WarpQuadGetSize
Computes the size of the specification structure and the size of the temporary buffer for warping an arbitrary quadrangle in the source image to the quadrangle in the destination image.

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:
|
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. |
