Parameters
pSrc1
,
pSrc2
Pointer to the ROI in the source images.
src1Step
,
src2Step
Distance in bytes between starts of consecutive lines in the source images.
pDst
Pointer to the destination image ROI.
dstStep
Distance in bytes between starts of consecutive lines in the destination image.
pSrc
Pointer to the first source image ROI for the in-place operation.
srcStep
Distance in bytes between starts of consecutive lines in the first source image for the in-place operation.
pSrcDst
Pointer to the second source and destination image ROI for the in-place operation.
srcDstStep
Distance in bytes between starts of consecutive lines in the source and destination image for the in-place operation.
roiSize
Size of the source and destination ROI in pixels.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function
multiplies pixel values
of the source image
A
by the corresponding pixel values of the complex conjugate image
A*
, represented in RCPack2D format. The result of the operation is written into the destination buffer in packed format also.
Not-in-place flavors multiply pixel values of ROI in the source images
pSrc1
and
pSrc2
, and store result in the
pDst
.
In-place flavors multiply pixel values of ROI in the source images
pSrc
and
pSrcDst
, and store result in the
pSrcDst
.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr
Indicates an error condition if any of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error condition if
roiSize
has a field with zero or negative value.
ippStsStepErr
Indicates an error condition if any of the specified buffer step values is zero or negative.

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.
