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.
An array of four 8-bit integers with the values 0, 1, 2, and 3, in some order. Each value specifies a channel from the source image that should be copied to that channel in the destination image. 0 denotes the alpha channel, 1 the red channel, 2 the green channel, and 3 the blue channel.
