Latex 图像页眉和页脚

Question

我正在尝试在 LaTex 中创建一个机构页面，该页面必须具有我的机构提供的页眉和页脚，并且无法更改，所以我试图用我的下一个代码强制它们借用这里https://tex.stackexchange.com/questions/297240/adding-an-image-to-a-header-in-latex

\documentclass[12pt,letterpaper]{article}


\usepackage{fancyhdr}

\pagestyle{fancy}
\usepackage{tikz}
\usetikzlibrary{calc}
\usepackage{tikzpagenodes}
\renewcommand{\headrulewidth}{0pt}
\renewcommand{\footrulewidth}{0pt}


\fancyfoot[R]{\begin{tikzpicture}[remember picture,overlay]
\draw  let \p1=($(current page footer area.north)-(current page.south)$),
      \n1={veclen(\x1,\y1)} in
node [inner sep=0,outer sep=0,below right] 
      at (current page.south west){\includegraphics[width=\paperwidth,height=\n1]{exampleH}};
\end{tikzpicture}}


\fancyhead[L]{\begin{tikzpicture}[remember picture,overlay]
\draw  let \p1=($(current page.north)-(current page header area.south)$),
      \n1={veclen(\x1,\y1)} in

问题是您将页脚图片放置在页面底部边框下方。如果您将节点放在下边界上方，您会看到它：

      \n1={veclen(\x1,\y1)} in

      at (current page.south west){\includegraphics[width=\paperwidth,height=\n1]{example-image-duck}};
