IW_DECL(IppStatus) iwiWarpAffine_Process( const IwiWarpAffineSpec *pSpec, const IwiImage *pSrcImage, IwiImage *pDstImage, const IwiTile *pTile );
Parameters
pSpec
Pointer to the internal specification structure.
pSrcImage
Pointer to the source image.
pDstImage
Pointer to the destination image.
pTile
Pointer to the
IwiTile
structure for tiling. If
NULL
, the whole image is processed.
