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 aspSrcImage).
- pAuxParams
- Pointer to the auxiliary parameters structure. IfNULL, default parameters are used.
- pTile
- Pointer to theIwiTilestructure for tiling. IfNULL, the whole image is processed.
