Contoh berikut menunjukkan bagaimana menetapkan warna latar belakang untuk EMF. Ini sebenarnya meletakkan rektangle warna latar belakang sebelum menggambar semua objek lain.

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

{
AddBackgroundRectangleEmf((Aspose.Imaging.FileFormats.Emf.EmfImage)image, Aspose.Imaging.Color.Blue);
image.Save(outputFilePath);
