在 Beamer 中自定义标题页

在 Beamer 中自定义标题页

我把下面的 tikzpicture 借用自https://tex.stackexchange.com/a/86310/10898，在我的 Beamer 标题页中。

尽管如此，我还是想尝试两件事。一方面，将 tikzfigure 相对于页面水平放置，如果可能的话，在第二种情况下，减少标题颜色框的宽度。

有什么提示可以继续吗？非常感谢您的帮助！

更新：

对于第一个问题，我尝试使用旋转包，但没有成功。而对于第二个问题，我使用了此代码 \setbeamertemplate{title page}[default][rounded=true,shadow=true,wd=0.8\textwidth]，现在颜色框变短了，但它没有居中。

这是一种可能性；根据您的需要调整设置：

在此处输入图片描述

beamercolorbox标题所用的 的宽度现在由 的宽度控制\parbox，最初设置为0.75\paperwidth；您可以在标有 的行中更改此值% change the width here。
