From one of my private modules:

    \useexternalfigure[cnp:name][\cut!n!paste!parameter\c!name]% Is this really needed?
    \getfiguredimensions[cnp:name]%
    \edef\cut!n!paste!NOfpages    {\noffigurepages}%
    % MkII returns dimensions in pt, MkIV returns in sp
    % which causes metapost to blow up. So, I use \dimexpr to convert
    % sp to pt.
    \edef\cut!n!paste!figurewidth {\the\dimexpr\figurenaturalwidth   }%
    \edef\cut!n!paste!figureheight{\the\dimexpr\figurenaturalheight  }%
