How to: Use a Cached Element as a Brush
Use the xref:System.Windows.Media.BitmapCacheBrush class to reuse a cached element efficiently. To cache an element, create a new instance of the xref:System.Windows.Media.BitmapCache class and assign it to the element's xref:System.Windows.UIElement.CacheMode%2A property.
Example
The following code example shows how to reuse a cached element. The cached element is an xref:System.Windows.Controls.Image control that displays a large image. The xref:System.Windows.Controls.Image control is cached as a bitmap by using the xref:System.Windows.Media.BitmapCache class, and the cache is reused by assigning it to a xref:System.Windows.Media.BitmapCacheBrush. The brush is assigned to the background of twenty-five buttons to show efficient reuse.
