SumWindowColumn
Sums pixel values in the column mask applied to the image.
Syntax
IppStatus ippiSumWindowColumn_<mod>(const Ipp<srcDatatype>* pSrc, int srcStep, Ipp32f* pDst, int dstStep, IppiSize dstRoiSize, int maskSize, int anchor);
Supported values for mod:

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. |
dstRoiSize |
Size of the destination ROI in pixels. |
maskSize |
Size of the vertical column mask in pixels. |
anchor |
Anchor cell specifying the column mask alignment with respect to the position of the input pixel. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function sets each pixel in the destination image ROI pDst as the sum of all the source image pixels in the vertical column mask of size maskSize with the anchor cell anchor at the corresponding pixel in the source image ROI pSrc. To ensure valid operation when image boundary pixels are processed, the application must correctly define additional border pixels (see Borders in Neighborhood Operations).
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or a warning. |
ippStsNullPtrErr |
Indicates an error if pSrc, pDst is NULL. |
ippStsSizeErr |
Indicates an error if dstRoiSize has a field with a zero or negative value. |
ippStsMaskSizeErr |
Indicates an error if maskSize has a field with a zero or negative value. |
ippStsAnchorErr |
Indicates an error if anchor is outside the mask size. |
ippStsMemAllocErr |
Indicates a memory allocation error. |
