如何在打印 Latex Beamer Notes 时仅处理覆盖层

使用叠加层并在同一张幻灯片中显示多个图形甚至文本确实很棒，但我真的很想知道如何在打印幻灯片或笔记时显示每个叠加层？似乎有些幻灯片可以有多页才能准确显示所有图形和文本，尤其是当我们使用诸如\only<1-3和之类的叠加层时\only<4-5>。如果它只是普通文本并且只填充一页，那么应该没问题。但很多时候情况比这更复杂。有人能澄清一下我们在这种情况下能做什么吗？

编辑：添加了最少的示例

我的意思是，在第二张幻灯片上，我有三张不同的 tikz 图片。这里我没有包含节点 (0,0) 上的图片。在我的幻灯片中，我使用了图片。那么，我怎样才能在同一页上打印这三张图片？在其他情况下，一些文本也不适合幻灯片。我希望现在更容易理解了。

将我的上述评论转化为答案：

在指定叠加选项时，您可以添加选项handout:<number>。例如，\only<1-3| handout:1>{content-1}将打印content-1出现在第 1 至第 3 帧中的作为讲义第一页的内容；\only<4-5| handout:2>{content-2}将打印content-2出现在第 4 和第 5 帧中的作为讲义第二页的内容；并将\only<6-| handout:0>{content-3}指示 beamer 不要打印出现在第 6 帧及以后的内容。请注意，和content-3之间需要一个空格。|handout

若要不在讲义中显示某个项目/图形，只需设置handout:0。
