% Beamer template as alternative for UAntwerp powerpoint template.
% Because most projectors are 16x9 these days, I chose to optimize the
% template for this situation. However, it also works fine in 4x3.
%
% Frame size (4x3): 128mm by 96mm, (16x9): 160mm by 90mm
% Original ppt template size: 254mm by 190.5mm (4x3)

\defnewlength{\pptwidth}{254mm} % slide width in ppt template
\newcommand{\absbeamerpptwidthscale}{1*\ratio{128mm}{\pptwidth}} % absolute scale factor cm in ppt
\newcommand{\beamerpptwidthscale}{1*\ratio{\beamer@paperwidth}{\pptwidth}} % relative scale factor for widths
\newcommand{\beamerpptheightscale}{1*\ratio{\beamer@paperheight}{\pptheight}} % relative scale factor for heights
\defnewlength{\pptwcm}{1cm * \beamerpptwidthscale} % 1cm width relatively scaled from ppt
\defnewlength{\ppthcm}{1cm * \beamerpptheightscale} % 1cm relatively height scaled from ppt
\defnewlength{\abspptcm}{1cm * \absbeamerpptwidthscale} % 1cm in any direction from ppt
