# 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](wpf-graphics-rendering-overview.md).
