line-spacingspacingtable of contents
I am using the book documentclass and have a list of figures. After much trouble I noticed that there is a blank line to separate figures that are in different chapters, but not if they are within the same chapter. Since I changed the numbering of my figures to be {1, 2, 3, etc.} instead of {2.1, 2.2, 3.1, etc.} this looks silly and I'd rather have a blank line between each figure, no matter what.
How do I do that?
Similar:
You can insert part, chapter or any other references in a table of contents, list of figures or list of tables with \addcontentsline{ext}{type}{text} where ext is the extension of auxiliar file (usually toc, lof, lot), type specifies type of contents and text what you want to be shown in the list. Here you have a simple example.
\documentclass{book}
\begin{document}
\tableofcontents
\listoffigures
\part{A}
\addcontentsline{lof}{part}{Part A}
\chapter{A1}
\addcontentsline{lof}{chapter}{Chapter A1}
\section{A11}
\begin{figure}
\caption{FigA1}
\end{figure}
\begin{figure}
\caption{FigA2}
\end{figure}
\chapter{A2}
\addcontentsline{lof}{chapter}{Chapter A2}
\begin{figure}
\caption{FigA21}
\end{figure}
\part{B}
\end{document}
The result is
The package tocloft allows you to define or change the format of a table of contents but I've never used it. You can read its introduction and will learn how ToC works in LaTeX.
EDIT: You can avoid typing twice chapter names and part names if you declare your own commands. Look at the example \mypart command contains \part and \addcontentsline. This way, parts and chapters in lof will look the same as in toc.
\documentclass{book}
\newcommand{\mypart}[1]{%
\part{#1}
\addcontentsline{lof}{part}{\thepart\hspace{1em}#1}
}
\newcommand{\mychapter}[1]{%
\chapter{#1}
\addcontentsline{lof}{chapter}{\numberline{\thechapter}#1}
}
\begin{document}
\tableofcontents
\listoffigures
\mypart{A}
\mychapter{A1}
\section{A11}
\begin{figure}
\caption{FigA1}
\end{figure}
\begin{figure}
\caption{FigA2}
\end{figure}
\mychapter{A2}
\begin{figure}
\caption{FigA21}
\end{figure}
\mypart{B}
\end{document}
A patch to correct for this behaviour is provided by the etoolbox package. The default \chapter inserts a 10pt vertical gap between chapter breaks in the LoF and LoT. Merely add a similar gap as part of the macro \@chapter to the LoA:
\documentclass[12pt]{book}
\usepackage{etoolbox}
\makeatletter
\patchcmd{\@chapter}% <cmd>
{\chaptermark{#1}}% <search>
{\chaptermark{#1}%
\addtocontents{loa}{\protect\addvspace{10\p@}}}% replace
{}{}% <success><failure>
\makeatother
\usepackage[chapter]{algorithm}% http://ctan.org/pkg/algorithms
\begin{document}
\tableofcontents
\listofalgorithms
\chapter{A chapter}
\begin{algorithm}\caption{An algorithm}\end{algorithm}
\begin{algorithm}\caption{An algorithm}\end{algorithm}
\chapter{A chapter}
\begin{algorithm}\caption{An algorithm}\end{algorithm}
\begin{algorithm}\caption{An algorithm}\end{algorithm}
\end{document}
The original \@chapter command contains:
%...
\chaptermark{#1}%
\addtocontents{lof}{\protect\addvspace{10\p@}}%
\addtocontents{lot}{\protect\addvspace{10\p@}}%
%...
The \patchcmd searches for \chaptermark{#1} in \@chapter and replaces it with
\chaptermark{#1}%
\addtocontents{loa}{\protect\addvspace{10\p@}}%
effectively inserting the necessary chapter-wise gap in the LoA.
Make sure to load any package that affects the sectional unit \chapter after performing this patch. This is especially true if you use hyperref and minitoc. Other sectional packages like titlesec would not be compatible with the above patch.

In the book class there's an internal macro
\@chapterthat's adding the space by this line:You could redefine this macro. Alternatively, you could disable
\addvspacein the list of figures, for instance byThe effect should end with the list of figures, but of course you could group it to limit the scope.
If you disabled it you could use an environment or a declaration of the
setspacepackage, to get more space between the lines of the list of figures. Or you just use\linespreadlocally:
