# Permuting Channels Reorder the channels in an image. ## Topics ### Permuting channels [`func vImagePermuteChannels_RGB888(UnsafePointer, UnsafePointer, UnsafePointer!, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePermuteChannels_RGB888(_:_:_:_:)) Permutes the channels of an 8-bit-per-channel, 3-channel interleaved buffer. [`func vImagePermuteChannels_ARGB8888(UnsafePointer, UnsafePointer, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePermuteChannels_ARGB8888(_:_:_:_:)) Permutes the channels of an 8-bit-per-channel, 4-channel interleaved buffer. [`func vImagePermuteChannels_ARGB16U(UnsafePointer, UnsafePointer, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePermuteChannels_ARGB16U(_:_:_:_:)) Permutes the channels of an unsigned 16-bit-per-channel, 4-channel interleaved buffer. [`func vImagePermuteChannels_ARGB16F(UnsafePointer, UnsafePointer, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePermuteChannels_ARGB16F(_:_:_:_:)) Permutes the channels of a floating-point 16-bit-per-channel, 4-channel interleaved buffer. [`func vImagePermuteChannels_ARGBFFFF(UnsafePointer, UnsafePointer, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePermuteChannels_ARGBFFFF(_:_:_:_:)) Permutes the channels of a floating-point 32-bit-per-channel, 4-channel interleaved buffer. ### Permuting channels with masked insert [`func vImagePermuteChannelsWithMaskedInsert_ARGB8888(UnsafePointer, UnsafePointer, UnsafePointer, UInt8, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePermuteChannelsWithMaskedInsert_ARGB8888(_:_:_:_:_:_:)) Permutes and overwrites the channels of an 8-bit-per-channel, 4-channel interleaved buffer. [`func vImagePermuteChannelsWithMaskedInsert_ARGB16U(UnsafePointer, UnsafePointer, UnsafePointer, UInt8, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePermuteChannelsWithMaskedInsert_ARGB16U(_:_:_:_:_:_:)) Permutes and overwrites the channels of an unsigned 16-bit-per-channel, 4-channel interleaved buffer. [`func vImagePermuteChannelsWithMaskedInsert_ARGBFFFF(UnsafePointer, UnsafePointer, UnsafePointer, UInt8, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePermuteChannelsWithMaskedInsert_ARGBFFFF(_:_:_:_:_:_:)) Permutes and overwrites the channels of a floating-point 32-bit-per-channel, 4-channel interleaved buffer. --- Copyright © 2026 Apple Inc.
