# Filling buffers Fill a buffer with a specified color. ## Topics ### Filling buffers [`func vImageBufferFill_CbCr8(UnsafePointer, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageBufferFill_CbCr8(_:_:_:)) Fills an 8-bit-per-channel, 2-channel interleaved buffer with a specified color. [`func vImageBufferFill_CbCr16U(UnsafePointer, UnsafePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageBufferFill_CbCr16U(_:_:_:)) Fills an unsigned 16-bit-per-channel, 2-channel interleaved buffer with a specified color.
