Function

vImageConvert_BGRXFFFFToPlanarF(_:_:_:_:_:)

Separates a BGRXFFFF image into three planar buffers for red, green, and blue, discarding the fourth channel.

Declaration

func vImageConvert_BGRXFFFFToPlanarF(_ src: UnsafePointer<vImage_Buffer>, _ blue: UnsafePointer<vImage_Buffer>, _ green: UnsafePointer<vImage_Buffer>, _ red: 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 separate.

blue

A pointer to a vImage buffer data structure that represents the blue channel destination. 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. When you no longer need the data buffer, you must deallocate the memory.

green

A pointer to a vImage buffer data structure that represents the green channel destination. 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. When you no longer need the data buffer, you must deallocate the memory.

red

A pointer to a vImage buffer data structure that represents the red channel destination. 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. 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.
