Libraries: ippcore.lib, ippvm.lib, ipps.lib

Parameters

roiSize	Maximum size of the destination ROI in pixels.
maskSize	Size of the filter mask in pixels.
dataType	Data type of the image. Possible values are: ipp8u, ipp16s, ipp16u, and ipp32f
numChannels	Number of channels in the image. Possible values are 1, 3, and 4.
pBufferSize	Pointer to the size, in bytes, of the external work buffer.

Description

This function operates with ROI (see Regions of Interest in Intel IPP).

This function computes the size, in bytes, of the external work buffer for the ippiSumWindow function. The result is stored in the pBufferSize parameter.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsSizeErr	Indicates an error if roiSize has a field with a zero or negative value.
ippStsMaskSizeErr	Indicates an error if maskSize has an illegal value.
ippStsDataTypeErr	Indicates an error if dataType has an illegal value.
ippStsNumChannelsError	Indicates an error if numChannels has an illegal value.
