        // Load an image
        string imagePath = @"..\..\..\data\table.png";
        Stream stream = new FileStream(imagePath, FileMode.Open, FileAccess.Read);
        var image = DXImage.FromStream(stream);

        // Create a new slide based on Object layout
        Slide slide = new Slide(SlideLayoutType.Object);

        // Find the Body placeholder shape on the slide
        var bodyPlaceholderShape = slide.Shapes.Find<Shape>(x => x.PlaceholderSettings.Type == PlaceholderType.Body);
        if (bodyPlaceholderShape != null) {
            // Get the actual bounds of the Body placeholder
            RectangleF rect = presentation.GetActualShapeBounds(slide, bodyPlaceholderShape);
            // Remove the Body placeholder shape
            slide.Shapes.Remove(bodyPlaceholderShape);
            // Add the image as a picture shape in the same position and size
            PictureShape picture = new PictureShape(image, rect.X, rect.Y, rect.Width, rect.Height);
            slide.Shapes.Add(picture);
        }

        // Add the new slide to the presentation
        presentation.Slides.Add(slide);

        // Save the modified presentation to a new PPTX file
        FileStream outputStream = new FileStream(@"D:\\saved-document.pptx", FileMode.Create);
