Export as PPTX (screenshots)

Export an HTML slide deck to a .pptx as full-bleed PNG images. Pixel-perfect, not editable. One gen_pptx tool call.

Steps

  1. show_to_user the deck.
  2. Call gen_pptx:
{
  "mode": "screenshots",
  "width": 1920, "height": 1080,
  "slides": [
    { "showJs": "goToSlide(0)", "selector": "body" },  // selector unused in screenshot mode but required
    { "showJs": "goToSlide(1)", "selector": "body" }
  ],
  "hideSelectors": [".nav", ".progress"],
  // If the deck wraps slides in a transform:scale() container, name it here so
  // the deck is forced to width × height inside the locked iframe.
  "resetTransformSelector": ".slide-container",
  "filename": "my-deck"
}

If — and only if — the user asked for Google Slides, also pass "offer_google_slides": true: the export dialog gains a 'Send to Google Slides' button, and the upload happens only if they click it.

slides[].delay defaults to 600ms — bump if transitions are slower.

If the deck uses the <deck-stage> starter component

  • resetTransformSelector: "deck-stage" — same as editable mode; the component drops its shadow-DOM transform: scale() so the slides fill the locked iframe.
  • slides[N].showJs: "document.querySelector('deck-stage').goTo(N)" — 0-indexed, so slide 1 is goTo(0).
  • hideSelectors is unnecessary — the overlay and tap-zones live in shadow DOM and aren't captured.

Validation

Same flags as editable mode. Watch for duplicate_adjacent (showJs didn't navigate) and reset_selector_miss / slide_size_mismatch (your resetTransformSelector matched nothing or didn't size to width × height).

Speaker notes from #speaker-notes are attached automatically. Page reloads after.
