Declaration
func adding(headroomAdaptiveGainCurveMetadata: Data, options: ColorSyncProfile.HeadroomAdaptiveGainCurveOptions = .init()) -> ColorSyncProfile?Parameters
- headroomAdaptiveGainCurveMetadata:
The raw HAGC payload to embed.
- options:
Options that configure embedding. Reserved for future use.

Return Value
A new profile carrying the HAGC tag, or nil if this profile’s transfer function isn’t PQ, HLG, or linear, or if embedding fails.
Discussion
Use this to move an HAGC between profiles without interpreting it — for example, to carry the HAGC payload read from one profile into another, or one shared with a video stream (SMPTE ST 2094-50 payload). The original profile is unchanged.
