# Change: Add PPT slide transitions
|
|
|
|
## Why
|
|
|
|
PPT pages currently play and export as immediate cuts. Users need per-page transition choices that feel close to PowerPoint, apply during in-app playback, and survive PPTX download.
|
|
|
|
## What Changes
|
|
|
|
- Add per-PPT-page transition metadata to Frame PPT data.
|
|
- Add an animation/transition submenu to the single-page PPT right-click menu with hover-revealed transition choices.
|
|
- Apply the selected page transition during `FrameSlideshow` playback.
|
|
- Export selected transitions into downloaded PPTX files by post-processing generated OOXML, because `pptxgenjs` does not expose a slide transition API.
|
|
- Keep scope to slide/page transitions; element-level entrance/emphasis animations are out of scope for the current image-first PPT model.
|
|
