iwiDivC

Syntax

typedef struct _IwiDivCParams { IppRoundMode roundMode; IppHintAlgorithm algoMode; int scaleFactor; IwiChDescriptor chDesc; } IwiDivCParams;
static IW_INLINE void iwiDivC_SetDefaultParams( IwiDivCParams *pParams )
IW_DECL(IppStatus) iwiDivC( const double *pValues, const IwiImage *pSrcImage, IwiImage *pDstImage, const IwiDivCParams *pAuxParams, const IwiTile *pTile );
Parameters
pValues
Pointer to the array containing values by which the source image is divided: one element for one channel.
pSrcImage
Pointer to the image to be divided.
pDstImage
Pointer to the resulting image (can be the same as
pSrc2Image
).
pAuxParams
Pointer to the auxiliary parameters structure. If
NULL
, default parameters are used.
pTile
Pointer to the
IwiTile
structure for tiling. If
NULL
, the whole image is processed.
