# Append .eps to included figures [duplicate]

Is there a way to define a new command so that existing

\includegraphics[scale=x]{fig_name}


becomes

\includegraphics[scale=x]{fig_name.eps}


for any x and fig_name? This is for automatic conversion of eps to pdf because eps may cause out of memeory issues with xdvipdfmx: xdvipdfmx out of memory.

If all your usages exclude the use of a file extension, then you can simply do

\usepackage{graphicx,letltxmacro}
\LetLtxMacro{\oldincludegraphics}{\includegraphics}
\renewcommand{\includegraphics}[2][]{\oldincludegraphics[#1]{#2.eps}}


which would transform

\includegraphics[*]{**}


to

\includegraphics[*]{**.eps}


The use of letltxmacro is required in order to cope with the optional argument of \includegraphics. See When to use \LetLtxMacro?

Alternatively, and perhaps much easier, you can use

\DeclareGraphicsExtensions{.eps}
