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
);

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.
