Gamma Fixed 16:9 Background Resizer
Gamma slides are fluid by default but Page Setup can hold them to a fixed 16:9 ratio. Prepare a consistent full-slide visual for a Gamma deck that will export to a fixed presentation format. This preset creates a 1920×1080 JPG while preserving the 16:9 slide shape; review the crop before adding it to your deck.
