Slide Editor | Transitions & Animations

The Transitions and Animations tabs. Both are written the way PowerPoint writes them, round-trip untouched, and play in the editor’s own slide show.

Transitions

Kinds	None, Fade, Push, Wipe, Split, Reveal, Cover, Zoom and Morph
Options	Duration, direction (where the kind has one)
Apply to all	Copies this slide’s transition onto every slide
Advance	On click and/or after N seconds
Preview	Plays the transition on the editing surface

Written as mc:AlternateContent with the p14 duration, the form PowerPoint itself uses.

var c = editor.Controller!;

c.SetTransitionKind(SlideTransitionKind.Push);
c.SetTransition(transition, applyToAll: false);   // a SlideTransition with duration, direction, advance
c.UpdateTransition(...);
c.ApplyTransitionToAll();

Animations

Group	Effects
Entrance	Appear, Fade, Fly In, Wipe, Zoom
Emphasis	Grow/Shrink, Spin, Pulse
Exit	Disappear, Fade Out, Fly Out

Each effect has a trigger — on click, with previous, or after previous — plus a duration and a delay. The animation pane lists the slide’s sequence to reorder or remove, and numbered markers show on the slide while the Animations tab is open.

c.Animate(SlideAnimationEffect.FlyIn, add: true);   // add another, or replace the shape's effect
c.UpdateAnimation(...);                              // trigger, duration, delay
c.MoveAnimation(...); c.RemoveAnimation(...);
c.ShowAnimationMarkers = true;

Triggers are SlideAnimationTrigger.OnClick, WithPrevious and AfterPrevious. Animations are stored in p:timing (with p:bldLst) and round-tripped. Deleting a shape prunes its animations, so no timing entry is left pointing at nothing.
