我正在尝试放入tikzpicture。beamer目前，我正在模式下在单独的 PDF 文件中创建它article，然后裁剪它；因为我不知道如何缩放tikzpicture以适合我的beamer窗口。
我在这里放置了一个完整的实数flowchart，我想直接在 beamer 中使用。任何帮助都会有用。

\tikzstyle{block} = [rectangle, draw, fill={rgb:red,3;green,39;blue,233},
text width=8em, text centered, rounded corners, minimum height=4em, node distance=2cm,

您可以使用\scalebox。结果并不美观，但最终的缩放和定位留给您。
