Colleagues: Reproduced below are key portions of recent email exchanges with Dominic Mazzoni of Google, who has implemented hit region support in Chrome. This should give us two independent hit region implementations, which we very much need for low-vision/magnification support in Canvas. Janina ------------------------------------------------------------------------------- Date: Tue, 24 Mar 2015 07:47:38 -0700 From: Dominic Mazzoni <dmazzoni@google.com> Chrome has hit region support implemented now. You can try it by visiting this url and clicking "Enable" next to "Enable experimental canvas features", and then restarting Chrome. chrome://flags/#enable-experimental-canvas-features Do you know if anyone would be interested in helping to test our implementation against the spec for compliance? I think we can probably ship it if it looks like there's broad consensus and other browsers are shipping or actively working on it. ------------------------------------------------------------------------------- Date: Tue, 24 Mar 2015 15:58:33 -0500 From: Richard Schwerdtfeger <schwer@us.ibm.com> Hi Dominic, We found some defects with canvas hit testing over a month ago in test cases: https://www.w3.org/wiki/HTML/Canvas_Task_Force/CR-Test#drawFocusIfNeeded_when_a_default_path_is_provided_and_the_associated_fallback_element_is_descendant_of_the_element_with_+focus._Scroll_the_window_so_that_the_canvas_moves See test cases 2.12 on for Chrome Canary. Were these issues fixed? -- Janina Sajka, Phone: +1.443.300.2200 sip:janina@asterisk.rednote.net Email: janina@rednote.net Linux Foundation Fellow Executive Chair, Accessibility Workgroup: http://a11y.org The World Wide Web Consortium (W3C), Web Accessibility Initiative (WAI) Chair, Protocols & Formats http://www.w3.org/wai/pf Indie UI http://www.w3.org/WAI/IndieUI/
