Intel® Integrated Performance Primitives 2017 Update 3 Developer Reference
Computes the size of the specification structure and the size of the external work buffer for the warp affine transform.
IppStatus ippiWarpAffineGetSize(IppiSize srcSize, IppiSize dstSize, IppDataType dataType, const double coeffs[2][3], IppiInterpolationType interpolation, IppiWarpDirection direction, IppiBorderType borderType, int* pSpecSize, int* pInitBufSize);

Headers: ippcore.h, ippvm.h, ipps.h
Libraries: ippcore.lib, ippvm.lib, ipps.lib
srcSize |
Size of the source image, in pixels. | ||||||||
dstSize |
Size of the destination image, in pixels. | ||||||||
dataType |
Data type of the source and destination images. Supported values: ipp8u, ipp16u, ipp16s, ipp32f, and ipp64f. | ||||||||
coeffs |
Coefficients for the affine transform. | ||||||||
interpolation |
Interpolation method. Supported values: ippNearest, ippLinear, andippCubic. | ||||||||
direction |
Transformation direction. Supported values:
|
||||||||
borderType |
Type of border. Possible values are:
Mixed borders are also supported. They can be obtained by the bitwise operation OR between ippBorderTransp and the ippBorderInMemTop, ippBorderInMemBottom, ippBorderInMemLeft, ippBorderInMemRight values. |
||||||||
pSpecSize |
Pointer to the size, in bytes, of the specification structure. | ||||||||
pInitBufSize |
Pointer to the size, in bytes, of the temporary buffer. |
This function computes the size of the specification structure and the external work buffer for the following functions, depending on the interpolation parameter: WarpAffineNearestInit, WarpAffineLinearInit, or WarpAffineCubicInit.
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. |
ippStsWarpDirectionErr |
Indicates an error when direction has an illegal value. |
ippStsInterpolationErr |
Indicates an error when interpolation has an illegal value. |
ippStsCoeffErr |
Indicates an error when affine transformation is singular. |
ippStsBorderErr |
Indicates an error when borderType has an illegal value. |
ippStsWrongIntersectQuad |
Indicates a warning that no operation is performed if the transformed source image extended with borders has no intersection with the destination image. |
