LaTeX技巧686:定制精致的章节样式四

实现代码如下:

% load packages
\usepackage{tikz}
\usepackage[explicit]{titlesec}
%define colors
\definecolor{lightgray}{gray}{0.95}
\definecolor{darkgray}{gray}{0.5}
%define header image
\newcommand*\chapterlabel{}
\titleformat{\chapter}
{\gdef\chapterlabel{}
\normalfont\sffamily\Large\bfseries\scshape}
{\gdef\chapterlabel{\thechapter\ }}{0pt}
% begin the main image, shifted 5cm down from top
{\begin{tikzpicture}[remember picture,overlay]
% add grey filled bar, 4cm high, full page wide.
\node[yshift=-5cm] at (current page.north west)
{\begin{tikzpicture}[remember picture, overlay]
\draw[fill=darkgray] (0,0) rectangle
(\paperwidth,4cm);
;
% add the title, shifted to be centered in bar
\node[anchor=east,yshift=2cm,xshift=0.9\paperwidth, text width=1.05\textwidth]{\color{lightgray}\nohyphens{\huge{#1}}} ;
% add rounded rectangle on top right, contains chapter number
\node[draw, anchor=east,yshift=4cm,xshift=0.98\paperwidth,rectangle,
rounded corners=10pt,inner sep=6pt,
fill=lightgray]
{\color{darkgray}Chapter \chapterlabel};
\end{tikzpicture}
};
\end{tikzpicture}
}
%adjust spacing for correct alignment of following text
\titlespacing*{\chapter}{0pt}{50pt}{-10pt}
