I want to develop a PowerPoint Add-in that applies visual effects on the selected image in a PowerPoint slide and insert it as a separate image. Therefore, I need to get the pixel data to process it.
I tried to use getDataAsync function but when I change the CoercionType to Image, I got an error that this coercion type is not supported. I searched the Office-js documents and found nothing to get the image's pixel values.
Is there a way to do this?
