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 ifpSrc,pDstisNULL.
- ippStsSizeErr
- Indicates an error ifdstRoiSizehas a field with a zero or negative value.
- ippStsMaskSizeErr
- Indicates an error ifmaskSizehas a field with a zero or negative value.
- ippStsAnchorErr
- Indicates an error ifanchoris outside the mask size.
- ippStsMemAllocErr
- Indicates a memory allocation error.
