How can I change the color ans shape of
\note{0,0}{Center}
in this example
\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}
How can I put such notes
\node[rectangle callout, fill=myblue,text width=2cm,align=center,font=\sffamily\bfseries\color{white},#1] at #2 {#3};
in the example above?
