调整大小时使用思维导图放置超链接

Question

我有以下代码，用于根据 Beamer 演示文稿的章节/子章节构建思维导图。但是，当我缩放思维导图以适合框架区域时，超链接不仅是文本本身，而且是隐藏在 pdf 中的内容。如果将鼠标放在思维导图中的章节/子章节名称上并将鼠标向右移动，则可以看到它。文本名称结束，但超链接继续。我如何保证即使调整图片大小，超链接也会位于正确的位置。

Answer 1

选项的实现方式似乎存在问题scale。作为一种解决方法，将整个内容放在一个\scalebox作品中。（不过，您可能实际上希望为节点文本使用更大的字体大小；但此处的输出与使用scale=0.5选项时相同）。

我用 Skim.app（在 mac os x 上）的弹出窗口截取了一张屏幕截图，其左上角是指针所在的位置。但无法将指针合并到屏幕截图中。
