Good morning/evening,

Following-up on my presentation on April 25, the Color on the Web CG
[1] would very much appreciate any feedback the MEIG might have 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 RGB color space.

Best,

-- Pierre [CG co-chair]
