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