What unit is width and height from presLayout?

[AndreasNasman]

Hi!

I'm wondering what units width and height are defined in under presLayout? The super large numbers don't seem to be inches or pixels. The type definitions don't give any clues either.

In the example picture below, defineLayout is set to

const pixelWidth = 1170;
const pixelHeight = 658;
const ppi = 96;

const height = pixelHeight / ppi; // inches
const width = pixelWdith / ppi; // inches
presentation.defineLayout({
  height,
  width,
})

Found the answer by checking the source. The unit is EMU (English Metric Units) and you can convert it to inches by dividing by 914400.

const EMU = 914400;
const inchWidth = presentation.presLayout.width / EMU;
console.log(inchWidth); // 10 (the default layout width in inches: https://gitbrent.github.io/PptxGenJS/docs/usage-pres-options/#standard-slide-layouts)
