Beamer 箭头指向特定位置

Question

我有以下图片：

我想用箭头画出细胞膜、线粒体和核膜，并在箭头的另一侧画出相应的细胞器/膜。

另一件重要的事情是，文本应该位于图的右侧

我曾尝试这么做，但却陷入困境。

代码：

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{positioning}
\begin{document}
\begin{frame}
\begin{tikzpicture}

\node (cellMembrane) {};
\node (mitochondrion) {};
\node (nuclearEnvelope) {};
\node (cell) [left=of cellMembrane] {\includegraphics[width=4cm]{pic.png}};


\node (a) [] at (cell.center) {};
\node (b) [] at (cellMembrane.center) {cell membrane};
\node (c) [] at (mitochondrion.center) {mitochondrion};
\node (d) [] at (nuclearEnvelope.center) {nuclear envelope};

\draw [ultra thick,magenta,<-] (a) to (b);
\draw [ultra thick,magenta,<-] (a) to (c);
\draw [ultra thick,magenta,<-] (a) to (d);

\end{tikzpicture}
\end{frame}
\end{document}

输出

更新

\documentclass{beamer}
\usepackage{tikz}
\usepackage{tikz-imagelabels}

\begin{document}
\begin{frame}

\begin{annotationimage}{width=6cm}{pic.png}
    \draw[annotation right = {cell membrane at 0.45}, thick, ->] to (0.75,0.45);
    \draw[annotation right = {nuclear envelope at 0.75}, thick, ->] to (0.6,0.64);
\end{annotationimage}

\end{frame}
\end{document}

输出：

问题是，它会在箭头周围添加白色边框或类似的东西。另一个问题是箭头周围出现了一个“白色”圆圈

白色圆圈

Answer 1

正如评论所说，该tikz-imagelabels软件包可能会有帮助。

如果您不喜欢箭头周围的光环，您可以像这样禁用它：

\documentclass{beamer}
\usepackage{tikz}
\usepackage{tikz-imagelabels}

\imagelabelset{
  annotation arrow/.style =
  {
    draw,
    ->,
    black,
    thick,
    shorten >= \borderthickness + \arrowdistance,
  },
}

\begin{document}
\begin{frame}

\begin{annotationimage}{width=6cm}{example-image-duck}
    \draw[annotation right = {with pizza at 0.45}] to (0.75,0.45);
    \draw[annotation right = {Cute duck at 0.75}] to (0.6,0.64);
\end{annotationimage}

\end{frame}
\end{document}
