我修改了 MWE使 TikZ 节点可超链接当我将示例节点旋转 60 度时,得到以下结果:
我希望超链接能随着框一起旋转。如所示这里,可以\rotatebox{...}
在节点内使用,但这不会产生很好的结果:它旋转节点内的文本,但不旋转边界(或链接)。
修改后的 MWE 显示了这两种不太完美的结果。

答案1
斜向 / 倾斜 / 旋转 /倾斜的可以实现超链接!
PDF 规范定义了注释字典/QuadPoints
中的条目/Link
,该条目定义了任意数量的四边形的角坐标,这些四边形只需完全内接在通常的水平链接矩形内,并进一步确定超链接的鼠标敏感区域。
原则,任意形状文档页面中的区域可能会变成超链接使用这种方法,只需将多个四边形叠加即可。单个四边形不必是矩形,也不必水平对齐。
唉,像往常一样,这种高级 PDF 功能需要 Acrobat Reader。

考虑到 percusse 提到的局限性(并承认 Jasper Habicht 的评论,该评论是在我完成测试时发布的),这里有一个计算旋转角度的“改进”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
}
}

xelatex 和其他编译器的输出有所不同。此版本针对 xelatex 进行了“优化”。
