使用 beamer 将 TikZ 云移动到更好的位置

我正在尝试操纵 TikZ 的精确位置cloud，但我不确定我是否做了任何努力。

正如您在上述图片中看到的，项目之间的空间并不美观。所以我尝试将其添加到itemize环境之外。但它似乎没有遵循我的命令。我使用的代码是

对此有什么想法吗？

噢，敲击更快。我基本上做了同样的事情，但是把它变成了一个带有参数的宏[angle]{content}：

代码

\documentclass{beamer}
\usetheme{Darmstadt}
\usepackage{tikz}
\usetikzlibrary{shapes}

\newcommand{\Cloud}[2][180]% [angle], content
{   \begin{tikzpicture}[overlay]
        \node[align=center, draw, shading=ball, text=white, cloud callout, cloud puffs=17, cloud puff arc=140, callout pointer segments=3, anchor=pointer, callout relative pointer={(#1:2 cm )}, aspect=4,scale=0.5] at (0.2ex,0.5ex) {#2};
\end{tikzpicture}
}

\begin{document}

\begin{frame}[t]
    \begin{itemize}
        \item XY Resistive MM\Cloud{Thank you Rui}
    \item Manufactured by Rui de Oliveira\Cloud[160]{Thanks again}
    \item bla bla bla\Cloud[120]{Thanks yet another time}
    \end{itemize}
\end{frame}

\end{document}

答案2

这是另一种方法：首先标记云的起始点，然后从该位置开始定位云。该命令\mycallout具有覆盖感知功能，因此允许您进行一些自定义。

请注意，无论是否标记了点，您都可以定位云，但这样做可以使指针相对于句子垂直对齐（最后一个云不是）。

Percusse 建议对源自您的代码的警告进行注释：

  • 选项slidetop：

类 beamer 警告：slidestop'' is obsolete. Use输入行 343 上显示为 t''。

  • 选项mathserif：

类 beamer 警告：mathserif'' is obsolete. Use font theme输入行 343 上的 serif'' 带有选项“onlymath”。

您可以通过替换代码中的前两行来避免这些问题：

\documentclass[t,compress,12pt,xcolor=dvipsnames,]{beamer}
\usefonttheme[onlymath]{serif}

请注意，该snakes库也已过时：decorations尽管当前示例中不需要，您仍然可以使用它。
