# vImageConvert_XRGB2101010ToARGB8888(_:_:_:_:_:_:_:) Converts an XRGB2101010 32-bit, 4-channel interleaved buffer to an 8-bit-per-channel, 4-channel interleaved buffer with permutation. ``` func vImageConvert_XRGB2101010ToARGB8888(_ src: UnsafePointer, _ alpha: Pixel_8, _ dest: UnsafePointer, _ RGB101010RangeMin: Int32, _ RGB101010RangeMax: Int32, _ permuteMap: UnsafePointer!, _ flags: vImage_Flags) -> vImage_Error ``` ## Parameters `src` A pointer to the vImage buffer that references 10-bit RGB interleaved source pixels. `alpha` The constant destination alpha value. `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. `RGB101010RangeMin` The minimum pixel value for the source image range. `RGB101010RangeMax` The maximum pixel value for the source image range. `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 The `RGB101010RangeMin` and `RGB101010RangeMax` parameters allow you to specify that the function represents source pixel values that are outside of the range `0.0 ... 1.0`. For full-range pixel values, specify `RGB101010RangeMin` and `RGB101010RangeMax` as the following: ```swift RGB101010RangeMin = 0 RGB101010RangeMax = 1023 ``` --- Copyright © 2026 Apple Inc.
