# vImageConvert_444AYpCbCr16ToARGB8888(_:_:_:_:_:) Converts an 16-bit-per-channel 4:4:4 YpCbCr buffer to an 8-bit-per-channel, 4-channel ARGB buffer. ``` func vImageConvert_444AYpCbCr16ToARGB8888(_ src: UnsafePointer, _ dest: UnsafePointer, _ info: UnsafePointer, _ permuteMap: UnsafePointer!, _ flags: vImage_Flags) -> vImage_Error ``` ## Parameters `src` The source vImage buffer. `dest` A pointer to the destination vImage buffer structure. You’re responsible for filling out the [`height`](/documentation/Accelerate/vImage_Buffer/height), [`width`](/documentation/Accelerate/vImage_Buffer/width), and [`rowBytes`](/documentation/Accelerate/vImage_Buffer/rowBytes) fields of this structure, and for allocating a data buffer of the appropriate size. On return, the data buffer this structure points to contains the destination image data. When you no longer need the data buffer, deallocate the memory to prevent memory leaks. `info` A [`vImage_YpCbCrToARGB`](/documentation/Accelerate/vImage_YpCbCrToARGB) structure that describes the conversion matrix, the range of the input and output pixels from the matrix, and clamping information. `permuteMap` An array of four 8-bit integers with the values `0`, `1`, `2`, and 3, in some order. Each value specifies the channel from the source image that the function copies to the destination channel at the corresponding index. `flags` The options to use when performing the operation. If your code implements its own tiling or its own multithreading, pass [`kvImageDoNotTile`](/documentation/Accelerate/kvImageDoNotTile); otherwise, pass [`kvImageNoFlags`](/documentation/Accelerate/kvImageNoFlags). ## Return Value [`kvImageNoError`](/documentation/Accelerate/kvImageNoError); otherwise, one of the error codes in . ## Discussion --- Copyright © 2026 Apple Inc.
