# Functions that deinterleave noninteger interleaved buffers Separate fixed- and floating-point interleaved buffers into discrete planar buffers. ## Topics ### Deinterleaving 32-bit interleaved buffers [`func vImageConvert_ChunkyToPlanarF(UnsafeMutablePointer, UnsafeMutablePointer?>, UInt32, Int, vImagePixelCount, vImagePixelCount, Int, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_ChunkyToPlanarF(_:_:_:_:_:_:_:_:)) Deinterleaves a floating-point 32-bit-per-channel interleaved buffer with an arbitrary number of channels into the corresponding number of 32-bit planar buffers. ### Deinterleaving 32-bit three-channel interleaved buffers [`func vImageConvert_RGBFFFtoPlanarF(UnsafePointer, UnsafePointer, UnsafePointer, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_RGBFFFtoPlanarF(_:_:_:_:_:)) Deinterleaves a floating-point 32-bit-per-channel, 3-channel interleaved buffer into three floating-point 32-bit planar buffers. ### Deinterleaving 32-bit four-channel interleaved buffers [`func vImageConvert_ARGBFFFFtoPlanar8(UnsafePointer!, UnsafePointer!, UnsafePointer!, UnsafePointer!, UnsafePointer!, UnsafePointer!, UnsafePointer!, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_ARGBFFFFtoPlanar8(_:_:_:_:_:_:_:_:)) Deinterleaves a floating-point 32-bit-per-channel, 4-channel interleaved buffer into four 8-bit planar buffers. [`func vImageConvert_BGRXFFFFToPlanarF(UnsafePointer, UnsafePointer, UnsafePointer, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_BGRXFFFFToPlanarF(_:_:_:_:_:)) Deinterleaves a floating-point 32-bit-per-channel, 4-channel interleaved buffer into three floating-point 32-bit planar buffers and discards the last channel. [`func vImageConvert_XRGBFFFFToPlanarF(UnsafePointer, UnsafePointer, UnsafePointer, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_XRGBFFFFToPlanarF(_:_:_:_:_:)) Deinterleaves a floating-point 32-bit-per-channel, 4-channel interleaved buffer into three floating-point 32-bit planar buffers and discards the first channel. [`func vImageConvert_ARGBFFFFtoPlanarF(UnsafePointer, UnsafePointer, UnsafePointer, UnsafePointer, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_ARGBFFFFtoPlanarF(_:_:_:_:_:_:)) Deinterleaves a floating-point 32-bit-per-channel, 4-channel interleaved buffer into four floating-point 38-bit planar buffers. --- Copyright © 2026 Apple Inc.
