Hi Paul, I need to be able to assign a path on canvas and associate it with a dom element that has the accessibility information. My only reason for using the path to do hit testing and wire the pointer events, when the path is hit, to route the events to that same DOM object was to provide a vehicle to get the bounds of the dom element by providing a vehicle that authors to get hit testing and provide this accessibility aspect for free. Why would you not be able to create a huge rounded boarder with the path and process the events? Is that you are only interested in a hit on the transparent edges of the path? What happens to you if the mouse event results in a click within the rounded edges of the circle? ... Just trying to understand.

Mmm, Delicious! (was: hit testing and retained graphics) Sent by: public-canvas-api-request@w3.org Guys, I just wanted to be crystal clear again what our needs are - they're well defined over here: http://lists.w3.org/Archives/Public/www-svg/2011Apr/0050.html I would like to solve one problem at hand. I don't want a path. I don't want to use Canvas. I want to take a DOM element, put "pointer-events: opacity" on it and have it work. I want to be able to design a GUI with huge rounded borders and be able to click through the transparent edges at the borders. This is not just relevant to game devs. I only answered to this discussion because I thought my proposal might be relevant, when I read "hit testing" in the message title. I am *not* trying to solve the accessibility problem for our games at this time. It's definitely very desired, but not something we can tackle through tech alone, and it must be well planned.
