}Properties
IhBrush
Dobivaju ili postavljaju 32-bitni nesignirani integrator koji određuje indeks logičkog objekta za brisanjeu tablici objekata EMF-a (odjeljak 3.1.1.1).Ovaj indeks treba sačuvati kako bi se ovaj objekt mogaoponovno korištena ili izmijenjena.
public int IhBrush { get; set; }Vrijednost nekretnina
LogBrush
Dobiva ili postavlja LogBrushEx objekt (odjeljak 2.2.12) koji određuje stil, boju ipolje BrushStyle u ovom objektu mora biti BS_SOLID,BS_HATCHED ili BS - NULL.
