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 (
N
x
M
), 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 ifpSrcorpDstpointer isNULL.
- ippStsStepErr
- Indicates an error condition ifsrcStepordstStepvalue is zero or negative.
- ippStsSizeErr
- Indicates an error condition ifsrcSizehas field with zero or negative value.
