We had discussions about a new property for CanvasContext .filter(). Which takes a CSS filter string. Every drawing step would be filtered individually. Just like shadow.

Another idea was to have a property that takes and ImageData as input, filters it and returns an ImageData object.

I think the first idea is more powerful and better implementable in HW.

I am not sure if any of these ideas should go to Filter Effects or to Canvas directly referencing Filter Effects.

Greetings,
Dirk
