Expand description

The video transfer function defines the formula for converting between non-linear RGB (R’G’B’) and linear RGB

Variants (Non-exhaustive)§

This enum is marked as 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.
