[Orbis1]

import { writeFileSync } from 'fs';
import pptxgen from 'pptxgenjs';

// 1. Create a Presentation
let pres = new pptxgen();

// 2. Add a Slide to the presentation
let slide = pres.addSlide();

// 3. Add 1+ objects (Tables, Shapes, etc.) to the Slide
slide
  .addText('Hello World from PptxGenJS...', {
    color: '363636',
    fill: { color: 'F1F1F1' },
    align: pres.AlignH.left,
    y: 1
  })
  .addImage({
    path: '/Users/UserName/Downloads/what-is-jpeg_cat.jpg',
    y: 2
  });

// 4. Save the Presentation
pres.stream().then((data) => {
  writeFileSync('example.pptx', data.toString());
});
