# ColorSyncProfileCreateDisplayTransferTablesFromVCGT(_:_:) Creates display transfer tables from the profile’s `vcgt` tag. ``` func ColorSyncProfileCreateDisplayTransferTablesFromVCGT(_ profile: ColorSyncProfile!, _ nSamplesPerChannel: UnsafeMutablePointer!) -> Unmanaged? ``` ## Discussion Creates three tables of floats (a red table, a green table, and a blue table), each of size `nSamplesPerChannel`, packed into contiguous memory contained in the returned `CFDataRef`, from the `vcgt` tag of the profile (if a `vcgt` tag exists in the profile). `CGSetDisplayTransferByTable` uses these tables. --- Copyright © 2026 Apple Inc.
