Graphics, Figures & Tables ⇒ How to change the frame line thickness ?

[Cham]

I don't need anything fancy. Just to change the frame thickness in this MWE example :

Code: Select all

\documentclass[12pt,letterpaper,twoside]{book}
\usepackage{lmodern}
\usepackage{amsmath}
\usepackage{graphicx}

\begin{document}

	\begin{figure}
		\centering
		\frame{\includegraphics[height=6.5cm]{example-image}}
	\end{figure}

\end{document}

If possible, I don't want to use another package just to change the line thickness. Any suggestion ? Are there some options for the \frame command ?

Better use fbox.

Code: Select all

\documentclass[12pt,letterpaper,twoside]{book}
\usepackage{lmodern}
\usepackage{amsmath}
\usepackage{graphicx}

\begin{document}

\begin{figure}
\centering
\setlength{\fboxrule}{5pt}
\setlength{\fboxsep}{0pt}
\fbox{\includegraphics[height=6.5cm]{example-image}}
\end{figure}
\begin{figure}
\centering
\makeatletter
\@wholewidth5pt
\makeatother
\frame{\includegraphics[height=6.5cm]{example-image}}
\end{figure}

\end{document}

Indeed, fbox appears to solve my issue. Thanks a lot !
