vImageConvert_16Fto16Q12(_:_:_:)

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

Declaration

func vImageConvert_16Fto16Q12(_ src: UnsafePointer<vImage_Buffer>, _ dest: UnsafePointer<vImage_Buffer>, _ flags: vImage_Flags) -> vImage_Error

src:
The source vImage buffer.
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 0.0 to 0 and 1.0 to 4096.
