再現羅格朗橙皮書章圖風格

Question 1

更新重新定義\chapterlinesformat

從 KOMA-Script 版本 3.19 開始，\chapterlinesformat可以重新定義該命令以更改沒有前綴行的章節標題的佈局。現在可以為頁面標題設定不同的條目或使用章節標題指令的星號版本。多行的章節標題也是可能的。

以下範例用於open=any顯示它也適用於左手頁面。

\documentclass[open=any]{scrbook}[2015/10/03]
%\providecommand*\Ifthispageodd{\ifthispageodd}% needed up to and including KOMA-Script version 3.27, see https://komascript.de/faq_deprecatedif
\usepackage{blindtext}% dummy text
\usepackage{tikz}
\usetikzlibrary{positioning}

\RedeclareSectionCommand[
  beforeskip=1sp minus 1sp,
  afterskip=4\baselineskip plus .5ex minus .5ex
]{chapter}

\newcommand*\chapterimageheight{.5\paperwidth}% height of the chapter images
\newcommand*\chapterboxvoffset{1cm}% offset from text bottom to image bottom
\newcommand*\chapterboxhoffset{1cm}% offset from outer text margin to outer box border
\newcommand*\chapterboxwidth{\textwidth+1cm}% width of the chapter box 
\newcommand*\chapterboxsep{1em}% inner sep of the chapter box

\definecolor{ocre}{RGB}{243,102,25}
\colorlet{chapterbordercolor}{ocre}

\tikzset{
  chapterbox/.style={
    line width=2pt,rounded corners=20pt,draw=chapterbordercolor,
    fill=white,fill opacity=.5,text opacity=1,
    inner sep=\chapterboxsep,
    font=\usekomafont{disposition}\usekomafont{chapter}\huge
  }
}

\makeatletter
\newcommand*\@chapterimage{example-image.pdf}
\newcommand*\chapterimage[1]{\renewcommand*\@chapterimage{#1}}

\renewcommand\chapterlinesformat[3]{%
  \vspace*{\dimexpr-1in-\headsep-\headheight-\topmargin-1ex\relax}%
  \Ifthispageodd
    {\hspace*{\dimexpr-1in-\oddsidemargin\relax}%
      \tikzset{chapterboxpos/.style={
        anchor=south east,
        above left= \chapterboxvoffset and \chapterboxhoffset of bb.south east

    {\hspace*{\dimexpr\textwidth+1in+\oddsidemargin-\paperwidth\relax}%
      \tikzset{chapterboxpos/.style={

      \end{tikzpicture}%
    }%
  }%
}%
\makeatother

\begin{document}

\addchap*{Unnumbered Chapter without entry in table of contents}

\Blindtext[2]

\blindtext
\chapter[Numbered chapter with long title]{Numbered chapter that is really long and needs more than one line}
\chapterimage{chapter_head_2}% change the image
