A pointer to a vImage buffer structure that contains the source image whose data you want to convert.
A pointer to a vImage buffer data structure. You're responsible for filling out the
rowfields 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
Image Do Not Tile
The conversion from 16-bit to 8-bit values is:
You can also use this function to convert a 4-channel interleaved 16U image to an ARGB8888 image by simply multiplying the width of the destination buffer by four.
