Function

vDSP_vfixu8(_:_:_:_:_:)

Converts an array of single-precision floating-point values to unsigned 8-bit integer values, rounding towards zero.

Declaration

func vDSP_vfixu8(_ __A: UnsafePointer<Float>, _ __IA: vDSP_Stride, _ __C: UnsafeMutablePointer<UInt8>, _ __IC: vDSP_Stride, _ __N: vDSP_Length)

Parameters

__A

Source vector.

__IA

Source vector stride length.

__C

Destination vector.

__IC

Destination vector stride length.

__N

Number of elements in vector.

Discussion

If the resulting value is outside the bounds of the output type, the behavior is undefined. If you need to handle out-of-bounds data, you should use one of the functions in Clipping Operations on the data first.
