如何改变 Fancyref 的页码编号行为？

我正在使用 Fancyref (\Fref{}) 包进行交叉引用，但每个引用都采用“下一页图 4“。我怎样才能告诉包只包含”第 xxx 页“如果参考目标很远（例如超过5页）？

包fancyref使用包varioref. \reftextafter，\reftextbefore可以重新定义为隐藏其文本。\reftextfaraway如果引用的对象距离五页或更多页，也可以重新定义为仅打印文本：

\documentclass{article}
\usepackage{fancyref}

\renewcommand*{\reftextfaceafter}{\unskip}
\renewcommand*{\reftextafter}{\unskip}
\renewcommand*{\reftextfacebefore}{\unskip}
\renewcommand*{\reftextbefore}{\unskip}
\makeatletter
\let\saved@reftextfaraway\reftextfaraway
\renewcommand*{\reftextfaraway}[1]{%
  \begingroup
    \def\ref@unknown@value{??}%
    \ifx\@tempa\ref@unknown@value
      \count@=0 %
    \else
      \count@\thevpagerefnum\relax
      \advance\count@ by -\@tempa\relax
      \ifnum\count@<0 \count@=-\count@\fi
    \fi
    \ifnum\count@<5 %
      \unskip
    \else
      \saved@reftextfaraway{#1}%
    \fi
  \endgroup
}
\makeatother

\begin{document}
\begin{figure}
  \caption{Dummy figure}
  \label{fig:dummy}
\end{figure}
\clearpage
\Fref{fig:dummy} contains a dummy figure.
\clearpage
\Fref{fig:dummy} contains a dummy figure.
\clearpage
\Fref{fig:dummy} contains a dummy figure.
\clearpage
\Fref{fig:dummy} contains a dummy figure.
\clearpage
\Fref{fig:dummy} contains a dummy figure.
\end{document}

结果：

<Page 1> Figure 1: Dummy figure
<Page 2> Figure 1 contains a dummy figure.
<Page 3> Figure 1 contains a dummy figure.
<Page 4> Figure 1 contains a dummy figure.
<Page 5> Figure 1 contains a dummy figure.
<Page 6> Figure 1 on page 1 contains a dummy figure.
