语境：我正在使用该类scrbook。部分标题打印在空白页上，然后下一个内容从新页开始。
但是，KOMAscript 提供了\setpartpreamble[<position>]{<text>}允许在部分标题页上打印一些文本的命令。<position>要么o在标题上方插入文本，要么u在标题下方插入文本。
文档明确指出：
请注意你谁负责标题、序言和后续文本之间的空白。
问题：我想将插入在标题下方的序言“对齐底部”（后者是顶部对齐的）。但是，我既无法在\vspace*{\fill}序言文本的开头插入，也无法修改部分标题下方的空间，如下所示\renewcommand{\partheadendvskip}{\vskip\fill\newpage}。（我想象“标题和序言之间的空白由你负责“ 表示“\partheadendvskip在添加可预置项时不会被考虑”）
问题：如何将部分标题页中的序言底部对齐scrbook？
\documentclass[open any]{scrbook}
\usepackage{lipsum}
\usepackage{showframe}
\renewcommand{\partheadstartvskip}{\null}% removes vertical space before part title
\renewcommand{\partheadendvskip}{\vskip\fill\newpage}% no effect
\begin{document}
\setpartpreamble[u]{
%\vspace*{\fill}% <-- has no effet
This text comes after the part title, but on the same page.
I would like to ``flushbottom'' it, i.e.\@ I want it to be aligned with the bottom of the text area.
}
\part{Part title}
\lipsum
\end{document}
答案1
部分序言的内容设置在\parbox，因此齐平底部似乎是不可能的。
也许您正在使用scrlayer-scrpage页眉和页脚？那么您可以为部分页面定义一个新的页面样式，并使用添加到此页面样式的新图层插入您的序言。
\documentclass[open=any]{scrbook}
\usepackage{lipsum}
\usepackage{showframe}
\RedeclareSectionCommand[
beforeskip=0pt
]{part}
\usepackage{xpatch}
\usepackage{scrlayer-scrpage}
\DeclareNewLayer[
textarea,
foreground,
contents=\vfill\mypartpreamble
]{partpreamble}
\DeclareNewPageStyleByLayers{partpage}{partpreamble}
\ForEachLayerOfPageStyle{plain.scrheadings}{%
\AddLayersToPageStyle{partpage}{#1}%
}
\renewcommand\partpagestyle{partpage}
\makeatother
\newcommand\mypartpreamble{}
\newcommand\setmypartpreamble[1]{\def\mypartpreamble{#1}}
\xapptocmd{\partheademptypage}{\setmypartpreamble{}}{}{}
\begin{document}
\part{Part title without Preamble}
\lipsum
\setmypartpreamble{
This text comes after the part title, but on the same page.
I would like to ``flushbottom'' it, i.e.\@ I want it to be aligned with the bottom of the text area.
}
\part{Part title with Preamble}
\lipsum
\part{Part tile without Preamble}
\lipsum
\end{document}
包scrlayer-scrpage基于包scrlayer。
也可以只scrlayer在部分页面上使用特殊页面样式的包。那么您可能需要为页码声明一个额外的层。
示例没有任何其他用于页眉和页脚的包，但包含\pagestyle{headings}：
\documentclass[open=any,footlines=1]{scrbook}
%\providecommand*\Ifthispageodd{\ifthispageodd}% needed up to and including KOMA-Script version 3.27, see https://komascript.de/faq_deprecatedif
\usepackage{lipsum}
\usepackage{showframe}
\RedeclareSectionCommand[
beforeskip=0pt
]{part}
\pagestyle{headings}
\usepackage{xpatch}
\usepackage{scrlayer}
\DeclareNewLayer[
textarea,
foreground,
contents=\vfill\mypartpreamble
]{partpreamble}
\DeclareNewLayer[
foot,
background,
contents={\Ifthispageodd{\hfill\pagemark}{\pagemark\hfill}}
]{partpagenumber}
\DeclareNewPageStyleByLayers{partpage}{partpreamble,partpagenumber}
\renewcommand\partpagestyle{partpage}
\makeatother
\newcommand\mypartpreamble{}
\newcommand\setmypartpreamble[1]{\def\mypartpreamble{#1}}
\xapptocmd{\partheademptypage}{\setmypartpreamble{}}{}{}
\begin{document}
\part{Part title without Preamble}
\lipsum
\setmypartpreamble{
This text comes after the part title, but on the same page.
I would like to ``flushbottom'' it, i.e.\@ I want it to be aligned with the bottom of the text area.
}
\part{Part title with Preamble}
\lipsum
\part{Part tile without Preamble}
\lipsum
\end{document}
或者使用包fancyhdr和居中的页码：
\documentclass[open=any,footlines=1]{scrbook}
\usepackage{lipsum}
\usepackage{showframe}
\RedeclareSectionCommand[
beforeskip=0pt
]{part}
\usepackage{fancyhdr}
\pagestyle{fancy}
\usepackage{xpatch}
\usepackage{scrlayer}
\DeclareNewLayer[
textarea,
foreground,
contents=\vfill\mypartpreamble
]{partpreamble}
\DeclareNewLayer[
foot,
background,
contents={\hfill\pagemark\hfill}
]{partpagenumber}
\DeclareNewPageStyleByLayers{partpage}{partpreamble,partpagenumber}
\renewcommand\partpagestyle{partpage}
\makeatother
\newcommand\mypartpreamble{}
\newcommand\setmypartpreamble[1]{\def\mypartpreamble{#1}}
\xapptocmd{\partheademptypage}{\setmypartpreamble{}}{}{}
\begin{document}
\part{Part title without Preamble}
\lipsum
\setmypartpreamble{
This text comes after the part title, but on the same page.
I would like to ``flushbottom'' it, i.e.\@ I want it to be aligned with the bottom of the text area.
}
\part{Part title with Preamble}
\lipsum
\part{Part tile without Preamble}
\lipsum
\end{document}
