Function

vImageOverwriteChannelsWithScalar_PlanarF(_:_:_:)

Overwrites a PlanarF image buffer with the provided value.

Declaration

func vImageOverwriteChannelsWithScalar_PlanarF(_ scalar: Pixel_F, _ dest: UnsafePointer<vImage_Buffer>, _ flags: vImage_Flags) -> vImage_Error

Parameters

scalar

A floating-point pixel value.

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.
