Parameters
ppSrcRow
Pointer to the set of rows.
pTaps
Pointer to the taps vector.
tapsLen
Length of taps vector, is equal to the number of rows.
pDst
Pointer to the destination row.
width
Width of the source and destination rows.

pTaps
and columns of the specified set of the rows
ppSrcRow
. It is useful for external vertical filtering pipeline implementation.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error.
ippStsNullPtrErr
Indicates an error condition if one of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error condition if
width
is less than or equal to 0.
