在 marginpar 中带有固定图像的框架环境

Question

我想在 中获得下面的精确输出LaTeX。但无法修复它以及如何在每个example环境的 marginpar 中设置图像。

我的 MWE 是：

\documentclass{book}
\usepackage{tcolorbox}
\usepackage[tikz]{mdframed}
\makeatletter
\definecolor{examplecolor}{cmyk}{0.7,0.63,0.07,0}
\definecolor{examplecolortext}{cmyk}{1,0.2,0,0}
\tikzset{
  my example style/.style={font=\bfseries, anchor=west, align=left,     text=examplecolor},
}
\newcounter{example}[chapter]
\renewcommand{\theexample}{\arabic{example}}
\newenvironment{example}[1][]{
  \stepcounter{example}%
  \ifstrempty{#1}%
  {\mdfsetup{%
      frametitle={%
        \begin{tikzpicture}
          \node [my example style, text width=.2\linewidth] {\strut     Example~\theexample};
        \end{tikzpicture}%
      }%
    }%
  }%
  {\mdfsetup{%
      frametitle={%
        \begin{tikzpicture}
          \node (some node) [my example style, text width=.2\linewidth,     inner xsep=0pt, inner ysep=-10pt] {\strut Example~\theexample};
          \node [my example style, text=examplecolortext, text     width=.75\linewidth] {\strut\hspace*{-35pt}#1};
        \end{tikzpicture}%
      }%
    }%
  }%
  \mdfsetup{%
    frametitlebackgroundcolor=examplecolortext,
    linecolor=white,%
    linewidth=0pt,
    frametitlerule=true,
    frametitlerulewidth=2.5pt,
  }\relax
  \begin{mdframed}%
}{%
  \end{mdframed}%
}
\makeatother

一种可能性是使用tcolorbox（根据您的需要调整设置）：

代码：

\documentclass{book}
\usepackage{graphicx}
\usepackage{changepage}
\usepackage[many]{tcolorbox}
\usepackage{lipsum}

\definecolor{titlecolor}{RGB}{0,135,221}
\definecolor{titleheadcolor}{RGB}{107,88,168}
\definecolor{titlebg}{RGB}{249,252,98}
\definecolor{framebg}{RGB}{252,254,197}

\newtcbtheorem{myexample}{Example}{
  breakable,
  enhanced,
  freelance,
  frame empty,
  interior empty,
  toptitle=5pt,
  bottomtitle=5pt,
  check odd page,
  overlay={
  \ifoddpage
      \node[overlay,anchor=west] 
        at ([xshift=\marginparsep]title.east)
        {\includegraphics[height=22pt]{image-1}};
  \else
      \node[overlay,anchor=east] 
        at ([xshift=-\marginparsep]title.west)
        {\includegraphics[height=22pt]{image-1}};
  \fi
  },
  title code={
    \fill[titlebg] 
      (title.south west) {[rounded corners=10pt] -- 
      (title.north west) --
      (title.north east)} --
      (title.south east) --
      (title.south west);
    \draw[white,line width=3pt]
      (title.south west) -- (title.south east);  
  },
  segmentation code={
    \draw[white,line width=3pt]
      (segmentation.west) -- (segmentation.east);  
  }
  coltitle=titlecolor,
  colback=framebg,
  fonttitle=\sffamily,
  coltitle=titleheadcolor,
  boxrule=0pt,
  description color=titlecolor
}{exa}

\newcommand\SolExp{%
  \par\bigskip\color{titlecolor!90}\textsc{solution}\hfill\textsc{explanation}\hfill\null%
  \tcblower
}

\begin{document}

\begin{myexample}{Writing expressions from world descriptions}{expressions}
\lipsum[4]
\SolExp

\end{myexample}
\lipsum[1-4]
\begin{myexample}{Writing expressions from world descriptions and a longer title spanning more than one line}{longer}
\lipsum[4]
