我修改了MWE使 TikZ 節點可超連結當我將樣本節點旋轉 60 度時得到以下結果：
我的願望是超連結與框一起旋轉。如..所示這裡，可以\rotatebox{...}在節點內使用，但這不會給出很好的結果：它旋轉節點內的文本，而不是邊界（或連結）。
修改後的 MWE 顯示了這兩種不太完美的結果，如下所示。
\documentclass{article}
\usepackage{hyperref}
\usepackage{tikz}
\usepackage{graphicx}
\usetikzlibrary{calc}
\begin{document}
\tikzset{
hyperlink node/.style={
alias=sourcenode,
append after command={
let \p1 = (sourcenode.north west),
\p2=(sourcenode.south east),
\n1={\x2-\x1},
\n2={\y1-\y2} in
node [inner sep=0pt, outer sep=0pt,anchor=north west,at=(\p1)] {\hyperlink{#1}{\XeTeXLinkBox{\phantom{\rule{\n1}{\n2}}}}}
%xelatex needs \XeTeXLinkBox, won't create a link unless it
%finds text --- rules don't work without \XeTeXLinkBox.
%Still builds correctly with pdflatex and lualatex
}
}
}

答案1
傾斜/傾斜/旋轉/傾斜的超連結是可能的！
PDF 規格定義了註釋字典/QuadPoints中的條目/Link，該條目定義了任意數量的四邊形的角座標，這些四邊形只需完全內接在通常的水平連結矩形內，並進一步確定超連結的滑鼠敏感區域。
原則，任意形狀文檔頁面中的區域可以變成超連結使用這種方法，只需將多個四邊形疊加即可。各個四邊形不需要是長方形，也不需要水平對齊。
唉，像往常一樣，這類高級 PDF 功能需要 Acrobat Reader。

考慮到 percusse 提到的限制（並感謝 Jasper Habicht 的評論，該評論是在我完成測試時發布的），這裡是一個計算旋轉角度的「改進」版本。
\documentclass{article}
\usepackage{hyperref}
\usepackage{tikz}
\usepackage{graphicx}
\usetikzlibrary{calc}
\begin{document}
\tikzset{
hyperlink node/.style={
alias=sourcenode,
append after command={
let \p1 = (sourcenode.north west),
\p2=(sourcenode.south east),
\p3 = (sourcenode.south west),
\n1={\x2-\x1},
\n2={\y1-\y2},
\n3={atan2(\y2-\y3,\x2-\x3)},
\n4={veclen(\y2-\y3,\x2-\x3)},
\n5={veclen(\y1-\y3,\x1-\x3)}
in
node [inner sep=0pt, outer sep=0pt,anchor=south
west,at=(\p3),rotate=\n3]
{\hyperlink{#1}{\XeTeXLinkBox{\phantom{\rule{\n4}{\n5}}}}}
%xelatex needs \XeTeXLinkBox, won't create a link unless it
%finds text --- rules don't work without \XeTeXLinkBox.
%Still builds correctly with pdflatex and lualatex
}
}
}
\tikz \node [draw, inner sep=2ex,hyperlink node=pagetwo,rotate=0] {Go to Page Two};
\bigskip
\tikz \node [draw, inner sep=2ex,hyperlink node=pagetwo,rotate=60] {Go to Page Two};
\bigskip
\tikz \node [draw, inner sep=2ex,hyperlink node=pagetwo,rotate=40] {Go to Page Two};
\bigskip
\tikz \node [draw, inner sep=2ex,hyperlink node=pagetwo] {\rotatebox{30}{\hyperref[pagetwo]{I said, Page Two}}};
\clearpage
\hypertarget{pagetwo}{Page Two}
\end{document}
xelatex 和其他編譯器的輸出不同。該版本針對 xelatex 進行了「最佳化」。
