Proposal for a Screenshot-Capturing API in Browsers

Hello all,

I’m one of the developers working for Chrome. I’m drafting a proposal for introducing an API to allow grabbing a screenshot. (This would probably cover some of the use cases html2canvas solves, but not all, as it will require manual user confirmation, which IIUC html2canvas does not require.)

How can you help?

1. You could check out my very early draft and leave some comments and/or PRs.
2. When the time comes to ship this, if consensus cannot be reached with other browser vendors (a decently likely outcome), the other option is to show overwhelming interest from web developers. If you register interest by leaving a comment either here or on my repo, that would be a good first step.

Thanks, Elad

In some situations, I think node capture API is more helpful, for example, document.body.captureAsImage() will return the image capture of body

Correct me if I am wrong, but this is a hypothetical API, and not an existing one? If so, you’re welcome to suggest it, implement it and drive standardization of it, but I am afraid you’ll find it easier said than done. But preferCurrentTab is already implemented and Chrome is a third of the way into approving shipping it. Better one bird in the hand than two on the tree, they say where I am from. 😃
