Overlays can fade in from a side or darken the edges. In the Slide panel, on
a slide with a photo or video background, the overlay is now Off, Solid, Linear,
Vignette or Center. Linear is dark at one side or corner and clear at the other,
so text over a photo has a darker side to sit on. Pick from eight directions or
set any angle. Vignette keeps the middle clear and darkens the edges, and Center
darkens the middle. Each shape has its own colour and opacity, and Vignette and
Center have a size.
Off turns the overlay off. Choosing Off removes the overlay from the slide
instead of leaving a faint one behind. A slide you already made keeps its overlay
exactly as it was, and the panel shows which shape it matches.
The PDF and PowerPoint exports draw these overlays. A vignette or a fade from
the bottom comes out as a gradient, not as one averaged tint.
New slides start with no transition. Slides you add, and decks you generate or
import, begin with no transition instead of Fade. Pick one in the Slide panel
when you want it. Slides already in your decks keep the transition they have.
Apply one transition to every slide. Under Transition, Apply to all slides
gives every slide in the deck the transition you have picked, including its
duration, in one step. Undo puts every slide back at once.
