WarpBilinearQuadGetBufferSize

Computes the size of the work buffer for bilinear warping of an arbitrary quadrangle in the source image ROI to the quadrangle in the destination image.

Syntax

IppStatus ippiWarpBilinearQuadGetBufferSize(IppiSize srcSize, IppiRect srcRoi, const double srcQuad[4][2], IppiRect dstRoi, const double dstQuad[4][2], int interpolation, int* pBufSize);

Parameters

srcSize

Size of the source image, in pixels.

srcRoi

Source image ROI (of the IppiRect type).

srcQuad

Quadrangle in the source image.

dstRoi

Destination image ROI (of the IppiRect type).

dstQuad

Quadrangle in the destination image.

interpolation

Interpolation mode. Supported values:

IPPI_INTER_NN	Nearest neighbor interpolation
IPPI_INTER_LINEAR	Linear interpolation
IPPI_INTER_CUBIC	Cubic interpolation
IPPI_INTER_EDGE	Use edge smoothing in addition to one of the above modes

pBufSize

Pointer to the size, in bytes, of the external buffer.

Description

This function computes the size of the external work buffer required for bilinear warping of an arbitrary quadrangle in the source image ROI to the quadrangle in the destination image. The result is stored in the pBufSize parameter.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when pBufSize is NULL.
ippStsSizeErr	Indicates an error: If one of the ROI coordinates has a negative value. If one of the ROI dimensions is less than, or equal to zero.
ippStsCoeffErr	Indicates an error when bilinear transformation is singular.
ippStsInterpolationErr	Indicates an error when interpolation has an illegal value.
