# DerivativeSpec data structure

## STRUCTURE

This structure is an aggregate of common parameters for derivative operators. Its current definition is:

    typedef struct
    {
       dip_DerivativeFlavour flavour;
       dip_float truncation;
    } dip_DerivativeSpec;

The enumerator `flavour` parameter is one of:

Name | Description
`DIP_DF_DEFAULT` | Default derivative flavour (==`DIP_DF_FIRGAUSS`)
`DIP_DF_FIRGAUSS` | Gaussian family, FIR implementation, `Gauss`
`DIP_DF_IIRGAUSS` | Gaussian family, IIR implementation, `GaussIIR`
`DIP_DF_FTGAUSS` | Gaussian family, FT implementation, `GaussFT`
`DIP_DF_FINITEDIFF` | Finite difference implementation, `FiniteDifferenceEx`
