如何让页眉、章节标题和图形扩展到页边距？

Question

我对以下页面布局感兴趣。

1. 如何在页边距中添加页眉（最多到页边距）
2. 是否可以从页边距开始章节标题
3. 如何设置图形占据的边距。

我可以制作如下所示的 MWE

    \documentclass[12pt,a4paper]{scrbook}

\usepackage[demo]{graphicx}

\usepackage[calcwidth]{titlesec}

%\titleformat{\section}[leftmargin]
%{\normalfont
%\sffamily\bfseries\filleft}
%{}{0pt}{}
%\titlespacing{\section}
%{4pc}{1.5ex plus .1ex minus .2ex}{1pc}

\newlength\mylen
\setlength\mylen{\dimexpr\oddsidemargin+1in+\hoffset\relax}

\titleformat{\section}
  {\normalfont\Large\bfseries}
  {\llap{\hspace*{-\mylen}\thesection\hfill}}{0em}{}
  [{\makebox[\linewidth][l]{%
    \hspace*{-\mylen}\rule{\dimexpr\textwidth+\mylen\relax}{1pt}}}]

%titleps is alternate for fancyhdr
%
\usepackage{titleps}

%\newpagestyle{main}[\small\sffamily]{
\newpagestyle{main}{
\widenhead[4pc][0pt]{4pc}{0pt} %for scrbook
%\widenhead[6pc][0pt]{0pt}{6pc} %for scrbook
%\widenhead[0pt][6pc]{6pc}{0pt} %for scrartcl
\headrule
\sethead
[\textbf{\thepage}]
[\textsl{Title of the Book}]
[]
{}
{\textsl{\chaptertitle}}
{\textbf{\thepage}}
}
\pagestyle{main}

\renewpagestyle{plain}[\small\sffamily]{
%\footrule
%\setfoot[\textbf{\thepage}]
\setfoot
[]
[]
[]
{}
{}
%{\textbf{\thepage}}
{}
%
\sethead
[\textbf{\thepage}]
[\textsl{Title of the Book}]
[]
{}
{}
{\textbf{\thepage}}
}



\begin{document}

\chapter{Chapter title}

我想将图形位置改为边距......

可能的解决方案 将图表并排摆放，溢出到外边距

Answer 1

此次修复包括几点：

1）\usepackage{calc}

2）新的标题定义使其左对齐：

\newcommand\mycaption[1]{\caption{%
  \leftskip-\mylen#1\protect\rule{\textwidth-\mylen}{0in}}}

3）\leftskip图形环境的边距

\begin{figure}[hb]
\setlength\leftskip{\leftskip-\mylen}
\includegraphics[width=0.2\linewidth]{}
\mycaption{Figure caption}
\end{figure}

警告：我没有修复第 3 页上现有的边距问题。
