A pointer to a vImage buffer structure that contains the source image (for which each pixel value is a 16-bit signed integer) whose data you want to overwrite.
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 offset value to add to each pixel.
The value to multiply each pixel by.
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 function changes each pixel value to a floating-point value, scales each value and then adds the offset value. The calculation is
v are inverse transformations when you use the same offset and scale values for each. (The inversion is not precise due to round-off error.) This requires the two functions to use these values differently (and in a different order).
