The current Canvas 2D API was originally proposed in 2013. Since then, a lot of 2D graphics APIs have appeared and changed what developers expect from a good 2D API. This proposal tries to modernize Canvas 2D API, considering current and future usage of Canvas and considering the following:
Canvas is the web’s direct mode rendering solution that closely matches traditional programming models. This is a particularly common need for games and full featured apps.
Modern 2D developers sometimes have to fallback to GL for features that are expected to be available in 2D but currently aren’t supported by Canvas 2D.
Modern browsers implement a rich set of rendering features that are currently unavailable to developers. Bridging that gap and giving more power to developers is a good thing.
I’ve started a tentative repository, where I’m collecting explainers of some ideas we have on how to move Canvas2D forward. I’m slowly adding more features, but it would be great to get feedback and eventually move this as a full WICG repository.
