TikZ：菱形中的对角文字

Question

我需要制作一个带有水平文本的菱形，或者相应地在正方形中制作一个对角线文本，就像所示的两幅图像一样。

使用 TikZ 可以简单地实现这一点吗？

编辑：似乎第二个带有 itemize 的图无法使用 shapeparnode 完成，而第一个图的最佳方法是 shapeparnode。对于第二个图，我最终使用了节点内的 minipage。

如果有人有办法很好地列出文本的各个部分并使其居中，我仍然会非常感兴趣！

第二幅图的代码：

\documentclass[11pt]{standalone}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{tikz}
\usepackage{rotating}

\begin{document}

\begin{tikzpicture}
    \draw (0,0) rectangle (7.778174593,7.778174593)
        node[rotate=45,pos=.5, text width=7cm] {
            \begin{minipage}{\linewidth}
            \begin{center}
            Praktisk information:
            \end{center}
            \\
            \begin{itemize}
                \item Husk kød til fredag aften
                \item Husk sengelinned, dyne og pude eller sovepose
                \item Mountainbikecampens adresse er Slettestrandvej 26, 9690 Fjerritslev
                \item Ønskeseddel kan findes på ???
            \end{itemize}
            \end{minipage}
    };
\end{tikzpicture}

\end{document}

Answer 1

根据 Bobyandbob 的要求，我在下面发布了我的解决方案。如上面的评论所述，它基于这个答案，但解决方案仍然需要对空格进行一些手动调整。
