PackToCplxExtend

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

Syntax

IppStatus ippiPackToCplxExtend_32f32fc_C1R(const Ipp32f* pSrc, IppiSize srcSize, int srcStep, Ipp32fc* pDst, int dstStep);

Libraries: ippcore.lib, ippvm.lib, ipps.lib

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 RCPack2D format to complex data format and stores the results in pDst, which is a matrix with complete set of the Fourier coefficients. Note that if the pSrc in RCPack2D format is a real array of dimensions (NxM), then the pDst is a real array of dimensions (2xNxM). This should be taken into account when allocating memory for the function operation.

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.
