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:

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 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.
