Hi webkit-dev,

(and sorry for the duplicate post here, I mangled the headers on the previous post!)

This is a request for WebKit's position on display-p3 support for Canvas 2D. This is already being tracked in bugs.webkit.org here.

Summary:

Adds a color space parameter to CanvasRenderingContext2DSettings, which defaults to "srgb" and can take on the value of "display-p3". Adds ImageDataSettings, which allows specifying a color space parameter to getImageData/createImageData and related constructors.

Spec:

WhatWG spec changes merged in this PR.

Tests:

https://github.com/web-platform-tests/wpt/tree/master/html/canvas/element/wide-gamut-canvas
Includes tests of ImageData (get and put), and ensuring no loss when doing toBlob and toDataURL round-trips.

Thank you for your feedback!

Christopher
