Initializes the row resampling structure.

Syntax

IppStatus ippiResampleRowInit_32f(IppiResampleRowSpec_32f* pRowSpec, IppiResampleType filterType, int scrSampleWidth, int dstSampleWidth);

Parameters

srcSampleWidth	Distance between neighbor pixels of the source row on the reference grid.
dstSampleWidth	Distance between neighbor pixels of the destination row on the reference grid.
pRowSpec	Pointer to the initialized structure.
filterType	Specifies the type of the interpolation filter that is used for resampling. Possible value is ippResampleCatmullRom for the Catmull-Rom interpolation.

Description

The function ippiResampleRowInit is declared in the ippi.h file.

This function initializes in the external buffer the resampling specification structure IppiResampleRowSpec created by the user. The buffer size should be computed previously by the function ippiResampleRowGetSize. This function is necessary for the functions ippiResampleRow and ippiResampleRowReplicateBorder.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr	Indicates an error condition if one of the specified pointers is NULL.
ippStsBadArgErr	Indicates an error condition if the specified filter type is incorrect or unsupported.
ippStsOutOfRangeErr	Indicates an error condition if any of the scrSampleWidth or dstSampleWidth parameters is not valid.
