Parameters
srcSize
Size of the source image, in pixels.
srcQuad
Quadrangle in the source image.
dstSize
Size of the destination image, in pixels.
dstQuad
Quadrangle in the destination image.
transform
Type of the warp tranform. Supported values:
ippWarpAffine
Affine warping
ippWarpPerspective
Perspective warping
dataType
Data type of the source and destination images. Supported values:
ipp8u
,
ipp16u
,
ipp16s
, and
ipp32f
.
interpolation
Interpolation method. Supported values:
ippNearest
,
ippLinear
, and
ippCubic
.
borderType
Type of border. Supported values:
ippBorderTransp
Outer pixels are not processed.
ippBorderInMem
Border is obtained from the source image pixels in memory.
pSpecSize
Pointer to the size, in bytes, of the specification structure.
pInitBufSize
Pointer to the size, in bytes, of the temporary buffer.
Description
This function computes the size of the specification structure and the temporary buffer for the following functions, depending on the
interpolation
parameter:
ippiWarpQuadNearestInit
,
ippiWarpQuadLinearInit
, or
ippiWarpQuadCubicInit
.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when one of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error in the following cases:
  • If the width or height of the source or destination image is less than, or equal to one.
  • If one of the calculated sizes exceeds the maximum positive 32-bit signed integer value. The size of the one of the processed images is too large.
ippStsDataTypeErr
Indicates an error when
dataType
has an illegal value.
ippStsWarpTransformErr
Indicates an error when
transform
has an illegal value.
ippStsInterpolationErr
Indicates an error when
interpolation
has an illegal value.
ippStsQuadErr
Indicates an error when any of the given quadrangles is non-convex or degenerates into a triangle, line, or point.
ippStsWrongIntersectQuad
Indicates a warning that no operation is performed if the transformed source image extended with borders has no intersection with the destination image.
ippStsAffineQuadChanged
Indicates a warning when coordinates of the fourth vertex of
dstQuad
are changed by the function, if
transform
is set to
ippWarpAffine
.
ippStsBorderErr
Indicates an error when
borderType
has an illegal value.
