% This example shows how to use the EPSF.TEX macros.

\input epsf         % defines \epsfbox and supporting macros
\epsfverbosetrue    % messages will show height and width

\parindent=0pt
\vsize=10in
\nopagenumbers

Include the figure at its natural size:

\centerline{\epsfbox{test.epsf}}

\bigskip
Scale the figure by specifying the desired width or height;
setting both will change the aspect ratio:

\centerline{%
\epsfxsize=72pt                    % set the width
\epsfbox{test.epsf}
\hskip 1in
\epsfysize=2.0in                   % set the height
\epsfbox{test.epsf}
\hskip 1in
\epsfxsize=72pt \epsfysize=2.0in   % set both
\epsfbox{test.epsf}
}

\bigskip
Specify the bounding box explicitly if there is no ``\%\%BoundingBox'' comment
in your EPSF file:

\centerline{%
\epsfxsize=72pt                    % set the width
\epsfbox[0 0 338 338]{test.epsf}
\hskip 1in
\epsfysize=2.0in                   % set the height
\epsfbox[0 0 338 338]{test.epsf}
\hskip 1in
\epsfxsize=72pt \epsfysize=2.0in   % set both
\epsfbox[0 0 338 338]{test.epsf}
}

\vfil\eject

This figure has a bounding box with all values negative:

\centerline{\epsfbox{negbb.epsf}}

It should be ok.

\bye
