I have a PDF compiled with LaTeX that contains lists and quotes. My settings result in the lines not being on the same height when I view the PDF in double-page-mode as soon as I employ lists and quotes. E.g. I get this (from output-pages 6/7 of the MWE):
The line ›1. Lorem ipsum ...‹ on the right page is a bit too high. It should correspond to the line ›... Cum sociis natoque‹ on the left page. The vertical white space between the paragraph and the list that follows should be a bit larger. There are other occurences in the output-file.
As I have gathered from various questions, this has to do with lengths that include rubber-space or glue, such as \bigskipamount, to give TeX the maximum flexibility when building a page.
However, I would like to suppress the glue for this document regarding lists and quotes, to ensure that lines are, as far as this is achievable, always automatically on the same height when viewing the document in double-page-mode, without me having to check the vertical spacing and then adding or taking away a little.
This is what I have done so far:
\documentclass[paper=140mm:220mm]{scrbook}
\setkomafont{section}{\normalfont\bfseries}
\setkomafont{subsection}{\normalfont\bfseries}
\RedeclareSectionCommand[
beforeskip=-\baselineskip,
afterskip=.001\baselineskip
]{section}
\RedeclareSectionCommand[
beforeskip=-\baselineskip,
afterskip=.001\baselineskip
]{subsection}
\setlength{\bigskipamount}{12pt}
\setlength{\topsep}{9pt}
\setlength{\partopsep}{3pt}
\setlength{\parsep}{0pt}
\usepackage[indentfirst=false, noorphans, listvskip=true]{quoting}
\usepackage{lipsum}
\usepackage{enumitem}
\setlist{noitemsep}
\widowpenalty10000
\begin{document}
\raggedbottom
\chapter{One} \section{One} \lipsum[1-5]
\begin{quoting} \lipsum[1] \end{quoting}
\subsection{One} \lipsum[1-3]
\begin{itemize}\item{BlaBla} \item{\lipsum[1]} \item{BlaBla}
\item{\lipsum[1]}\item{BlaBla}\end{itemize}
\begin{quoting} \lipsum[1] \end{quoting}
\begin{quoting} \lipsum[1] \end{quoting}
\section{Two} \lipsum[1-5]
\begin{enumerate} \item{\lipsum[1]} \item{\lipsum[1]} \item{BlaBla}
\end{enumerate}
\begin{quoting} \lipsum[1] \end{quoting}
\end{document}
(The section-fontsizes are another topic. In the MWE example I set them so they don΄t affect the main issue further. quoting and its option listvskip=true allowed customizing the quote along the lines of the lists.)
These settings take out most instances, but ones depicted in the image still occur.
This means, to my understanding, that I haven’t tracked all instances of glue, yet. My question therefore regards the parameters of vertical spacing and the way to influence them when glue is involved:
Where is glue employed in lists and quotes, and how can I suppress it?
<natural> plus <stretch> minus <shrink>. This glue has a<natural>size that can stretch by<stretch>and shrink by<shrink>. If you don't want it to stretch or shrink, you can give it only its<natural>size. For example,\setlength{\bigskipamount}{12pt}would remove its ability to stretch and shrink. But you have to know which parameter you want to modify to remove this flexibility. – Phelype Oleinik Sep 09 '18 at 13:10\AtBeginEnvironment{itemize}{\bigskip}instead set the list parameters to be larger, latex goes to some effort not to for example add a double sized space if one list follows another but you are just unconditionally adding bigskipamount above and below each list even if there is already space there. – David Carlisle Sep 09 '18 at 13:37\bigskipat that point???? – David Carlisle Sep 09 '18 at 13:39\bigskipI tried to make the white space exactly a line high every time, however, it was not high enough in the image. I get the issue with\AtBeginEnvironmentand will try to reformulate the question to get rid of the confusion here. – Kubo Sep 09 '18 at 13:55bigskipin reformulating the question without making use of\bigskipI hope this is less confusing now. – Kubo Sep 09 '18 at 15:38\setlength{\parsep}{4.5pt}– David Carlisle Sep 09 '18 at 15:43\parsepto zero and included the image from the MWE-output. The old image was from another document with the same settings as the effects of the setting were easier to see there. – Kubo Sep 09 '18 at 16:44
