BitmapCache.RenderAtScale Property
Gets or sets the scale at which the object is rendered on the cached bitmap surface. Use this property for cached objects that are scaled to improve performance.
Namespace: System.Windows.Media
Assembly: System.Windows (in System.Windows.dll)
<BitmapCache RenderAtScale="double" .../>
Property Value
Type: System.DoubleThe scale at which the object is rendered as a cached bitmap. If you specify a negative number, an error will be thrown. The default is 1.
Dependency property identifier field: RenderAtScaleProperty
By default, when you set the CacheMode of a UIElement to a BitmapCache, the object is cached as a bitmap with a scale of 1 (its natural size). However, if you scale the cached UIElement, for example by using a ScaleTransform, set the RenderAtScale property to the same scale.
