[latex]PGF 和 tikz中如何旋转图形的示例

tikz中如何旋转图形的示例:

测试旋转:\\

\begin{tikzpicture}[line width =2pt]

%原始图

\draw[dashed] (0,0) rectangle (2,2);

%旋转45度,取默认旋转点

\draw[rotate=45] (0,0) rectangle (2,2);

%旋转45度,指定旋转点(2,2)

\draw[rotate around={45:(2,2)},blue] (0,0) rectangle (2,2);

%辅助信息

\draw[fill=red] (0,0) circle (4pt);

\draw[fill=green](2,2) circle (4pt);

\node[below] (nodea) at (0,0){$(0,0)$};

\node[above] (nodeb) at (2,2){$(2,2)$};

\end{tikzpicture}

 

运行结果为:

 

旋转node也可一样设置
