iwiMulC

Syntax

typedef struct _IwiMulCParams { IppRoundMode roundMode; IppHintAlgorithm algoMode; int scaleFactor; IwiChDescriptor chDesc; } IwiMulCParams;
static IW_INLINE void iwiMulC_SetDefaultParams( IwiMulCParams *pParams )
IW_DECL(IppStatus) iwiMulC( const double *pValues, const IwiImage *pSrcImage, IwiImage *pDstImage, const IwiMulCParams *pAuxParams, const IwiTile *pTile );
Parameters
pValues
Pointer to the array containing values by which the source image is multiplied: one element for each channel.
pSrcImage
Pointer to the second image.
pDstImage
Pointer to the resulting image (can be the same as
pSrcImage
).
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.
Auxiliary Arguments
