标注中的不同注释

Question

我怎样才能改变颜色和形状

\note{0,0}{Center}

在这个例子中

\documentclass[11pt]{scrartcl} % use larger type; default would be 10pt
\usepackage[wby]{callouts}
 \usepackage{mwe}% for the example image
\begin{document}

  \begin{annotate}{\includegraphics[width=\textwidth]{example-image}}{0.25}
    \helpgrid[gray]
    \note{0,0}{Center} <---------------------------------------------------------------
    \callout{40,3}{Mushrom}{3,2}
    \arrow{-3,-2.4}{-4.5,-3}
    %And raw tikz
    \draw[very thick,red] (-4,4) rectangle (-3,3);
  \end{annotate}
\end{document}

我怎样才能做这样的笔记

\node[rectangle callout, fill=myblue,text width=2cm,align=center,font=\sffamily\bfseries\color{white},#1] at #2 {#3}; 

在上面的例子中？

Answer 1

该callouts包非常简单，更改其命令以明确传递选项并不难。在此重新定义中，我将所有选项留给了用户。请注意，该包不使用 TikZshapes.callouts库，因此我添加了它，以便您可以使用您的标注形状代码。

\documentclass[11pt]{scrartcl} % use larger type; default would be 10pt
\usepackage[wby]{callouts}
\usetikzlibrary{shapes.callouts} % added
 \usepackage{mwe}% for the example image
\renewcommand{\note}[3][]{%
\node [#1] at (#2) {#3};
}

\begin{document}

  \begin{annotate}{\includegraphics[width=.7\textwidth]{example-image}}{0.25}
    \helpgrid[gray]
    \note[rectangle callout, fill=blue,text width=2cm,align=center,font=\sffamily\bfseries\color{white}]{0,0}{Center} <---------------------------------------------------------------
    \callout{40,3}{Mushrom}{3,2}
    \arrow{-3,-2.4}{-4.5,-3}
    %And raw tikz
    \draw[very thick,red] (-4,4) rectangle (-3,3);
  \end{annotate}
\end{document}
