保持投影仪中项目的位置

我希望在投影仪演示文稿中使用这样的幻灯片，但有两点小区别：

1) 物品必须位于同一点，并且不会消失在框架中。为此，我尝试使用覆盖区域但没有结果；

2) 带有翼型的图片中的箭头太大，我希望箭头小一点或者大一点。

关闭：有人可以告诉我如何在 tex.stackexchange 中编写代码来打印乳胶的精确结果？

答案1

将项目要点对齐到恒定高度的一种简单方法是使用 将列顶部对齐[onlytextwidth,T]。顶部减少的空间可以用\vspace{}足够长度的 来补偿。

采用这种方法，您可能不再需要它overlayarea，但由于您的代码结构不太好，所以我不想深入研究它。

在此处输入图片描述
