Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib

Parameters

interpolation

Interpolation algorithm, possible values are:

ippNearest	Nearest neighbor interpolation.
ippCubic	Cubic interpolation.
ippLinear	Linear interpolation.

dataType

Data type of the image. Possible values are ipp8u, ipp16u, ipp16s, or ipp32f.

channels

Number of channels in the image. Possible values are: ippC1, ippC3, ippC4, or ippAC4.

roiSize

Size, in pixels, of the destination ROI.

nLevels

Number of levels, separate for each channel.

pSpecSize

Pointer to the computed size, in bytes, of the specification structure.

Description

This function computes the size of the specification structure for the ippiLUT function. The result is stored in the pSpecSize parameter.

For an example on how to use this function, refer to the example provided with the ippiLUT function description.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when any of the specified pointers is NULL.
ippStsSizeErr	Indicates an error when roiSize has a field with a value less than 1.
ippStsChannelErr	Indicates an error when channel has an illegal value.
ippStsDataTypeErr	Indicates an error when dataType has an illegal value.
ippStsInterpolationErr	Indicates an error when interpolation has an illegal value.
