Stream the canvas as the drawing is made about atrament HOT 4 CLOSED

Hi there @MisterDA, thanks for submitting your question! This is a very interesting proposition, I think both techniques you mention are sensible. I guess it depends on your use case. Capturing the stream would allow you to broadcast anything that happens to the canvas (not just Atrament drawing), and crucially, the timing would be much more precise. With compression I think the bandwidth also wouldn't be a huge issue.

On the other hand, sending the stroke data would let you save the state on the client's device, allowing you to replay the drawing step by step or even modifying it.

If you can share more about your project, I'd be happy to think about it a bit more :)

Does Atrament have a "real time" event watcher that would allow sending the drawing moves as they are made?

Of course, I’d like to do a simple online Pictionary :) Atrament seems the nicest sketchpad lib out there.

Amazing! Atrament does indeed support stroke recording, see the section on Programmatic Drawing in the README. Let me know if you have any further questions :)
