ippiFilter

I have trouble with filter functions. Why does the code given throw an exception? dimX is 336, dimY is 333. The incoming image is single channel Ipp32f* type.

Pulling my hair out.

Thanks!

bool GetSmoothImage(const ImageCoreC&pInMap, int dimX, int dimY) {
IppStatus ippStatus =ippStsNoErr;

int bytesperPix =sizeof(Ipp32f);

int filterWing = 1;

IppiSize srcSize = {dimX,dimY};

int srcStepOrg = srcSize.width * bytesperPix;

IppiSize roiSize = {dimX- (2*filterWing),dimY- (2*filterWing)};
　

int dstStep;

Ipp32f*pDst = ippiMalloc_32f_C1(srcSize.width,srcSize.height,&dstStep);

Ipp32f* pSrcStartpoint =pInMap.Data() + (filterWing * srcSize.width) + filterWing;

Ipp32f* pDstStartpoint = pDst + (filterWing * srcSize.width) + filterWing;
ippStatus = ippiFilterGauss_32f_C1R(pSrcStartpoint, srcStepOrg, pDstStartpoint, dstStep, roiSize,

ippMskSize3x3);
