public EmfDeleteObject()Examples
L’exemple suivant montre comment définir la couleur d’arrière-plan pour EMF. Il met en fait un rectangle du coloris de fond avant de dessiner tous les autres objets.
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);
}
/// <summary>
/// Helper method to change EMF background.

public static void AddBackgroundRectangleEmf(Aspose.Imaging.FileFormats.Emf.EmfImage image, Aspose.Imaging.Color color)

{
return;
}
//Set Rectangle
Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfRectangle rectangle = new Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfRectangle();
rectangle.Box = image.Header.EmfHeader.Bounds;
//Set Brush
