样我就可以使用

数据触发器

和
