如何原地旋转盒子

Question

以下 LaTeX 代码说明了我的问题。是否可以在不执行否定操作的情况下获得我想要的结果\hskip，因为我想要一个简单的通用解决方案是将盒子旋转到任意角度（中心原点）但将其保持在原位？

理想的解决方案是允许我这样做：

{a}\somespecialrotate[origin=c]{\anyangle}{b}

\documentclass{article}
\usepackage{graphicx}
\usepackage{xcolor}
\begin{document}
\newsavebox\bxa
\newsavebox\bxb
\huge
\savebox\bxa{\color{red}\rule{1cm}{1cm}}
\savebox\bxb{\color{black}\rule{1cm}{1cm}}
\usebox\bxa\rotatebox[origin=c]{45}{\usebox\bxb}This is what I do not want\par
\usebox\bxa\hskip-0.25cm\rotatebox[origin=c]{45}{\usebox\bxb}This is what I DO want
\end{document}

Answer 1

adjustbox使用v0.8 中的可以轻松完成此操作2011/11/14。它提供原始宽度，\Width可用于将旋转的内容居中（其余部分在左侧和右侧重叠）或计算旋转内容应向左重叠的量，即您所说\hskip的。当前宽度始终为\width，因此lap=-.5\width+.5\Width将使旋转的内容向左重叠。adjustbox有关详细信息，请参阅手册。

使用旧版本的 ，如果您自己对内容进行装箱，则adjustbox可以用 代替\Width。\wd\bxb如果您不想使用adjustbox，而是自己动手，则需要对原始内容（\bxb）和旋转后的内容（例如\bxc）进行装箱，然后使用\mbox{\hskip\dimexpr -.5\wd\bxb+.5\wd\bxc\relax\usebox\bxc}排版该框。

\documentclass{article}
\usepackage{adjustbox}[2011/11/14]
\usepackage{xcolor}
\begin{document}
\newsavebox\bxa
\newsavebox\bxb
\huge
\savebox\bxa{\color{red}\rule{1cm}{1cm}}
\savebox\bxb{\color{black}\rule{1cm}{1cm}}
\usebox\bxa\rotatebox[origin=c]{45}{\usebox\bxb}This is what I do not want\par
\usebox\bxa\hskip-0.25cm\rotatebox[origin=c]{45}{\usebox\bxb}This is what I DO want

\usebox\bxa\adjustbox{origin=c,angle=45,center=\Width}{\usebox\bxb}This is with the original width

\usebox\bxa\adjustbox{origin=c,angle=45,lap=-.5\width+.5\Width}{\usebox\bxb}This is with overlapping only at the left

% As macro:
\newcommand{\somespecialrotate}[2][]{\adjustbox{#1,angle={#2},lap=-.5\width+.5\Width}}

\usebox\bxa\somespecialrotate[origin=c]{15}{\usebox\bxb}This is some text\par
\usebox\bxa\somespecialrotate[origin=c]{25}{\usebox\bxb}This is some text\par
\usebox\bxa\somespecialrotate[origin=c]{35}{\usebox\bxb}This is some text\par
\usebox\bxa\somespecialrotate[origin=c]{45}{\usebox\bxb}This is some text\par
\usebox\bxa\somespecialrotate[origin=c]{55}{\usebox\bxb}This is some text\par
\usebox\bxa\somespecialrotate[origin=c]{65}{\usebox\bxb}This is some text\par
\usebox\bxa\somespecialrotate[origin=c]{75}{\usebox\bxb}This is some text\par
\usebox\bxa\somespecialrotate[origin=c]{85}{\usebox\bxb}This is some text\par
\usebox\bxa\somespecialrotate[origin=c]{95}{\usebox\bxb}This is some text\par

这里有一个graphicx仅使用一个临时盒子寄存器的解决方案：

\documentclass{article}
\usepackage{graphicx}
\usepackage{xcolor}

\makeatletter
\newcommand{\somespecialrotate}[3][]{%
    \begingroup
    \sbox\@tempboxa{#3}%
    \@tempdima=.5\wd\@tempboxa
    \sbox\@tempboxa{\rotatebox[#1]{#2}{\usebox\@tempboxa}}%
    \advance\@tempdima by -.5\wd\@tempboxa
    \mbox{\hskip\@tempdima\usebox\@tempboxa}%
    \endgroup
}
\makeatother

\begin{document}
\huge
{\color{red}\rule{1cm}{1cm}}\somespecialrotate[origin=c]{45}{\color{black}\rule{1cm}{1cm}}This is some text\par
{\color{red}\rule{1cm}{1cm}}\somespecialrotate[origin=c]{30}{\color{black}\rule{1cm}{1cm}}This is some text\par

\end{document}

较低的部分：

这里的角度为 0,5,...,180：

使用\makebox无需旋转即可获得相同的宽度：

\documentclass{article}
\usepackage{graphicx}
\usepackage{xcolor}
\newsavebox\bxa
\newsavebox\bxb
\makeatletter
\newcommand\somespecialrotate[3][]{%
  \sbox\bxa{#3}\makebox[\wd\bxa]{\rotatebox[#1]{#2}{#3}}}
\makeatother
\def\RotateBox#1#2{\sbox{\bxa}{#2}\sbox\bxb{\rotatebox[origin=c]{#1}{#2}}%
  \makebox[\wd\bxa]{\usebox\bxb}\kern\dimexpr(\wd\bxb-\wd\bxa)/2\relax}
\begin{document}
\huge
\color{red}\rule{1cm}{1cm}%
\rotatebox[origin=c]{45}{\color{black}\rule{1cm}{1cm}}This is what I do not want\par
\rule{1cm}{1cm}%
\RotateBox{45}{\color{black}\rule{1cm}{1cm}}This is what I DO want\par

\color{red}\rule{1cm}{1cm}%
\somespecialrotate[origin=c]{45}{\color{black}\rule{1cm}{1cm}}

\end{document}
