在这种情况下，如何在不使用绘制命令的情况下旋转椭圆？
\documentclass{beamer}
\usepackage[T1]{fontenc}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\node[anchor = south west, inner sep = 0] (image) {\includegraphics[width = 0.53\paperwidth, height = 15cm, keepaspectratio] {image}};
\begin{scope}[shift={(image.south west)},x={(image.south east)},y={(image.north west)}]
\foreach[count=\i] \mypath in {
{(0.10,0.55) rectangle (0.25,0.65)
(0.55,0.20) ellipse (0.10 and 0.05)}
}{
\filldraw<\i>[white,opacity=0.75,even odd rule] (0,0) rectangle (1,1) \mypath;
\draw<\i>[blue, thick] \mypath;
}
\end{scope}
\end{tikzpicture}
\end{document}
非常感谢，哈利
