Function

vImageConvert_PlanarFtoPlanar16F(_:_:_:)

Converts a PlanarF image to a Planar16F image.

Declaration

func vImageConvert_PlanarFtoPlanar16F(_ src: UnsafePointer<vImage_Buffer>, _ dest: UnsafePointer<vImage_Buffer>, _ flags: vImage_Flags) -> vImage_Error

Parameters

src

A pointer to a vImage buffer structure that contains the source image whose data you want to convert.

dest

A pointer to a vImage buffer data 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, you must deallocate the memory.

flags

The options to use when performing the operation. If you plan to perform your own tiling or use multithreading, pass kvImageDoNotTile.

Return Value

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

Discussion

Planar16F pixels are 16-bit floating-point numbers, conforming to the OpenEXR standard. Denormals, NaNs, positive infinity, and negative infinity are supported. In conformance with IEEE-754, all signaling NaNs are quieted during the conversion—OpenEXR-1.2.1 does not do this.
