使用 fancyhdr 将中心页脚与左、右页脚对齐

Question

我在特定文档中进行了以下设置：

\usepackage{fancyhdr}

% -- Header and footer --------------------------------------
\pagestyle{fancy}
\fancyhf{}
\setlength{\footskip}{32pt}
\rfoot{\includegraphics[height=12mm]{figures/Gradient1}}
\lfoot{\includegraphics[height=12mm]{figures/Gradient2}}
\cfoot{
   \tiny{Some really long piece of text that needs to \\ 
         be positioned at the centre of the footer}
   \\
   \normalsize{\thepage}}

产生以下页脚：

左、右页脚未与中心页脚垂直对齐。图像几乎与文本对齐，跳过了正文和页脚之间的空间。相反，我期望的是这样的：

有办法吗？

Answer 1

使用\parbox底部对齐方式来对齐中心脚。由于图像的底部位于基线上，因此您可以自动获得所需的效果。

\documentclass{article}
\usepackage{graphicx}
\usepackage{fancyhdr}

\usepackage{lipsum}

% -- Header and footer --------------------------------------

\setlength{\footskip}{48pt} % fancyhdr suggests at least 37.74333pt
\pagestyle{fancy}
\fancyhf{}
\fancyfoot[L]{\includegraphics[height=12mm]{example-image-1x1}}
\fancyfoot[R]{\includegraphics[height=12mm]{example-image-1x1}}
\fancyfoot[C]{%
  \parbox[b]{\textwidth}{%
    \centering
    {\tiny Some really long piece of text that needs to \\ 
           be positioned at the centre of the footer\\}
    \thepage
  }%
}

\begin{document}

\lipsum[1-10]

\end{document}

Answer 2

\documentclass{article}

\usepackage{fancyhdr,lipsum}
\usepackage[export]{adjustbox}
\usepackage{makecell}
\pagestyle{fancy}

\fancyhf{} % Clear header/footer
\fancyfoot[L]{\includegraphics[scale=0.22,valign=c]{example-image}}
\fancyfoot[C]{\begin{tabular}
        {@{}c@{}}
        \tiny {\makecell[c]{Some really long piece of text that\\ needs to  
        be positioned at the centre of the footer}}\\ \normalsize{\thepage}
    \end{tabular}}
\fancyfoot[R]{\includegraphics[scale=0.22,valign=c]{example-image}}

%\setlength{\footskip}{60pt}% Depends on image size

\begin{document}
    
    \lipsum[1-5]
    
\end{document}

Answer 3

我设法通过在数字前插入垂直空格来获得所需的效果。 问题是这是一个负空间：

\rfoot{\vspace{-3mm}\includegraphics[height=12mm]{figures/Gradient1}}
\lfoot{\vspace{-3mm}\includegraphics[height=12mm]{figures/Gradient2}}
