Parameters

pSrc1Image

Pointer to the first multiplied image.

pSrc2Image

Pointer to the second multiplied image.

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.
