Modifying list of tables/images

Question

I'd like to customize the list of figures and tables with a similar design to this:

Modifying mini-toc content

Does somebody know how to do a similar design for a list of tables/images?

Answer 1

titletoc package can also be used to customize the list of figures and tables. From the documentation of \dottedcontents and \titlecontents commands:

"section" is the section name without backslash: part, chapter, section, etc. figure and table are allowed, too. (The backlash is omitted because we are dealing with the concept and not the \part, \section, etc. macros themselves. Furthermore, figure and table are environments.)

You can easily adapt the code in the mentioned answer to get the desired result:

\titlecontents{figure}
  [0em]{\vspace*{2\baselineskip}}
  {\parbox{4.5em}{%
    \hfill\Huge\sffamily\bfseries\color{myred}\thecontentspage}%
   \vspace*{-2.3\baselineskip}\leftbar\textsc{\small Figure~\thecontentslabel}\\\sffamily}
  {}{\endleftbar}

---

EDIT 1:

For further customization, you can extract the value of current chapter from the macro \thecontentslabel, e.g.:

\makeatletter
\titlecontents{figure}
  [0em]{\vspace*{2\baselineskip}}
  {\parbox{4.5em}{%
    \hfill\Huge\sffamily\bfseries\color{myred}\thecontentspage}%
   \vspace*{-2.3\baselineskip}\leftbar 
   \textsc{\small \chaptername~\expandafter\@car\thecontentslabel\@nil\ // %
     Figure~\thecontentslabel}\\\sffamily}
  {}{\endleftbar}
\makeatother

---

EDIT 2:

You can insert any kind of material into a lof via \addtocontents. E.g., you can define a command \updatemylof invoked after a \chapter to insert a title into your lof which is formatted like a section. Maybe you can customize this approach to your needs. Code:

\documentclass{book}
\usepackage{xcolor,framed,titletoc,lmodern}

\definecolor{myred}{RGB}{127,0,0}
\definecolor{myyellow}{RGB}{169,121,69}

\renewenvironment{leftbar}{%
  \def\FrameCommand{%
    \hspace{6em}%
    {\color{myyellow}\vrule width 2pt depth 6pt}%
    \hspace{1em}%
  }%
  \MakeFramed{\parshape 1 0cm \dimexpr\textwidth-6em\relax\FrameRestore}\vskip2pt\relax
  }
 {\endMakeFramed}

\titlecontents{chapter}
  [0em]{\vspace*{2\baselineskip}}
  {\parbox{4.5em}{%
    \hfill\Huge\sffamily\bfseries\color{myred}\thecontentspage}%
   \vspace*{-2.3\baselineskip}\leftbar
   \textsc{\small\chaptername~\thecontentslabel}\\\sffamily}
  {}{\endleftbar}
\titlecontents{section}
  [8.4em]
  {\sffamily\contentslabel{3em}}{}{}
  {\hspace{0.5em}\nobreak\itshape\color{myred}\contentspage}
\titlecontents{subsection}
  [8.4em]
  {\sffamily\contentslabel{3em}}{}{}  
  {\hspace{0.5em}\nobreak\itshape\color{myred}\contentspage}

\titlecontents{figure}
  [0em]{\vspace*{2\baselineskip}}
  {\parbox{4.5em}{%
    \hfill\Huge\sffamily\bfseries\color{myred}\thecontentspage}%
   \vspace*{-2.3\baselineskip}\leftbar
   \textsc{\small Figure~\thecontentslabel}\\\sffamily}
  {}{\endleftbar}

\newcommand*\updatemylof{%
  \addtocontents{lof}{\protect\section*{Chapter~\thechapter}}%
}
