Description
The
ippiPhasePackGetBufferSize
function computes the size, in bytes, of
the external work buffer needed for the ippiPhasePack
function.
The result is stored in the pSize
parameter. Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error whenpSizeisNULL.
- ippStsSizeErr
- Indicates an error whendstRoiSizehas a field with a value less than 1.
- ippStsNumChannelsErr
- Indicates an error whennumChannelshas an illegal value.
