How to: Enumerate Drawing Content of a Visual

The xref:System.Windows.Media.Drawing object provide an object model for enumerating the contents of a xref:System.Windows.Media.Visual.

Example

The following example uses the xref:System.Windows.Media.VisualTreeHelper.GetDrawing%2A method to retrieve the xref:System.Windows.Media.DrawingGroup value of a xref:System.Windows.Media.Visual and enumerate it.

Note

When you are enumerating the contents of the visual, you are retrieving xref:System.Windows.Media.Drawing objects, and not the underlying representation of the render data as a vector graphics instruction list. For more information, see WPF Graphics Rendering Overview.
