Hi all,

I need a macro that includes a graph but automatically adds a
'width=\textwidth' parameter if the included graph is wider than
\textwidth. Any ideas? Thanks.

Dunno why graphicx doesn't have a maximum width function. workaround
is here

Thank you for this. By the way the macro:

\newlength{\testwd}
\newcommand{\fitpic}[1]{%
  \settowidth{\testwd}{\includegraphics{#1}}%
  % \message{#1 width=\the\testwd, page=\the\textwidth}%
  \ifthenelse{\lengthtest{\testwd>\textwidth}}{%
    \noindent\includegraphics[width=\textwidth]{#1}}{%
    \centering\includegraphics{#1}}}

seems to use includegraphics twice. Is that expensive (slow)?

Thanks again.

\newcommand*{\maxwidth}{%  
  \ifdim\Gin@nat@width<\linewidth
    \linewidth
  \else
    \Gin@nat@width
  \fi
}
\makeatother

\includegraphics[width=\maxwidth]{...}

potentially, yes.  the next entry in the thread, from heiko oberdiek,
is the one i use (when i'm doing figures, which isn't often):

\documentclass{article}
\usepackage{graphicx}
\makeatletter
\def\maxwidth{\ifdim\Gin@nat@width>\linewidth\linewidth
\else\Gin@nat@width\fi}
\makeatother
\begin{document}
\noindent
\includegraphics[width=\maxwidth]{picture.png}
\end{document}

i _think_ i had worked it out independently, actually.  (let's claim i
did: heiko doesn't need any more glory, and i'm a mere drudge... ;-)

As far as I can remember, it isn't my invention, but I cannot remember
the exact source.
