How would an API look like? This would be impossible with `contextIsolation` (you cannot pass an `HTMLElement` around). Your first problem with cropping could be solved by passing `rect` to `capturePage`, e.g. via `getBoundingClientRect` which can be safely obtained in the renderer and serialized. What's left is that you seem to have issues with transparency not being conserved. I assume because you want to capture only a given element without things like the background color of the `body` being rendered as well? Or in the case of `getBoundingClientRect` you wouldn't want elements that overlap it (e.g. position: fixed) to also be captured? about electronjs.org-old CLOSED
