Semantic label for a plane in a multi-plane image.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Luma = 0

Luma (Y) — brightness in YCbCr color spaces.

ChromaCb = 1

Chroma blue-difference (Cb / U).

ChromaCr = 2

Chroma red-difference (Cr / V).

Red = 3

Red channel.

Green = 4

Green channel.

Blue = 5

Blue channel.

Alpha = 6

Alpha (transparency) channel.

Depth = 7

Depth map.

GainMap = 8

Gain map (e.g., Ultra HDR).

Gray = 9

Grayscale (single-channel luminance, not part of YCbCr).

OklabL = 10

Oklab lightness (L).

OklabA = 11

Oklab green-red axis (a).

OklabB = 12

Oklab blue-yellow axis (b).
