href 无法与图像配合使用（但可以与文本配合使用）

Question

自 2012/08/18 版本起，v6.83b 软件包hyperref提供了\XeTeXLinkBox此用途，其内容如下README：

\XeTeXLinkBox
-------------
  When XeTeX generates a link annotation, it does not look
  at the boxes (as the other drivers), but only at the character
  glyphs. If there are no glyphs (images, rules, ...), then
  it does not generate a link annotation. Macro \XeTeXLinkBox
  puts its argument in a box and adds spaces at the lower left
  and upper right corners. An additional margin can be specified
  by setting it to the dimen register \XeTeXLinkMargin. The default
  is 2pt.

  Example:
    % xelatex
    \documentclass{article}
    \usepackage{hyperref}
    \setlength{\XeTeXLinkMargin}{1pt}
    \begin{document}
    \section{Hello World}
    \newpage
    \label{sec:hello}
    \hyperref[sec:hello]{%
      \XeTeXLinkBox{\rule{10mm}{10mm}}%
    }
    \end{document}

下面的示例重新定义自动\includgraphics添加\XeTeXLinkBox。

\documentclass{article}
\usepackage{hyperref}[2012/08/18]
\usepackage{graphicx}

\ifxetex
  \usepackage{letltxmacro}
  \setlength{\XeTeXLinkMargin}{1pt}
  \LetLtxMacro\SavedIncludeGraphics\includegraphics
  \def\includegraphics#1#{% #1 catches optional stuff (star/opt. arg.)
    \IncludeGraphicsAux{#1}%
  }%
  \newcommand*{\IncludeGraphicsAux}[2]{%
    \XeTeXLinkBox{%
      \SavedIncludeGraphics#1{#2}%
    }%
  }%
\fi

\begin{document}
  \href{http://www.example.com/}{\XeTeXLinkBox{\rule{10mm}{10mm}}}

  \href{http://www.example.com/}{\includegraphics[scale=3]{care}}

  \href{http://www.example.com/}{Text works fine!}
\end{document}
