LayerData Class

The LayerData class is used to hold a collection of AnnotationData objects, including other LayerData objects, allowing the annotations to be organized into layers.

Examples

The code below creates a LayerData object and adds a couple AnnotationData objects in addition to a sub layer.

LayerDataExample

Copy

LayerData mainLayer = new LayerData();

// Add a couple AnnotationData objects.
mainLayer.Items.Add(new EllipseData(new RectangleF(120, 12, 90, 180), new AnnotationBrush(Color.Red)));
mainLayer.Items.Add(new LineData(new AnnotationPen(Color.Blue, 2), new PointF(30, 30), new PointF(180, 180)));

// Add a sub layer object.
LayerData subLayer = new LayerData();
subLayer.Items.Add(new RectangleData(new RectangleF(10, 20, 120, 80), new AnnotationBrush(Color.BlueViolet)));
subLayer.Items.Add(new TextData("My TextData Object"));
mainLayer.Items.Add(subLayer);
