How to: Create a Composite Drawing
This example shows how to use a xref:System.Windows.Media.DrawingGroup to create complex drawings by combining multiple xref:System.Windows.Media.Drawing objects into a single composite drawing.
Example
The following example uses a xref:System.Windows.Media.DrawingGroup to create a composite drawing from the xref:System.Windows.Media.GeometryDrawing and xref:System.Windows.Media.ImageDrawing objects. The following illustration shows the output that this example produces.

Note the gray border, which shows the bounds of the drawing.

You can use a xref:System.Windows.Media.DrawingGroup to apply a xref:System.Windows.Media.DrawingGroup.Transform%2A, xref:System.Windows.Media.DrawingGroup.Opacity%2A setting, xref:System.Windows.Media.DrawingGroup.OpacityMask%2A, xref:System.Windows.Media.DrawingGroup.BitmapEffect%2A, xref:System.Windows.Media.DrawingGroup.ClipGeometry%2A, or xref:System.Windows.Media.DrawingGroup.GuidelineSet%2A to the drawings it contains. Because a xref:System.Windows.Media.DrawingGroup is also a xref:System.Windows.Media.Drawing, it can contain other xref:System.Windows.Media.DrawingGroup objects.
The following example is similar to the preceding example, except that it uses additional xref:System.Windows.Media.DrawingGroup objects to apply bitmap effects and an opacity mask to some of its drawings. The following illustration shows the output that this example produces.

Note the gray border, which shows the bounds of the drawing.
