I have a need where It would make the users life a lot easier if I could provide a way to paste the image data from the clipboard and get those image bytes. I could then store them off to db or file or send them out to a REST call for OCR. I’ve been looking at the async clipboard API and have writt…

Essentially, my thought is to have a very simple page that only has a button to get the image from the clipboard and show that page in an inline frame on the perspective view. Is that not possible?
