I have about 1100 PowerPoint Presentations that I need to change the design from screen presentation 4:3 to screen presentation 16:9. I have been unable to find an enumeration of the variable that does this. I really don't want to do the presentations one at a time manually. Does anyone know the variable and enumeration that would allow me to programmatically change the Design > Page Setup setting in a presentation? Alternatively, a suggestion of a better way would be appreciated.
I would also appreciate suggestions on doing this in Apache OpenOffice or LibreOffice.
