ラップされた図形の水平位置を調整するにはどうすればよいですか?

Question

円形の図の周りにテキストを折り返しました。テキストを円形に折り返した図をページの中央に移動して、図の位置を水平に調整する必要があります。

\hspace*{-5cm}\includegraphics... が動作しません。どうすればいいですか?

\documentclass{article}
\usepackage{lipsum}
\usepackage{graphicx,wrapfig}
\begin{document}

\null\hfill\smash{
\raisebox{\dimexpr-\height+\baselineskip}{%
\includegraphics[width=2in]{magmag2.png}}}%
\par\vspace*{\dimexpr-\baselineskip-\parskip}% 
\parshape 12 0pt 0.7\textwidth
0pt \dimexpr0.5\textwidth+4.5\baselineskip\relax
0pt \dimexpr0.5\textwidth+3.75\baselineskip\relax
0pt \dimexpr0.5\textwidth+3.25\baselineskip\relax
0pt \dimexpr0.5\textwidth+3.00\baselineskip\relax
0pt \dimexpr0.5\textwidth+3.0\baselineskip\relax
0pt \dimexpr0.5\textwidth+3.20\baselineskip\relax
0pt \dimexpr0.5\textwidth+3.5\baselineskip\relax
0pt \dimexpr0.5\textwidth+4.25\baselineskip\relax

Answer 1

これは、ある程度の余裕を持たせるために、穴の半径を 1.1 インチとしています。lipsum はハイフンで区切るのが難しいことに注意してください。

pgfmath を使用して設定しようとしました\holeshapeが、は使用できません\edef。一方、定義をファイルに書き込んで読み戻すことはできるはずです。

\def\holeshape{{14.375}% h center

\begin{document}
By using \verb|\baselineskip| as the scale, one can use $\sqrt{r^2-n^2}$ for $n=0,1,\dots$
to compute the offset startng at the center.

radius = \pgfmathparse{1.1in/\baselineskip}\pgfmathresult\par
text width = \pgfmathparse{\textwidth/\baselineskip}\pgfmathresult

\noindent\begin{tikzpicture}[overlay,baseline=(origin)]
  \coordinate (origin) at (0,3pt);% ad hoc fudge factor
  \draw (0.5\textwidth,-7\baselineskip) circle[radius=1in];
\end{tikzpicture}%
\shapepar[\baselineskip]{\holeshape}\lipsum[1]

\end{document}
