Parameters
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.
dstRoiSize
Size of the destination ROI in pixels.
pBuffer
Pointer to the work buffer. To compute the size of the buffer, use the
ippiMagnitudePackGetBufferSize
function.
Description
The API of this function has been modified in Intel IPP 9.0 release.
This function operates with ROI (see Regions of Interest in Intel IPP).
This function computes magnitude of elements of the source image
pSrc
given in RCPack2D format and stores results in the destination image
pDst
.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr
Indicates an error when
pSrc
or
pDst
pointer is
NULL
.
ippStsStepErr
Indicates an error when
srcStep
or
dstStep
value is zero or negative.
ippStsSizeErr
Indicates an error when width or height of images is less than, or equal to zero.

Product and Performance Information

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.
