Nasledujúci príklad ukazuje, ako nastaviť farbu pozadia pre EMF. V skutočnosti umiestňuje rektál farby pozadie pred kreslením všetkých ostatných objektov.

string inputFilePath = dir + "image1.emf";
string outputFilePath = dir + "ChangeBackground_" + "image1.emf";

image.Save(outputFilePath);

}Properties
IhBrush
Získať alebo nastaviť 32-bitový neoznačený integer, ktorý špecifikuje index logického brúsneho objektuv tabuľke objektov EMF (oddiel 3.1.1.1). tento index musí byť uložený tak, aby tento objekt mohol byťopätovne použitý alebo upravený.
public int IhBrush { get; set; }Hodnota nehnuteľnosti
LogBrush
Získava alebo nastaví objekt LogBrushEx (oddiel 2.2.12) ktorý špecifikuje štýl, farbu avzor logického brúska. pole BrushStyle v tomto objekte musí byť BS_SOLID,BS_HATCHED alebo BZ_NULL.
