使用 scrlayer 方法时页码会消失

我正在使用下面的代码，它是作为另一个问题的答案提供的这里。

问题是：在用 声明页面样式的那一刻\DeclarePageStyleByLayers{firstpage}{topbox}，页码就消失了。如果 的行\DeclarePageStyleByLayers...被标记（=取出=没有框架），则页码会出现。

我其实奥尔尼使用提供给我的这段代码，我只理解了表面。我原本以为 Tex 会放置页码，然后覆盖框架，但显然事实并非如此。

我想在框架内显示页码。如何实现？

\documentclass{article}
\usepackage{scrlayer}
\usepackage{multicol}
\usepackage[savepos]{zref}
\usepackage{lipsum}

\newlength{\marginpadding}
\setlength{\marginpadding}{4pt}

\DeclareNewLayer[textarea,background,mode=picture,
  addheight=2\marginpadding,
  addwidth=2\marginpadding,
  addhoffset=-\marginpadding,
  addvoffset=-\marginpadding,
  contents={%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUR{\line(-1,0){\LenToUnit{\layerwidth}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{topbox}
\DeclareNewLayer[clone=topbox,
  contents={%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{midbox}
\DeclareNewLayer[clone=topbox,
  height={\pdfpageheight-\zposy{textbottom}sp-\layeryoffset-\baselineskip+\marginpadding},
  contents={%
  \putLL{\line(1,0){\LenToUnit{\layerwidth}}}%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{bottombox}
\DeclarePageStyleByLayers{firstpage}{topbox}   % delete the whole line to see the pagenumber to appear
\DeclarePageStyleByLayers{midpage}{midbox}     % delete the whole line to see the pagenumber to appear
\DeclarePageStyleByLayers{lastpage}{bottombox} % delete the whole line to see the pagenumber to appear
\pagestyle{midpage}
\begin{document}
\thispagestyle{firstpage}
\begin{multicols}{2}
  \lipsum[1-10]       
\end{multicols}

\lipsum[1-2]

\begin{multicols}{2}
  \lipsum[1-10]
\end{multicols}
\zsaveposy{textbottom}
\thispagestyle{lastpage}
\end{document}

答案1

页码消失是因为页面样式已被替换。要恢复页码，只需添加另一个包含页码的图层，以及页脚中所需的任何其他内容，并添加适当的额外距离以扩展框架。

此版本将页码置于中央，并且不进行任何格式化。如果您想要更酷炫的功能（例如奇偶页更改），则需要对其进行修改。

\documentclass{article}
\usepackage{scrlayer}
\usepackage{multicol}
\usepackage[savepos]{zref}
\usepackage{lipsum}

\newlength{\marginpadding}
\setlength{\marginpadding}{4pt}

\DeclareNewLayer[foot,contents={\parbox{\layerwidth}{\centering\thepage}}]{pagenum}
\DeclareNewLayer[textarea,background,mode=picture,
  addheight=2\marginpadding+\footskip,
  addwidth=2\marginpadding,
  addhoffset=-\marginpadding,
  addvoffset=-\marginpadding,
  contents={%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUR{\line(-1,0){\LenToUnit{\layerwidth}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{topbox}
\DeclareNewLayer[clone=topbox,
  contents={%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{midbox}
\DeclareNewLayer[clone=topbox,
  height={\pdfpageheight-\zposy{textbottom}sp-\layeryoffset-\baselineskip+ \marginpadding},
  contents={%
  \putLL{\line(1,0){\LenToUnit{\layerwidth}}}%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{bottombox}
\DeclarePageStyleByLayers{firstpage}{topbox,pagenum}
\DeclarePageStyleByLayers{midpage}{midbox,pagenum}
\DeclarePageStyleByLayers{lastpage}{bottombox,pagenum}
\pagestyle{midpage}
\begin{document}
\thispagestyle{firstpage}
\begin{multicols}{2}
  \lipsum[1-10]       
\end{multicols}

\lipsum[1-2]

\begin{multicols}{2}
  \lipsum[1-10]
\end{multicols}
\zsaveposy{textbottom}
\thispagestyle{lastpage}
\end{document}

您可以加载包scrlayer-scrpage并将所有页面样式层添加scrheadings到新的页面样式中。然后您可以使用\cfoot或\ofoot等来设置页码。

\documentclass{article}
\usepackage[manualmark]{scrlayer-scrpage}
\usepackage{multicol}
\usepackage[savepos]{zref}
\usepackage{lipsum}

\newlength{\marginpadding}
\setlength{\marginpadding}{4pt}

\DeclareNewLayer[textarea,background,mode=picture,
  addheight=2\marginpadding,
  addwidth=2\marginpadding,
  addhoffset=-\marginpadding,
  addvoffset=-\marginpadding,
  contents={%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUR{\line(-1,0){\LenToUnit{\layerwidth}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{topbox}
\DeclareNewLayer[clone=topbox,
  contents={%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{midbox}
\DeclareNewLayer[clone=topbox,
  height={\pdfpageheight-\zposy{textbottom}sp-\layeryoffset-\baselineskip+\marginpadding},
  contents={%
  \putLL{\line(1,0){\LenToUnit{\layerwidth}}}%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{bottombox}
\DeclarePageStyleByLayers{firstpage}{topbox}
\DeclarePageStyleByLayers{midpage}{midbox}
\DeclarePageStyleByLayers{lastpage}{bottombox}

\ForEachLayerOfPageStyle*{scrheadings}{%
    \AddLayersToPageStyle{firstpage}{#1}%
    \AddLayersToPageStyle{midpage}{#1}%
    \AddLayersToPageStyle{lastpage}{#1}%
}
\clearpairofpagestyles
\cfoot*{\pagemark}


\pagestyle{midpage}
\begin{document}
\thispagestyle{firstpage}
\begin{multicols}{2}
  \lipsum[1-10]       
\end{multicols}

\lipsum[1-2]

\begin{multicols}{2}
  \lipsum[1-10]
\end{multicols}
\zsaveposy{textbottom}
\thispagestyle{lastpage}
\end{document}

或者你可以使用

\documentclass[twoside]{article}
\usepackage{scrlayer-scrpage}
\usepackage{multicol}
\usepackage[savepos]{zref}
\usepackage{lipsum}

\newlength{\marginpadding}
\setlength{\marginpadding}{4pt}

\DeclareNewLayer[textarea,background,mode=picture,
  addheight=2\marginpadding,
  addwidth=2\marginpadding,
  addhoffset=-\marginpadding,
  addvoffset=-\marginpadding,
  contents={%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUR{\line(-1,0){\LenToUnit{\layerwidth}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{topbox}
\DeclareNewLayer[clone=topbox,
  contents={%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{midbox}
\DeclareNewLayer[clone=topbox,
  height={\pdfpageheight-\zposy{textbottom}sp-\layeryoffset-\baselineskip+\marginpadding},
  contents={%
  \putLL{\line(1,0){\LenToUnit{\layerwidth}}}%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{bottombox}

\newpairofpagestyles{firstpage}{\cfoot{\pagemark}}
\newpairofpagestyles{midpage}{\cfoot{\pagemark}}
\newpairofpagestyles{lastpage}{\cfoot{\pagemark}}

\AddLayersToPageStyle{firstpage}{topbox}
\AddLayersToPageStyle{midpage}{midbox}
\AddLayersToPageStyle{lastpage}{bottombox}


\pagestyle{midpage}
\begin{document}
\thispagestyle{firstpage}
\begin{multicols}{2}
  \lipsum[1-10]       
\end{multicols}

\lipsum[1-2]

\begin{multicols}{2}
  \lipsum[1-10]
\end{multicols}
\zsaveposy{textbottom}
\thispagestyle{lastpage}
\end{document}

如果页码应该在框中，则添加\footskip并可能添加\dp\strutbox到所有框的高度并删除图层的更改高度bottombox：

\documentclass[twoside]{article}
\usepackage{scrlayer-scrpage}
\usepackage{multicol}
%\usepackage[savepos]{zref}
\usepackage{lipsum}

\newlength{\marginpadding}
\setlength{\marginpadding}{4pt}

\DeclareNewLayer[textarea,background,mode=picture,
  addheight=2\marginpadding+\footskip+\dp\strutbox,% changed
  addwidth=2\marginpadding,
  addhoffset=-\marginpadding,
  addvoffset=-\marginpadding,
  contents={%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUR{\line(-1,0){\LenToUnit{\layerwidth}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{topbox}
\DeclareNewLayer[clone=topbox,
  contents={%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{midbox}
\DeclareNewLayer[clone=topbox,
  %height={\pdfpageheight-\zposy{textbottom}sp-\layeryoffset-\baselineskip+\marginpadding},% removed
  contents={%
  \putLL{\line(1,0){\LenToUnit{\layerwidth}}}%
  \putLR{\line(0,1){\LenToUnit{\layerheight}}}%
  \putUL{\line(0,-1){\LenToUnit{\layerheight}}}%
}]{bottombox}

\newpairofpagestyles{firstpage}{\cfoot{\pagemark}}
\newpairofpagestyles{midpage}{\cfoot{\pagemark}}
\newpairofpagestyles{lastpage}{\cfoot{\pagemark}}

\AddLayersToPageStyle{firstpage}{topbox}
\AddLayersToPageStyle{midpage}{midbox}
\AddLayersToPageStyle{lastpage}{bottombox}


\pagestyle{midpage}
\begin{document}
\thispagestyle{firstpage}
\begin{multicols}{2}
  \lipsum[1-10]       
\end{multicols}

\lipsum[1-2]

\begin{multicols}{2}
  \lipsum[1-10]
\end{multicols}
\zsaveposy{textbottom}
\thispagestyle{lastpage}
\end{document}

我现在使用了 Karl 的版本并添加了一层页码 最后一页允许包含最后一个页码进入框架。另外，我摆弄了框架最后一页稍长一点以提供页码的空间。现在它看起来是这样的：

\documentclass[fontsize=9pt]{scrartcl}
