It is also possible to create powerpoints in portrait mode. Portrait mode can be very useful when you want to make a form with a lot of fields on a page or a publication with many portrait PDFs in overlay.
Follow these steps to create a portrait publication:
1. In Powerpoint, go to "design" tab and choose Slide Size > Custom Design. Set the slide size to the portrait screen of your device (for ipad Retina for instance, the optimal size is Width=26.34cm and Height=36.13cm; respect the 3:4 proportion. )
2. Create your d!nk file by selecting the appropriate landscape mode (4:3 in our example). The d!nk plugin will detect the portrait setting.
3. Check the result on in the d!nk app
