Phase

Computes the phase of elements of a complex data image.

Syntax

IppStatus ippiPhase_<mod>(const Ipp<srcDatatype>* pSrc, int srcStep, Ipp<dstDatatype>* pDst, int dstStep, IppiSize roiSize);

Supported values for mod:

32fc32f_C1R

32fc32f_C3R

Include Files

ippi.h

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h

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

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.

roiSize

Size of the source and destination ROI in pixels.

Description

This function operates with ROI (see Regions of Interest in Intel IPP).

This function computes the phase in radians of elements of a source image pSrc given in complex data 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 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.
