You can (with a workaround) get the dimensions of a slide. Here is a simple example:
var slideImg = slide.getImageAsBase64();
await slide.context.sync();
//create an new image (that wont be loaded) based on the bas64 string and set the dimensions
const img = new Image();
img.src = "data:image/jpeg;base64, " + slideImg.value;
await img.decode();
return { width: img.width, height: img.height };
We're also using `getImageAsBase64()` in order to get the slide width/height. However, we found it does have issues since you need to convert from pixels to points which is dependant on the user's DPI. Its nice to have but we really need MS to give us the dimensions.
