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);

Include Files

Domain Dependencies

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

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

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.
