\usepackage{tikz}

我想要的是

我想实现两个用 绘制的按钮tikzpicture，一个用于上一页，另一个用于下一页（单击它们）：

我想要的是

我做了什么

我无法在页码周围添加这些图画。图画是一个箭头：

\begin{tikzpicture}[remember picture,overlay]
    \draw[line width=1mm,red] (.3,.3) -- (0,0) -- (.3,-.3);
\end{tikzpicture}

指向左侧的箭头

我尝试使用没有效果的坐标，并尝试使用 + 移位的位置current page.south west，但是我不能：

\documentclass{article}
\usepackage[a4paper,margin=1in,footskip=0.25in]{geometry}

\usepackage{tikz}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\rfoot{
    \begin{tikzpicture}[remember picture,overlay]
        \fill[black] (current page.south west) rectangle ++(\paperwidth,1.5cm) node[midway,align=center,font=\LARGE,text=white] {\bfseries\thepage}; % From https://tex.stackexchange.com/a/443744/152550
        \draw[line width=1mm,white] (current page.south west) -- ++(.5cm,.5cm) -- (.3,-.3); % This should be placed near the page number, and there should be another arrow pointing to the right
    \end{tikzpicture}
}

我们如何将这些箭头放在页码附近？

答案1

怎么样

\documentclass{article}
\usepackage[a4paper,margin=1in,footskip=0.25in]{geometry}

\usepackage{tikz}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\rfoot{
    \begin{tikzpicture}[remember picture,overlay]
        \fill[black] (current page.south west) rectangle ++(\paperwidth,1.5cm)
        node[midway,align=center,font=\LARGE\bfseries,text=white] 
        (pageno-\number\value{page}) {\thepage}; % From https://tex.stackexchange.com/a/443744/152550
        \draw[white,ultra thick,line cap=round,line join=round] 
         ([xshift=-\paperwidth/4]pageno-\number\value{page}.south)
         --  ([xshift=-\paperwidth/4-7pt]pageno-\number\value{page}.center)
         -- ([xshift=-\paperwidth/4]pageno-\number\value{page}.north)
         ([xshift=\paperwidth/4]pageno-\number\value{page}.south)
         --  ([xshift=\paperwidth/4+7pt]pageno-\number\value{page}.center)
         -- ([xshift=\paperwidth/4]pageno-\number\value{page}.north);
    \end{tikzpicture}
}

这是更通用的版本。箭头仅在有意义时出现，单击它们即可移动到上一页或下一页。

\documentclass{article}
\usepackage[a4paper,margin=1in,footskip=0.25in]{geometry}

\usepackage{tikz}
\usepackage{hyperref}
\usepackage{lastpage}
\usepackage{refcount}
\usepackage{fancyhdr}
\pagestyle{fancy}
\newsavebox{\manoooharrowL}
\newsavebox{\manoooharrowR}
\sbox\manoooharrowR{\begin{tikzpicture}
\draw[line width=1mm,white,line cap=round,line join=round] 
(0,0) -- (7pt,8pt) -- (0pt,16pt);
\end{tikzpicture}}
\sbox\manoooharrowL{\begin{tikzpicture}
\draw[line width=1mm,white,line cap=round,line join=round] 
(0,0) -- (-7pt,8pt) -- (0pt,16pt);
\end{tikzpicture}}
\fancyhf{}
\rfoot{
    \begin{tikzpicture}[remember picture,overlay]
        \fill[black] (current page.south west) rectangle ++(\paperwidth,1.5cm)
        node[midway,align=center,font=\LARGE\bfseries,text=white,xscale=1.5] 
        (pageno-\number\value{page}) 
        {\thepage}; % From https://tex.stackexchange.com/a/443744/152550
        \ifnum\value{page}<\getpagerefnumber{LastPage}
         \path ([xshift=\paperwidth/4]pageno-\number\value{page}) 
            node{\hyperlink{page.\the\numexpr\value{page}+1}{\usebox\manoooharrowR}};
        \fi
        \ifnum\value{page}>1
         \path ([xshift=-\paperwidth/4]pageno-\number\value{page}) 
            node{\hyperlink{page.\the\numexpr\value{page}-1}{\usebox\manoooharrowL}};

这是一个非常简单的方法：

输出

\documentclass{article}
\usepackage[a4paper,margin=1in,footskip=0.25in]{geometry}

\usepackage{tikz}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\rfoot{
    \begin{tikzpicture}[remember picture,overlay]
        % From https://tex.stackexchange.com/a/443744/152550
        \fill[black] (current page.south west) rectangle ++(\paperwidth,1.5cm) 
        node[midway,align=center,font=\LARGE,text=white] (pgNum){\bfseries\thepage};
        % Left arrow
        \node[left of=pgNum, xshift=-3cm, scale=4, 
            path picture={\draw[line width=1mm, red] (.3,.3) -- (0,0) -- (.3,-.3);}] {};
        % Right arrow
        \node[right of=pgNum, xshift=3cm, scale=4, 
            path picture={\draw[line width=1mm, red] (-.3,-.3) -- (0,0) -- (-.3,.3);}] {};
