Description
The
ippiFilterSobelVertBorderGetBufferSize
function computes the size, in bytes, of the external work buffer needed for the ippiFilterSobelVertBorder
function. The result is stored in the pBufferSize
parameter.For an example on how to use this function, see the code example provided with the
ippiFilterSobelVertBorder
function description.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.
