ResampleRowGetSize

Computes the sizes of the resample structure and the work buffer.

Syntax

IppStatus ippiResampleRowGetSize_32f(int srcSampleWidth, int dstSampleWidth, int* pSpecSize, int* pBufSize);

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.
pSpecSize	Pointer to the computed size of the structure.
pBufSize	Pointer to the computed size of the buffer.

Description

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

This function calculates sizes of the resampling parameters structure IppiResampleRowSpec structure and the work buffer utilized by the functions ippiResampleRow and ippiResampleRowReplicateBorder. These values are stored in the pSpecSize and pBufSize respectively. Calculations are performed in accordance with the parameters of resampling: widths of source and destination samples. The structure and the buffer must be created by the user. Use the function ippiResampleRowInit to initialize the IppiResampleRowSpec structure.

This function computes the sizes of the row resampling structure IppiResampleRowSpec and of the work buffer.

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.
ippStsOutOfRangeErr	Indicates an error condition if any of the scrSampleWidth or dstSampleWidth parameters is not valid.
