Converts an ARGB16U image to an RGB16U image.


func vImageConvert_ARGB16UtoRGB16U(_ argbSrc: UnsafePointer<vImage_Buffer>, _ rgbDest: UnsafePointer<vImage_Buffer>, _ flags: vImage_Flags) -> vImage_Error



A pointer to a vImage buffer structure that contains the ARGB interleaved source pixels.


A pointer to a vImage buffer data structure. You're responsible for filling out the height, width, and 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, you must deallocate the memory.


The options to use when performing the operation. If you plan to perform your own tiling or use multithreading, pass kvImageDoNotTile.

Return Value

kvImageNoError; otherwise, one of the error codes described in Data Types and Constants.


The conversion from ARGB16U to RGB16U is:

 rgbDest[i*3+0] = argbSrc[i*4+1];
 rgbDest[i*3+1] = argbSrc[i*4+2];
 rgbDest[i*3+2] = argbSrc[i*4+3];

This function can work in place if ( == && (argbSrc.rowBytes == rgbDest.rowBytes).
