PDF Embed API - get Screenshot?

[cvan15A7]

How do I take a screenshot of an area in a PDF file when I have coordinates for that place?
This is exactly about the screenshot of annotation.

Hi, Thanks for choosing PDF Embed API, Currently it is not possible to achieve the requested behavior. Please stay tuned for more updates.

Embed API does not prevent OS level screen captures. Are you asking how to render a portion of a page to an image?

"Are you asking how to render a portion of a page to an image? "

Yes. But I want to be able to do it from the frontend, from client side.
I'd rather not do that from the backend.

I would like to use `result [0] .target.selector.boundingBox`, plus margin.

Ok - That's quite complicated even with basic HTML that's not inside a canvas. Take a look at the top answer on Stack here. You might be able to use the html2canvas script but I have not tried it personally.

html2canvas doesn't work at all for iframe.

As if to have access to the contents of an iframe, it would be possible.
