帶有新部分的頁面上頁首 (KomaScript) 中帶有顏色漸變的框

Question

不幸的是，我不太明白想要的結果應該是什麼。但我建議為標題背景定義一個新圖層：

\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}

然後您可以在新定義的頁面樣式的開頭新增此圖層：

\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，如果文件中的每個部分都應從新的奇數頁開始，那麼您可以scrreprt使用選項切換到類別open=right。因此，這裡有一個附加建議，假設 pagestyle使用與 pagestyle和新圖層highlights相同的圖層：plain.scrheadingshighlight.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（關於下面的評論）

您可以使用選項addheight、addhoffset、addvoffset、addwidth、height、hoffset和voffset來width調整具有背景規則的新定義圖層的位置和大小。

如果要垂直放大標題背景規則，可以在圖層定義中使用選項addvoffset和。addheight

上面第二個 MWE 的範例：

\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}

如果背景線應從內部文字延伸到外部紙張邊框，請勿變更hoffset和調整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}

請注意，如果背景也應在偶數頁的雙面文件中使用，則需要第二層。
