我们都知道该类的标准转换beamer（例如\transblindhorizontal等等）。但我想知道是否可以进行自定义转换。以下是一个例子：考虑以下 MWE（非常粗略，但只是一个例子）。

我如何制作一个过渡来展示美元钞票如何“行走”在其路径上。我认为使用动画线是可行的，但我真的很希望通过选项\walkalong（例如\transboxout）使用此过渡。
答案1
转换并不嵌入在 pdf 本身中，仅仅是 pdf 查看器使用 pdf 标准中识别的转换之一的信息。
这意味着您无法向您的 Beamer 演示文稿添加自定义过渡，除非您还能说服 pdf 查看器等的创建者识别您的新过渡。
也就是说，你可以使用其他技术为你的美元钞票创建动画，例如如何将两个或多个平行图像移动到投影机中的固定位置相交
