PPT export

buildPptFile creates a PowerPoint 97-2003 .ppt from a framework-neutral WDeck model: text, shapes, pictures, notes, embedded objects and optional RC4 encryption.

import { buildPptFile } from '@christophervr/ole2/legacy-ppt-writer';

const pptBytes = await buildPptFile({
  widthEmu: 9144000,
  heightEmu: 5143500,
  slides: [{ shapes: [] }],
  pictures: [],
});
// Save pptBytes as a .ppt file. Pass { password: '...' } as a second argument
// only when legacy RC4 output is required.

Converting a PowerPoint viewer document into WDeck is the job of pptx-viewer-core, which consumes this shared binary implementation. Creating a new deck is separate from editing an existing one with parsePpt.

Masters

WDeck.masters writes one MainMaster per entry and WSlide.masterIndex points each slide at its own. A deck without masters writes one master from masterStyles and master.

Pictures

BLIPs are png, jpg, emf, wmf and dib, matching PowerPoint's own 97-2003 save. Convert other sources first.

Constraints

Writer constraints (picture formats, media, encryption scheme, modern-only content, multi-master verification) are listed under Limitations.
