为什么此文档会增加空白页？

我有这个文档，它在开头添加了一个空白页，在结尾添加了两个空白页 - 这是为什么？我该如何删除它们？

因此，我最终得到了 5 页，而不是 2 页！

\documentclass{article}
\usepackage[paperheight=20.0mm, paperwidth=50.0mm, layoutheight=20.0mm, layoutwidth=50.0mm, layoutvoffset=0mm,  layouthoffset=0mm, margin=0pt, includeheadfoot, showframe=false, showcrop=false]{geometry}

\usepackage{forloop}
\usepackage{fmtcount}
\usepackage[first=1, last=2147483647, seed=28112018, counter=serialnumber]{lcg}
\newcounter{numpages}
\usepackage{tikz}
\newcommand{\mypic}[2]{
    \rand
    \begin{tikzpicture}[remember picture, overlay]
        \node (thispage) [shape=rectangle, fill=lightgray, minimum height=\paperheight, minimum width=\paperwidth, anchor=south west] at (current page.south west) {};
        \node[anchor=south] at (thispage.center) {\tiny bg picture here};  %\includegraphics[width=\paperwidth, height=\paperheight]{dummy.png}};
        \node at (thispage.center) {\decimal{#2} -- \padzeroes[10]{\decimal{#1}}};
    \end{tikzpicture}
    \newpage
}

\begin{document}
%\clearpage\thispagestyle{empty} % won't do much
\forloop{numpages}{1}{\value{numpages} < 3}{\mypic{serialnumber}{numpages}}

%\forloop{numpages}{1}{\value{numpages} < 11}{\mypic{serialnumber}{numpages}}
\end{document}

多余的页面是由于页眉和页脚无法打印。别忘了运行两次。

\documentclass{article}
\usepackage[paperheight=20.0mm, paperwidth=50.0mm, layoutheight=20.0mm, layoutwidth=50.0mm, layoutvoffset=0mm,  layouthoffset=0mm, margin=0pt, noheadfoot, showframe=false, showcrop=false]{geometry}

\usepackage{forloop}
\usepackage{fmtcount}
\usepackage[first=1, last=2147483647, seed=28112018, counter=serialnumber]{lcg}
\newcounter{numpages}
\usepackage{tikz}
\newcommand{\mypic}[2]{
    \rand
    \begin{tikzpicture}[remember picture, overlay]
        \node (thispage) [shape=rectangle, fill=lightgray, minimum height=\paperheight, minimum width=\paperwidth, anchor=south west] at (current page.south west) {};
        \node[anchor=south] at (thispage.center) {\tiny bg picture here};  %\includegraphics[width=\paperwidth, height=\paperheight]{dummy.png}};
        \node at (thispage.center) {\decimal{#2} -- \padzeroes[10]{\decimal{#1}}};
    \end{tikzpicture}
    \newpage
}

\begin{document}
%\clearpage\thispagestyle{empty} % won't do much
\forloop{numpages}{1}{\value{numpages} < 3}{\mypic{serialnumber}{numpages}}

%\forloop{numpages}{1}{\value{numpages} < 11}{\mypic{serialnumber}{numpages}}
\end{document}

使用时includeheadfoot，文本高度会减小以便为它们腾出空间，因此您的图片会变得太大而无法放入页面中，并且在使用图片之前页面顶部的断点。

使用选项也没有多大意义layout...，因为您指定了相同的页面宽度和高度。

还应小心宏中未受保护的空间。

您考虑过使用吗standalone？

\documentclass{article}
\usepackage[
  paperheight=20.0mm,
  paperwidth=50.0mm,
  margin=0pt,
]{geometry}

\usepackage{forloop}
\usepackage{fmtcount}
\usepackage[first=1, last=2147483647, seed=28112018, counter=serialnumber]{lcg}
\newcounter{numpages}
\usepackage{tikz}

\newcommand{\mypic}[2]{% <--- Here
  \rand
  \begin{tikzpicture}[remember picture, overlay]
    \node (thispage) [
      shape=rectangle,
      fill=lightgray,
      minimum height=\paperheight,
      minimum width=\paperwidth,
      anchor=south west
    ] at (current page.south west) {};
    \node[anchor=south] at (thispage.center) {\tiny bg picture here};
    %\includegraphics[width=\paperwidth, height=\paperheight]{dummy.png}};
    \node at (thispage.center) {\decimal{#2} -- \padzeroes[10]{\decimal{#1}}};
    \end{tikzpicture}% <--- Here
    \newpage
}

\pagestyle{empty}

\begin{document}

\forloop{numpages}{1}{\value{numpages} < 3}{\mypic{serialnumber}{numpages}}

\end{document}
