Computes magnitude of elements of a complex data image.
IppStatus ippiMagnitude_<mod>(const Ipp<srcDatatype>* pSrc, int srcStep, Ipp<dstDatatype>* pDst, int dstStep, IppiSize roiSize);
Supported values for mod:
32fc32f_C1R |
32fc32f_C3R |
IppStatus ippiMagnitude_<mod>(const Ipp<srcDatatype>* pSrc, int srcStep, Ipp<dstDatatype>* pDst, int dstStep, IppiSize roiSize, int scaleFactor);
Supported values for mod:
16uc16u_C1RSfs |
16uc16u_C3RSfs |
16sc16s_C1RSfs |
16sc16s_C3RSfs |

pSrc |
Pointer to the source image ROI. |
srcStep |
Distance in bytes between starts of consecutive lines in the source image. |
pDst |
Pointer to the destination image ROI. |
dstStep |
Distance in bytes between starts of consecutive lines in the destination image. |
roiSize |
Size of the source and destination ROI in pixels. |
scaleFactor |
Scale factor (see Integer Result Scaling). |
The function ippiMagnitude is declared in the ippi.h file. It operates with ROI (see Regions of Interest in Intel IPP).
This function computes magnitude of elements of the source image pSrc given in complex data format, and stores results in the destination image pDst.
ippStsNoErr |
Indicates no error. Any other value indicates an error or a warning. |
ippStsNullPtrErr |
Indicates an error condition if pSrc or pDst pointer is NULL. |
ippStsStepErr |
Indicates an error condition if srcStep or dstStep value is zero or negative. |
ippStsSizeErr |
Indicates an error condition if width or height of images is less than or equal to zero. |
