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. |
ippStsNoOperation |
Indicates a warning if width or height of any image is zero. |
ippStsSizeErr |
Indicates an error If the width or height of the source or destination image is less than, or equal to one. |
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. |
ippStsNotSupportedModeErr |
Indicates an error if the requested mode is not supported. |
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. |
ippStsExceededSizeErr |
Indicates an error in the following cases:
