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 }%
