Parameters

dstRoiSize	Size of the destination ROI in pixels.
mask	Predefined mask of IppiMaskSize type. Possible values are ippMskSize3x3 or ippMskSize5x5.
srcDataType	Data type of the source image.
dstDataType	Data type of the destination image.
numChannels	Number of channels in the image. Possible value is 1.
pBufferSize	Pointer to the size of the external work buffer.

Description

The ippiFilterSobelVertSecondBorderGetBufferSize function computes the size, in bytes, of the external work buffer needed for the ippiFilterSobelNegVertBorder function. The result is stored in the pBufferSize parameter.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when pBufferSize is NULL.
ippStsSizeErr	Indicates an error when dstRoiSize is negative, or equal to zero.
ippStsMaskSizeErr	Indicates an error when mask has an illegal value.
ippStsDataTypeErr	Indicates an error when srcDataType or dstDataType has an illegal value.
ippStsNumChannelsError	Indicates an error when numChannels has an illegal value.
