Function

vImageConvert_RGB16UtoPlanar16U(_:_:_:_:_:)

Separates an RGB16U image into three Planar16U images.

Declaration

func vImageConvert_RGB16UtoPlanar16U(_ rgbSrc: UnsafePointer<vImage_Buffer>, _ rDest: UnsafePointer<vImage_Buffer>, _ gDest: UnsafePointer<vImage_Buffer>, _ bDest: UnsafePointer<vImage_Buffer>, _ flags: vImage_Flags) -> vImage_Error

Parameters

rgbSrc

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

rDest

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.

gDest

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.

bDest

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.

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

The source and destination buffers must have the same height and width.

This function doesn't work in place.
