A pointer to a vImage buffer structure that contains the source image.
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
