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 whenpBufferSizeis NULL.
- ippStsSizeErr
- Indicates an error whendstRoiSizeis negative, or equal to zero.
- ippStsMaskSizeErr
- Indicates an error whenmaskhas an illegal value.
- ippStsDataTypeErr
- Indicates an error whensrcDataTypeordstDataTypehas an illegal value.
- ippStsNumChannelsError
- Indicates an error whennumChannelshas an illegal value.
