How Can I Produce a Fancy Chapter Heading like This One?

QUESTION

I just found some chapter headings that are really nice: example page

But I can't exactly figure out how to extend the rule off the margin and put the figure on the page before the chapter and the caption on the next (chapter heading) page. (Some tip on the footer would be nice, too).

The layout of the other pages look pretty much the same:

ANSWER

Here's a solution: using the xparse package I defined a new command \ChapIma with one optional argument and two mandatory arguments; the optional argument will be the text used for the ToC; the first mandatory argument is the text for the document, and the third mandatory argument is the name of the file containing the corresponding image.

The titlesec package was used to customize the chapter title format.

I also defined another command \Caption, which behaves as the standard caption, but writes the text in the space reserved for marginal notes. This command must be invoked somewhere in the first line of text of the chapter.

The caption package was used to customize the caption in the marginal notes (suppressing the label).

The lettrine package was used to produce the drop cap.

I used the fancyhdr package (I couldn't make titlesec's pagestyles option behave well, so I had to use fancyhdr) to redefine the plain page; I also defined the page style for other pages.

\documentclass[twoside]{book}
\usepackage{xparse,ifthen}
\usepackage[calcwidth]{titlesec}
\usepackage{changepage}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{fancyhdr}
\usepackage{marginnote}
\usepackage{lettrine}
\usepackage{lipsum}

\newlength\mylen

\DeclareDocumentCommand\ChapIma{omm}
  {\let\cleardoublepage\relax
    \ifthenelse{\isodd{\value{page}}}
      {\mbox{}\clearpage}{\mbox{}\clearpage\mbox{}\clearpage}%
    \resizebox{.9\textwidth}{.9\textheight}{\includegraphics{#3}}
    \mbox{}\thispagestyle{empty}\clearpage
    \IfNoValueTF{#1}{\chapter{#2}}{\chapter[#1]{#2}}
  }

\DeclareDocumentCommand\Caption{om}
  {\marginnote{\parbox{\marginparwidth}{%
      \captionsetup[figure]{labelformat=empty}
    \IfNoValueTF{#1}{\captionof{figure}{#2}}{\captionof{figure}[#1]{#2}}
      }%
    }%
  }

\titleformat{\chapter}[display]
  {\Huge\normalfont\sffamily}{}{2pc}  
  {\setlength\mylen{0pt}%
    \addtolength\mylen{\marginparwidth}%
    \addtolength\mylen{\marginparsep}\raggedleft
  }
  [\vspace{-20pt}%
   {%
      \begin{adjustwidth}{}{-\mylen}
        \makebox[\linewidth][r]{%
          \rule{\dimexpr\titlewidth+\mylen\relax}{0.4pt}%
        }%
      \end{adjustwidth}%
   }%
  ]
\titlespacing*{\chapter}{0pt}{1cm}{7cm}

\renewcommand\chaptermark[1]{\markboth{#1}{}}

\fancypagestyle{plain}{%
  \fancyhf{}
  \fancyfoot[OR]{\sffamily\small\MakeUppercase{\leftmark}~~\oldstylenums{\thepage}}
  \renewcommand{\headrulewidth}{0pt}
  \renewcommand{\footrulewidth}{0pt}
  \fancyfootoffset[OR]{\dimexpr\marginparsep+\marginparwidth\relax}
}

\fancyhf{}
\fancyfootoffset[OR]{\dimexpr\marginparsep+\marginparwidth\relax}

\fancyfoot[EL]{\small\sffamily\oldstylenums{\thepage}~~\MakeUppercase{\rightmark}}
\renewcommand{\headrulewidth}{0pt}
\renewcommand{\footrulewidth}{0pt}
\pagestyle{fancy}

\renewcommand\chaptermark[1]{\markboth{#1}{}}
\renewcommand\sectionmark[1]{\markright{#1}}

\begin{document}

\tableofcontents

\ChapIma{Preface}{ctanlion}
\lettrine{T}{his} is some initial text\Caption{This is the caption for the figure; this is just some test text}
\lipsum[1-5]
\ChapIma{Introduction}{ctanlion}
\lipsum[1]
\section{Qu'ran manuscripts}
\lipsum[1-14]

\end{document}

Here's an image of four pages of the resulting document:
