Følgende eksempel viser, hvordan du indstiller baggrundsfarven for EMF. Det placerer faktisk en rektangle af baggrundfarvet, før du tegner alle andre objekter.
string dir = "c:\\aspose.imaging\\issues\\net\\3280\\";
string inputFilePath = dir + "image1.emf";
string outputFilePath = dir + "ChangeBackground_" + "image1.emf";
using (Aspose.Imaging.FileFormats.Emf.MetaImage image = (Aspose.Imaging.FileFormats.Emf.MetaImage)Aspose.Imaging.Image.Load(inputFilePath))
{
AddBackgroundRectangleEmf((Aspose.Imaging.FileFormats.Emf.EmfImage)image, Aspose.Imaging.Color.Blue);
image.Save(outputFilePath);
}

//Set Rectangle

}Properties
IhBrush
Få eller indsætte en 32-bit usigned integrator, der angiver indekset for det logiske brushobjekti EMF-objekttabellen (sektion 3.1.1.1). Denne indeks skal gemmes, så dette objekt kan væregenbrugt eller ændret.
public int IhBrush { get; set; }Ejendomsværdi
LogBrush
modtager eller indsætter et LogBrushEx-objekt (sektion 2.2.12) som angiver stil, farve ogBrushStyle-feltet i dette objekt MUST være BS_SOLID,BS_HATCHED eller BS-NULL.
