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 ifpSrcorpDstpointer isNULL.
- ippStsStepErr
- Indicates an error condition ifsrcStepordstStepvalue is zero or negative.
- ippStsSizeErr
- Indicates an error condition if width or height of images is less than or equal to zero.
