iwiMul

Syntax



    
class IwiMulParams: public ::IwiMulParams { public: IW_BASE_PARAMS_CONSTRUCTORS(IwiMulParams, iwiMul_SetDefaultParams) IwiMulParams(int _scaleFactor = 0, IppHintAlgorithm _algoMode = ippAlgHintNone, IwiChDescriptor _chDesc = iwiChDesc_None); };


    
IW_DECL_CPP(IppStatus) iwiMul( const IwiImage &src1Image, const IwiImage &src2Image, IwiImage &dstImage, const IwiMulParams &auxParams = IwiMulParams(), const IwiTile &tile = IwiTile() )
Parameters
src1Image
Reference to the first multiplied image.
src2Image
Reference to the second multiplied image.
dstImage
Reference to the resulting image (can be the same as
src2Image
).
auxParams
Reference to the auxiliary parameters structure.
tile
Reference to the
IwiTile
structure for tiling. Be default, no tiling is used.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
