VectorRamp

Creates a ramp vector.

Syntax

IppStatus ippsVectorRamp_8u(Ipp8u* pDst, int len, float offset, float slope);

IppStatus ippsVectorRamp_8s(Ipp8s* pDst, int len, float offset, float slope);

IppStatus ippsVectorRamp_16u(Ipp16u* pDst, int len, float offset, float slope);

IppStatus ippsVectorRamp_16s(Ipp16s* pDst, int len, float offset, float slope);

IppStatus ippsVectorRamp_32u(Ipp32u* pDst, int len, float offset, float slope);

IppStatus ippsVectorRamp_32s(Ipp32s* pDst, int len, float offset, float slope);

IppStatus ippsVectorRamp_32f(Ipp32f* pDst, int len, float offset, float slope);

IppStatus ippsVectorRamp_64f(Ipp64f* pDst, int len, float offset, float slope);

Parameters

pDst	Pointer to the destination vector.
len	Number of elements in the vector.
offset	Offset value.
slope	Slope coefficient.

Description

The function ippsVectorRamp is declared in the ipps.h file. This function creates a ramp vector and stores the result in pDst. The destination vector elements are computed according to the following formula:

pDst[n] = offset + slope*n, 0 ≤ n < len.

Note that this function is similar to the function ippsVectorSlope, but the linear transform coefficients offset and slope have floating-point values for all flavors of the function ippsVectorRamp. In most cases the use of the function ippsVectorSlope is more preferrable.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when the pDst pointer is NULL.
ippStsSizeErr	Indicates an error when len is less than or equal to 0.
