来自单个 \includegraphics 的多个超链接

tag-icon • tag-icon graphics hyperref links
来自单个 \includegraphics 的多个超链接

我有一个像这样的图像，我已将其包含在\includegraphics命令中。

在此处输入图片描述

我希望每个圆圈都链接到文档的不同部分。例如，单击蓝色圆圈应将用户带到\label{blue}，单击绿色圆圈应将用户带到\label{green}，等等。

链接也可能是 URL，而不是文档内位置的链接。我得到的是类似于 HTML 中的地图/区域的内容（http://www.w3schools.com/tags/tag_area.asp）

为什么？因为所讨论的图像是由软件生成的，因此“地图”也可以由软件生成。子图不是一种选择，因为图形不能分开。

答案1

tikz这是一个节点覆盖图像并放置\hyperlinks在\nameref{...}各个部分的版本：

节点位置由用户决定！

在此处输入图片描述

\documentclass[oneside]{article}


\usepackage{blindtext}
\usepackage{tikz}
\usepackage{graphicx}


\newcommand{\namereflink}[1]{%
  \nameref{#1}%
% Or use
%  \hyperlink{section.\getrefnumber{#1}}{\nameref*{#1}}%
% Or use
%  \hyperlink{section.\getrefnumber{#1}}{\phantom{}}%  Difficult to detect!!!!
}

\usepackage{hyperref}

\begin{document}

\begin{center}
\begin{tikzpicture}[scale=4]
  \hypersetup{hidelinks}
  \node[inner sep=1pt] (MYCENTER) at (0,0) {\includegraphics[scale=1]{ente.jpg}};
  \node (BLUEEDGE) at (-1,1)    {\nameref{sec:blue}}; % For example
  \node (GREENEDGE) at (1,1)    {};
  \node  (REDEDGE) at (-1,-1)   {};
  \node  (ORANGEEDGE) at (1,-1) {};

  \shade[ball color=blue] (BLUEEDGE) circle (0.5);
  \shade[ball color=green] (GREENEDGE) circle (0.5);
  \shade[ball color=red] (REDEDGE) circle (0.5);
  \shade[ball color=orange] (ORANGEEDGE) circle (0.5);
\end{tikzpicture}
\end{center}

\clearpage

\section{Blue} \label{sec:blue}

\section{Red} \label{sec:red}

\blindtext[5]

\section{Green} \label{sec:green}

\blindtext[5]

\section{Orange} \label{sec:orange}
