\rotatebox{} 不进行水平平移

Question

我想picture围绕指定点旋转环境中的元素。我尝试过\rotatebox{}这样做。此网页描述了什么\rotatebox{}：

1. 围绕基线起点 ( graphics) 或指定点 ( grahpicx) 旋转元素。
2. 水平平移元素，使得新边界框的左边缘与旋转之前的边界框的左边缘重合。

第二步造成了麻烦，因为我只想旋转元素，而不是随后水平平移它。请考虑以下示例：

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

\begin{document}
\setlength{\unitlength}{1cm}
\begin{picture}(3,3)
\put(1,1){{\color{red}\circle*{0.1}}}
\put(1,1){\parbox[t]{2cm}{\raggedright{text that is wrapped}}}
\put(2,2){{\color{blue}\circle*{0.1}}}
\put(2,2){\rotatebox[origin=lB]{60}{\parbox[t]{2cm}{text that is wrapped and rotated}}}
\end{picture}
\end{document}

可以看出，蓝点不再与旋转文本的基线起始位置对齐。这是由于步骤 #2 中的平移（导致元素向右移动）。如何旋转元素以使基线起始（或更一般地指指定的旋转点）不移动？

编辑：我希望能够将旋转点指定为任意点，而不仅仅是基线起点位置。graphicx的版本\rotatebox{}允许这样做：

\rotatebox[x=TeX dimension,y=TeX dimension]{...}

Answer 1

作为对编辑的回应，这里是另一个可能有效的选项。它是

\rotbox[pole1,pole2]<x-offset,y-offset>{angle}{content}

pole1内容被旋转并放置在与交点的指定偏移处pole2。请参阅xcoffins 文档第 2 页提供了预定义极点的列表（对于棺材，我刚刚为预先存在的功能做了一个包装）。极点和偏移都是可选的，并且具有默认值（您可以更改），即极点的排版材料的左边缘和基线，以及偏移的零。这是我第一次尝试制作棺材，所以我可能在某个地方弄混了。

（旧答案）我认为这可能是你想要的：

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

\begin{document}
\setlength{\unitlength}{1cm}
\begin{picture}(3,3)
\put(1,1){{\color{red}\circle*{0.1}}}
\put(1,1){\parbox[t]{2cm}{\raggedright{text that is wrapped}}}
\put(2,2){{\color{blue}\circle*{0.1}}}
\put(2,2){\turnbox{60}{\parbox[t]{2cm}{text that is wrapped and rotated}}}
\end{picture}
\end{document}
