Translation variant, N phase export operation with an extra image

Pseudo code of the operation:

ExportOpExtra(In, Extra, ExportOp)
{
    for p = 1 to ExportOp.nrPhases();
    {
        ExportOp.init(p);
        foreach i, e in In, Extra
            ExportOp.doIt(In(i), Extra(e), i.x, i.y, i.z);
        ExportOp.done(p);
    }
}

The requirements on the ExportExtraT template parameter expressed as class definition are:

template<class ImValT, class ExtraValT>
class ExportExtraT
{
public:
    typedef HxTagTransVar       TransVarianceCategory;
    typedef HxTagNPhase         PhaseCategory;

                        ExportExtraT(HxTagList&);

    int                 nrPhases() const;
    void                init(int phase);
    void                doIt(const ImValT& imV, const ExtraValT& extraV,
                             int x, int y, int z);
    void                done(int phase);

    static HxString     className();
};

Example(s):

• instantiation : HxInstExportExtraIdentMaskCentralMoments_c, usage : HxIdentMaskCentralMoments
