CplxExtendToPack

Converts a complex data image to an image in packed format.

Syntax

IppStatus ippiCplxExtendToPack_<mod>(const Ipp<srcDatatype>*

, int
srcStep
, IppiSize

Parameters
pSrc
Pointer to the source image ROI.
srcSize
Size in pixels of the source image ROI.
srcStep
Distance in bytes between starts of consecutive lines in the source buffer.
pDst
Pointer to the destination image buffer.
dstStep
Distance in bytes between starts of consecutive lines in the destination image buffer.
Description
This function operates with ROI (see Regions of Interest in Intel IPP ).
This function converts the source image
pSrc
in complex data format to RCPack2D format and stores the results in
pDst
, which is a real array of dimensions (
N
x
M
). The
pSrc
is a matrix with complete set of the Fourier coefficients.
Return Values
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
srcSize
has field with zero or negative value.

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. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
