Good morning/evening:

The Color on the Web CG [1] would very much appreciate your feedback
on the following strawman, which motivates and proposes baseline
modifications to the HTML Canvas API to enable support for
High-Dynamic Range (HDR) imagery:

https://github.com/w3c/ColorWeb-CG/blob/8eac62f15e5b41940636beb031f6214b61e933af/hdr_html_canvas_element.md

The proposed modifications allow the HTML Canvas API to manipulate
High Dynamic Range (HDR) images expressed using the widespread BT.2100
PQ and BT.2100 HLG color spaces, without precluding adding future HDR
capabilities, such as support for additional color spaces like a
linear high-dynamic range color space.

Best,

-- Color on the Web CG chairs
