public EmfCreateBrushIndirect()Examples
L’exemple següent mostra com configurar el color de fons per a EMF. De fet, posa un rectangle del color del fons abans de dibuixar tots els altres objectes.
string dir = "c:\\aspose.imaging\\issues\\net\\3280\\";
string inputFilePath = dir + "image1.emf";
string outputFilePath = dir + "ChangeBackground_" + "image1.emf";

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