		// Initialize the viewer
		viewer = new Viewer();
		this.Controls.Add(viewer);
		// Subscribe to the ZoomChanged event
		viewer.ZoomChanged += Viewer_ZoomChanged;
	}
	private void Viewer_ZoomChanged(object sender, EventArgs e)
	{
		// Handle the ZoomChanged event
		// For example, update the status bar with the current zoom level
		statusBarLabel.Text = $"Zoom: {viewer.Zoom}%";
	}
