public EmfSelectObject()Examples
Följande exempel visar hur du ställer in bakgrundsfärgen för EMF. Det sätter faktiskt en rektangel av bakgrundsfärgen innan du ritar alla andra objekt.
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

ObjectHandle
Få eller ställa in en 32-bitars icke-signat helhet som antingen anger indexet för ett grafiskt objekti EMF-objekttabellen eller indexet för ett lagerobjekt från Aspose.Imaging.FileFormats.Emf.Emf.Consts.EmfStockObject-förteckningen.
public int ObjectHandle { get; set; }
