透明背景可实现更好的包裹图表

Question

我已经生成了以下内容使用 Tikz。然后我想用文本将其包裹起来，如（红色框）：

有没有办法实现这一点？知道流程图（单独生成）以 pdf 格式包含在我的主文件中

更新：在第一条评论之后，我认为最好将流程图代码包含在主代码中。这是一个 MWE：

\documentclass{article}
\usepackage{ulem,tikz,amsmath, amssymb,bm,color}
\usepackage[english]{babel}
\usepackage{lipsum}
\usepackage[margin=0cm,nohead]{geometry}
\usetikzlibrary{shapes,arrows}
\usepackage{pgfplots}
\usepackage{wrapfig}
% needed for BB
\usetikzlibrary{calc}
\usetikzlibrary{shapes,arrows}

\tikzstyle{line} = [draw, -latex']
\begin{document}
\lipsum[5]
\begin{wrapfigure}{r}{0.5\textwidth} 
  \begin{center}
\begin{tikzpicture}[node distance =1.5cm,auto]

% Place nodes
    \node [draw,rounded corners] (node1) {a};
    \node [draw,rounded corners, below of=node1] (node2) {b};
    \node [draw,rounded corners, below of=node2] (node3) {c};
   \node [ below of=node3] (Inter1){};
    \node [draw,rounded corners, right of=Inter1,node distance =2.5cm] (node4) {d};
    \node [draw,rounded corners, right of=node4,node distance =3.5cm] (node5) {d};
    \node [draw,rounded corners, left of=Inter1,node distance =2.5cm] (node6) {d};
    \node [draw,rounded corners, left of=node6,node distance =3.5cm] (node7) {d};
    \node [ below of=node7] (Inter2){};
    \node [draw,rounded corners, right of=Inter2] (node8) {d};
    \node [draw,rounded corners, left of=Inter2] (node9) {d};
    \node [ below of=node8] (Inter3){};
%     % Draw edges
    \path[line] (node1) -- (node2);
    \path [line] (node2) -- (node3);
   \path [line] (node3) --++(-90:8mm)-| (node4.north);
   \path [line] (node3)  --++(-90:8mm)-|  (node5.north);
     \path [line] (node3)  --++(-90:8mm)-|  (node6.north);    
    \path [line] (node3) --++(-90:8mm)-|  (node7.north);
    \path [line] (node7)--++(-90:8mm)-| (node8.north);
    \path [line] (node7) --++(-90:8mm)-|  (node9.north);

\end{tikzpicture}\caption{Example graphic made with tikz.}
  \end{center}
\end{wrapfigure}
\end{document}

Answer 1

扩展我在评论中给出的想法，下面的代码显示了一种实现此目的的可能方法：

\documentclass{article}
\usepackage{graphicx}
\usepackage{tikz}
\usepackage[margin=2.5cm,a4paper]{geometry}
\usepackage{lipsum}
\newcommand\smashfigure[1]{%
  \marginpar{\llap{%
    \includegraphics[width=0.6\textwidth]{#1}
  }}
}
\begin{document}
\smashfigure{tree}
\parshape12
0cm 11.2cm
0cm 11.2cm
0cm 11.2cm
0cm 11.2cm
0cm 11.2cm
0cm 11.2cm
0cm 7.2cm
0cm 7.2cm
0cm 6.2cm
0cm 6.2cm
0cm 6.2cm
0cm \textwidth
\lipsum[1]

\end{document}

但是，恕我直言，输出非常丑陋：
