SumWindowRow

Sums pixel values in the row mask applied to the image.

Syntax

IppStatus ippiSumWindowRow_<mod>(const Ipp<srcDatatype>* pSrc, int srcStep, Ipp32f* pDst, int dstStep, IppiSize dstRoiSize, int maskSize, int anchor);

Supported values for mod:

8u32f_C1R	16u32f_C1R	16s32f_C1R
8u32f_C3R	16u32f_C3R	16s32f_C3R
8u32f_C4R	16u32f_C4R	16s32f_C4R

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 horizontal row mask in pixels.
anchor	Anchor cell specifying the row 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 horizontal row 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.
