WarpGetBufferSize

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

Syntax

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

Include Files

ippi.h

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.
