Micro-graphics in caption environment

Question

I am using my own icons in a document using

\newcommand{\icon}{\includegraphics[scale=0.2]{myicon.pdf}}

as described in this post.

Now I am trying to use this newcommand in a caption environment, but I get errors

! Argument of \@caption has an extra }.
! Paragraph ended before \@caption was complete.

Is there any way to add figures to the caption environment? or any suggested workaround to this?

Minimal example

\documentclass{article}
\usepackage{graphicx}
\newcommand{\icon}{\includegraphics[scale=0.2]{myicon.pdf}}

\begin{document}

This is an inline \icon % this part compiles good

\begin{figure}
\includegraphics[width=\linewidth]{myfigure}
\caption{This is an \icon in a caption environment.} % this part gives errors
\end{figure}

\end{document}

Could you post a small complete code reproducing the problem? — Bernard, Apr 30 '20 at 10:52
@StevenB.Segletes you probably have a newer graphics package — David Carlisle, Apr 30 '20 at 10:57

In recent releases \includegraphics is robust so should not prematurely expand when writing the .toc file, but in any release you could define your command via

\DeclareRobustCommand{\myicon}{\includegraphics[scale=0.2]{myicon.pdf}}

then it will not expand in moving environments.

Unrelated you may prefer to use something like height=1.1ex rather than scale=0.2 then the icon will adjust to font size commands such as \large.

This works just perfect, thank you! I had no idea about \DeclareRobustCommand. – rsaavedra Apr 30 '20 at 11:06

Just hope nobody downvotes you...that will really screw up your numerological aspirations. But I won't upvote, so as to keep you in reach of your goal. – Steven B. Segletes Apr 30 '20 at 11:15

@Sebastiano Maybe 5 of us could downvote to counteract! – Steven B. Segletes Apr 30 '20 at 11:16
@StevenB.Segletes I can't. Just my last downwote it is since 2018. :-) and I would hold my average :-) – Sebastiano Apr 30 '20 at 11:17

@Sebastiano Fear not. David is resourceful. He can always stack the deck and delete one of his lesser answers to reset the count. – Steven B. Segletes Apr 30 '20 at 11:18
