Hi Pablo, I have had lots of problems with getting the correct figure dimensions for external images. In the end, I now use the code below. It is just as low-level and much more inefficient than your code, but it has not failed me yet.
\newdimen\MYfigurewidth \newdimen\MYfigureheight \unexpanded\def\MYgetfiguredimensions {\dodoubleempty\MYdogetfiguredimensions} \def\MYdogetfiguredimensions[#1][#2]% {\setbox0=\hbox{\externalfigure[#1][#2]}% \MYfigurewidth=\wd0 \MYfigureheight=\ht0 } And used like: \MYgetfiguredimensions[cow.pdf][page=1] \ifdim\MYfigurewidth>\MYfigureheight … \fi and I only use Hans’ \getfiguredimensions when I need to know a pdf page count. It is not that Hans’ macro is bad, but external figures (especially PDF, but also PNGs) can be very misbehaved. Actually forcing the inclusion into a box is crude but at least it will always return results identical to any actual desired inclusion.
