MulPackConj
Multiplies a source image by the complex conjugate image with data in packed format and stores the result in the destination buffer in the packed format.
Syntax
Case 1: Not-in-place operation
IppStatus ippiMulPackConj_<mod>(const Ipp32f* pSrc1, int src1Step, const Ipp32f* pSrc2, int src2Step,Ipp32f* pDst, int dstStep, IppiSize roiSize);
Supported values for mod:
| 32f_C1R |

| 32f_AC4R | 
Case 2: In-place operation
IppStatus ippiMulPackConj_<mod>(const Ipp32f* pSrc, int srcStep, Ipp32f* pSrcDst, int srcDstStep, IppiSize roiSize);

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 functionmultiplies 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. |
