WarpGetBufferSize

Computes the size of the work buffer for the warp transform.

Syntax

IppStatus ippiWarpGetBufferSize(const IppiWarpSpec* pSpec, IppiSize dstRoiSize, int* pBufSize);

Flavors with the _L suffix: ippi_l.h

Domain Dependencies

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

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

Parameters

pSpec	Pointer to the specification structure for the warp operation.
dstRoiSize	Size of the processed destination image ROI, in pixels.
pBufSize	Pointer to the size of the external buffer, in bytes.

Description

This function computes the size of the external buffer for the warp transform. The specification structure pointed by pSpec defines the warp algorithm parameters.

Before using this function, you need to initialize the specification structure using one of the following functions: WarpAffineNearestInit, WarpAffineLinearInit, or WarpAffineCubicInit.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsContextMatchErr	Indicates an error when the specification structure is invalid.
ippStsSizeErr	Indicates an error in the following cases: If width or height of the destination image is negative, or equal to zero. If the calculated buffer size exceeds the maximum positive pBufSize data type. The size of the processed image ROI is too large.
ippStsSizeWrn	Indicates a warning when the size of the destination image is more than the size of the destination image origin.
