带有新部分的页面上标题 (KomaScript) 中颜色渐变的框

Question

不幸的是，我不太明白期望的结果是什么。但我建议为标题背景定义一个新层：

\DeclareNewLayer[
  background,
  head,
  hoffset=0pt,
  width=\paperwidth,
  mode=picture,
  contents={\putLL{\tikz{
    \ifodd \value{page}
      \fill[shade,left color=blue!0,right color=blue!70]
      (0,0)rectangle(\the\layerwidth,\the\layerheight);
    \else
      \fill[shade,left color=blue!70,right color=blue!0]
      (0,0)rectangle(\the\layerwidth,\the\layerheight);
    \fi
  }}
}
]{highlights.bg}

然后您可以在新定义的页面样式的开头添加此层：

\newpairofpagestyles{highlights}{
  \ohead{\pagemark}
  \KOMAoptions{headsepline=false}
  \addtokomafont{pagenumber}{\bfseries\color{white}}
}
\AddLayersAtBeginOfPageStyle{highlights}{highlights.bg}

例子：

\documentclass[12pt,ngerman, twoside]{scrartcl}

\usepackage[T1]{fontenc}
%\usepackage[utf8]{inputenc}% needed with older TeX distributions
\usepackage{lmodern} 
\usepackage{babel} 
\usepackage[left=3.8cm,right=2.2cm,top=3cm,bottom=3cm]{geometry}  
\usepackage{tikz}% loads xcolor, graphicx etc.

\usepackage[headsepline]{scrlayer-scrpage}
\clearpairofpagestyles
\renewcommand*\pagemark{{\usekomafont{pagenumber}Seite\nobreakspace\thepage}}
\automark[section]{section}
\ihead{\headmark}
\ohead*{\pagemark}

\newpairofpagestyles{highlights}{
  \ohead{\pagemark}
  \KOMAoptions{headsepline=false}
  \addtokomafont{pagenumber}{\bfseries\color{white}}
}
\DeclareNewLayer[
  background,
  head,
  hoffset=0pt,
  width=\paperwidth,
  mode=picture,
  contents={\putLL{\tikz{
    \ifodd \value{page}
      \fill[shade,left color=blue!0,right color=blue!70]
      (0,0)rectangle(\the\layerwidth,\the\layerheight);
    \else
      \fill[shade,left color=blue!70,right color=blue!0]
      (0,0)rectangle(\the\layerwidth,\the\layerheight);
    \fi
  }}
}
]{highlights.bg}
\AddLayersAtBeginOfPageStyle{highlights}{highlights.bg}

\usepackage{blindtext}% only for dummy text
\begin{document}
\section{Section 1}
Some text.

\cleardoublepage
\thispagestyle{highlights}
\blinddocument
\end{document}

但是，如果文档中的每个部分都应该从新的奇数页开始，那么您可以使用选项切换到类scrreprt。open=right因此，这里有一个额外的建议，假设 pagestylehighlights使用与 pagestyle 相同的图层plain.scrheadings和新图层highlight.bg：

\documentclass[12pt,ngerman, twoside,open=right]{scrreprt}
\RedeclareSectionCommand[beforeskip=0pt,afterindent=false]{chapter}

\usepackage[T1]{fontenc}
%\usepackage[utf8]{inputenc}% needed with older TeX distributions
\usepackage{lmodern} 
\usepackage{babel} 
\usepackage[left=3.8cm,right=2.2cm,top=3cm,bottom=3cm]{geometry}  
\usepackage{tikz}% loads xcolor, graphicx etc.

\usepackage[headsepline]{scrlayer-scrpage}
\clearpairofpagestyles
\renewcommand*\pagemark{{\usekomafont{pagenumber}Seite\nobreakspace\thepage}}
\automark[chapter]{chapter}
\ihead{\headmark}
\ohead*{\pagemark}

\DeclareNewLayer[
  background,
  oddpage,% not on even pages in two-sided documents
  head,
  hoffset=0pt,
  width=\paperwidth,
  mode=picture,
  contents={\putLL{\tikz{
    \fill[shade,left color=blue!0,right color=blue!70]
      (0,0)rectangle(\the\layerwidth,\the\layerheight);
  }}
}
]{highlights.bg}
\DeclareNewPageStyleByLayers{highlights}{highlights.bg}
\ForEachLayerOfPageStyle{plain.scrheadings}{\AddLayersToPageStyle{highlights}{#1}}% <- add all plain.scrheadings layers to the new page style
\AddToLayerPageStyleOptions{highlights}{oninit=\addtokomafont{pagenumber}{\bfseries\color{white}}\KOMAoptions{headsepline=false}}

\renewcommand\chapterpagestyle{highlights}

\usepackage{blindtext}% only for dummy text
\begin{document}
\chapter{Chapter 1}
Some text.
\blinddocument
\end{document}

更新（关于下面的评论）

您可以使用选项addheight、addhoffset、addvoffset、addwidth、和来height根据背景规则调整新定义的图层的位置和大小。hoffsetvoffsetwidth

如果要垂直放大标题背景规则，可以使用图层定义中的选项addvoffset和。addheight

上面第二个 MWE 的示例：

\DeclareNewLayer[
  background,
  oddpage,% not on even pages in two-sided documents
  head,
  addvoffset=2mm,% moves the layer 2mm down
  addheight=4mm,% enlarges the height of the layer by 4mm
  hoffset=0pt,
  width=\paperwidth,
  mode=picture,
  contents={\putLL{\tikz{
    \fill[shade,left color=blue!0,right color=blue!70]
      (0,0)rectangle(\the\layerwidth,\the\layerheight);
  }}
}
]{highlights.bg}

如果背景规则要从内文延伸到外纸边框，则不要更改hoffset并调整width：

\DeclareNewLayer[
  background,
  oddpage,% not on even pages in two-sided documents
  head,
  addvoffset=2mm,% moves the layer 2mm down
  addheight=4mm,% enlarges the height of the layer by 4mm
  %hoffset=0pt,% <- removed
  width=\paperwidth-1in-\hoffset-\oddsidemargin,% <- changed
  mode=picture,
  contents={\putLL{\tikz{
    \fill[shade,left color=blue!0,right color=blue!70]
      (0,0)rectangle(\the\layerwidth,\the\layerheight);
  }}
}
]{highlights.bg}

请注意，如果要在偶数页的双面文档中使用背景，则需要第二层。
