vImageConvert_16Q12toF(_:_:_:)

Converts a fixed-point 16-bit planar buffer to a floating-point 32-bit planar buffer.

Declaration

func vImageConvert_16Q12toF(_ src: UnsafePointer<vImage_Buffer>, _ dest: UnsafePointer<vImage_Buffer>, _ flags: vImage_Flags) -> vImage_Error

src:
A pointer to a vImage buffer structure that contains the source image whose data you want to convert.
dest:
A pointer to the destination vImage buffer 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, deallocate the memory to prevent memory leaks.
flags:
The options to use when performing the operation. If your code implements its own tiling or its own multithreading, pass Kvimagedonottile; otherwise, pass Kvimagenoflags.

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

The conversion maps source pixels with a value of 0 to 0.0 and 4096 to 1.0.
